cApsMapChanNumber
Module: CISCO-APS-MIB
OID (symbolic): CISCO-APS-MIB::cApsMapChanNumber
OID (numeric): 1.3.6.1.4.1.9.10.71.1.3.2.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This field is set to a unique channel number within an APS group. The value 0 indicates the null channel. The values 1-14 define a working channel. If the SONET LTE is not part of an APS group this value is set to -1.
When an instance of cApsChanConfigIfIndex is set equal to an instance of cApsMapIfIndex, cApsMapChanNumber is set equal to the corresponding value of cApsChanConfigNumber.
If the cApsMapIfIndex ceases to be equal to an instance of cApsChanConfigIfIndex, either because of a change in the value of cApsChanConfigIfIndex, or because of row deletion in the CApsChanConfigTable, cApsMapChanNumber is set to -1.
What is cApsMapChanNumber?
This read-only field reports the channel number this interface holds within its APS group (if any) -- 0 meaning it's specifically the null/protection channel, 1 through 14 identifying it as one of up to 14 working channels, and the special value -1 meaning this SONET LTE interface isn't part of any APS group at all. Together with cApsMapGroupName, this lets an admin fully identify an interface's exact role in its protection scheme starting from nothing but its ifIndex. For example, an interface reporting a channel number of 0 alongside a valid group name is specifically the protection line for that group, while a -1 here regardless of what cApsMapGroupName shows confirms the interface has no APS role at all.
