Table 30. Impact of Enabling FIP Snooping (continued)
Impact Description
deleted. If a port is enabled for FIP snooping in ENode or FCF
mode, the ENode/FCF MAC-based ACLs are deleted.
FIP Snooping Restrictions
The following restrictions apply when you configure FIP snooping.
● The maximum number of FCoE VLANs supported on the switch is eight.
● The maximum number of FIP snooping sessions supported per ENode server is 32. 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.
● When FCoE is configured on fanned-out ports or unusable 100G ports, traffic outage occurs for about 45 seconds.
Configuring 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 configure the FCoE transit parameters on ports, follow these steps.
1. Configure FCoE.
FCoE configuration:
copy flash:/ CONFIG_TEMPLATE/ FCoE_DCB_Config running-config
The configuration files are stored in the flash memory in the CONFIG_TEMPLATE file.
NOTE: DCB/DCBx is enabled when either of these configurations is applied.
2. Save the configuration on the switch.
EXEC Privilege mode.
write memory
3. Reload the switch to enable the configuration.
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 specified VLAN.
CONFIGURATION mode or VLAN INTERFACE mode.
fip-snooping enable
6. Configure 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.
