Description: Manages DHCP server address pools and lease assignments on Bay Networks (Nortel) router platforms.

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 BayNetworks-DHCP-MIB?

BayNetworks-DHCP-MIB is a vendor-specific MIB from Bay Networks (later acquired by Nortel) used to manage the DHCP server functionality embedded in Bay/Nortel router platforms (the "wf" prefix reflects the legacy Wellfleet naming). It exposes configuration and operational data about DHCP address pools, server interfaces, and lease assignments handed out to clients on each interface. In a monitoring context it is used to check the software-level health and configuration status of the DHCP service running on the router, such as whether an interface's address pool is depleted or lease table entries are behaving as expected, rather than physical hardware sensors. It is a legacy, self-contained proprietary MIB with no strong dependency on other standard MIBs beyond basic SNMPv2 conventions. It would typically be deployed on older Bay Networks/Nortel routers or access concentrators acting as DHCP servers at a branch or campus edge, where BayNetworks-DHCP-MIB SNMP monitoring helps confirm address pools aren't running dry.

IPNetwork Monitor allows you to monitor SNMP objects defined in BayNetworks-DHCP-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

Bay Networks/Nortel router
Bay Networks/Nortel access concentrator

Monitoring Examples

An administrator would poll wfDhcpSvrIntfTable to see, per router interface, the configured DHCP address pool and current lease statistics, revealing when a pool is nearing exhaustion (a common cause of new clients failing to obtain addresses). Cross-referencing entries in this table against interface indexes lets an operator pinpoint exactly which LAN segment is running out of available addresses. This is a configuration/service-status check on the DHCP subsystem rather than a hardware health check.

What Can Be Monitored

DHCP address pool utilization per interface
DHCP lease assignments
DHCP server interface configuration

INT wfDhcpSvrDelete	1.3.6.1.4.1.18.3.5.3.24.1.1.1	INTEGER	read-write	Created/Deleted: if set to Deleted, the DHCP server is removed from this platform.
INT wfDhcpSvrDisable	1.3.6.1.4.1.18.3.5.3.24.1.1.2	INTEGER	read-write	Enable/Disable: controls whether the DHCP server is enabled or disabled on this platform.
IP wfDhcpSvrMgrIpAddr	1.3.6.1.4.1.18.3.5.3.24.1.1.3	IpAddress	read-write	IP Address of the NetID DHCP Server Manager serving this platform instance.
INT wfDhcpSvrMgrTcpPort	1.3.6.1.4.1.18.3.5.3.24.1.1.4	INTEGER	read-write	The remote TCP port number over which the DHCP Server communicates with the NetID DHCP Server Manager.
INT wfDhcpSvrConfDetPings	1.3.6.1.4.1.18.3.5.3.24.1.1.5	INTEGER	read-write	Number of ping attempts that should be made to a prospective client IP address to detect a possible conflict before declaring it unused and therefore available.
INT wfDhcpSvrIcmpTmo	1.3.6.1.4.1.18.3.5.3.24.1.1.6	INTEGER	read-write	Amount of time, in milliseconds, to wait for a conflict detection ping to time out.
INT wfDhcpSvrSafeModeDisable	1.3.6.1.4.1.18.3.5.3.24.1.1.7	INTEGER	read-write	Specifies whether the DHCP Server should wait until it gets acknowledgment of successful commitment of a lease from the NetID DHCP Server Manager before sending a lease-granted acknowledgment back to the DHCP Client. If set to Enabled, the DHCP Server will wait for the NetID DHCP Server Manager to confirm successful commit. If set to Disabled, the DHCP Server will immediately send back a lease-granted acknowledgement to the DHCP Client, without awaiting a commit-succeeded acknowledgment from the NetID DHCP Server Manager.
INT wfDhcpSvrMaxPendingLeases	1.3.6.1.4.1.18.3.5.3.24.1.1.8	INTEGER	read-write	Maximum number of lease requests to the DHCP Server which are pending commitment by the NetID DHCP Server Manager. Once there are wfDhcpSvrMaxPendingLeases lease requests pending, all new lease requests will be dropped until the number of requests pending decreases to wfDhcpSvrMaxPendingLeases/2.
INT wfDhcpSvrDebugLevel	1.3.6.1.4.1.18.3.5.3.24.1.1.9	INTEGER	read-write	Maximum debug level for optional debug messages from the DHCP Server. Normally, only messages with a debug level of 0 will be logged. The higher this attribute is made (up to a maximum of 10), the more messages will be logged. Since the logging of additional information can fill the log very rapidly and cause loss of other information, this attribute should only be changed to resolve critical problems.
