XAMPLE
ALU(config)# interface GigabitEthernet 3/0
ALU(config-if GigabitEthernet3/0)# l2 filter in F1
If the filter F1 is interfaced to GigabitEthernet, the following command detaches it 
from the interface:
ALU(config)# interface GigabitEthernet 3/0
ALU(config-if GigabitEthernet3/0)# no l2 filter in F1
Command (in ICM) Description
l2 filter {in|out} <filter-
name>
This command is used to attach a L2 
filter to an interface in ‘in’ or ‘out’ 
direction.
Filter is applied to the ingress 
(incoming) traffic if  “in” keyword is 
used.
Filter is applied to the egress 
(outgoing) traffic if  “out” keyword is 
used.
no l2 filter {in|out} <filter-
name>
This command detaches a L2 filter 
attached to an interface.
This does not delete the filter definition 
in its entirety. It only detaches it from 
the interface it is attached to.
