TitleHow to configure Dynamic LAG using LACP on 200-Series switches
Objective
Procedure to create a dynamic LAG (Port-Channel) using LACP on 200 Series switches
Environment
  • 200 Series switches
  • All firmware version
  • Port-Channel
  • LACP
  • LAG
  • 802.3ad
  • 802.1ax
Procedure
The following procedure creates a dynamic LAG using LACP to use two ports, 14 and 15 on a 220-Series switch
 
(Extreme 220) #configure
(Extreme 220) (Config)#interface 1/0/14-1/0/15
(Extreme 220) (Interface 1/0/14-1/0/15)#addport lag 1
(Extreme 220) (Interface 1/0/14-1/0/15)#exit

(Extreme 220) (Config)#interface lag 1
(Extreme 220) (Interface lag 1)#no port-channel static
(Extreme 220) (Interface lag 1)#port-channel local-preference
(Extreme 220) (Interface lag 1)#exit

(Extreme 220) (Config)#interface 0/3/1
(Extreme 220) (Interface 0/3/1)#vlan participation include 1
(Extreme 220) (Interface 0/3/1)#
(Extreme 220) (Interface 0/3/1)#exit
(Extreme 220) (Config)#exit
(Extreme 220) #write memory confirm

Additional notes
  • A total of 6 LAGs can be configured on the 200 Series switches
  • The default logical interfaces for LASs are 0/3/1 - 0/3/6 on 220-Series and 3/1 - 3/6 on the 210-Series
  • The default Channel names are ch1 - ch6
  • Where a stack is configured Local Preference mode should be enabled
  • The default Load Balance algorithm is
  • 3. Source/Destination MAC, VLAN, EtherType, and incoming port associated with the packet
