What Is Dell-DHCPCL-MIB?

Dell-DHCPCL-MIB is a Dell private MIB that manages DHCP client behavior on Dell network switches, controlling per-interface DHCP client actions and optional administrative approval of DHCP-assigned addresses before they're applied. It exposes a per-interface action table with DHCP client status and hostname, plus an approval-waiting table listing pending DHCP offers (address, mask, gateway) awaiting administrator sign-off when approval mode is enabled. From a monitoring standpoint, this MIB reveals whether a switch interface has successfully obtained network configuration via DHCP or is stuck waiting for manual approval — a growing rlDhcpApprovalWaitingTable indicates addresses are being offered but not approved, which would explain an interface failing to come online with connectivity. It is a Dell-specific private MIB tied to Dell's switch DHCP client implementation rather than a standard IETF DHCP MIB. It is deployed on Dell network switches using DHCP for interface addressing where administrative approval of dynamic addresses is desired for security control. Engineers can download the Dell-DHCPCL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-DHCPCL-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

  • per-interface DHCP client status
  • assigned hostname via DHCP
  • DHCP approval mode enabled/disabled
  • pending DHCP offers awaiting approval
  • offered IP address/mask/gateway

Supported Devices

  • Dell network switches

Monitoring Examples

An admin would check rlDhcpClActionTable/rlDhcpClActionEntry by rlDhcpClActionIfIndex to see the current rlDhcpClActionStatus and hostname assigned via DHCP for a given interface. If rlDhcpApprovalEnabled is set, reviewing rlDhcpApprovalWaitingTable entries (address, mask, gateway per rlDhcpApprovalWaitingIfIndex) shows offers pending sign-off, explaining why an interface hasn't received an IP despite a DHCP server responding. A stalled approval-waiting entry across multiple polls flags a workflow gap where nobody has approved the pending lease.
