Map Links Calculating total bandwidth on 2 switch ports

[shoodlum]

Hello-

I have a need to add the sum of 2 keys together to show input of an aggrate port on a network switch
The following line works for me on 1 port
In:{SERVER1:net.if.in[ifHCInOctets.1].last(0)}
and
In:{SERVER1:net.if.in[ifHCInOctets.2].last(0)}
I would like to combine the results from both into 1
I have tried using this with no luck
InSERVER1:net.if.in[ifHCInOctets.1].last(0)) + (SERVER1:net.if.in[ifHCInOctets.2].last(0))

Any help would be great
