Website loadbalancing failure - Error page?

networker99 — Tue, 26 Oct 2010 18:00:03 GMT

We currently have a Cisco ACE 4710 that has a server farm load balancing a webpage. Is there anyway for the ACE to present a custom error page if all servers in the farm is unavailable, or would I have to create a 3rd server entry and make it a redirect to another website?

Hi,

One option would be configuring a specific serverfarm to which you can redirect requests, if the primary serverfarms fails or the associated probe receives an undesired responsecode (eg. 500). Could look something like this:

probe type http CHK_WEB

request method get url /[string]

expect status 200 200

rserver WEB_SRV_A

ip addr x.x.x.x

inser

rserver WEB_SRV_B

ip addr y.y.y.y

inser

rserver OUT_OF_SRVC

ip addr z.z.z.z

inser

serverfarm host SFARM_WEB

probe CHK_WEB

rserver WEB_SRV_A [dst.port]

inser

rserver WEB_SRV_B [dst.port]

inser

serverfarm host OUT_OF_SRVC

rserver OUT_OF_SRVC [dst.port]

inser

policy-map type loadbalance first-match PMAP_LB_WEB

class [class-name]

serverfarm SFARM_WEB backup OUT_OF_SRVC

Don't know if this is what you're looking for, but maybe it'll do.
