I NTRODUCTION
The switch can be managed through the switch’s serial port,
TELNET, or the Web-based management agent. The Command
Line Interface (CLI) can be used to configure and manage the
switch via the serial port or TELNET interfaces. Before using
in-band system management tools such as TELNET or the
Web-based management software, it is necessary to configure
IP settings and setup user accounts. IP settings configuration
is discussed in this chapter and user accounts setup (create
accounts, config accounts) is described in Chapter 4.
This manual provides a reference for all of the commands
contained in the CLI. Configuration and management of the
switch via the web-based management agent is discussed in
the User’s Guide.
Accessing the Switch via the Serial Port
Use the RJ-45 console port on the front panel of the DES-7003
management module for the initial configuration. To use the
console port, you can run terminal emulation software on a
computer or use a VT100-compatible terminal. You will need
the RJ-45 to DB-9 (RS-232) adapter included with you
shipment to complete the console connection.
To establish a console connection to the Switch:
1. Insert the RJ-45 to DB-9 adapter into the RJ-45
console port on the front panel of the active primary
master management/CPU module. The console port is
labeled and is located next to the LED indicators.
2. Attach the female end of the RS-232 cable (included
with shipment) to the male RS-232 connector on the
adapter.
3. Connect the RS-232 cable to a standard COM port on a
computer.
1
4. The RS-232 connection to the computer should be
configured as follows:
§
Baud rate = 9600
§
Parity = none
§
Data bits = 8
§
Stop bits = 1
§
Flow control = none
Make sure the terminal or computer you are using to make
this connection is configured to match these settings.
With the serial port properly connected to a management
computer, the following screen should be visible. If this screen
does not appear, try pressing Ctrl+r to refresh the console
screen.
Each DES-7003 CPU management module is assigned a
unique MAC address by the factory. This MAC address cannot
be changed, and can be found from the initial boot console
screen – shown below.
Figure 1- 1. Boot Screen
The MAC address of the CPU module can also be viewed by
requesting a list of basic information about the switch (see
show switch command in Chapter 4).
2
Figure 1- 2. Initial Console Screen User Name Prompt
There is no initial username or password. Just press the enter
key at the User Name prompt and again at the Passwrod
prompt to display the CLI input cursor − DES7000:4@# (or
DES7100:4@# for the DES-7100). This is the command line
where all commands are input.
3
Setting the Switch’s IP Address
The DES-7000 series switch must have a TCP/IP address
assigned to it so that a network management system (Webbased, TELNET, etc.) can find it on the network. You can use
the console manager to access the system’s management
software to view or change it’s IP settings.
The IP address for the switch must be set before it can be
managed with the web-based manager or TELNET session.
The switch IP address can be automatically set using BOOTP
or DHCP protocols, in which case the actual address assigned
to the switch must be known.
The IP address may be set using the Command Line Interface
(CLI) over the console serial port as follows:
1. Starting at the command line prompt DES7000:4@# −
enter the commands config ip ipaddress
xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s
represent the IP address to be assigned to the switch and
the y’s represent the corresponding subnet mask.
2. Alternaltively, you can enter DES7000:4@# − enter the
commands config ip ipaddress xxx.xxx.xxx.xxx/z.
Where the x’s represent the IP address to be assigned to
the IP interface and the z represents the corresponding
number of subnets in CIDR notation.
The IP interface on the switch can be assigned an IP address
and subnet mask and can then be used to connect a
management station to the switch’s TELNET or web-based
management agent.
It may be necessary to designate a default gateway to allow
packets to be sent outside the switch’s subnet. You can do this
manually by typing the command config ip gateway
xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy or config ip gateway
xxx.xxx.xxx.xxx/z.
The may also be configured to obtain IP settings automatically
from a BOOTP or DHCP server. In this case the switch gets its
IP settings including gateway IP from a server. Please read
Chapter 5, Switch IP Configuration for a complete description
of the config ip command set.
4
Figure 1- 3. Assigning the Switch an IP Address
In the above example, the switch was assigned an IP address of
10.1.1.1 with a subnet mask of 255.255.255.0. The system
message Success indicates that the command was executed
successfully. The switch can now be configured and managed
via TELNET and the CLI or via the Web-based management
agent using the above IP address to connect to the switch
through the Management port (labeled: Mgmt) on the CPU
module, or through the network.

U SING
THE
C ONSOLE CLI
The DES-7000 supports a console management interface that
allows the user to connect to the switch’s management agent
via a serial port and a terminal or a computer running a
terminal emulation program. The console can also be used
over the network using the TCP/IP TELNET protocol. The
console program can be used to configure the switch to use an
SNMP-based network management software over the network.
This chapter describes how to use the console interface to
access the switch, change its settings, and monitor its
operation.
Note: Switch configuration settings are saved to non-volatile RAM using
the save command. The current configuration will then be retained in the
switch’s NV-RAM, and reloaded when the switch is rebooted. If the switch
is rebooted without using the save command, the last configuration saved to
NV-RAM will be loaded.
Connecting to the Switch
The console interface is used by connecting the Switch to a
VT100-compatible terminal or a computer running an ordinary
terminal emulator program (e.g., the Hyper Terminal program
included with the Windows operating system). You will need
the RJ-45 to DB-9 (RS-232) adapter nd using an RS-232C
serial cable included with you shipment to complete the
console connection. Your terminal parameters will need to be
set to:
•
•
•
•
•
•
VT-100/ANSI compatible
9,600 baud
8 data bits
No parity
One stop bit
No flow control
You can also access the same functions over a TELNET
interface. Once you have set an IP address for your Switch, you
6
can use a TELNET program (in VT-100 compatible terminal
mode) to access and control the Switch. All of the screens are
identical, whether accessed from the console port or from a
TELNET interface.
After the switch reboots and you have loged in, the console
looks like this:
Figure 2-1. Initial Console Screen
Commands are entered at the command prompt, DES-7000:4#.
There are a number of helpful features included in the CLI.
Entering the ? command will display a list of all of the top-level
commands.
7
Figure 2-2. The ? Command
The dir command has the same function as the ? command.
When you enter a command without its required parameters,
the CLI will prompt you with a Next possible completions:
message.
Figure 2-4. Example Command Parameter Help
In this case, the command config account was entered
without the parameter <username>. The CLI will then prompt
you to enter the <username> with the message, Next possible
completions:. Every command in the CLI has this feature, and
complex commands have several layers of parameter
prompting.
All commands in the CLI function in this way. In addition, the
syntax of the help prompts are the same as presented in this
manual − angle brackets < > indicate a numerical value or
character string, braces { } indicate optional parameters or a
choice of parameters, and brackets [ ] indicate required
parameters.
If a command is entered that is unrecognized by the CLI, the
top-level commands will be displayed under the Available
commands: prompt.
8
Figure 2-6. The Available Commands Prompt
The top-level commands consist of commands like show or
config.
Most of these commands require one or more
parameters to narrow the top-level command.
This is
equivalent to show what? or config what? Where the what? is
the next parameter.
For example, if you enter the show command with no
additional parameters, the CLI will then display all of the
possible next parameters.
9
Figure 2-6. Next possible completions: Show Command
In the above example, all of the possible next parameters for
the show command are displayed. At the next command
prompt, the up arrow was used to re-enter the show command,
followed by the account parameter. The CLI then displays the
user accounts configured on the switch.

enable traffic-segmentation
Purpose
Used to enable traffic segmetation system
wide.
Syntax
enable traffic-segmentation
Description
Traffic segmentation is used to limit the
broadcast domain of indivudual ports.
When traffic segmentation is enabled, the
ports on the switch slave blade modules
have a limited broadcast domain. In effect,
a separate VLAN is created for each port
that includes the port plus the Master CPU
and its uplink ports. This arrangement is
sometimes referred to as Asymettric VLAN.
When traffic segmentation is enabled, the
ports on the switch slave blade modules are
segmented so they are unable to
communicate with ports that share the
same slave blade module. Ports are not
restricted from communication with ports
on different modules.
Parameters
None.

Each command is listed, in detail, in the following sections.
Note: Commands that use a <portlist> parameter allow you to specify a
sequential range of ports or a single port on the switch. The port list is
specified by listing the lowest slot number and the beginning port number
on that slot, separated by a colon. Then highest slot number, and the
highest port number of the range (also separeted by a colon) are specified.
The beginning and end of the port list range are seperated by a dash. For
example, 6:1 would specify module in slot number 6, port 1. 7:24 specifies
module in slot number 7, port 24. 6:1-7:24 specifies all of the ports
between module 6, port 1 and module 7, port 24 − in numerical order. For a
single port, just enter the slot number and port number separated by a
colon.
124
config 802.1p default_priority
Purpose
Used to configure the 802.1p default
priority settings on the switch.
If an
untagged packet is received by the switch,
the priority configured with this command
will be written to the packet’s priority field.
Syntax
config 802.1p default_priority
[<portlist>/all] <priority>
Description
This command allows you to specify default
priority handling of untagged packets
received by the switch. The priority value
entered with this command will be used to
determine which of the four hardware
priority queues the packet is forwarded to.
Parameters
<portlist> − This specifies a range of ports
for which the default priority is to be
configured.
all − Specifies that the command applies to
all ports on the switch.
<priority> − The priority value you want to
assign to untagged packets received by the
switch or a range of ports on the switch.
Restrictions
Only administrator-level users can issue
this command.
Example Usage:
DES7100:4#config 802.1p default_priority all 5
Command: config 802.1p default_priority all 5
Success.
DES7100:4#
125
config 802.1p user_priority
Purpose
Used to map the 802.1p user priority of an
incoming packet to one of the four
hardware queues available on the switch.
Syntax
config 802.1p user_priority <priority>
<class_id>
Description
This command allows you to configure the
way the switch will map an incoming
packet, based on its 802.1p user priority, to
one of the four available hardware priority
queues on the switch.
The switch’s default is to map the following
incoming 802.1p user priority values to the
four hardware priority queues:
802.1p

You can change this mapping by specifying
the 802.1p user priority you want to go to
the <class_id> (the number of the hardware
queue).
126
config 802.1p user_priority
<priority> − The 802.1p user priority you
want to associate with the <class_id> (the
number of the hardware queue) with.
<class_id> − The number of the switch’s
hardware priority queue. The switch has
four hardware priority queues available.
They are numbered between 0 (the highest
priority) and 3 (the lowest priority).
Restrictions
Only administrator-level users can issue
this command.
Example Usage:
DES7100:4# config 802.1p user_priority 1 3
Command: config 802.1p user_priority 1 3
Success.
DES7100:4#
127
config scheduling
Purpose
Used to configure the traffic scheduling
mechanism for each COS queue.
Syntax
config scheduling <class_id> [max_packet
<value>]
Description
The switch contains 4 hardware priority
queues. Incoming packets must be mapped
to one of these four queues. This command
is used to specify the rotation by which
these four hardware priority queues are
emptied.
The switch’s default (if the config
scheduling command is not used, or if the
config scheduling command is entered
with max_packet set to 0) is to empty the 4
hardware priority queues in order − from
the highest priority queue (hardware queue
0) to the lowest priority queue (hardware
queue 3).
Each hardware queue will
transmit all of the packets in its buffer
before allowing the next lower priority
queue to transmit its packets. When the
lowest hardware priority queue has finished
transmitting all of its packets, the highest
hardware priority queue can again transmit
any packets it may have received.
128
config scheduling
Description
The max_packets parameter allows you to
specify the maximum number of packets a
given hardware priority queue can transmit
before allowing the next lowest hardware
priority queue to begin transmitting its
packets. A value between 0 and 255 can be
specified. For example, if a value of 3 is
specified, then the highest hardware
priority queue (number 0) will be allowed to
transmit 3 packets − then the next lowest
hardware priority queue (number 1) will be
allowed to transmit 3 packets, and so on,
until all of the queues have transmitted 3
packets. The process will then repeat.
When the specified hardware priority queue
has been waiting to transmit packets for
this amount of time, the current queue will
finish transmitting its current packet, and
then allow the hardware priority queue
whose max_latency timer has expired to
begin transmitting packets.
Parameters
<class_id> − This specifies which of the four
hardware priority queues the config
scheduling command will apply to. The
four hardware priority queues are identified
by number − from 0 to 3 − with the 0 queue
being the lowest priority.
max_packet <value> − Specifies the
maximium number of packets the above
specified hardware priority queue will be
allowed to transmit before allowing the next
lowest priority queue to transmit its
packets. A value between 0 and 255 can be
specified.
Restrictions
Only administrator-level users can issue
this command.

Note: Commands that use a <portlist> parameter allow you to specify a
sequential range of ports or a single port on the switch. The port list is
specified by listing the lowest slot number and the beginning port number
on that slot, separated by a colon. Then highest slot number, and the
highest port number of the range (also separeted by a colon) are specified.
The beginning and end of the port list range are seperated by a dash. For
example, 6:1 would specify module in slot number 6, port 1. 7:24 specifies
module in slot number 7, port 24. 6:1-7:24 specifies all of the ports
between module 6, port 1 and module 7, port 24 − in numerical order. For a
single port, just enter the slot number and port number separated by a
colon.

config igmp_snooping querier
Purpose
Syntax
Description
Parameters
Used to configure the time in seconds
between general query transmissions, the
maximum time in seconds to wait for
reports from members, the permitted
packet
loss
that
guarantees
IGMP
snooping.
config igmp_snooping querier
[<vlan_name>/all] {query_interval
<sec>/max_response_time
<sec>/robustness_variable
<value>/last_member_query_interval
<sec>/state [enabled/disabled]
This command configures IGMP snooping
querier.
<vlan_name> − The name of the VLAN for
which IGMP snooping querier is to be
configured.
query_interval <sec> − Specifies the amount
of time in seconds between general query
transmissions. The default setting is 125
seconds.
max_response_time <sec> − Specifies the
maximum time in seconds to wait for
reports from members. The default setting
is 10 seconds.
robustness_variable <value> − Provides
fine-tuning to allow for expected packet loss
on a subnet. The value of the robustness
variable is used in calculating the following
IGMP message intervals:
§ Group member interval— Amount of
time that must pass before a
multicast router decides there are no
more members of a group on a
network. This interval is calculated as
follows: (robustness variable x query
interval) + (1 x query response
interval).
157
config igmp_snooping querier
Parameters
Restrictions
158
•
Other querier present interval—
Amount of time that must pass
before a multicast router decides
that there is no longer another
multicast router that is the querier.
This interval is calculated as
follows: (robustness variable x query
interval) + (0.5 x query response
interval).
• Last member query count— Number
of group-specific queries sent before
the router assumes there are no
local members of a group. The
default number is the value of the
robustness variable.
• By default, the robustness variable
is set to 2. You might want to
increase this value if you expect a
subnet to experience significant
packet loss.
last_member_query_interval <sec> − The
maximum amount of time between groupspecific query messages, including those
sent in response to leave-group messages.
You might lower this interval to reduce the
amount of time it takes a router to detect
the loss of the last member of a group.
state [enabled/disabled] − Allows the switch
to be specified as an IGMP Querier or Nonquerier.
Only administrator-level users can issue
this command.
Example Usage:
To configure the igmp snooping:
DES7000:4@#config igmp_snooping querier default
query_interval 125 state enabled
Command: config igmp_snooping querier default
query_interval 125 state enabled
