CPU question.

What exactly is the "ip background" process when doing a show proc cpu. What exactly would that be related to if I were showing high cpu on that process.

Thanks in advance for any help.

Hello,

here is an explanation of that process:

>IP Background Process

Called upon when you change the encapsulation (for example, when an interface moves to a new state, an IP address changes, when you add a new Data Exchange Interface (DXI) map, or when some dialer timers expire)

Does the periodic aging of the Internet Control Message Protocol (ICMP) redirect cache.

Modifies the routing table according to the status of the interfaces.

Re: CPU question.

"IP background" is Periodically revises the gateway of last resort and IP static routes. This process is called on demand, right after the static routes (which the gateway of last resort may depend on) have been revised.
