no, off, false, disabled The port forwards all
unknown egress unicast
frames. This is the
default. These options
are equivalent.
Description
This command discards ingress and egress broadcast packets as well as
unknown unicast and multicast packets on a port. When you activate this
feature on a port, the port discards all ingress or egress packets of the
type specified. The default setting for each type of packet filter is disabled.
Examples
This command activates the ingress broadcast filter on ports 2.4 and 2.23
The ports discard all ingress broadcast packets:
set switch port=2.4,2.23 bcastfiltering=yes
This command activates the unknown egress multicast and unicast filters
on ports 3.3 and 3.6, causing the ports to discard all unknown egress
multicast and unicast packets:
set switch port=3.3,3.6 unkmcastegressfiltering=yes
unkucastegressfiltering=yes
This command disables the unknown ingress unicast filter on port 2.24 so
that the port again accepts all unknown ingress unicast packets:
set switch port=2.24 unkucastfiltering=no
