Chapter 1
General System Monitoring
Considerations
System monitoring is an important aspect of switch operation. The Nortel
Ethernet Routing Switch 5500 Series provides a wide range of system monitoring options that allow the administrator to closely follow the operation of a switch or stack.
This chapter notes two general system monitoring considerations, system logging and port mirroring, that must be taken into account when using the
Nortel Ethernet Routing Switch 5500 Series. Subsequent chapters provide information on specific system monitoring tools and their use.
System logging
The Nortel Ethernet Routing Switch 5500 Series supports system logging
(syslog), a software tool to log system events for debugging and analysis.
To utilize the syslog, the switch applications that run in the Nortel Ethernet
Routing Switch 5500 Series, such as IGMP, MLT, STP, should be registered with the syslog tool.
Any events that happen in the above-mentioned applications can be logged with the help of the syslog tool. The logged events are stored in volatile
RAM, non-volatile RAM, or in a remote host. The storage location can be selected using the Command Line Interface (CLI).
Configuring the system log with the CLI
This section outlines the CLI commands used in the configuration and management of the system log.

Remote logging
The remote logging feature in Software Release 5.0 provides an enhanced level of logging by replicating system messages on a syslog server. System log messages from several switches can be collected at a central location, alleviating the network manager from querying each switch individually to interrogate the log files.
The remote syslog server must be configured and set up on the unit to log informational messages to this remote server. The UDP packet is sent to port 514 of the configured remote syslog server.
Once the IP address is in the system, syslog messages can be sent to the remote syslog server. If a syslog message is generated prior to capturing the IP address of the server, the system stores up to 10 messages that are sent once the IP address of the remote server is on the system.
This feature can be configured by enabling remote logging, specifying the
IP address of the remote syslog server, and specifying the severity level of the messages to be sent to the remote server.
Configuring remote logging with the CLI
Use the CLI to configure remote logging. This section discusses the commands that enable remote logging.

The
show logging
command displays the configuration and the current contents of the system event log. Refer to "

IGMP and the system event log
IGMP utilizes the components provided by the syslog tool. Functions such as storing messages in the NVRAM or remote host, and displaying these log messages through the CLI, console menu, or Telnet is then carried out by the syslog tool on its own.
The IGMP log events can be classified into the following three categories based on their severity:
•
Critical
•
Serious
•
Informational
IGMP logs in the messages whenever any of the following types of events take place in the system:
•
IGMP initialization
•
Configuration changes from the user
•
Stack Join events
•
IGMP messages -- Report, Leave and Query messages received by the switch
Note: Events such as reception of IGMP messages happen frequently in the switch, whenever a new host joins or leaves a group. Logging such messages consumes a lot of log memory.
Therefore, such messages should not be logged in all the time. By default, logging in of such messages is disabled. This feature must be enabled through the CLI to view such messages.
In
" IGMP syslog messages" (page 22)
:
•
%d represents a decimal value for the parameter preceding it. For example, 5 for VLAN 5
•
%x represents a hexadecimal value for the parameter preceding it. For example, 0xe0000a01 for Group 224.0.10.1
" IGMP syslog messages" (page 22)
describes the IGMP syslog messages and their severity.

Chapter 1 General System Monitoring Considerations
Port mirroring
A switch port can be designated to monitor traffic on any two specified switch ports (port-based) or to monitor traffic to or from any two specified addresses that the switch has learned (address-based).
Note: A probe device, such as the Nortel Networks StackProbe or equivalent, must be connected to the designated monitor port to use this feature. Contact a Nortel Networks sales agent for details about the StackProbe.
Port-based mirroring configuration
"Port-based mirroring example" (page 24)
shows an example of a port-based mirroring configuration in which port 20 is designated as the monitor port for ports 21 and 22 of Switch S1. Although this example shows ports 21 and 22 monitored by the monitor port (port 20), any of the trunk members of T1 and T2 can also be monitored.
In this example,
"Port-based mirroring example" (page 24)
shows port X and port Y as members of Trunk T1 and Trunk T2. Port X and port Y are not required to always be members of Trunk T1 and Trunk T2.
Note: Trunks cannot be monitored and trunk members cannot be configured as monitor ports.
Port-based mirroring example
In the configuration example shown in
"Port-based mirroring example"
, the designated monitor port (port 20) can be set to monitor traffic in any of the following modes:
•
Monitor all traffic received by port X.
•
Monitor all traffic transmitted by port X.
•
Monitor all traffic received and transmitted by port X.
•
Monitor all traffic received by port X or transmitted by port Y.

The total number of input datagrams received from interfaces, including those received in error.
The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options.
The number of input datagrams discarded because the IP address in the IP header destination field was not a valid address. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported Classes (for example, Class E). For addresses that are not IP Gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
The number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. For addresses that do not act as IP Gateways, this counter includes only those packets that were Source-Routed by way of this address and had successful Source-Route option processing.
The number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
The number of input IP datagrams for which no problems were encountered to prevent their continued processing but that were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting reassembly.
The total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
OutRequests The total number of IP datagrams that local IP user-protocols (including ICMP) supplied to IP in requests for transmission. Note that this counter does not include any datagrams counted in ipForwDatagrams.

The number of IP datagrams discarded because no route could be found to transmit them to their destination. Note that this counter includes any packets counted in ipForwDatagrams that meet this no-route criterion. Note that this includes any datagrams a host cannot route because all of its default gateways are down.
The number of IP datagrams that have been successfully fragmented at this entity.
The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, for example, because their Don’t Fragment flag was set.
The number of IP datagram fragments that have been generated as a result of fragmentation at this entity.
The number of IP fragments received that needed to be reassembled at this entity.
The number of IP datagrams successfully reassembled.
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, and so on). Note that this is not necessarily a count of discarded IP fragments because some algorithms
(notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.

Description
A count of frames for which reception on a particular MLT fails due to an internal
MAC sublayer receive error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the FrameTooLongs object, the AlignmentErrors object, or the
FCSErrors object.
The precise meaning of the count represented by an instance of this object is implementation specific. In particular, an instance of this object may represent a count of receive errors on a particular interface that are not otherwise counted.
The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular MLT. The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt.
A count of frames received on a particular
MLT that exceed the maximum permitted frame size. The count represented by an instance of this object is incremented when the frameTooLong status is returned by the MAC service to the LLC
(or other MAC user). Received frames for which multiple error conditions occur are, according to the conventions of
IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.
A count of times that the SQE TEST
ERROR message is generated by the
PLS sublayer for a particular MLT.
The SQE TEST ERROR message is defined in section 7.2.2.2.4 of ANSI/IEEE
802.3-1985 and its generation is described in section 7.2.4.6 of the same document.

The count represented by an instance of this object does not include frames involved in collisions.
A count of successfully transmitted frames on a particular MLT for which transmission is inhibited by exactly one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the corresponding instance of the
MultipleCollisionFrames object.
A count of successfully transmitted frames on a particular MLT for which transmission is inhibited by more than one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the corresponding instance of the
SingleCollisionFrames object.
The number of times that a collision is detected on a particular MLT later than
512 bit-times into the transmission of a packet. Five hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mb/s system. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.
A count of frames for which transmission on a particular MLT fails due to excessive collisions.

Configuring Remote Network
Monitoring (RMON)
The Remote Network Monitoring (RMON) Management Information Base
(MIB) is an interface between the RMON agent on the Nortel Ethernet
Routing Switch 5500 Series and an RMON management application, such as the Java Device Manager.
It defines objects that are suitable for the management of any type of network, but some groups are targeted for Ethernet networks in particular.
The RMON agent continuously collects statistics and proactively monitors switch performance.
RMON has three major functions:
•
Creating and displaying alarms for user-defined events
•
Gathering cumulative statistics for Ethernet interfaces
•
Tracking a history of statistics for Ethernet interfaces
Configuring RMON with the CLI
This section describes the CLI commands used to configure and manage
RMON.

Configuring RMON with the Web-based Management Interface
This section discusses the configuration and management of RMON using the Web-based Management Interface.
Configuring RMON fault threshold parameters
Alarms are used to alert a system administrator when the value of a variable goes out of range. RMON alarms can be defined on any MIB variable that resolves to an integer value. String variables (such as system description) cannot be used as alarm variables.
Creating an RMON fault threshold
To configure an RMON fault threshold, follow this procedure:
Step Action
1
Open the RMON Threshold screen by selecting Fault > RMON
Threshold from the menu. This screen is illustrated below.

Field
Interval
Alarm Sample
Description
Type the time period (in seconds) to sample data and compare the data to the rising and falling thresholds.
Choose the sampling method:
Absolute: Absolute alarms are defined on the current value of the alarm variable. An example of an alarm defined with absolute value is card operating status.
Because this value is not cumulative, but instead represents states, such as card up (value 1) and card down (value 2), you set it for absolute value.
Therefore, an alarm could be created with a rising value of 2 and a falling value of 1 to alert a user to whether the card is up or down.
Delta: Most alarm variables related to Ethernet traffic are set to delta value. Delta alarms are defined based on the difference in the value of the alarm variable between the start of the polling period and the end of the polling period. Delta alarms are sampled twice per polling period. For each sample, the last two values are added together and compared to the threshold values. This process increases precision and allows for the detection of threshold crossings that span the sampling boundary. Therefore, if you keep track of the current values of a given delta-valued alarm and add them together, the result is twice the actual value. (This result is not an error in the software.)
Click Submit.

Viewing the RMON fault event log
RMON events and alarms work together to produce notification when values in the network go out of a specified range. When values pass the specified ranges, the alarm is triggered. The event specifies how the activity is recorded.
An event specifies whether a trap, a log, or a trap and a log are generated to view alarm activity. When RMON is globally enabled, two default events are generated:
•
Rising Event
•
Falling Event
Default events specify that when an alarm goes out of range, the firing of the alarm is tracked in both a trap and a log. For example, when an alarm fires at the rising threshold, the rising event specifies that this information be sent to both a trap and a log. The RMON Event Log screen works in conjunction with the RMON Threshold screen to enable viewing the history of RMON fault events.
To view a history of RMON fault events, follow this procedure:
Step Action
1
Open the RMON Event Log screen by selecting Fault > RMON
Event Log from the menu. This screen is illustrated below.

Chapter 3 Configuring Remote Network Monitoring (RMON)
Viewing history
Ethernet history records periodic statistical samples from a network. A sample is called a history and is gathered in time intervals referred to as
"buckets."
Histories establish a time-dependent method for gathering RMON statistics on a port. The default values for history are:
•
Buckets are gathered at 30-minute intervals.
•
Number of buckets gathered is 50.
Both the time interval and the number of buckets is configurable. However, when the last bucket is reached, bucket 1 is dumped and "recycled" to hold a new bucket of statistics. Then bucket 2 is dumped, and so forth.
To view RMON history:
Step Action

Open the RmonControl screen by selecting Serviceability >
RMON > Control from the menu. This screen is illustrated in below.

Creating a history
RMON can be used to collect statistics at intervals. For example, if switch performance will be monitored over a weekend, enough buckets to cover two days must be set aside. To do this, set the history to gather one bucket each hour, thus covering a 48-hour period. After history characteristics are set, they cannot be modified; the history must be deleted and another created.
To establish a history for a port and set the bucket interval:

Description
The number of discrete sampling intervals over which data is saved in the part of the media-specific table associated with this entry. There are instances when the actual number of buckets associated with this entry is less than the value of this object. In this case, at the end of each sampling interval, a new bucket is added to the media-specific table.
The interval in seconds over which the data is sampled for each bucket in the part of the media-specific table associated with this entry. You can set this interval to any number of seconds between 1 and 3600 (1 hour). Because the counters in a bucket may overflow at their maximum value with no indication, note the possibility of overflow in any of the associated counters.
It is important to consider the minimum time in which any counter could overflow on a particular media type and set the historyControlInterval object to a value less than this interval.
This is typically most important for the octets counter in any media-specific table. For example, on an Ethernet network, the etherHistoryOctets counter could overflow in about one hour at the Ethernet’s maximum utilization.

Alarms
Alarms are useful when you need to know when the values of a variable go out of range. Define an RMON alarm for any MIB variable that resolves to an integer value. String variables cannot be used. All alarms share the following characteristics:
•
An upper and lower threshold value is defined.
•
A corresponding rising and falling event occurs.
•
An alarm interval or polling period is reached.
When alarms are activated, view the activity in a log or a trap log, or a script can be created to provide notification by beeping a console, sending e-mail messages, or calling a pager.

103
How RMON alarms work
The alarm variable is polled and the result is compared against upper and lower limit values you select when you create the alarm. If either limit is reached or crossed during the polling period, then the alarm fires and generates an event that you can view in the event log or the trap log.
The upper limit of the alarm is called the rising value, and its lower limit is called the falling value. RMON periodically samples the data based upon the alarm interval. During the first interval that the data passes above the rising value, the alarm fires as a rising event. During the first interval that the data drops below the falling value, the alarm fires as a falling event
(
).
How alarms fire
It is important to note that the alarm fires during the first interval that the sample goes out of range. No additional events are generated for that threshold until the opposite threshold is crossed. Therefore, it is important to carefully define the rising and falling threshold values for alarms to work as expected. Otherwise, incorrect thresholds cause an alarm to fire at every alarm interval.
A general guideline is to define one of the threshold values to an expected baseline value, and then define the opposite threshold as the out-of-bounds limit. Because of sample averaging, the value may be equal to ±1 of the baseline units. For example, assume an alarm is defined on octets going out of a port as the variable. The intent of the alarm is to provide notification to the system administrator when excessive traffic occurs on that port. If spanning tree is enabled, then 52 octets are transmitted out of the port every
2 seconds, which is equivalent to baseline traffic of 260 octets every 10 seconds. This alarm should provide the notification the system administrator needs if the lower limit of octets going out is defined at 260 and the upper limit is defined at 320 (or at any value greater than 260 + 52 = 312).
The first time outbound traffic other than spanning tree Bridge Protocol Data
Units (BPDU) occurs, the rising alarm fires. When outbound traffic other than spanning tree ceases, the falling alarm fires. This process provides the system administrator with time intervals of any non-baseline outbound traffic.

Chapter 3 Configuring Remote Network Monitoring (RMON)
If the alarm is defined with a falling threshold less than 260 (assuming the alarm polling interval is 10 seconds), say 250, then the rising alarm can fire only once (
"Alarm example - threshold less than 260" (page 104) ). The
reason is that for the rising alarm to fire a second time, the falling alarm (the opposite threshold) must fire. Unless the port becomes inactive or spanning tree is disabled (which would cause the value for outbound octets to drop to zero), the falling alarm cannot fire because the baseline traffic is always greater than the value of the falling threshold. By definition, the failure of the falling alarm to fire prevents the rising alarm from firing a second time.

Creating alarms
When creating an alarm, select a variable from the variable list and a port, or other switch component, to which it is connected. Some variables require port IDs, card IDs, or other indices (for example, spanning tree group IDs).
Then select a rising and a falling threshold value. The rising and falling values are compared against the actual value of the variable that you choose. If the variable falls outside of the rising or falling value range, an alarm is triggered and an event is logged or trapped.
When an alarm is created a sample type is also selected, which can be either absolute or delta. Absolute alarms are defined on the cumulative value of the alarm variable. An example of an alarm defined with absolute value is card operating status. Because this value is not cumulative, but instead represents states, such as card up (value 1) and card down (value
2), you set it for absolute value. Therefore, an alarm could be created with a rising value of 2 and a falling value of 1 to alert a user to whether the card is up or down.
Most alarm variables related to Ethernet traffic are set to delta value. Delta alarms are defined based on the difference in the value of the alarm variable between the start of the polling period and the end of the polling period.
Delta alarms are sampled twice per polling period. For each sample, the last two values are added together and compared to the threshold values.
This process increases precision and allows for the detection of threshold

Field Description
Sample Type The method of sampling the selected variable and calculating the value to be compared against the thresholds. If the value of this object is absoluteValue(1), the value of the selected variable will be compared directly with the thresholds at the end of the sampling interval. If the value of this object is deltaValue(2), the value of the selected variable at the last sample will be subtracted from the current value, and the difference compared with the thresholds.
Value The value of the statistic during the last sampling period. For example, if the sample type is deltaValue, this value is the difference between the samples at the beginning and end of the period. If the sample type is absoluteValue, this value is the sampled value at the end of the period. This is the value that is compared with the rising and falling thresholds. The value during the current sampling period is not made available until the period is completed and remains available until the next period is completed.
StartupAlarm The alarm that may be sent when this entry is first set to Valid.
If the first sample after this entry becomes valid is greater than or equal to the risingThreshold and alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3), then a single rising alarm is generated. If the first sample after this entry becomes valid is less than or equal to the fallingThreshold and alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3), then a single falling alarm is generated.
RisingThres hold
A threshold for the sampled statistic. When the current sampled value is greater than or equal to this threshold, and the value at the last sampling interval was less than this threshold, a single event is generated. A single event is also generated if the first sample after this entry becomes valid is greater than or equal to this threshold and the associated alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3). After a rising event is generated, another such event is not generated until the sampled value falls below this threshold and reaches the alarmFallingThreshold.
RisingEventI ndex
The index of the eventEntry that is used when a rising threshold is crossed. The eventEntry identified by a particular value of this index is the same as identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In particular, if this value is zero, no associated event is generated, because zero is not a valid event index.

Description
A threshold for the sampled statistic. When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single event is generated. A single event is also generated if the first sample after this entry becomes valid is less than or equal to this threshold and the associated alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3). After a falling event is generated, another such event is not generated until the sampled value rises above this threshold and reaches the alarmRisingThreshold.
The index of the eventEntry that is used when a falling threshold is crossed. The eventEntry identified by a particular value of this index is the same as identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In particular, if this value is zero, no associated event is generated, because zero is not a valid event index.
The network management system that created this entry.
The status of this alarm entry.
Events
RMON events and alarms work together to provide notification when values in the network are outside of a specified range. When values pass the specified ranges, the alarm is triggered. The event specifies how the activity is recorded.
How events work
An event specifies whether a trap, a log, or a trap and a log are generated to view alarm activity. When RMON is globally enabled, two default events are generated:
•
RisingEvent
•
FallingEvent
The default events specify that when an alarm goes out of range, the
"firing" of the alarm will be tracked in both a trap and a log. For example, when an alarm fires at the rising threshold, the rising event specifies that this information be sent to both a trap and a log. Likewise, when an alarm passes the falling threshold, the falling event specifies that this information be sent to a trap and a log.

IP Flow Information Export (IPFIX)
IP Flow Information Export (IPFIX) is a protocol used for the export of flow information from traffic observed on a switch. Since IPFIX is still in development with the IETF, the current implementation is based on Netflow
V9.
IP traffic is sampled and classified into different flows based the following parameters:
•
protocol type
•
destination IP address
•
source IP address.
•
ingress port
•
TOS
If the protocol type is TCP or UDP, a flow is defined by two additional parameters:
•
source port
•
destination port
Software Release 5.0 supports IPFIX through the creation and display of sampled information as well as the ability to export this sampled information.
IPFIX functionality can be accessed through the Java Device Manager of
Web-based Management Interface.
Note: The IPFIX feature shares resources with QoS. If the IPFIX feature is enabled, a QoS policy precedence will be used.
For further information about QoS policies, refer to the Nortel Ethernet
Routing Switch 5500 Series Configuration - Quality of Service (Part
Number NN47200-504).

IPFIX Configuration using the Command Line Interface
This section describes the commands used in the configuration and management of IPFIX using the CLI.
ip ipfix collector command
The
ip ipfix collector
command is used to configure IPFIX collectors. IPFIX collectors are used to collect and analyze data exported from an IPFIX complaint switch. In Software Release 5.0, the only external collector supported is NetQOS. At this time, up to two collectors can be supported.
IPFIX data is exported from the switch in Netflow version 9 format. Data is exported using UDP port 9995.
Note: IPFIX data is not load balanced when two collectors are in use.
Identical information is sent to both collectors.
The syntax of the
ip ipfix collector
command is:
ip ipfix collector <unit_number> <collector_ip_address>
[dest-port <destination_port>] [enable] [exporter-ip
<exporter_ip_address>]
The following table describes the parameters for this command.
ip ipfix collector Parameters
Parameter
<unit_number>
Description
The unit number of the collector. Currently up to two collectors are supported so the values 1 or 2 are valid.
The IP address of the collector.
<collector_ip_ad dress>
<destination_po rt>
<exporter_ip_ad dress>
The port on which the collector will be listening for IPFIX data. Currently only port 9995 is supported for this task.
The IP address of the IPFIX exporter.
The
ip ipfix collector
command is executed in the Global
Configuration mode.
