To add an ML-Series card to the Cisco proprietary RPR, you need to complete several general actions:
Force away any existing non-ML-Series card circuits, such as DS-1, that use the span that will be
•
deleted.
Shut down the POS ports on the adjacent ML-Series cards for the STS circuit that will be deleted to
•
initiate the Cisco proprietary RPR wrap.
Test Ethernet connectivity between the access ports on the existing adjacent ML-Series cards with
•
a test set to ensure that the Cisco proprietary RPR wrapped successfully.
Delete the STS circuit that will be replaced by the new circuits. (In
•
between Adjacent Node 2, POS 0 and Adjacent Node 1, POS 1.)
• Insert the new node into the ring topology if the node is not already part of the topology.
Install the ML-Series card and load your initial configuration file or otherwise do an initial
•
configuration of the ML-Series card.
• Ensure the new node is configured with Cisco proprietary RPR before its POS ports are manually
enabled or enabled through the configuration file.
Create an STS circuit from one of the POS ports of an existing adjacent ML-Series card to a POS
•
port on the new ML-Series card. (In
POS Port 0 and New Node, POS Port 1.)
Create a second STS circuit from one of the POS ports of the other existing adjacent ML-Series card
•
to the remaining POS port on the new ML-Series card. (In
New Node, POS Port 0 and Adjacent Node 1, POS Port 1.)
Configure the new ML-Series card to join the Cisco proprietary RPR and enable the POS ports, if
•
the initial configuration file did not already do this.
Enable the POS ports on the existing adjacent ML-Series cards that connect to the new ML-Series
•
card. (In
