Description: Enterasys Networks proprietary extension to the IETF P-BRIDGE-MIB (RFC 2674) for priority and traffic class settings.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is ENTERASYS-IETF-P-BRIDGE-MIB-EXT-MIB?
This is an Enterasys Networks enterprise MIB extending the IETF P-BRIDGE-MIB (RFC 2674) with additional per-port priority and traffic-class objects for Enterasys switches. It exposes QoS-related configuration data, specifically per-port 802.1p priority rewrite behavior, which affects how traffic is classified and remapped as it traverses a switch port. Its monitoring value lies in confirming that priority rewrite policies are applied as expected on specific ports, helping diagnose why traffic is being reprioritized or dropped into the wrong queue rather than any hardware fault. It is explicitly designed to be used together with the standard P-BRIDGE-MIB from RFC 2674, extending rather than replacing its priority and traffic class tables. It is deployed in enterprise networks running Enterasys/Extreme switches where administrators need to enforce or troubleshoot Layer 2 QoS priority mapping. Engineers can download the ENTERASYS-IETF-P-BRIDGE-MIB-EXT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-IETF-P-BRIDGE-MIB-EXT-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.
Supported Devices
- Enterasys (Extreme Networks) enterprise switches
Monitoring Examples
An administrator would poll etsysDot1dPortPriorityTable / etsysDot1dPortPriorityEntry and specifically etsysDot1dPortPriorityRewrite on a given port to verify whether incoming 802.1p priority tags are being rewritten to a different priority value. If voice or video traffic is arriving with the wrong priority downstream, checking this rewrite setting on the ingress port is a natural first troubleshooting step, since the etsysDot1dPriority group governs this remapping behavior directly.
What Can Be Monitored
- per-port 802.1p priority rewrite setting
- port priority table entries

Enterasys Networks P-Bridge proprietary MIB extensions for priority-tagged bridge port management.
Start monitoring Enterasys Networks switch (legacy, later Extreme Networks) (P-BRIDGE-MIB extensions, priority rewrite) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
