configuring L2 etherChannel

As you will see here, to utilize all the bandwidth, we created L2 ether-channel by combining both links and the commands to do that are the following:


Switch#config t
Switch(config)#int range fa0/1 - 2
Switch(config-if-range)#channel-protocol ?

  lacp  Prepare interface for LACP protocol
  pagp  Prepare interface for PAgP protocol

Switch(config-if-range)#channel-protocol lacp
Switch(config-if-range)#channel-group 12 ?

  mode  Etherchannel Mode of the interface

Switch(config-if-range)#channel-group 12 mode ?

  active        Enable LACP unconditionally
  auto          Enable PAgP only if a PAgP device is detected
  desirable  Enable PAgP unconditionally
  on            Enable Etherchannel only
  passive    Enable LACP only if a LACP device is detected

Switch(config-if-range)#channel-group 12 mode active ?
  <cr>
Switch(config-if-range)#channel-group 12 mode active

%LINK-5-CHANGED: Interface Port-channel 12, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel 12, changed state to up
Switch(config-if-range)#end
