My name is Gary Rollie I am a Global Solution Engineer, I have a CCIE, JNCIE, as well as many other certs and publications. I currently work for Enterasys and have worked here for the past 6 years. On the ETS side it’s really simple. SSA-150-Fiber(su)->set lacp enable SSA-150-Fiber(su)->set port lacp port ge.1.1-12 enable This sets ports ge.1.13 to ge.1.24 to process lacp. This is the simplest way to make it work quickly. The more secure way is to define the ports and use a static lag. That said to convert it from dynamic to static doesn't take the lag down, so it can be a follow up task after the lag is established. On the Cisco side it’s a little more complicated. On the Cisco Switch these commands work across almost all models of the Cisco Switch line. CORE-HOU-01#conf t CORE-HOU-01(config)#interface range gigabitEthernet 0/49 – 52 I use the interface range command here to make the changes to 4 interfaces; this is similar to our ge.1.1-4 command. CORE-HOU-01(config-if-range)#lacp port-priority 888 I picked 888 any number from 1-65535 works this allows the port to join the lacp group CORE-HOU-01(config-if-range)#channel-group 1 mode active The Active part of the channel group command sets up the port channel on the Cisco side to talk LACP, if you don't do that the Cisco will revert to PaGP (Cisco proprietary protocol. Note: if you have a channel-group 1 defined this ports will be added to that channel-group if you have not created channel-group 4 the Cisco will automatically create an interface called po1/4 This is the output CORE-HOU-01(config-if-range)#channel-group 1 mode active Creating a port-channel interface Port-channel 1 CORE-HOU-01(config-if-range)#
