Aggregation port list.
<

>
VLAN list.
enable
Enables loop detection on the specified VLANs for the aggregation
ports.
disable
Disables loop detection on the specified VLANs for the
aggregation ports.
Guidelines
The
set loopdetect trunk vlan
with
enable
is used to enable loop detection on the specified
VLANs for aggregation ports. Each aggregation port can configure up to eight VLANs
(except PVID). If detection on VLANs is enabled but detection on PVID is not enabled, this
command can enable the detection on PVID at the same time. If user-defined VLAN IDs
are the same as PVID, this operation is ignored. The
set loopdetect trunk vlan
command
with
disable
is used to disable loop detection on the specified VLANs for aggregation ports.
Note that only detection on the user-defined VLAN IDs can be disabled. Detection on PVID
cannot be disabled.
