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
Transferring an Active Cat6K Gigabit Ethernet Connections to the Active 22-port
SCGE (Four-FCC Multishelf System)
To transfer an active Cat6K GE connections to the active 22-port SCGE and isolate the active Cat6K
from the control network, perform the following steps:
Step 1 Disable the active Cat6K port that is connected to the active RP on the DSC.
Step 2 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
the active RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding
(FWD) state. The location is the location of the active RP.
Step 3 Shut down the ports on the active Cat6K one at a time, with the exception of the four links between the
active Cat6K and the 22-port SCGE. Now, the active Cat6K remains connected to the fabric chassis with
four GE links.
Step 4 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding state.
Step 5 Move the disabled GE links from the RP to the active Cat6K to the 22-port SCGE. The following
locations are listed:
• 0/rp0-GE0 to F0/SC0-GE0
• 0/rp1-GE0 to F2/SC0-GE0
• 1/rp0-GE0 to F1/SC0-GE0
• 1/rp1-GE0 to F3/SC0-GE0
Step 6 Verify that all of the connections are bidirectional and have the correct neighbors by using the show
controller switch inter-rack udld command, with the all and location keywords, in administration
EXEC mode, as shown in the following syntax.
show controllers switch inter-rack udld {all location node-id}
Replace the node-id argument with the location of all of the 22-port SCGE card.
Step 7 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE0 port, which is connected to the 22-port SCGE, goes into the blocked (BLK) state.
Step 8 Raise the priority of the active Cat6K to 40960, which causes the root to change to the 22-port SCGE on
rack FCC0.
Step 9 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify that
the active SC on FCC0 is the new root switch.
Step 10 Shut down the port that is connected to active Cat6K to each of the 22-port SCGEs.
The migration is complete after you validate the new connections. You can remove the two
Cisco Catalyst 65xx switches.
