ASR9K CPU usage

[Newbie_folks]

Hi

I have run the top command in ASR9K and I have observed that the top 2 causing high CPU utilization are sits and ifmgr.

Can anyone help me understand what are these two processes? and how can I reduce the CPU consumption.

388 processes; 2135 threads;
CPU states: 35.7% idle, 63.2% user, 1.0% kernel
Memory: 8192M total, 3970M avail, page size 4K
Time: Sat Mar 16 07:40:49.493 UTC

JID TID LAST_CPU PRI STATE HH:MM:SS CPU COMMAND
414 1 1 10 Run 1780:17:31 28.76% sits
247 1 0 10 Run 1725:24:51 27.96% ifmgr

Thanks!

top gives you the instantaneous CPU utilization, it is expected to be higher than show process cpu. I recommend checking show process cpu instead to look for high cpu consumers as one or two processes being high in top is not uncommon and does not necessarily indicate a problem.

To answer your question sits is Software Interface Transport Process and ifmgr is Interface Manager which has to do with the create/state change/mtu change and adding of features etc.
