All,
Anyone seen any odd CPU utilization with NTP on SXI4? For what it's
worth, it's a VSS pair, been up several months. Added the NTP config a few
weeks ago, didn't see CPU issue until last couple days. It's doing md5
authentication, 2 servers, and 1 peer. It also serves NTP to a couple dozen
devices currently. CPU due to NTP is about 40%, CLI is sluggish. As a test
to verify it was a client killing it, I setup control plane policing, 32000
bps. Not seeing anything exceeding that, in fact only about 50 packets per
minute are coming into the box. Yet the CPU stays high. Blowing away NTP
sends CPU back down to 0, but adding config back in raises it again.
Removing authentication didn't help either. No bugs found on CCO about it.
Any ideas?Config: ntp authentication-key 1 md5 082F585E4412000E435B 7 ntp authenticate ntp trusted-key 1 ntp clock-period 17179684 ntp update-calendar ntp peer vrf USSOUTH 10.4.0.97 key 1 ntp server vrf USSOUTH 130.22.32.2 key 1 ntp server vrf USSOUTH 130.22.32.3 key 1 Thanks, Chuck
