Management and Configuration Guide K/KA/KB.15.15

In the above example, if the port on the other end of the link is configured for active LACP or static
LACP, the trunked link will be re-established almost immediately.
Setting the LACP key
During dynamic link aggregation using LACP, ports with the same key are aggregated as a single
trunk.
Syntax
[no]lacp [[active] | [passive] | [key 0-65535]]

Viewing existing port trunk groups (WebAgent)
While the WebAgent does not enable you to configure a port trunk group, it does provide a view
of an existing trunk group.
To view any port trunk groups:
1. In the navigation pane, click Interface.
2. Click Port Info/Config. The trunk information for the port displays in the Port Properties box.
Viewing and configuring a static trunk group (Menu)
IMPORTANT: Configure port trunking before you connect the trunked links to another switch,
routing switch, or server. Otherwise, a broadcast storm could occur. (If you need to connect the
ports before configuring them for trunking, you can temporarily disable the ports until the trunk is
configured. See "Enabling or Disabling Ports and Configuring Port_Mode".)
