I need to get these moved from the Cisco switch they are presently plugged into, over to my new stack of Extreme Summit 450-G2 switches. The wireless controllers each have two ports that are configured as channel group ports.<BR /> <BR /> Here is what the Cisco switch port configuration looks like:<BR /> <BR /> interface GigabitEthernet9/3 description OD WAP CONTROLLER 2 PORT 1 switchport switchport trunk encapsulation dot1q switchport trunk native vlan 70 switchport mode trunk no ip address mls qos trust dscp channel-group 5 mode on!interface GigabitEthernet9/4 description OD WAP CONTROLLER 2 PORT 2 switchport switchport trunk encapsulation dot1q switchport trunk native vlan 70 switchport mode trunk no ip address mls qos trust dscp channel-group 5 mode on!<BR /> Normally when I am connecting Cisco switches to Extreme, I change the Cisco side to "channel-group 5 mode <B>active</B>", and then on my Extreme side I would do something like this "enable sharing 1:49 grouping 1:49-50 algorithm address-based L2 lacp".<BR /> <BR /> The problem with these old wireless controllers is that they do not support "mode <B>active</B>", only "mode on". According to Cisco documentation, "mode on" means "Enable Etherchannel only".<BR /> <BR /> Can someone give me a hint on how I would match this on the Extreme switch? I took a few guesses, and failed to bring the device up.<BR /> <BR /> Wed, 11 Oct 2017 20:30:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/configure-lag-ports-for-cisco-switch-where-quot-mode-on-quot-is/m-p/50756#M13682 Steve_Ballantyn 2017-10-11T20:30:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/configure-lag-ports-for-cisco-switch-where-quot-mode-on-quot-is/m-p/50757#M13683 That mode is for failover, not for LACP sharing Wed, 11 Oct 2017 21:23:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/configure-lag-ports-for-cisco-switch-where-quot-mode-on-quot-is/m-p/50757#M13683 Nick_Yakimenko 2017-10-11T21:23:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/configure-lag-ports-for-cisco-switch-where-quot-mode-on-quot-is/m-p/50758#M13684 Well that explains why <U>sharing </U>doesn't work!
