Optimized FCoE Traffic Flow

G8264CS Application Guide for ENOS 8.4

To optimize FCoE traffic flow between FCoE enodes, the optimized‐forwarding

feature installs appropriate ACL entries for logged‐in nodes. Most of the time,

FC/FCoE traffic in full‐fabric mode needs to go through an FC module for Zone

checking. You can achieve low latency if the Zone check is done on Ethernet switch

module for FCoE‐FCoE traffic. The optimized‐forwarding feature is enabled by

default in full‐fabric mode but is not applicable to NPV mode.

Note: FCoE‐FC and FC‐FC traffic is not optimized.

If needed, you can disable optimized‐forwarding feature. Before you do, you must

disable FIP snooping. Use the following commands:

RS 8264CS(config)# no fcoe fips enable

RS 8264CS(config)# no fcoe optimized-forwarding enable

To re‐enable optimized‐forwarding feature, use the following command sequence:

RS 8264CS(config)# no fcoe fips enable

RS 8264CS(config)# fcoe optimized-forwarding enable

RS 8264CS(config)# fcoe fips enable

To view optimized traffic flow information, use the following commands:

RS 8264CS(config)# show fcoe optimized-forwarding status

RS 8264CS(config)# show fcoe optimized-acls vlan <vlan ID>
