Chapter2 Catalyst 6500 Series Switch and ROM Monitor Commands set port protocol
set port protocol
To enable or disable protocol membership of ports, use the set port protocol command.
set port protocol mod/port {ip | ipx | group} {on | off | auto}
Syntax Description
Defaults The default is that the ports are configured to on for the IP protocol groups and auto for IPX and group
protocols.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines This command is not supported by the NAM.
Protocol filtering is supported only on nontrunking EtherChannel p orts. Trunking po rts a r e always
members of all the protocol groups.
If the port configuration is set to auto, the port initially does not receive any flood packets for that
protocol. When the corresponding protocol packets are received on tha t po rt, the su pervi so r eng ine
detects this and adds the port to the protocol group.
Ports configured as auto are removed from the protocol group if no packets are received for that protocol
within a certain period of time. This aging time is set to 60 minutes. They are also removed from the
protocol group on detection of a link down.
