what is the PC Config process in the show cpu output?

Jump to solution

There are a few posts in the forum with people asking about the PC Config process/task in the sh proc cpu output, but no one has ever answered what that process is.

I've seen it jump up to 90% for short periods of time.

Would someone explain what this PC Config process/task is?

Thanks.

Roger,

The PCconfig thread contains quite a few tasks. Below I've pasted a list of some of the tasks that run in that thread.

Command line interface

Autolink

DNS

Http Client

Webserver

SNMP

Maintenence events for various interfaces (Ethernet, ADSL, SHDSL, DDS, etc.)

Fan Control

EFM (Ethernet in first mile)

NQM Network Quality Monitor

TopTalkers

OAM

Ping

Traceroute

DHCP

PPPoE

LLDP

Port Auth.

Bridging (Aging cache)

Clustering

GVRP

IGMP

VoIP Name Service

VQM (Voice Quality Monitoring)

Maintenence event for layer 2 (encap) protocols (PPP, FR, ATM)

Were you viewing the CPU in the web interface? Sometimes the web interface has a tendency to make the CPU spike for a short period.

Let us know if you have any questions..

Thanks,

Noor
