rlCpuCountersTxMC
Module: CISCOSB-CPU-COUNTERS-MIB
OID (symbolic): CISCOSB-CPU-COUNTERS-MIB::rlCpuCountersTxMC
OID (numeric): 1.3.6.1.4.1.9.6.1.101.124.1.1.3

Description: Number of transmitted multicast packets.
What is rlCpuCountersTxMC?
This read-only Counter32 counts multicast packets transmitted by the device's CPU. An admin uses it to gauge how much multicast control or management traffic (such as routing protocol updates) the CPU is generating, which helps in diagnosing CPU load issues. For example, if this counter climbs rapidly while multicast routing is enabled, the admin can correlate it with CPU utilization spikes tied to multicast protocol activity.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.124.1.1.3 snmpwalk -v2c -c public <target> CISCOSB-CPU-COUNTERS-MIB::rlCpuCountersTxMC
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.124.1.1.3.1 snmpget -v2c -c public <target> CISCOSB-CPU-COUNTERS-MIB::rlCpuCountersTxMC.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> rlCpuCountersTxMC.1
