Configuring the Link Aggregation Control Protocol (LACP) SmartTRUNK Configuration Guide
Configure the aggregator’s (SmartTRUNK’s) LACP properties using the lacp set aggregator command. Here is
an example:
Note that the following parameters must be specified when using the lacp set aggregator command:
port-type – Specifies whether the ports associated with the aggregator are 10/100 Ethernet ports or Gigabit Ethernet
ports.
actor-key – Specifies the administrative key of the aggregator.
partner-key – Specifies the administrative key of its partner system.
6.3.2 LACP Configuration Example
Consider the following full-mesh topology: Each RS is connected to the other RSs by aggregators. For the sake of
simplicity, each Link Aggregation Group (LAG) consists of just two links. Each link consists of either 10/100 Ethernet
or Gigabit Ethernet. Notice the LACP restriction that each LAG must contain links of identical bandwidth only (either
all 10/100 Ethernet or Gigabit Ethernet, but not both).
