Description: Provides NMS Communications extended private VLAN objects for promiscuous and isolated port management.
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 NMS-PVLAN-EXT-MIB?
NMS-PVLAN-EXT-MIB is a private MIB (NMS-SMI enterprise family) extending standard Private VLAN (PVLAN) support. Its VLAN table records each VLAN's primary VLAN ID, private-VLAN type (primary/isolated/community), and associated VLAN/port-list mappings, alongside a port table recording each port's private-port type and associated PVLAN. As a configuration MIB it lets an administrator confirm a port's private-VLAN role (isolated vs. community) and its association to the correct primary VLAN. It is deployed on switches (NMS SMI platform family) using Private VLANs for host isolation. Engineers can download the NMS-PVLAN-EXT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NMS-PVLAN-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
- nms Co., Ltd. switch using Private VLANs (vendor unidentified)
Monitoring Examples
An administrator checks pvlanPrivatePortType for a port that shouldn't be able to reach other hosts on the same VLAN, confirming it's correctly configured as isolated rather than community.
What Can Be Monitored
- private-VLAN type and port association
