Operational Commands

FIP Snooping Configuration

1. Enable VLAN tagging on FCoE ports:
2. Place FCoE ports into a VLAN supported by the FCF and CNAs (typically VLAN
272
CN4093 Application Guide for N/OS 8.2
For example:
CN4093# show fcoe fips port ext4 information
FIP Snooping on port ext4:
This port has been detected to be an FCF port.
FIPS ACLs configured on this port:
Ethertype 0x8914, action permit.
dmac 00:00:18:01:00:XX, Ethertype 0x8914, action permit.
For each ACL, the required traffic criteria are listed, along with the action taken
(permit or deny) for matching traffic. ACLs are listed in order of precedence and
evaluated in the order shown.
The administrator can also view other FCoE information:
CN4093# show fcoe fips fcf
CN4093# show fcoe fips fcoe
The administrator may use the operational commands to delete FIP‐related entries
from the switch.
To delete a specific FCF entry and all associated ACLs from the switch, use the
following command:
CN4093# no fcoe fips fcf <FCF MAC address> [<VLAN number>]
In this example, as shown in Figure 31 on page
ENode, and EXT22 is connected to the Fibre Channel network via an internal FCF
(see"Fibre Channel" on page
using the following CLI commands:
CN4093(config)# interface port INTA1, EXT22(Select FCoE port)
CN4093(config­if)# switchport mode trunk(Enable VLAN tagging)
CN4093(config­if)# exit
1002):
CN4093(config)# vlan 1002
CN4093(config­vlan)# exit
CN4093(config)# interface port INTA1, EXT22
CN4093(config­if)# switchport trunk allowed vlan 1002
CN4093(config­if)# exit
Note: Placing ports into the VLAN
ensure that their port VLAN ID (PVID) is not accidentally changed.
