Reference Guide

NOTE: In FTOS Version 9.2.(0.0), content addressable memory (CAM) allocation is optional. If CAM is not
allocated, the following features are disabled:
– session monitoring
– aging
– class of service
You can enable iSCSI even when allocated with zero (0) CAM blocks. However, if no CAM blocks are
allocated, session monitoring is disabled and this information displays in the show iscsi command.
2. For a non-DCB environment: Enable iSCSI.
CONFIGURATION mode
iscsi enable
3. For a DCB environment: Configure iSCSI Optimization.
EXEC Privilege mode
iSCSI configuration: copy CONFIG_TEMPLATE/iSCSI_DCB_Config running-config.
The configuration files are stored in the flash memory in the CONFIG_TEMPLATE file.
NOTE: DCB/DCBx is enabled when you apply the iSCSI configuration in step 3. If you manually apply the iSCSI
configuration by following steps 1 and 2, enable link layer discovery protocol (LLDP) before enabling iSCSI in
step 2. You cannot disable LLDP if you enable iSCSI.
4. Save the configuration on the switch.
EXEC Privilege mode
write memory
5. Reload the switch.
EXEC Privilege mode
reload
After the switch is reloaded, DCB/ DCBx and iSCSI monitoring are enabled.
6. (Optional) Configure the iSCSI target ports and optionally the IP addresses on which iSCSI communication is
monitored.
CONFIGURATION mode
[no] iscsi target port tcp-port-1 [tcp-port-2...tcp-port-16] [ip-address
address]
– tcp-port-n is the TCP port number or a list of TCP port numbers on which the iSCSI target listens to
requests. You can configure up to 16 target TCP ports on the switch in one command or multiple
commands. The default is 860, 3260.
Separate port numbers with a comma. If multiple IP addresses are mapped to a single TCP port, use the no
iscsi target port
tcp-port-n command to remove all IP addresses assigned to the TCP
number.
To delete a specific IP address from the TCP port, use the no iscsi target port tcp-port-n
ip-address address command to specify the address to be deleted.
– ip-address specifies the IP address of the iSCSI target. When you enter the no form of the command,
and the TCP port you want to delete is one bound to a specific IP address, include the IP address value in
the command.
If multiple IP addresses are mapped to a single TCP port, use the no iscsi target port command
to remove all IP addresses assigned to the TCP port number.
To remove a single IP address from the TCP port, use the no iscsi target port ip-address
command.
