Description: Manages DHCP client configuration and lease status for the Dell VRTX switch module.

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 Dell-VRTX-DHCPCL-MIB?

This private MIB module manages DHCP client behavior on a Dell PowerEdge VRTX chassis switch module, built on the RAD/"rl"-prefixed embedded switch OS common to several Dell-branded switching products. It exposes per-interface DHCP client action/status data and a DHCP approval mechanism that lets an administrator review and approve DHCP-assigned addresses before they take effect. As monitoring/status data it surfaces DHCP client action status per interface (rlDhcpClActionStatus), the assigned host name (rlDhcpClActionHostName), and a waiting-approval table showing address, mask, and gateway pending administrator sign-off -- useful for confirming whether a management interface obtained a valid address or is stalled. It works alongside standard IETF interface and IP addressing MIBs since DHCP client status is tied to a specific ifIndex. It is deployed on the management/network interfaces of Dell VRTX chassis switch modules where DHCP is used for automatic address assignment requiring administrative approval before activation. Engineers can download the Dell-VRTX-DHCPCL-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would poll rlDhcpClActionTable/rlDhcpClActionEntry keyed by rlDhcpClActionIfIndex to see the current rlDhcpClActionStatus and rlDhcpClActionHostName for the management interface, confirming whether a DHCP lease was successfully obtained. If rlDhcpApprovalEnabled is set, the rlDhcpApprovalWaitingTable would be checked for entries stuck awaiting approval (rlDhcpApprovalWaitingAddress, rlDhcpApprovalWaitingGateway) which would explain why an interface has not come up with a usable IP address. A stalled or empty status here typically indicates a DHCP server reachability problem or an unapproved lease blocking connectivity.
