Cisco ACE module missing licence file - no connectivity

Hi,

We have 2 ACE modules that were delivered without any licenses.

There is no IP connectivity whatsoever to these modules and I'm guessing this is due to the fact there are no licenses installed.

Have tried asking Cisco to no avail - and am not sure if there is an actual problem with them or not.

The VLANs are assigned correctly and I can see inbound ICMP echo from the 6509 that its hosted in, but no outbound packets ever leave the ACE. I've applied a mgmt policy to enable ping/telnet/ssh etc.

switch/Admin# sh vlans

Total arp entries 4

The ARP table for the adjacent switch SVI has a valid MAC upon reboot, but soon after resets to 00.00.00.00.00.00

Problem is that once Cisco eventually send me the license file I have no way of TFTP'ing it to the ACE module.

Any suggestions/advice?

Re: Cisco ACE module missing licence file - no connectivity

You do not need a license for basic configuration.

The module seems to receive traffic but arp table being empty, there is nothing going out.

Could you get a 'show resource usage' and a 'show cde health'

Try to increase your "mgmt-connections"

Thanks.

Re: Cisco ACE module missing licence file - no connectivity

Thanks for the info - so I should at least be able to connect to a license-less ACE at least, but these modules seem to have a problem.

If the modules are reloaded (from the ACE) or reset (from the Supervisor) they initially have the ARP entry (however still cannot communicate to the attached Supervisor via SVI) which eventually resets.

Your traffic is being denier.

Apparently you have associated too much BW to the other context.

Try to create a resource class with 10% resources guaranteed for the admin context.

Also adjust the other context resources.

Re: Cisco ACE module missing licence file - no connectivity

Gilles,

Thanks for your help - the ACE was allocating 100% of resources to the contexts leaving none left for Admin. Reason this was not happening on the other modules was that they had 3 contexts each using 33% (leaving 1% for default context for Admin).

The 'problem' ACE modules had 4 contexts each using 25% (leaving nothing for Admin as you suggested).

I've since changed to allow 1% for Admin and all is now working(FT groups also working fine).

Is there a recommendation from Cisco as to how much resource usage to allocate for Admin context - I've only allowed 1% currently - should I use 10% as a guide instead?

Thanks again!

Cisco Employee

Re: Cisco ACE module missing licence file - no connectivity

I'm glad you got it working.

If your admin context is not being used to handle traffic, I think 1% is enough resource.

Gilles.
