Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for a Four-FCC Multishelf System
The following example shows how to display information for the Spanning Tree Protocol (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.
Step 5 Use the show controller inter-rack stp command in administration EXEC mode, with the location
keyword, to verify the connection between the 22-port SCGE card. The active Cat6K goes into
forwarding state.
The location is the location of the 22-port SCGE card.
The following example shows location f0/sc0/cpu0:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp location f0/sc0/cpu0

Transferring the Backup Cisco Catalyst 65xx Switch Gigabit Ethernet
Connections to a Standby 22-port SCGE (Four-FCC Multishelf System)
To transfer the backup Cisco Catalyst 65xx switch GE connections to a standby 22-port SCGE 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.
