here I'm again trying to get some insight to my clients cache issues:
We recently wanted to separate Youtube traffic from the global cache pool and make a separate 3-cache pool, we hit a major issue, the moment we added the paramters/class-maps/policy-maps, we saw ACE dropping 80% of normal existing traffic and we were left with an outage of the web, the ACE just wont pass traffic, even after we removed the class-maps and polices and reloading the ACE module , had to reboot the c6500s
Here the config:
rserver host BCXX
ip address X.X.X.X
rserver host BCYY
ip address Y.Y.Y.Y
rserver host BCZZ
description YOUTUBE -z
ip address Z.Z.Z.Z
serverfarm host LEASTCONNECTIONS_FARM
description Transparent Proxy Least Connection Farm
predictor leastconns slowstart 60
serverfarm host YOUTUBE_FARM
class-map type http loadbalance match-any YOUTUBE-1
2 match http header Host header-value "www.youtube.com"
class-map type http loadbalance match-any YOUTUBE-2
2 match http url /get_video.*
sticky ip-netmask 255.255.255.255 address both STICKY_SF
policy-map type loadbalance first-match TRANSPARENT_LB_PM
, We saw some buffer crunches but not sure, we are running A2(1.3) .
last year we had same config with ONLY mathcing URL /get_video.* and was working fine with dest_ip hashing,
this time we added the host www.youtube.com and 3 separate caches.
doesnt seem to make sense to us,
if anyone has worked to segregate U-tube , do share their config philosophy.
we are thinking about separate context or diff policies, but that's too much config related, still all options open.
do let me now champs..
