Concept Guide

Impact Description
STP If you enable an STP protocol (STP, RSTP, PVSTP, or MSTP) on
the switch and ports enter a blocking state, when the state change
occurs, the corresponding port-based ACLs are 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 congure 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 congured on fanned-out ports or unusable 100G ports, trac outage occurs for about 45 seconds.
Conguring 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 congure the FCoE transit parameters on ports, follow these steps.
1 Congure FCoE.
FCoE conguration:
copy flash:/ CONFIG_TEMPLATE/ FCoE_DCB_Config running-config
The conguration les are stored in the ash memory in the CONFIG_TEMPLATE le.
NOTE
: DCB/DCBx is enabled when either of these congurations is applied.
2 Save the conguration on the switch.
EXEC Privilege mode.
write memory
3 Reload the switch to enable the conguration.
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 specied VLAN.
CONFIGURATION mode or VLAN INTERFACE mode.

6 Congure the port for bridge-to-FCF links.
INTERFACE mode or CONFIGURATION mode
