Port Channel Example - Digitalchina Networks DCS-3950 series Manual

DCS-3950 series Ethernet switch manual
Parameters: <port-group-number> is the group number of port channel, from 1 to 8;
active enables LACP on the port and sets it in Active mode; passive enables LACP on
the port and sets it in Passive mode; on forces the port to join a port channel without
enabling LACP.
Command mode: Interface Mode
Default: Switch ports do not belong to a port channel by default; LACP not enabled by
default.
Usage Guide: If the specified port group does not exist, a group will be created first to add
the ports. All ports in a port group must be added in the same mode, i.e., all ports use the
mode used by the first port added. Adding a port in 'on' mode is a 'forced' action, which
means the local end switch port aggregation does not rely on the information of the other
end, port aggregation will succeed as long as there are 2 or more ports in the group and
all ports have consistent VLAN information. Adding a port in 'active' or 'passive' mode
enables LACP. Ports of at least one end must be added in 'active' mode, if all the ports are
in passive mode, they can not form a group.
Example: In the port mode for ethernet 0/0/1, configure the port to be added to port group
1 in active mode.
Switch(Config-Ethernet0/0/1)#port-group 1 mode active
17.2.2.3 interface port-channel
Command: interface port-channel <port-channel-number>
Function: Enter the port channel configuration mode
Command mode: Global Mode
Default：None
Usage Guide: On entering aggregated port mode, configuration to GVRP or spanning
tree modules will apply to aggregated ports; if the aggregated port does not exist (i.e.,
ports have not been aggregated), an error message will be displayed and configuration
will be saved and will be restored until the ports are aggregated. Note such restoration will
be performed only once, if an aggregated group is ungrouped and aggregated again, the
initial user configuration will not be restored. If it is configuration for modules, such as
shutdown or speed configuration, then the configuration to current port will apply to all
member ports in the corresponding port group.
Example: Enter configuration mode for port-channel 1.
Switch(Config)#interface port-channel 1
Switch(Config-If-Port-Channel1)#
