To configure Layer 3 protocol filtering on Ethernet ports, perform this task in privileged mode:
Task
Step 1
Enable Layer 3 protocol filtering on the switch.
Step 2
Set the protocol membership of the desired ports. set port protocol mod/port {ip | ipx | group} {on
Step 3
Verify the port filtering configuration.
This example shows how to enable Layer 3 protocol filtering, set the protocol membership of ports, and
verify the configuration:
Console> (enable) set protocolfilter enable
Protocol filtering enabled on this switch.
Console> (enable) set port protocol 7/1-4 ip on
IP protocol set to on mode on ports 7/1-4.
Console> (enable) set port protocol 7/1-4 ipx off
