I have problem with 6513 switch. All these days it worked fine with existing hardware,software and configuration.
Suddenly switch started hanging. It happened 2 times in 24 hours. Redundant links are removed, it is having single link to core switch. But then also it hanged.
After shutting down link between core and distribution switches, switch started functioning (link shutdown is done at core switch side).
And also If I run any command like
#sho run | in <xxx> , cpu utilization raising to 90%. Is it normal symptom.
I am suspecting that some process is causing high cpu utilization , due to that switch is hanging. But I dont understand the reason, when link is disconnected and reconnected it starts working.
Any helpful suggestions on this.
