To delete an ML-Series card from the Cisco proprietary RPR, you need to complete several general
actions:
•
•

•
POS 0
SPR 1
POS 1
POS 0
Force away any existing non-ML-Series card circuits, such as DS-1, that use the spans that will be
deleted.
Shut down the POS ports on the adjacent ML-Series cards for the STS circuits 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 two STS circuits that will be replaced by the new circuits. (In
circuit between the Delete Node and one Adjacent Node, and the circuit between the Delete Node
and the other Adjacent Node.)
Remove the Delete Node from the ring topology if desired.
Physically remove the delete ML-Series card from the node if desired.
Create an STS circuit from the available POS port of one of the remaining adjacent ML-Series cards
to the available POS port on the other remaining adjacent ML-Series card. (In
the circuit between Adjacent Node 2, POS Port 0 and Adjacent Node 1, POS Port 1.)
Enable the POS ports on the existing adjacent ML-Series cards. (In
Adjacent Node 2, POS Port 0 and the Adjacent Node 1, POS Port 1.)
Test Ethernet connectivity between the access ports on the adjacent ML-Series card with a test set
to validate the two-node Cisco proprietary RPR.
Monitor Ethernet traffic and existing routing protocols for at least an hour after the node deletion.
