cntifCpu
Module: CNTAU-MIB
OID (symbolic): CNTAU-MIB::cntifCpu
OID (numeric): 1.3.6.1.4.1.333.1.2.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The cpu number where the device driver for this interface resides.
What is cntifCpu?
This read-only INTEGER reports the CPU number (lcp-1 through lcp-7) where the device driver for this interface resides. An admin troubleshooting a misbehaving interface would use this to know which specific processor's health and load could be affecting that interface's performance. For example, an interface exhibiting drops that reside on a CPU also showing high utilization would suggest the CPU, not the interface hardware itself, is the bottleneck.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.1.2.1.1.3 snmpwalk -v2c -c public <target> CNTAU-MIB::cntifCpu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.333.1.2.1.1.3.1 snmpget -v2c -c public <target> CNTAU-MIB::cntifCpu.1
