Cisco ACE ARP_FAILED

Darren Frowen
Level 1
Level 1

Hi,

 

Hoping someone can help, we have a serverfarm failing with ARP_FAILED. The server farm is configured to use Vlan275 and the real servers are routable from the ACE via this interface. We can ping the real servers from the ACE and also all health checks are working fine but for some reason which i cannot inderstand the serverfarm is failed with the ARP error. Technically the ACE shouldnt be ARPing for the Real servers as they are not local these are routed via static route and we know this is working as we can ping the real servers?

 

ACE01a/DMZ_General# show serverfarm EXCH_HTTPS
 serverfarm     :EXCH_HTTPS, type: HOST
 total rservers : 2
