FIP Snooping for Specific Ports

© Copyright Lenovo 2016
FCoE Initialization Protocol (FIP) snooping is an FCoE feature. To enforce
point‐to‐point links for FCoE traffic outside the regular Fibre Channel topology,
Ethernet ports used in FCoE can be automatically and dynamically configured
with Access Control Lists (ACLs).
Using FIP snooping, the G8264 examines the FIP frames normally exchanged
between the FCF and ENodes to determine information about connected FCoE
devices. This information is used to create narrowly tailored ACLs that permit
expected FCoE traffic to and from confirmed Fibre Channel nodes, and deny all
other undesirable FCoE or FIP traffic.
In case of LAGs, FIP traffic from a particular FCF can be received by any member
port on which the FCF was detected.
By default, the FIP snooping feature is turned off for the G8264. The following
commands are used to turn the feature on or off:
RS G8264(config)# [no] fcoe fips enable
Note: FIP snooping requires CEE to be turned on (see "Turning CEE On or Off" on
page 368).
When FIP snooping is on, port participation may be configured on a port‐by‐port
basis (see the next sections).
When FIP snooping is off, all FCoE‐related ACLs generated by the feature are
removed from all switch ports.
FIP snooping configuration must be the same on all member ports in a LAG. If the
configuration of a member port is changed, an error message, similar to the
following, will be displayed.
"FAIL: Trunk X FIP Snooping port Yand port Z need to have the same fcf
mode config"
The configuration changes are applied to all member ports in a LAG.
When FIP snooping is globally turned on (see the previous section), ports may be
individually configured for participation in FIP snooping and automatic ACL
generation. By default, FIP snooping is enabled for each port. To change the setting
for any specific port, use the following CLI commands:
RS G8264(config)# [no] fcoe fips port <port alias, number, list, or range> enable
