10.2.1 Static LACP Aggregation
Static LACP aggregation is enforced by users configuration, and do not enable LACP protocol.
When configuring static LACP aggregation, use “on” mode to force the port to enter the
aggregation group.
10.2.2 Dynamic LACP Aggregation
1. The summary of the dynamic LACP aggregation
Dynamic LACP aggregation is an aggregation created/deleted by the system automatically, it
does not allow the user to add or delete the member ports of the dynamic LACP aggregation.
The ports which have the same attribute of speed and duplex, are connected to the same
device, have the same basic configuration, can be dynamically aggregated together. Even if
only one port can create the dynamic aggregation, that is the single port aggregation. In the
dynamic aggregation, LACP protocol of the port is at the enable state.
2. The port state of the dynamic aggregation group
In dynamic aggregation group, the ports have two states: selected or standby. Both selected
ports and standby ports can receive and send LACP protocol, but standby ports can not
forward the data packets.
Because the limitation of the max port number in the aggregation group, if the current number
of the member ports exceeds the limitation of the max port number, then the system of this end
will negotiates with the other end to decide the port state according to the port ID. The
negotiation steps are as follows:
Compare ID of the devices (the priority of the system + the MAC address of the system). First,
compare the priority of the systems, if they are same, then compare the MAC address of the
systems. The end with a small device ID has the high priority.
Compare the ID of the ports (the priority of the port + the ID of the port). For each port in the
side of the device which has the high device priority, first, compare the priority of the ports, if
the priorities are same, then compare the ID of the ports. The port with a small port ID is
selected, and the others become the standby ports.
In an aggregation group, the port which has the smallest port ID and is at the selected state
will be the master port, the other ports at the selected state will be the member port.
10.3 Port Channel Configuration Task List
1. Create a port group in Global Mode
2. Add ports to the specified group from the Port Mode of respective ports
3. Enter port-channel configuration mode
