Chapter2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for Single-FCC Multishelf and
Two-FCC Multishelf Systems
Replace the interface number argument with the port that is connected to the active Cat6k.
Replace the node-id argument with the newly inserted standby 22-port SCGE card .
The following example sample output displays information for STP from the show controllers switch
inter-rack stp command:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp ports 0 location
GE_0 of MST1 is designated forwarding
Edge port: no (default) port guard : none (default)
Link type: point-to-point (auto) bpdu filter: disable (default)
Boundary : internal bpdu guard : disable (default)

For the 22-port SCGE ports which are connected to each other, one is in the forwarding state and the
other is in the blocked state.
Transferring the Backup Cisco Catalyst 65xx Switch Gigabit Ethernet Connections to a Standby 22-port SCGE (Single-FCC Multishelf and Two-FCC Multishelf Systems)To transfer the backup CiscoCatalyst 65xx switch GE connections to a standby 22-port SCGE card and
to isolate the backup Cisco Catalyst 65xx switch from the control network, perform the following steps:
Step 1 Shut down the ports on the backup Cat6K one at a time. Make the interCat6K port the last port to shut
down.
Step 2 Move the disabled GE connections between the active RPs (on both the LCC in case of a 2 FCC MC)
and the backup Cat6K to the standby 22-port SCGE.
Step 3 Use the show controllers switch stp command, with the location keyword, in administration EXEC
mode, to verify that the RP ports (GE1) that are connected to the 22-port SCGE are in the blocked state,
and that the RP ports (GE0) that are connected to an active Cat6K are in the forwarding state, as shown
in the following syntax:
show controllers switch inter-rack stp location node-id
Replace the node-id argument with the location of the 22-port SCGE card. In addition, you can use the
newly inserted standby 22-port SCGE card.
