i-rule not being triggered on a virtual server

MMS_TrafficFilter_Profile is the HTTP profile. If there wasn't an HTTP profile added to the VS, you'd get an error when trying to add the iRule to the VS.

 

 

As you have an else case, something should be logged for every HTTP request to the virtual server. If you don't see anything logged for requests, I'd guess that requests might be coming in on a VLAN which the VS isn't enabled on. Can you try curling the VS directly from the command line of the LTM? You can use something like:

 

 

curl -v http://1.2.3.4:8080/ -H "Host: 192.168.220.8"

 

 

This will send an HTTP request to the VS on 1.2.3.4 port 8080 with the HTTP host header set to the IP address 192.168.220.8.

 

 

Also, when you say that requests make it to the VS, but nothing is logged, how are you determining this? Are you checking /var/log/ltm and the VS stats or a tcpdump?
