Dell-EEE-MIB

Description: Manages Energy-Efficient Ethernet (IEEE 802.3az) settings and power saving on Dell switches.

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.

Dell-EEE-MIB is a Dell-specific SNMP module (built on the RADLAN/Marvell rl switch OID naming used across several Dell PowerConnect/Networking switch lines) that manages Energy-Efficient Ethernet, the IEEE 802.3az power-saving feature for switch ports. It exposes objects for globally enabling EEE, per-port administrative and operational EEE status, per-port support/capability, remote-link-partner EEE status, and related LLDP objects used to negotiate EEE parameters with connected devices. Rather than traditional faults or performance counters, its primary monitoring value is configuration/operational-state visibility: administrators use it to confirm EEE is enabled and actually negotiated (operational) on specific ports versus merely administratively enabled, and to check LLDP-advertised EEE capability against the actual link partner. It has a clear dependency on IEEE 802.3az and interacts with LLDP (IEEE 802.1AB) objects for capability negotiation, reflected in its rlEeePortLldpTable. It is typically deployed on Dell managed Ethernet switches in energy-conscious data center or campus environments seeking to reduce port power draw during idle link periods. Network engineers evaluating or troubleshooting this functionality can download the Dell-EEE-MIB file directly to load it into their MIB browser.

An administrator would poll rlEeePortTable, keyed by port, comparing rlEeePortAdminStatus against rlEeePortOperStatus to detect ports where EEE is enabled in configuration but not actually active on the link, often because rlEeePortRemoteStatus shows the connected device does not support it. Checking rlEeePortSupported alongside rlEeePortLldpAdminStatus and rlEeePortLldpOperStatus in rlEeePortLldpTable would reveal whether EEE capability negotiation via LLDP succeeded for a given port. A mismatch pattern across many ports could indicate a firmware or cabling issue interfering with EEE negotiation.
