Port Channel Configuration; Port Channel Configuration Task List - Digitalchina Networks DCS-3950 series Manual

same properties as follows:
All ports are in full-duplex mode.
All Ports are of the same speed.
All Ports are of the same type
All ports are Access ports and belong to the same VLAN or are all Trunk ports.
If the ports are Trunk ports, then their 'Allowed VLAN' and 'Native VLAN' property
should also be the same.
If Port Channel is configured manually or dynamically on DCS-3950 series switch, the
system will automatically set the port with the smallest number to be Master Port of the
Port Channel. If the spanning tree function is enabled in the switch, the spanning tree
protocol will regard Port Channel as a logical port and send BPDU frames via the master
port.
Port aggregation is closely related with switch hardware. DCS-3950 series switch allow
physical port aggregation of any two switches, maximum 8 port groups and 8 ports in each
port group are supported.
Once ports are aggregated, they can be used as a normal port. DCS-3950 series
switch have a built-in aggregation interface configuration mode, the user can perform
related configuration in this mode just like in the VLAN and physical port configuration
mode.
