Concept Guide
• The maximum number of FIP snooping sessions supported per ENode server is 32 by default and the maximum number of sessions you
can congure is 64. To increase the maximum number of sessions to 64, use the fip-snooping max-sessions-per-enodemac
command.
• The maximum number of FCFs supported per FIP snooping-enabled VLAN is twelve.
• The maximum number of FCoE VLANs supported on the switch is eight.
• The maximum number of FIP snooping sessions (including NPIV sessions) supported per ENode server is 16
• Links to other FIP snooping bridges on a FIP snooping-enabled port (bridge-to-bridge links) are not supported on the switch.
• p-snooping port-mode fcf/fcoe-trusted CLI is not allowed on cascade, extended ports, or a LAG which contains these ports.
• p-snooping enable/p-snooping fc-map CLIs are not allowed on VLAN interfaces which has cascade or extended port as one of its
members either directly or indirectly via LAG.
Conguring FIP Snooping
You can enable FIP snooping globally on all FCoE VLANs on a switch or on an individual FCoE VLAN.
By default, FIP snooping is disabled.
To enable FCoE transit on the switch and congure the FCoE transit parameters on ports, follow these steps.
1 Congure FCoE.
To congure FCoE transit, refer to the FCoE Transit Conguration Example
NOTE: DCB/DCBx is enabled when either of these congurations is applied.
2 Save the conguration on the switch.
EXEC Privilege mode.
write memory
3 Reload the switch to enable the conguration.
EXEC Privilege mode.
reload
After the switch is reloaded, DCB/DCBx is enabled.
4 Enable the FCoE transit feature on a switch.
CONFIGURATION mode.
feature fip-snooping
5 Enable FIP snooping on all VLANs or on a specied VLAN.
CONFIGURATION mode or VLAN INTERFACE mode.
fip-snooping enable
6 Congure the port for bridge-to-FCF links.
INTERFACE mode or CONFIGURATION mode
fip-snooping port-mode fcf
NOTE
: To disable the FCoE transit feature or FIP snooping on VLANs, use the no version of a command; for example, no
feature fip-snooping or no fip-snooping enable.
