Monitor Capture

Hi All,

Can someone tell me what version of code the monitor capture that Brian uses on his videos is limited to?  He uses the cmds below

R1#monitor capture GRE match any interface gigabitEthernet1.13 bothR1#monitor capture GRE start

But on the routers in my company network I just dont have the option on any of the routers I just usually get this output:

r1#monitor capture ?
  buffer  Control Capture Buffers
  point   Control Capture Points

So is this monitor capture thing limited to 15.x code versions?
