Re: LACP/Ethernet

I think to make it etherchannel only we have to make it "on"

Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int range
Router(config)#int range f1/0 - 4
Router(config-if-range)#chan
Router(config-if-range)#channel-group ?
  <1-6> Channel group number

Router(config-if-range)#channel-group 1 ?
  mode Etherchannel Mode of the interface

Router(config-if-range)#channel-group 1 mode ?
  on Enable Etherchannel only

for LACP we need to make it active or passive
and etherchannel mode are on, auto, desirable ?
