disruptions. Contact Cisco TAC at 1 800 553-2447 when prompted to do so in the procedure.
Perform this procedure during a maintenance window. Resetting the active TCC2/TCC2P can cause a
Note
service disruption of less then 50 ms to OC-N or DS-N traffic. Resetting the active TCC2/TCC2P can
cause a service disruption of 3 to 5 minutes on all Ethernet traffic due to spanning tree reconvergence if
any nodes in the Ethernet circuit are not using Software R4.0 or later.
Do not perform this procedure on a node with live traffic. Hot-swapping the AIP can affect traffic and
