matchclass ...

Note: matchclass has been deprecated in v10 in favor of the new commands. The class command offers better functionality and performance than matchclass.

Inserting the appropriate class command into this iRule would look something like this:

when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals TLSV1.0_1.1_Enable ]} { SSL::profile example_profile_enable_weak_TLS } else { SSL::profile example_profile_disable_weak_TLS } }
