apsMapChanNumber

Module: APS-MIB

OID (symbolic): APS-MIB::apsMapChanNumber

OID (numeric): 1.3.6.1.2.1.10.49.1.3.2.1.3

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 apsChanConfigIfIndex is set equal to an instance of ifIndex that has an ifType value of sonet(39), apsMapChanNumber is set equal to the corresponding value of apsChanConfigNumber.

If an instance of ifIndex that has an ifType value of sonet(39) ceases to be equal to an instance of apsChanConfigIfIndex, either because of a change in the value of apsChanConfigIfIndex, or because of row deletion in the ApsChanConfigTable, apsMapChanNumber is set to -1.

What is apsMapChanNumber?

Indicates the channel number assigned to a SONET interface within its APS group, where 0 is the null (protection) channel, 1-14 are working channels, and -1 means the interface is not part of any APS group.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.49.1.3.2.1.3
snmpwalk -v2c -c public <target> APS-MIB::apsMapChanNumber

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.49.1.3.2.1.3.1
