Chapter2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch Syst em for a Four-FCC Multishelf System
Step 2 Move the disabled GE links between RPs and the backup Cat6K to the newly inserted 22-port SCGE
cards. The following locations are listed:
•0/rp0-GE1 to F1/SC1-GE0
•0/rp1-GE1 to F3/SC1-GE0
•1/rp0-GE1 to F0/SC1-GE0
•1/rp1-GE1 to F2/SC1-GE0
Step 3 Use the show controllers switch inter-rack udld command in administration EXEC mode, with the all
and location keywords, to verify that all of the new connections are bidirec tional and have the correct
neighbors.
The location is the location of the 22-port SCGE card.
Step 4 Use the show controllers switch stp location command in administration EXEC mode to verify that 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 the active Cat6K are in the forwarding state.
Step 5 Verify that there is no impact to the active topology and the control Ethernet traffic because the active
Cat6K remains as the root.
Performing a Failover to a Standby 22-port SCGE (Four-FCC Multishelf System)To perform a failover to a standby 22-port SCGE and swap the remaining SCGE with the new 22-port
SCGEs, perform the following steps:
Step 1 Perform a failover to an FCC0, to the new 22-port SCGE. Use the following syntax for the redundancy
switchover command, with the location keyword, in EXEC mode:
redundancy switchover location node-id
Replace the node-id argument with the location of the active 2-ports SCGE ca rd.
Step 2 Verify that the failover is completed by using the show platform command and show redundancy
command.
The show platform command shows that the 22-port SCGE card is in IOS XR RUN state.
The show redundancy command shows that the 22-port SCGE card is in the active state.
Step 3 After the 22-port SCGE becomes active, swap the 2-ports SCGE (active SC) with the new 22-port SCGE
card.
Note Do not attempt this step before Step 2 has completed.
Step 4 Use the show platform command in EXEC mode or administration EXEC mode to verify that the newly
22-port SCGE is in the IOS XR RUN state.
Step 5 Use the show redundancy command in EXEC mode to verify that the newly inserted 22-port SCGE
cards are in standby ready.
Step 6 Repeat Step 1 to Step 4 for FCC1, FCC2, and FCC3.
