LAG on Access

Link Aggregation Groups (LAG) is supported on access ports and access-uplink ports. This is
treated the same as LAG on network ports which provides a standard method to aggregate
Ethernet links. The difference lies in how QoS is handled.

Ports can be added or removed from the LAG while the LAG and its ports (other than the
port being removed) remain operational. When ports to and/or from the LAG are added or
removed, the hashing algorithm is adjusted for the new port count.
The show commands display physical port statistics on a port-by-port basis or the entire
LAG can be displayed.
LAG is supported on Ethernet ports.
Ports of a particular LAG can be of different types but they must be the same speed and
duplex. To guarantee the same port speed is used for all ports in a LAG, auto-negotiation
must be disabled or in limited mode to ensure only a specific speed is advertised.
