What Is DES-1228P-MIB?

DES-1228P-MIB is a D-Link vendor-specific MIB for the DES-1228P series PoE smart switches, extending the company's enterprise tree (des-1228pa1) with groups for SNMP community management (commSetTable/commGetTable), miscellaneous system control, spanning tree, VLANs (companyTVlanGroup), port trunking, Power-over-Ethernet (companyPoEGroup, including poePortTable's per-port poeportpowerlimit), 802.1X, LLDP, QoS, traffic management, and security. It also defines PoE-specific trap enable/disable controls such as commTrapTrapPOEPortOvercurrent and commTrapTrapPOEPortShort for signaling power-delivery faults. This is useful for monitoring PoE power budget and per-port power limits, VLAN/trunk configuration state, and switch-level fault conditions (overcurrent, short-circuit) on these access-layer switches, which are commonly deployed to power IP phones, cameras, and wireless access points. It depends on RFC1213-MIB/RFC1155-SMI conventions for base types, and network teams often search for the DES-1228P-MIB MIB when configuring PoE monitoring on these switches.

IPNetwork Monitor allows you to monitor SNMP objects defined in DES-1228P-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

  • D-Link DES-1228P PoE smart switch series

Monitoring Examples

An operator polls poePortTable for poeportpowerlimit per poeportid to confirm PoE budget allocation, and watches for commTrapTrapPOEPortOvercurrent/commTrapTrapPOEPortShort trap events; a port reporting an overcurrent or short-circuit trap combined with an unexpectedly low configured power limit would indicate a failing powered device or cabling fault on that PoE port.

What Can Be Monitored

  • PoE per-port power limit configuration
  • PoE overcurrent/short-circuit trap status
  • SNMP community set/get table entries
  • VLAN and port trunk configuration
  • spanning tree group settings
  • 802.1X and LLDP extension objects
