For administrative and troubleshooting purposes, flush the routing tables.
To flush tables on a VRF instance for a port or VLAN, ensure that the VRF is associated with the port or VLAN.
enable
configure terminal
interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}
Note
If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
