Note
Card protection does not take effect until you enable the ports on all the cards in the protection group.
Because ports must be enabled before the cards carry traffic, you can enable the ports immediately after
provisioning card protection, or wait until you are ready to send traffic on the cards.
Caution
Before running traffic on a card within a protection group, enable the ports of all protection group
cards.
Procedure: Enable Ports
Log into the node in CTC and display the card you want to enable in card view.
