cntPortNum
Module: CISCO-WAN-AXIPOP-MIB
OID (symbolic): CISCO-WAN-AXIPOP-MIB::cntPortNum
OID (numeric): 1.3.6.1.4.1.351.110.5.1.1.2.1.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Refers to the logical port index For FRSM12 card: The ifIndex of the port's corresponding row in ifTable. Byte 3 = Chassis Number, Byte 2 = Slot Number, Byte 1 & 0 = Encoded unique number for Port.
What is cntPortNum?
This read-only integer is the logical port index for a port-level traffic counter row; on FRSM12 it is the ifIndex of the port's corresponding row in ifTable, encoded with chassis number, slot number, and port number in separate bytes. An administrator reads this to identify which specific logical port a given set of port-level counters (rcvPortFrames, rcvPortBytes, and related objects) belongs to. For example, on an FRSM12 card, decoding cntPortNum's byte layout would reveal the specific chassis, slot, and port whose traffic counters that row is reporting.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.351.110.5.1.1.2.1.1.1.1 snmpwalk -v2c -c public <target> CISCO-WAN-AXIPOP-MIB::cntPortNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.351.110.5.1.1.2.1.1.1.1.1 snmpget -v2c -c public <target> CISCO-WAN-AXIPOP-MIB::cntPortNum.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cntPortNum.1
