Configuring Loop Protection

Use the Loop Protection page to configure loop detection, including loop detection PDU transmission interval,
response to detected loop, shutdown time for ports with a detected loop, and active/passive participation in
loop detection process.

• Transmission Time The interval at which loop protection PDUs are sent on each port. (Range: 1-10

A trunk formed with another switch using LACP will automatically be assigned the next available
trunk ID.
If more than eight ports attached to the same target switch have LACP enabled, the additional ports
will be placed in standby mode, and will only be enabled if one of the active links fails.
All ports on both ends of an LACP trunk must be configured for full duplex, either by forced mode
or auto-negotiation.
Trunks dynamically established through LACP will be shown on the LACP System Status page (see
page 162) and LACP Port Status (see page 162) pages under the Monitor menu.
Ports assigned to a common link aggregation group (LAG) must meet the following criteria:
Ports must have the same LACP Admin Key. Using autoconfiguration of the Admin Key will

avoid this problem.
One of the ports at either the near end or far end must be set to active initiation mode.

Aggregation Mode Configuration located under the Static Aggregation menu (see the Configuring
Static Trunks section on page 86) also applies to LACP.

seconds; Default: 5 seconds)
The period for which a port will be disabled if a loop is detected and the response
is set to shut down the port. (Range: 0-604,800 seconds where the maximum is 7
days, and zero means to keep a port disabled until the switch is restarted; Default:
180 seconds)
