I have question related to Cisco ACE behavior in term to taking a decision based on source address
I currently have two servers sits behind ACE part of one server farm, these servers are load balanced via one VIP on ACE module and every things looks fine.
Now service owners want to replace these old servers with new hardware hence before the migration we need to make sure these new servers are working as required standard hence need to create a testing scenario for new servers along with old server. The problem is that number of third party partners are accessing existing servers by hitting VIP on ace and we can't engage all our partner to participate in this test therefore decided to engage only one partner to carry our test with us.
For that reason can we some how configure the ACE so when packet arrive on ACE from one test partner mentioned above, ACE send only that partner's traffic based on it's source address (define via class/policy map on ACE if possible) towards new servers in the existing server farm and not to the old server in the same server farm.
Just to put some config sample that might help you to get this done.
First create the new rservers and include them under a new serverfarm (New-APP)/
serverfarm host Webfarm
serverfarm host New-APP
- Same VIP already working.
class-map match-all VIP-HTTP
2 match virtual-address 10.10.10.10 tcp eq www
- Create a new class that will include your partner's IP(s).
class-map type http loadbalance match-any 3rd-Party
2 match source-address 22.214.171.124 255.255.255.255
3 match source-address 126.96.36.199 255.255.255.255
Modify your current first-match policy to put the new class on top so that all the traffic matched by the statement above (IP) will be redirected to the new farm with the new APP, any other traffic that does not match the "rule" will be sent to the old serverfam with the old app.
policy-map type loadbalance first-match L7-SLB
Since you already have LB working then this is it, nothing needs to be added under the multi-match policy nor interface.
