Issues with ACE after upgrading software

kalugotla1 — Wed, 14 Sep 2011 02:02:59 GMT

In the lab we upgraded our ACE4710 to A4(2.1a) version.After giving the command boot system image to the new version ,reload ACE.

After reload It still had the old image

but the network in the lab was really slow ,and all the servers had intermittent slowness issue ,so after unpluging the ACEs from the network ,everything seemed working perfectly fine.

So not sure what caused this issue ,checked the config through the console ,and it is very basic and simple configuration ,and when I did sh ver ,was able to see the latest version.

Experts please advise me on this.

The image you are running on the ACE is not the old image. It's A4_2_1a per sh ver.

I guess the issue you are trying to resolve is slowness via ACE after the upgrade. If this is a right understanding of the problem, then please provide a following info :

1. Can you verify if this problem happens only after the SW upgrade to A4_2_1a ?

2. When you said the network in the lab was really slow, how did you monitor the slowness? Can you give us more detaled observation?

3. Can you give us more info about the ACE deployment in your lab along with config?

regards

Andrew

with the old config on ACE ,i was able to ping the device and also had remote access to it.After reloading the new image ,The device was not pingable ,(and also was not able to telnet into it).

We had issues reported from serveral dev server teams ,that they servers are not really slow and also couple other network devices were slow,and had intermittent on off connections .All these were running in vlan 5.

(Servers,ACE,Network Devices ) connected to a 6509 switch.

After disabling the ports on 6509 switch for ACE,Everything started working fine.

Not sure what triggered this performance issue ,but currenly we disable ACE from the network in the lab and everthing is working as before.

These are the files I see in image dir
