Configure Port Thresholds
Configure port thresholds to prevent traffic on a LAN from being disrupted by a
broadcast, multicast, or unicast storm on one of the physical interfaces.
To configure port thresholds, from the Configure menu, choose Port Thresholds.
Operational Mode The operational state of the port. Displays the administrative mode or Down (if disabled).
Access VLAN The VLAN that an interface belongs to and carries traffic for, when the link is configured as or is acting as a nontrunking interface.
Administrative Mode Displays one of the following administrative modes:
• Access—The interface is in permanent nontrunking mode and negotiates to convert the neighboring link into a nontrunk link even if the neighboring
interface is a trunk interface. If you choose this option, also choose an Access VLAN. An access port belongs to and carries the traffic of only one VLAN
(unless it is configured as a voice VLAN port).
• Trunk—The interface is in permanent trunking mode and negotiates to convert the neighboring link into a trunk link even if the neighboring interface
is not a trunk interface. If you choose this option, also choose whether to allow All VLANs or specified VLAN IDs
• Dynamic Auto—The interface converts the link to a trunk link if the neighboring interface is set to trunk or desirable mode. This mode is the default
setting. If you choose this option, specify an Access VLAN to use when the link is in access mode. Also specify whether to allow All VLANs or specified
VLAN IDs when the link is in trunk mode.
• Dynamic Desirable—The interface converts the link to a trunk link if the neighboring interface is set to Trunk, Dynamic Desirable, or Auto mode. If you
choose this option, specify an Access VLAN to use when the link is in access mode. Also choose whether to allow All VLANs or specified VLAN IDs when
the link is in Trunk mode.
