I am trying to configure an ACE 4710 appliance. The ace is connected to a 4500 switch and the client and server connections are on the same subnet.
I am not able to ping the VIP or connect via HTTP. The VIP doesn't appear when in the ARP cache when I issue the show arp command.
From the ACE I am able to ping addresses on the 4500 switch and addresses beyond the switch. I can also ssh into servers beyond the 4500 switch from the ACE.
The config is attached.
Hoping someone can point me in the right direction.
Thanks,
Jeff

Jeff,
Your VIP should be a /32 mask IP and that's the default on the ACE, try to rewrite your VIP without a network mask.
class-map match-all EAS_SAND 2 match virtual-address 161.80.201.199 tcp eq www
Let us know if this helps.

I wonder if you try to add the http probe on the serverfarm it would make the rserver alive and therefore the VIP active?
Thanks,

Hi Jeff,
Seems like you didn't apply the ACL to permit the traffic to flow through the ACE, the ping from ACE to 4500 because is traffic originated on the appliance.
Try this:
interface vlan 196 ip address 161.80.201.254 255.255.255.0 service-policy input int196
access-group input EAS_ACL
no shutdown
Also if your clients and servers are on the same subnet you might need source NAT to avoid asymmetric routing.
HTH.

I added the input ACL and still get the same result.
I also added an http probe to the real server, but no luck.
Thanks for the suggestions.

Jeff,
Can you get a full show running from the Admin context (showing interface config), also get the output of
show serverfarm EAS det
show arp
show service-policy int196
Regards.

you will also need the management policy on interface 196.
So add "service-policy input EAS".

Jeff,
allocate resource for the context.
Assign 10% min to all resources and unlimited max.
resource-class Basic
limit-resource all minimum 10.00 maximum unlimited
context EAS
member Basic
After that, it still does not work, try to reboot the box.

Gille,
I tried allocating the resources to it, but still no luck. I have tried rebooting the ACE with no luck.
I was running software A3.26 and tried going back to A3.20 with no luck.
For whatever reason I can't get the VIP to appear in the ARP cache.
Thanks,
Jeff

Pablo,
that's a good catch... well done.
Gilles.

Pablo,
That worked. Thanks
I am now able to ping the VIP and it appears in the APR cache.
