We have Cisco ACE used in our company and yesterday, we had add new servers to loadbalancer (which have teaming configured Active/Active) and after maybe 3 hours of implmentation our network became unstable since we had disconnection and connection again on different VLANs and we noticed that arp_mrg have consumed about 98 % of cpu process.
So, my questions are:
1- Does arp_mgr cause such impact of unstability? and what to do to reduce this process if we see it again?
2- do you know a tool can monitor cisco ACE CPU and error logs and warning ?
It sounds like the type of teaming you are doing is the problem. The ACE does not play well with Active Active teaming. You should configure your NICs to use an Active/Standby configuration so the ACE will only see a single MAC address for this rserver.
So, as result of this teaming and high CPU utilize, am I expecting unstability of ACE connected VLANs ? because it was stable for some time then started to be unstable for all connected VLAN. However, I do believe this might be the issue but I need to find out some information or logs in ACE proves this assumption to support this case.
Also, I am looking to find tool or a way to monitor ACE errors and warning messages and maintain them
