Dynamic Link Aggregation
The Switch adheres to the IEEE 802.3ad standard for static and dynamic (LACP)
port trunking.
The IEEE 802.3ad standard describes the Link Aggregation Control Protocol
(LACP) for dynamically creating and managing trunk groups.
When you enable LACP link aggregation on a port, the port can automatically
negotiate with the ports at the remote end of a link to establish trunk groups.
LACP also allows port redundancy, that is, if an operational port fails, then one of
the “standby” ports become operational without user intervention. Please note
that:
• You must connect all ports point-to-point to the same Ethernet switch and
configure the ports for LACP trunking.
• LACP only works on full-duplex links.
• All ports in the same trunk group must have the same media type, speed,
duplex mode and flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch to avoid
causing network topology loops.
Link Aggregation ID
LACP aggregation ID consists of the following information
1
:
