I heve C7609 with SUP720-3BXL in core of internet provider. There are full BGP from three uplinks, some BGP downlinks and a lot of clients' vlan. But in last two months I'v had problems- High CPU utilization.
The "sh processes cpu" says me main problems is:
Port manager per
HIDDEN VLAN Proc
Can you tell me please what do next tasks stand for and what else must I do?
"Check heaps,ARP Input,Port manager per, HIDDEN VLAN Proc, Virtual Exec"
With best regards...
