Since we saved some cash by purchasing more 2×2 3705i
Enterasys Extreme Networks AP’s instead of 3×3 AP’s during our AP upgrades, we were able to purchase a few other items. We picked up three c5g Enterasys Extreme Networks 48 port POE switches, gbics, and a few other parts. The first thing I did after we deployed 96 AP’s in our dorm rooms was setup 802.3ad link aggregation with my extra gbic’s from our current N3 chassis to our g3 series switch. Phase two will be to install another DFE blade in the N3 chassis and spread the link aggregation between two DFE blades.
On with the
Enterasys Extreme Networks switch commands:
1.) Egress all the proper vlan’s you want trunked across the additional physical port. We will be setting up a lag.0.x port and at that point, the physical port egress no longer matters, but if the lag breaks down for some reason, then the physical port will have the correct vlan’s trunked. You could also ensure that the single port lag command is set, but again I like to have the extra safety precautions in place.
Example ->set vlan egress ->set vlan egress 20 ge.4.24
2.) Egress all the proper vlan’s on the lag port. Use the “show lacp” command to view the available lags and to make sure that lacp is globally enabled.
Example ->set vlan egress
->set vlan egress 20 lag.0.1
3.) Create a unique lacp admin key to statically set which ports will be joined to the lag
Example ->set lacp aadminkey
->set lacp aadminkey lag.0.1 20
4.) Set the aadminkey to the physical port
->set port lacp port ge.4.24 aadminkey 20
5.) Perform the same commands on the other switch that you will be connecting to. The aadminkey can be different on the other switch, but I like to try and use the same admin key on the opposite end if possible. Make sure you also have lacp enabled on the physical interfaces as well.
