Ace 4710 can I capture packets on a Load Balancer

Richard Bradfield — Mon, 03 May 2010 23:51:18 GMT

We have just implemented JD Edwards we have three servers front ended by ACE4710,most things are good, but I there are some reports(.CSV)generated by the system that cannot be viewed when going through the load balancer, but ok if going directly to the server. I have logged on as a user that is getting the problem, and it is ok for me! So it looks as if it could be a PC problem, but other people think it must be the LB. is there anything like Tethereal available within the ACE that I could use to capture packets.

Hi,

There isn't a tethereal built-in to the ACE, but you can capture packets.

You need to create an ACL to identify the interesting traffic and then use the capture command. This is documented in the command reference guide.

When you stop the capture copy the file from flash to disk0: ('copy capture disk0:') The copying converts the capture into a pcap format file readable with any sniffer tool like wireshark. You'll need to download the file from disk0: to a workstation to be able to run wireshark against it.

HTH

Kind Regards
