Specifying An Rlir Preferred Host - Cisco MDS 9000 Series Configuration Manual

Specifying an RLIR Preferred Host

The RLIR data is written to persistent storage when you enter the copy running-config startup-config
command.
The RLIR data is written to persistent storage when you copy the running configuration to the startup
configuration.
Specifying an RLIR Preferred Host
As of Cisco MDS SAN-OS Release 3.0(3), you can specify a preferred host to receive RLIR frames. The
MDS switch sends RLIR frames to the preferred host only if it meets the following conditions:
• No host in the VSAN is registered for RLIR with the registration function set to "always receive." If one
• The preferred host is registered with the registration function set to "conditionally receive."
Note If all registered hosts have the registration function set to "conditionally receive," then the preferred host
receives the RLIR frames.
You can specify only one RLIR preferred host per VSAN. By default, the switch sends RLIR frames to one
of the hosts in the VSAN with the register function set to "conditionally receive" if no hosts have the register
function set to "always receive."
To specify the RLIR preferred host for a VSAN, follow these steps:
Step 1
switch# config terminal
switch(config)#
Enters configuration mode.
Step 2 switch(config)# rlir preferred-cond fcid 0x772c00 vsan 5
Specifies FC ID 0x772c00 as the RLIR preferred host in VSAN 5. (FC ID 0x772c00 is used here as an example.)
Step 3
switch(config)# no rlir preferred-cond fcid 0x654321 vsan 2
(Optional) Removes FC ID 0x772c00 as the RLIR preferred host for VSAN 5.
To display the RLIR preferred host configuration, use the show rlir erl command.
switch# show rlir erl

or more hosts in the VSAN are registered as "always receive," then RLIR sends only to these hosts and
not to the configured preferred host.
