Description: Refer to the description for igPrimaryEocTmcDs1IfIndex.

This object refers to the ifIndex for the DS1 line supporting the standy EOC and TMC path protection switching. The value for this object is equal to the value of ifIndex from the Interfaces table of MIB II (RFC 1213).

The value will be zero if the Interface Group is not installed on a specific card or no secondary DS1 is provisioned.

What is igSecondaryEocTmcDs1IfIndex?

Reports the ifIndex of the DS1 line carrying this Interface Group's standby EOC/TMC signaling path, or zero if the IG isn't installed on a card or no secondary DS1 is provisioned. Admins check this alongside igPrimaryEocTmcDs1IfIndex to confirm the protection path is provisioned on a genuinely separate DS1.
