3.1 Target Management
Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use
the Automatic Target Management feature in the ATTO ExpressNAV interface.
CAUTION
Changing the device map can affect the
host’s view of devices and your application
configuration
To map Fibre Channel devices, you must connect the
devices to one of the iPBridge Fibre Channel ports. To
access mapped Fibre Channel devices over Ethernet,
you must have a host computer connected to one of
the iPBridge iSCSI data ports.
The default is set up as a single target node in which
a host or initiator views the iPBridge as a single iSCSI
node with all available devices shown as LUNs on a
single iSCSI target.
If you decide to change the automatic mapping set up
when you powered up the iPBridge, you have two
options to map devices after you disable automatic
mapping:
• You may map devices manually to the single
default node.
•
You may map each device to its own target to
break the single iSCSI target node into multiple
nodes. Multiple target nodes allow greater
flexibility to grant or deny access between
initiators and devices.
If you divide the default single target node into multiple
target nodes, you must set up access to each node
separately.
See Exhibit 3.1-1 on page 13 to see the difference
between single target node and multiple target nodes.
Target names
Each iSCSI target node accessed through the
Ethernet port on an iPBridge is identified by a unique
world-wide iSCSI-qualified name. This format
references the iPBridge serial number and target node
name:
iqn.1995-12.com.attotech:ipbridge:
serialnumber <targetname>
Default target node
The default target is set as a single target with Access
Control (ACL) disabled and CHAP authentication
disabled. The default target node cannot be deleted.
The iPBridge maps devices automatically although
you can map devices yourself.

appropriate LUN on the left.
Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
Multiple target nodes
Multiple targets allow you to create a more
configurable mapping scheme which can segregate
storage into different iSCSI nodes within the iPBridge,
with each iSCSI target having its own set of access
criteria.
For example, if you have two servers and a library with
four tapes and a media changer, the default node
would provide both servers access to all tapes and the
media changer (default target mode).
If you configured multiple target nodes, you are able to
map some devices to one server and other devices to
the other server, requiring separate user names and
passwords for access using various methods including
Access Control Lists, iSNS and CHAP authentication.
Consult with your network administrator and refer to
Exhibit 3.1-1.
Note
If actual storage is mapped to more than one
iSCSI target and a server has authorization for
both targets, the server could show duplicate
storage without any warning to the user.
You may use either of two methods to control access
to storage: Access Control Lists or CHAP
authentication.
Access Control lists: each target iqn has its own
access control. The iPBridge will check the initiator’s
iqn before allowing access.
CHAP to control access: different CHAP account
names and CHAP secrets are assigned to each target.

3.2 iSCSI Configuration
You may fine-tune the iPBridge using the ATTO ExpressNAV interface.
Several special iPBridge features may be accessed
using the ExpressNAV graphical user interface. For
details on each command, refer to CLI provides an
ASCII-based interface on page i of the Appendix
1 If you are not already in the ExpressNAV
interface, type the IP address of your iPBridge
in a standard browser as found in Using
ExpressNAV on page 27, click Enter Here,
type in your user name and password, and click
OK.
2 The Status page appears. Click on the menu
item which regulates the parameter you wish to
change.
• Ethernet: iSCSI port number
• iSCSI iSCSI Alias, ISNS Login Control,
iSNSServer, Speedwrite
• CHAP commands: iSCSI Chap Secret, iSCSI
Target through the Manual Target Mgt
menu
3 Click Submit on each page after you have
made changes to save your choices. When you
have completed all changes, go to the Restart
page and click on Restart.
Ethernet
Click on the Ethernet menu item.
iSCSI Port Number
Specifies the port number whereby the iPBridge listens
for iSCSI connections. The port number must be between
1024 and 65535 except for port 860. The default is 3260.
iSCSI
Click on the iSCSI menu item.
iSCSI Alias
Provides a human-readable name assigned to the
iPBridge. Aliases may be 1 to 64 characters long and may
contain spaces if spaces are enclosed in quotation
marks. The default is a blank space.
iSNS Login Control
Specifies whether the iPBridge will delegate its access
control/authorization to an iSNS server. Default is
disabled.
Note
iSNS Login Control cannot be used with
Access Control found on the iSCSI Target
Management page.
iSNSServer
Specifies whether the IP address of a valid iSNS server
from which the iPBridge will attempt iSCSI initiator
discovery. Setting to 0.0.0.0 disables the iSNS server
lookup. Default is 0.0.0.0.
SpeedWrite
When enabled, improves the performance of WRITE
commands to devices attached to the iPBridge.
CHAP commands
To find the CHAP commands,
1 Click on the Manual Target Mgt menu item.
2 Click on the Target Management page.
3 Click on the iSCSI CHAP table entry next to the
iSCSI target you wish to use.
iSCSI CHAP
iSCSI CHAP controls whether CHAP (Challenge
Handshake Authentication Protocol) is used for the iSCSI
protocol. If CHAP is enabled, the target requires the
initiator to negotiate CHAP authentication using CHAP
secrets (passwords). An initiator may reject this
negotiation.
iSCSI Chap Secret
Specifies the incoming and outgoing secrets (passwords)
for iSCSI CHAP sessions. Secrets are case sensitive, 12
to 32 characters (16 for Microsoft iSCSI initiator), and
cannot contain spaces. In and out secrets must be
different.
An in secret is for authentication of the server to the
iPBridge. The iPBridge can store up to 32 in secrets.
An out secret is for authentication of the iPBridge to the
server. There is only one out secret per target that cannot
be deleted.
iSCSITarget
Creates or deletes an iSCSI target name. The target
name acts as a suffix to the standard bridge iSCSIqualified name. The target name may not exceed 24
characters.

Set up a VLAN: Virtual Local Area Network
A Virtual LAN (VLAN) is a group of devices on the
same physical LAN which can communicate with each
other as if they were all on different physical LANs.
This creates a network that is independent of physical
location, allows grouping of users into logical
workgroups, increases efficient use of resources, and
adds security options by allowing some users into the
LAN and keeping other users out.
You may create up to eight Virtual LAN IDs for each
Ethernet data port. Each VLAN ID is assigned a VLAN
name of up to 64 characters. If no VLAN Id exists for a
data port, VLAN is disabled for that port.

4 Remote System Monitoring
You may set up the iPBridge to send notifications when certain events occur.
You may set up the iPBridge to send notifications
when certain events occur using the Remote
Management page of the ExpressNAV interface.
You designate the person receiving notification of
conditions and the level of severity which prompt
notification using the Simple Network Management
Protocol (SNMP) or Email notification.
For both methods, the severity level which is report
can be critical, warning or all.
• Critical means only critical event notifications
are sent.
• Warning means only warnings and critical event
notifications are sent.
• All means warnings, critical events and
informational messages are sent.
SNMP
An agent resides in the iPBridge which takes
information from the iPBridge and translates it into a
form compatible with SNMP. If certain conditions
arise, the agent sends notifications (traps) to a client.
Contact your network administrator for the MIB
software and appropriate MIB file for your iPBridge.

users when certain events occur with the iPBridge.
Serious error messages are sent immediately, while
messages for less serious errors are sent every 15
minutes.
You may send Emails to up to five Email addresses
and designate which conditions prompt each Email
notification.
For example, a recipient with a critical severity level
only receives critical messages and not warning or
informational messages.
When an event occurs that warrants Email notification,
the iPBridge sends the message; it cannot respond to
a rejection by a server for an invalid address. Ensure
all Email addresses typed in are valid.

6 Troubleshooting
If it is clear that a particular component system is at fault in a problem situation, go directly to that component. If
it is not clear, the best approach is to troubleshoot using the inside-out method.
You may check on the status of your iPBridge using
the ExpressNAV interface. Refer to Using
ExpressNAV on page 27. You may also look for
information by using the diagnostic CLI commands, in
the Advanced page of the ExpressNAV interface, or
by using the CLI directly (refer to CLI provides an
ASCII-based interface on page i of the Appendix.
Inside out method
To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first, then work
your way out:
• Fibre devices
• iPBridge Fibre ports
• iPBridge internal configuration
• iPBridge Ethernet/iSCSI ports
• LAN/WAN
• Ethernet host adapter or NIC in host
• Initiator
• OS
• Application
Check basic diagnostic tools
Check the host event log
Check the event log on the host. Look for the most
recent entries and determine what could be causing a
problem, then go to that event and continue
troubleshooting.
Check the event and trace logs
Check the iPBridge event log through the Advanced
page of the ExpressNAV interface or through CLI.
Look for the most recent entries and determine what
could be causing a problem. Then go to that event and
continue troubleshooting.
Visually inspect LEDs
If a non-fatal power supply problem occurs, or if a
problem is detected before shut down occurs, the
bicolor Ready/Fault LED flashes on the front and back
(connector) sides of the iPBridge 2700R/D and on the
front faceplate of the iPBridge 2700C. The Fault LED
also flashes briefly during start up. Off means not
ready, green on means ready, and yellow on means
faulted.
Inspect the iPBridge 2700C faceplate and iPBridge
2700R/D back (connector side) LEDs (see
Exhibit 6.0-1 and Exhibit 6.0-2):
• a lighted green LED, embedded in the connector
of the Ethernet management port, indicates a
valid link. Off shows that no link is present.
• a blinking yellow LED, embedded in the
connector of the Ethernet management port,
indicates activity.
• a bicolor LED, embedded in the connector on
each Gigabit Ethernet port, indicates 100/1000
Mb/sec. speed. Green on indicates 100 Mb/sec.
and yellow on indicates 1000 Mb/sec.
• a green LED for each Gigabit Ethernet port
indicates link/activity, where on solid indicates
link, blinking indicates activity and off is no link is
present.
• a green LED for each Fibre Channel port
indicates link where off means no link.
• a separate lighted green LED for each Fibre
Channel port shows activity and an unlit LED
means no activity.

Check Fibre Channel devices
Check iPBridge internal configuration
1
Verify that the Fibre Channel devices are mapped
properly using the ATTO ExpressNAV interface. If
devices do not appear, power down the iPBridge and
power back on. Refer to Using ExpressNAV on page
27 and Target Management on page 11.
When changing any setting on the iPBridge, the
configuration must be saved by clicking on the Save
button on the ATTO ExpressNAV interface screen or
using the saveConfiguration CLI command.
Check Fibre Channel device power. Make sure
the devices are powering up.
2 Watch the drive lights before, during, and after
startup.
3 Check cable integrity. Check the cables for
solid connections.
4 If the problem persists, try drives one at a time
with different cables, adding drives and cables
until the problem occurs. This helps pinpoint the
drive or cable causing the problem.
5 Check with the manufacturer of the device(s)
for further troubleshooting methods.
If Fibre Channel devices appear to be working order,
move on to the iPBridge Fibre Channel port section.
Check the iPBridge FC ports
1
Either through the ATTO ExpressNAV or CLI,
check the devices on each port.
If no devices appear, re-check cables. If
garbage information appears, the problem is
most likely a bad cable.
2 Check the internal cabling of the device.
3 If all devices appear, invoke the FCTargets
command several times on each port to verify
that the devices can be seen. If devices appear
and disappear, then appear again, the problem
is most likely a cable. For information on the
FCTargets command, refer to FCPortList on
page vii of the Appendix.
If all devices appear and remain, move to the iPBridge
internal configuration section.
When changing any setting on the iPBridge, the
configuration must be saved by clicking on the Save
button on the ATTO ExpressNAV interface screen
or using the saveConfiguration CLI command.
Check the serial port
1
Verify you have the correct settings and that
your terminal is configured to:
• Baud rate: 115200
• Data bits: 8
• Stop bits: 1
• Parity: off
Check iPBridge iSCSI ports

5
Check Ethernet cable integrity. Check the
cables for solid connections. Cat5 cable can
cause connection issues with Gigabit Ethernet.
Cat5E and Cat6 cable are the best cabling for
the iPBridge.
Verify the IP address, subnet mask, and
gateway are properly set on each data port on
the iPBridge for your network environment.
Refer to Using ExpressNAV on page 27.
Verify that the Ethernet speed is set to auto:
check the Ethernet page of the ATTO
ExpressNAV interface, or check the LED link
lights to determine if the Ethernet speed is
correct. Refer to Visually inspect LEDs on page
20.
Determine if the iPBridge is set to get its IP
information from a DHCP server. If so, verify
that the DHCP server has available IP
addresses.
Verify that each used Ethernet port on the
iPBridge can be pinged from the desired host.
Refer to Ping on page x of the Appendix.
If the host cannot ping the iPBridge ports and
the iPBridge ports are properly configured,
continue to the Local Area Network/Wide Area
Network section, Check the LAN/WAN on page
23.
Verify that each port on the iPBridge can ping
each desired host. Refer to Ping on page x of
the Appendix. If the iPBridge cannot ping the
host, continue to Check the LAN/WAN on page
23.
22
6
If using DHCP (the default), verify that the
DHCP server is assigning the correct IP
information to the host.
7 Verify VLAN IDs are either disabled or are set
up identically on the iPBridge and the
connecting switch.
8 Some older switches/hosts cannot auto
negotiate between the iPBridge and the
switch/host at the desired speed. You may
have to force the host/switch or the iPBridge to
the desired speed.
9 Verify that the host is logging into the iPBridge
correctly by viewing the Connections page
and determining if there a “session open”
status.
10 Verify that you are using the correct login
procedure for your initiator. For example: When
connecting using the Adaptec initiator, the log
on screen requests the iPBridge iqn (iSCSI
qualified name). If left blank, Adaptec will not be
able to log in. Enter “iSCSI” into this field for
auto iqn discovery.
When changing any setting on the iPBridge, the
configuration must be saved by clicking on the Save
button on the ATTO ExpressNAV interface screen or
using the saveConfiguration CLI command.
Check the LAN/WAN
1
2
3
Verify that the switch/switches are segmented
properly so that hosts and the iPBridge have
access to each other.
If there are routers involved in the setup, make
sure the IP addresses and/or MAC addresses
of the iPBridge are allowed through the router.
Verify that the switch can see the iPBridge on
the port(s) in question. Refer to your switch
vendor’s guide for more information.
Check the iSCSI Host Adapter or NIC
iSCSI host adapters appear as a type of Storage
Controller to the host OS, not as a standard NIC.
These adapters usually have hardware acceleration to
offload the TCP processing from the host.
Configuration of these adapters is usually done
through the vendor’s own utility and not through the
OS itself.
NICs come in two types: accelerated and unaccelerated. Accelerated NICs use some hardware to
offload some of the TCP processing from the host. Unaccelerated NICs make the OS do all TCP processing.
To check the iSCSI host adapter or NIC:
23
ATTO Technology Inc. iPBridge Installation and Operation Manual
1
Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.
2 Verify that the iSCSI host adapter or NIC is
configured with the correct IP information.
3 If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
4 Verify that the hosts are running the
recommended driver and firmware level for the
iSCSI host adapter or NIC vendor.
5 Verify that the hosts and the iPBridge Ethernet
port in use are using the same port number to
communicate iSCSI. Check the ATTO
ExpressNAV iSCSI page. The default port
number for all ports on the iPBridge is 3260.
6 Make sure the host adapter/NIC is configured
to log into the iPBridge. Some iSCSI host
adapters do not re-login upon reboot or
unplug/replug event without marking a check
box.
7 Some older switches cannot autonegotiate
between the host and the switch properly. You
could have to force the host or switch to the
desired speed.
For a NIC using an OS iSCSI driver, continue to the
iSCSI OS driver section.
Check the iSCSI OS driver
If the host uses a driver that allows the OS to talk to
iSCSI targets via a NIC, not an iSCSI storage adapter:
1 A PC using an iSCSI storage adapter and an
iSCSI OS driver might not work correctly on the
same machine. Check with the vendors to
make sure they are compatible.
2 Verify that the PC has the latest iSCSI driver as
well as the required service packs and patches.
Check with the iSCSI OS driver vendor for more
information.
3 Verify that the iSCSI OS driver has started.
Look under Device Manager for Windows or
lsmod for Linux.
4 Verify that the iSCSI OS is still looking for the
iPBridge at the right IP address.
5 If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
6 Verify that the NIC is configured with the correct
IP information.
7 Verify that the hosts and the iPBridge are using
the same port number to communicate iSCSI
8
on the ATTO ExpressNAV iSCSI page. The
default port number for the iPBridge is 3260.
Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.
3
Check the applications
1
Check the Operating System
1
2
Verify that the OS has the required service
packs or patches installed. If not, obtain the
proper service packs and patches and install
them.
Some iSCSI host adapters and iSCSI OS
drivers do not always automatically find new
targets when plugged in or when forced to
rescan. Reboot the hosts.
Check if the vendor has a new driver. If so,
install it.
2
Verify that the application is running the latest
device drivers for the devices connected to
iPBridge. If not, get the latest device drivers and
install them.
Verify with the application vendor if the iSCSI
technology is supported on the version of the
application being used.
Performance Issues
If the host is not getting the performance it should,
check the following items.
Check Fibre Channel devices
IP SAN traffic should be segmented so that it
does not interfere with the main LAN network
traffic.For better performance, the IP SAN
should be on its own set of hardware.
Verify that packets are not being dropped along
the LAN/WAN. Many utilities track packet
activity and switch statistics.
Verify that the devices are running at their highest
possible speed. Refer to FCDataRate on page vii of
the Appendix.
3
Check the iPBridge Ethernet ports
Check the Ethernet host adapter or NIC
1
2
3
Verify that the data port is set to auto negotiate
or forced to 1000 Mb/sec. on the ExpressNAV
Ethernet page.
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment. 9k frame size is
the current optimized frame size for the
iPBridge.
Verify that the iPBridge TraceLog feature is
disabled. Tracelog tracks certain events that
occur in the iPBridge. With this log enabled,
performance suffers. Refer to TraceLog on
page xii of the Appendix.
Ethernet storage adapters generally outperform
accelerated NICs and un-accelerated NICs by
offloading most of the processing from the host.
An accelerated NIC provides some offloading, but still
requires a host OS iSCSI driver, making the host
spend more CPU cycles.
An un-accelerated NIC does not offload anything so
the CPU must do much of the processing.
1 Verify that the adapter or NIC is sent to autonegotiate or forced to 1000 Mbs.
2 Set the MTU size to the largest MTU size
supported in the LAN/WAN using the Ethernet
page in the ATTO ExpressNAV interface.
Check the LAN/WAN
1
2
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment on the ATTO
ExpressNAV Ethernet page.
9k frame size is the current optimized frame
size for the iPBridge. Many switch and router
vendors do not support the larger frame size of
9k.
Verify that each associated port in the IP SAN
is configured for 1000Mbs.
3
9k frame size is the current optimized frame
size for the iPBridge. Many switch and router
vendors do not support the larger frame size of
9k.
Set the maximum transfer size to the most
efficient size for the intended target(s). For
many tape drives, 64k is the optimal setting.
Check applications
Some applications can be configured to change
transfer sizes. Configure the application for the optimal
24
size for the particular device(s) connected to the
iPBridge.
Check the host system
The faster the host, the faster your transfer times will
be. The work flow goes only as fast as the slowest
connection in the host system, so transferring data
from an IDE drive, 100Mb connection, a DLT 4000, a
high speed RAID volume across the country, or other
applications, slows the system no matter how fast
everything else is in the system.
1 Verify that the iSCSI storage adapter or NIC is
connected to the fastest PCI bus connector
supported by the adapter or NIC.
If the adapter supports PCI-X, place the
adapter in a PCI-X slot. If one is not available,
the host might not achieve the optimal
performance capable from the adapter.
2
Even placing a PCI-X adapter into a 64 bit 66
MHz slot loses performance. Some adapters
adjust clock speed depending on the speed of
the PCI slot into which they are plugged.
The host OS disk and swap disk/partition/file
should be on a high speed drive to minimize the
time needed to access the host’s virtual
memory.
The more memory a system has, the less time
it spends accessing virtual memory (hard drive
space).
Check the Operating System
If possible, eliminate swap space and virtual drives
which require large amounts of system memory.
However, the OS might not allow the elimination of
swap space. An OS set to run many kinds of different
servers spends much of its CPU cycles on other
operations, thus slowing down performance.

7 Interface Options
Alternative methods to the ATTO ExpressNAV interface may be used to manage the iPBridge. ATTO
ExpressNAV is the recommended interface.
Using ExpressNAV
Each page in the ATTO ExpressNAV interface
provides information and/or configuration parameters
based on a specific topic.
ATTO ExpressNAV is the recommended
management tool for the iPBridge. It is a web-based
graphical user interface (GUI) that allows you to
manage the iPBridge by clicking choices and
commands in traditional GUI fashion or by entering
CLI commands directly, as you would in a terminal
emulation session, on the Advanced CLI page.
Opening an ExpressNAV session
1
2
3
Point your browser at the IP address of the
iPBridge. Refer to Discovering the IP address
on page 7.
The ExpressNAV home page is displayed.
Click Enter.
Enter the user name and password values.
Note
The default values are user name: root and
password: Password. The user name is case
insensitive and password is case sensitive. It
is best practice to change user names and
passwords. Refer to Modify passwords on
page 15.
The Status page appears.
Each page can be reached through the menu at the
side of each page. An image on each page’s header
shows each port in the product faceplate. Each port is
clickable and takes you to the appropriate page.
If you have completed configuration operations at any
time and have clicked Submit on the page you are
viewing, go to the Restart page and restart the
iPBridge to save the settings.
If you have not completed configuration changes, go
on to the next command.

f. Click OK.
After you connect to the iPBridge, start-up
messages are displayed. These messages are
only displayed at start-up. The last line in the
start-up message sequence is Ready.
In serial port sessions, there is no prompt on
the line below the word Ready. Begin typing
commands in the blank line where the cursor is
resting. No user name or password is required
for serial port access.
6 To verify that you have connected successfully,
type help after the Ready prompt and press
Enter.
• If a list of all available commands does not
appear on the screen, review the steps in this
section, check the cable, or contact service
personnel until the problem is solved.
If you have difficulty using the serial port, verify that
you have the correct settings and that your serial cable
is less then two meters in length.
Using Telnet
Up to three Telnet sessions can be conducted
simultaneously. A serial port session can use the CLI
while Telnet sessions are open. Whichever session
issues the first set CLI command can continue to
issue set commands, while the other sessions can
only issue get commands or display information.
Once a connection is established, refer to CLI
provides an ASCII-based interface on page i of the
Appendix.
1 Connect to the iPBridge from a computer on the
same Ethernet network.
2 Start a Telnet session.
Note
There is more than one way to connect to the
iPBridge using a telnet program.Your telnet
program may operate differently than in the
following instructions.
3
At the telnet prompt, issue the open command
where x.x.x.x is the IP address of the iPBridge.
telnet > open x.x.x.x
4
If you have to specify a port type, enter the port
type “telnet” and the terminal type “vt100”.
port type: telnet
terminal type: vt100
5
Enter the default values for the user name,
root, and the password, Password, if you did
not set new values in Modify passwords on
page 15.
28
Appendix A CLI provides an ASCII-based interface
The command line interface (CLI) uses ASCII commands typed while in CLI mode.
•
CAUTION
Do not use CLI unless you are directed to
by an ATTO technician.
Changing parameters may cause loss of
data and/or disruption to performance and
reliability of the iPBridge.
The ExpressNAV interface is the preferred
method to operate and manage the
iPBridge. Refer to Using ExpressNAV on
page 27 for details.
The command line interface (CLI) is a set of ASCIIbased commands which perform configuration and
diagnostic tasks. Refer to Interface Options on page
27.
• CLI commands are context sensitive and
generally follow a standard format
•
[Get|Set] Command [Parameter1|Parameter2]
•
•
•
followed by the return or enter key
CLI commands are case insensitive: you may
type all upper or all lower case or a mixture.
Upper and lower case in this manual and the
help screen are for clarification only.
Commands generally have three types of
operation: get, set and immediate.
•
•
The get form returns the value of a parameter or
setting and is an informational command.
Responses to get commands are followed by
Ready.
The set form is an action that changes the value
of a parameter or configuration setting. It may
require a SaveConfiguration command and a
restart of the system before it is implemented.
The restart can be accomplished as part of the
SaveConfiguration command or by using a
separate FirmwareRestart command. A
number of set commands may be issued before
the SaveConfiguration command.
Responses to set commands are either an error
message or Ready. *. The asterisk indicates
you must use a SaveConfiguration command
to finalize the set command.
Set commands which do not require a
SaveConfiguration command, defined as
immediate commands, are immediately
executed.
Note
Using certain CLI commands during normal
operation can cause a performance drop.
Once command actions are complete,
performance should return to normal levels.
