link is restored, that link is automatically included in the traffic distribution
again. The LACP option also offers a standby link capability, which enables
you to keep links in reserve for service if one or more of the original active
links fails. See “Trunk Group Operation Using LACP” on page 6-23.)
Trunk Configuration Methods
Dynamic LACP Trunk : The switch automatically negotiates trunked links
between LACP-configured ports on separate devices, and offers one dynamic
trunk option: LACP. To configure the switch to initiate a dynamic LACP trunk
with another device, use the
interface ethernet command in the CLI to set the
default LACP option to
Active
on the ports you want to use for the trunk. For
example, the following command sets ports 1-4 to LACP active:
SMC6624M(config) int e 1-4 lacp active
Note that the above example works if the ports are not already operating in a
trunk. To change the LACP option on ports already operating as a trunk, you
must first remove them from the trunk. For example, if ports 1 - 4 were LACP-
active and operating in a trunk with another device, you would do the
following to change them to LACP-passive:
SMC6624M(config)# no int e 1-4 lacp
Removes the ports from the trunk.
SMC6624M(config)# int e 1-4 lacp passive
Configures LACP passive.
Static Trunk:
The switch uses the links you configure with the Port/Trunk
Settings screen in the menu interface or the
trunk
command in the CLI to create
a static port trunk. The switch offers two types of static trunks: LACP and
Trunk.
