Cisco Nexus: VLAN port status Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoNexus.VLANPortStatus.2.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the VLAN port status has changed its state.

Knowledge Base article:

Summary

VLAN port status has changed.

The VLAN port status has changed to one of the following states: inactive, active, shutdown or VLAN active fault.

Causes

Active is the desired state, which indicates that the currently assigned VLAN is active. Inactive indicates that a dynamic port does not yet have a VLAN assigned, or a port is assigned to a VLAN that is currently not active. Shutdown indicates that the port has been disabled as a result of VQP shutdown response. When you delete a VLAN, any port assigned to that VLAN becomes inactive. They remain associated with the VLAN (and thus inactive) until you assign them to a new VLAN.

If you have a VLAN Membership Policy Server (VMPS) configured and the VLAN is not allowed on the port and the VMPS is in secure mode, the VMPS sends a "port-shutdown" response. If the VLAN in the database does not match the current VLAN on the port and active hosts exist on the port, the VMPS sends an access-denied or a port-shutdown response, depending on the secure mode of the VMPS.

Resolutions

No action required when active. Both disabled and shutdown states require you to re-enable the port and correct configuration if necessary. To re-enable a shut-down dynamic port, enter the "no shutdown" command in interface configuration mode.

Additional

Monitors the status of the port on the VLAN to which it was assigned on a Cisco Nexus.
