Transferring an Active Cat6K Gigabit Ethernet Connections to the Active 22-port
SCGE (Single-FCC Multishelf and Two-FCC Multishelf Systems)
To transfer the 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 links that are connected to the active RP on the Designated Shelf Controller
(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 an
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 (FWD)
state.
Step 5 Move the disabled GE link connecting the RPs and the active Cat6K link to the 22-port SCGE card.
Step 6 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 7 Raise the priority of active Cat6K to 40960, which causes the root to change to 22-port SCGE on rack
FCC0.
Step 8 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 9 Shut down the port that is connected to the active Cat6K on each of the 22-port SCGEs.
Step 10 Verify that there is no impact to the active topology and the control Ethernet traffic.
The migration is complete after you validate the new connections. You can remove the two
Cisco Catalyst 65xx switches.
