ACL capture on Nexus 7K

Hi ,

I am trying to setup an ACL capture on Nexus 7K as we need to have more than 2 span sessions.

The capture is working however the wireshark traces only show the L2 information and not the L3 header.

Has anybody come across this issue and has any idea.

I am attaching the config that I am doing and also the wireshark pcap file

Any help would be appreciated.

Regards,

Imran.

HI Imran,

I see that protocol is unknown in those packet - 0xf000. Can you please try some other L3 traffic through this VLAn and see if that also decoded with unknown protocol type instead of 0x8000 for ip.

Hi Nikolay,

I've tried http/telnet traffic but it yields the same results. I am not sure whats going on.

Hi,

Can you pls paste "show ver", "show ip access-lists capture session 1", "show running-config aclmgr" and  "show int vlan3".
