Strange issue with ACE capture command

silk
Level 1
Level 1

Hello there,

I have one load balancer (ACE A2 3.6a) that is acting weird on simple capture traces.

setting up an access-list:

access-list test extended permit ip any host 10.10.10.1

gives the following unusual output:

15:38:53.956439 0:c:9:b8:0:0 0:55:0:50:80:34 0088 9404: sap 04 > sap 00 I (s=0,r=40,C) len=9386

                         0a25 bd68 6402 01bb f064 0cbf b229

instead of the classic tcpdump like output showing ip addresses.

What could possibly be wrong?

Hi, it's CSCtz75479 which is regression and affects only A236 and A236a.

I have a similar problem.  If I take a pcap and view it via the ACE CLI I am able to see the L3 information.  However when I copy the file to my workstation and open with Wireshark I only see the L2 information. 

In my case nothing changes.

If I import the captured file into wireshark I still don't get IP information, just the same garbage that I can see

in realtime in the CLI.

Hi Borys,

thanks for yout reply.

Bug description states that it's fixed in:

3.0(0)A2(3.6b),3.0(0)A2(3.5.96)

but none is available for download.

Where can I get a non affected up-to-date version of the ACSW for the ACE Module?

Thanks in advance.
