Hi, I know all sols (at least I think so:-) about vs (or listener) precedence (talking about 11.2.0, so no source facter here). Still I cant't see info about precedence for such setup (let's use Performance (Layer4) type). Destination for both: 0.0.0.0:* (so full wildcard) Protocol: TCP or UDPAll protocols I assume that for TCP traffic matching Destination (as only match among other VSs) VS with protocol set TCP will be best match - still I can't see any explicit info so if someone more experienced can confirm I will appreciate (sure can do the test but right now my Lab is not working).

VS precedence

Hi,

I know all sols (at least I think so:-) about vs (or listener) precedence (talking about 11.2.0, so no source facter here). Still I cant't see info about precedence for such setup (let's use Performance (Layer4) type).

Destination for both: 0.0.0.0:* (so full wildcard)

Protocol:

TCP or UDP
All protocols

I assume that for TCP traffic matching Destination (as only match among other VSs) VS with protocol set TCP will be best match - still I can't see any explicit info so if someone more experienced can confirm I will appreciate (sure can do the test but right now my Lab is not working).

I am not sure if I understand this setup correctly. I have a forwarding (IP) virtual server configured, but when I run the command tmsh list ltm virtual (virtual_server_name) I do not see the destination port as being port 0, but "any" instead. I'm assuming that both mean the same thing, but just wanted to make sure.

  Hi, Yes, 0 and Any is equal, look at the VS list in GUI, there is info in Service Port column 0 (Any). Piotr

I have a forwarding (IP) virtual server configured, but when I run the command tmsh list ltm virtual (virtual_server_name) I do not see the destination port as being port 0, but "any" instead.

root@(ve11c)(cfg-sync In Sync)(Active)(/Common)(tmos) list cli global-settings service
cli global-settings {
    service name
}
root@(ve11c)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual fwd
ltm virtual fwd {
    destination 0.0.0.0:any
    mask any
    profiles {
        fastL4 { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address disabled
    translate-port disabled
    vlans {
        v423
    }
    vlans-enabled
    vs-index 44
}
root@(ve11c)(cfg-sync In Sync)(Active)(/Common)(tmos) modify cli global-settings service number
root@(ve11c)(cfg-sync Not All Devices Synced)(Active)(/Common)(tmos) list ltm virtual fwd
ltm virtual fwd {
    destination 0.0.0.0:0
    mask any
    profiles {
        fastL4 { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address disabled
    translate-port disabled
    vlans {
        v423
    }
    vlans-enabled
    vs-index 44
}
