RE: WS-C3750X-48T-S CPU high !!!

1. You are pointing a static route to an interface or something it cannot arp.

2. You are running broadcast/multicast on vlan with an SVI and need to implement CoPP to protect the device.

Let us know which.

Dear Expert,

I have some problem with CPU utilization of WS-C3750X-48T-S
(C3750E-UNIVERSALK9NPE-M), Version 12.2(55)SE. My vendor already implement
many static route. Now it has no traffic utilization through it. Anybody
know this is bug of IOS or not?? I try to see process with "sh process cpu |
ex 0.00" but don't see some process take cpu.

3750#sh ip route sum
IP routing table name is Default-IP-Routing-Table(0)
IP routing table maximum-paths is 32
Route Source Networks Subnets Overhead Memory (bytes)
connected 1 4 320 760
static 5 516 33344 79192
internal 174 203928
Total 180 520 33664 283880
=============================================
