high cpu on 6500

Hello,

CPU is high due to interrupts (traffic) and it is good you have taken nedtr capture.

Ethertype 6002 is MOP for incoming packets

1. It looks like your router may transmit DECnet MOP (DEC Maintenance Operation Protocol (MOP)) packets (ethertype 6002) to multicast

MAC address ab00.0002.0000

2. Those packets sourced from Vlan 10(MAC 0023.33C5.AD80) were massively punted to CPU -

a part of netdrive capture below:

3.You can jcheck if  MOP protocol and MOP sysid enabled on on Vlan4005 or inout interfaces Gi1/1 and Gi1/3 and consider if you want to remove.

4. You can also trace the source MAcs of coming packets and understand why MOP traffic is coming from it.

Hope this helps,

Hi,

thank you for your answer.

I have disable mop on vlan interfaces, but still same.

how can i completely disabe mop?

Hey.

Did you check it on physical interfaces as well? It might be needed to be disabled there. Also you can see where those source MAcs 00.21.D8.B2.2B.00 and 00.14.1B.30.50.00 are coming from. I do see these two sending MOP packets.

check where those are learnt from with "show mac-addr addr 0014.1B30.5000" or similar (based on platform) command and go to the device connected on that interface to do same check until you find the end host with that MAC.

Hope that helps.

high cpu on 6500

hi,

i have diasble mop on physical interfaces also.  g1/1 ang g1/3 are also 6500. I have disable mop on their phsical and vlan interfaces but netdr output still shows ether 6002..  can i police these packets via COPP?

Cisco Employee

high cpu on 6500

I guess CoPP wont help here as ethertype 6002 is not ip so IP acl wont help and Copp afaik does not support MAC acl.

You can try to create MAC ACL or VACL and apply that on port just to drop those MAC addresses as sources.

I guess now even with MOP disabled switch treat destination MAC of those packets like some mcast MAC and send copy ofr CPU analysis.
