Description: Manages Cisco Small Business DHCP client configuration and lease status on switch interfaces.

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 CISCOSB-DHCPCL-MIB?

CISCOSB-DHCPCL-MIB is a Cisco Small Business private MIB for managing the DHCP client function on switch management interfaces. It exposes configuration and status data including per-interface DHCP client action/status, assigned hostname, and an approval mechanism where offered DHCP leases (address, mask, gateway) wait for administrative approval before being applied. In monitoring terms this is chiefly a software/network-configuration status module -- it lets an operator verify that a switch's management interface obtained (or is waiting to obtain) a valid IP lease via DHCP, which is essential for the device to remain reachable on the network. It is a vendor-private MIB layered on standard DHCP client concepts rather than a direct extension of an IETF DHCP MIB. It is typically deployed on small-business/SMB Cisco switches where DHCP-based management addressing with an approval safeguard is used. Engineers can download the CISCOSB-DHCPCL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-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 check rlDhcpClActionTable/rlDhcpClActionEntry indexed by rlDhcpClActionIfIndex to see rlDhcpClActionStatus and rlDhcpClActionHostName for the switch's DHCP client interface. If rlDhcpApprovalEnabled is set, pending leases appear in rlDhcpApprovalWaitingTable/rlDhcpApprovalWaitingEntry with rlDhcpApprovalWaitingAddress, rlDhcpApprovalWaitingMask, and rlDhcpApprovalWaitingGateway awaiting administrator approval. A lease stuck in the waiting table would reveal that the switch has requested an address but is not yet reachable via that new IP until approved.

What Can Be Monitored

DHCP client status per interface
assigned hostname
pending approval leases
waiting lease IP address/mask/gateway
DHCP approval enabled/disabled
