For Port Channel to work properly, member ports of the Port Channel must have the
same properties as follows:
)
All ports are in full-duplex mode.
)
All Ports are of the same speed.
)
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 ES4700 series, 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. ES4700 series 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. ES4700 series 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.
