What Is XYLAN-PORT-MIB?

XYLAN-PORT-MIB is a vendor-private MIB from Xylan (later part of Alcatel via the OmniSwitch line) that manages port-level configuration and status on Xylan OmniSwitch Ethernet switches. It exposes per-port objects covering administrative and operational status, negotiated speed and duplex mode, and VLAN membership assignments for each physical switch port. Setting up XYLAN-PORT-MIB SNMP monitoring typically starts with walking the per-port table to baseline operational status, speed, and duplex before layering VLAN-assignment checks on top. Its monitoring value centers on port/interface operational health and configuration rather than deep environmental sensors: tracking a port's operational status alongside its speed/duplex settings reveals cabling or auto-negotiation mismatches, while VLAN assignment objects let an operator audit whether a port is placed in the correct broadcast domain. It is meant to be used alongside standard IF-MIB interface objects and Xylan's other switch-specific MIBs (VLAN, spanning tree) for a complete picture of switch operation. It is deployed in enterprise network closets running legacy Xylan/Alcatel OmniSwitch Ethernet switches.

IPNetwork Monitor allows you to monitor SNMP objects defined in XYLAN-PORT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

  • port administrative and operational status
  • port speed and duplex mode
  • port VLAN assignment
  • port configuration

Supported Devices

  • Xylan OmniSwitch Ethernet switch (legacy per-port configuration)

Monitoring Examples

An administrator would walk the port table to check each port's operational status alongside its negotiated speed and duplex mode, flagging a port stuck at half-duplex as a likely cabling or NIC mismatch. Cross-referencing the VLAN assignment for a given port would reveal if a device was accidentally placed in the wrong VLAN, causing connectivity issues. A port reporting down operational status while administratively enabled would indicate a physical layer fault needing attention.
