Field	Description

Broadcast threshold	Shows if broadcast storm suppression is enabled or disabled; if
	enabled it also shows the threshold level (page 4-177).

LACP status	Shows if Link Aggregation Control Protocol has been enabled
	or disabled (page 4-190).

Ingress/Egress rate	Shows if rate limiting is enabled, and the current rate limit
limit	(page 4-187).

VLAN membership	Indicates membership mode as Trunk or Hybrid (page 4-234).
mode

Ingress rule	Shows if ingress filtering is enabled or disabled (page 4-236).

Acceptable frame	Shows if acceptable VLAN frames include all types or tagged
type	frames only (page 4-235).

Native VLAN	Indicates the default Port VLAN ID (page 4-237).

Priority for untagged	Indicates the default priority for untagged frames (page 4-253).
traffic

Gvrp status	Shows if GARP VLAN Registration Protocol is enabled or
	disabled (page 4-250).

Allowed Vlan	Shows the VLANs this interface has joined, where “(u)”
	indicates untagged and “(t)” indicates tagged (page 4-238).

Forbidden Vlan	Shows the VLANs this interface can not dynamically join via
	GVRP (page 4-239).

Private VLAN mode	Shows the private VLAN mode as host, promiscuous, or none
	(page 4-245).

Private VLAN	Shows the secondary (or community) VLAN with which this
host-association	port is associated (page 4-245)..

Private VLAN	Shows the primary VLAN mapping for a promiscuous port
mapping	(page 4-246).
