DCS-3950 series Ethernet switch manual
Fig 17-2 Configuring Port Channel in LACP
Example: The switches in the description below are all DCS-3950 series switch and as
shown in the figure, ports 1, 2, 3 of Switch1 are access ports that belong to vlan1. Add
those three ports to group1 in active mode. Ports 6, 7, 8 of Switch2 are trunk ports that
also belong to vlan1,and allow all. Add these three ports to group2 in passive mode. All
the ports should be connected with cables
The configuration steps are listed below:
Switch1#config
Switch1 (Config)#interface eth 0/0/1-3
Switch1 (Config-Port-Range)#port-group 1 mode active
Switch1 (Config-Port-Range)#exit
Switch1 (Config)#interface port-channel 1
Switch1 (Config-If-Port-Channel1)#
Switch2#config
Switch2 (Config)#port-group 2
Switch2 (Config)#interface eth 0/0/6
Switch2 (Config-Ethernet0/0/6)#port-group 2 mode passive
Switch2 (Config-Ethernet0/0/6)#exit
Switch2 (Config)# interface eth 0/0/8-9
Switch2 (Config-Port-Range)#port-group 2 mode passive
Switch2 (Config-Port-Range)#exit
Switch2 (Config)#interface port-channel 2
Switch2 (Config-If-Port-Channel2)#
Configuration result:
Shell prompts ports aggregated successfully after a while, now ports 1, 2, 3of Switch 1
form an aggregated port named ‘Port-Channel1’, ports 6, 7, 8 of Switch 2 forms an
aggregated port named ‘Port-Channel2’; configurations can be made in their respective
aggregated port configuration mode.
Scenario 2: Configuring Port Channel in ON mode.
