Description: Provides Cisco implementation of the IETF DHCP server MIB for monitoring DHCP address pools, bindings, and server statistics.

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 CISCO-IETF-DHCP-SERVER-MIB?

CISCO-IETF-DHCP-SERVER-MIB is Cisco's implementation of an IETF-style MIB for devices acting as BOOTP/DHCPv4 servers, covering address pool, binding, and protocol statistics (it excludes DDNS updates and the DHCP Failover protocol). It exposes counters for BOOTP requests/replies and drops, and DHCP message-type counters (DISCOVER, OFFER, REQUEST, DECLINE, ACK), alongside basic system identification objects. As a software-service-status MIB it lets an admin monitor whether the DHCP server process is actively handling client requests, and detect abnormal patterns such as rising decline or drop counts indicating address-pool exhaustion or misconfigured scopes. It is modeled on an IETF DHCP server MIB draft/standard, making it a Cisco-adapted variant of a broader IETF specification. It is deployed on Cisco routers and switches configured as local DHCP servers for connected subnets. Engineers can download the CISCO-IETF-DHCP-SERVER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-IETF-DHCP-SERVER-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

Cisco router/switch (DHCP server role)

Monitoring Examples

An admin can monitor cDhcpv4CountDiscovers versus cDhcpv4CountOffers and cDhcpv4CountAcks to see the DHCP handshake completion rate, and a large gap between discovers and acks suggests address-pool exhaustion or server overload. cBootpCountDropUnknownClients and cBootpCountDropNotServingSubnet reveal misconfigured relay agents or clients requesting addresses the server isn't authorized to serve. cDhcpv4CountDeclines rising over time can indicate address conflicts on the network, worth cross-checking with the address pool configuration.

What Can Be Monitored

BOOTP request/reply/drop counts
DHCP discover/offer/request/ack counts
DHCP decline counts
unknown-client and wrong-subnet drop counts

How to Use in IPNetwork Monitor

Example using cBootpCountRequests OID:

Select a Cisco router/switch (DHCP server role) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cBootpCountRequests into the Find box to locate it in the OID tree, then select it and click OK. The number of packets received that contain a Message Type of 1 (BOOTREQUEST) in the first octet and do not contain option number 53 (DHCP Message Type) in the options. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

While this object has a maximum size of 255 octets, a Fully-Qualified Domain Name (FQDN) consisting of a Host Name part and a Domain Name part is currently limited to 255 octets. Therefore, the sum of the string lengths for this object and the cDhcpv4ServerClientDomainName MUST be, in practice, less than 256 octets.
INT cDhcpv4ServerClientLeaseType	1.3.6.1.4.1.9.10.102.1.4.4.1.4	INTEGER	read-only	The type of this address. Types are: (1) Static addresses defined by the server configuration. (2) Dynamic addresses defined by the server configuration AND actually assigned by the server. (3) Expired dynamic addresses, previously assigned by the server, and 'remembered' for subsequent assignment to the same host. (4) Addresses reserved (i.e., not assignable) by the server configuration. (5) Addresses previously assigned by the server, but temporarily or permanently removed from assignable state for some reason, e.g., the server received an ICMP ECHOREPLY for the IPv4 address or a DHCPDECLINE message has been received for the IPv4 address.
cDhcpv4ServerClientObjects	1.3.6.1.4.1.9.10.102.2.2.9			Objects belonging to the cDhcpv4ServerClientObjects group.

The subnet, resulting from logically ANDing the subnet mask with the entry's IPv4 address, MUST be configured on this server and appear as a row in the cDhcpSubnetTable.
cDhcpv4ServerClientTable	1.3.6.1.4.1.9.10.102.1.4.4		not-accessible	An optional list of addresses that are known by this server. The list MUST contain addresses that have not expired. The list MUST NOT contain addresses that have never been assigned by the server UNLESS the lease is pre-configured in the server (e.g., a static lease for a host). Expired leases MAY appear during the time they are 'remembered' by the server for subsequent assignment to the same host.
U32 cDhcpv4ServerClientTimeRemaining	1.3.6.1.4.1.9.10.102.1.4.4.1.5	Unsigned32	read-only	The number of seconds until the lease expires. A value of 4294967295 (i.e., 0xFFFFFFFF) SHOULD be used for leases that have a lease time which is 'infinite' and for BOOTP leases.
NTF cDhcpv4ServerDuplicateAddress	1.3.6.1.4.1.9.10.102.0.2.0.5			This notification signifies that a duplicate IPv4 address has been detected. The DHCP server can detect this condition through the ping-before-offer mechanism. Alternatively, the client may have sent a DHCPDECLINE back to the server; this is assumed to be the result of the client detecting that the address was in use. In either case, the DHCP server marks the IPv4 address as unavailable for leasing to clients. The cDhcpv4ServerNotifyClientOrServerDetected object indicates whether the client or server detected this condition.
NTF cDhcpv4ServerFreeAddressHigh	1.3.6.1.4.1.9.10.102.0.2.0.2			This notification signifies that the number of available IPv4 addresses for a particular shared network has risen above the value of cDhcpv4ServerSharedNetFreeAddrHighThreshold for that shared network.

This object is set by the server to (1) if the client used DHCPDECLINE to mark the offered address as in-use, or to (2) if the server discovered the address in use by some client before offering it.
ADR cDhcpv4ServerNotifyDuplicateIpAddr	1.3.6.1.4.1.9.10.102.1.7.1	InetAddressIPv4	accessible-for-notify	The IPv4 address found to be a duplicate. Duplicates are detected by servers, which issue an ICMP ECHOREQUEST prior to offering an IPv4 address lease, or by a client issuing a gratuitous ARP message and reported through a DHCPDECLINE message.
ADR cDhcpv4ServerNotifyDuplicateMac	1.3.6.1.4.1.9.10.102.1.7.2	CDhcpv4PhysicalAddress	accessible-for-notify	The offending MAC address which caused a duplicate IPv4 address to be detected, if captured by the server, else 00-00- 00-00-00-00.

If a cDhcpv4ServerFreeAddressLow event was generated for this subnet, and the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold, then a cDhcpv4ServerFreeAddressHigh event will be generated. No more cDhcpv4ServerFreeAddressHigh events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses becomes equal to or less than the value of cDhcpv4ServerSubnetFreeAddrLowThreshold.
U32 cDhcpv4ServerSharedNetFreeAddrLowThreshold	1.3.6.1.4.1.9.10.102.1.4.1.1.2	Unsigned32	read-write	The low threshold for available free addresses in this shared network. If the value for available free addresses in this shared network becomes equal to or less than this value, a cDhcpv4ServerFreeAddressLow event is generated for this shared network. No more cDhcpv4ServerFreeAddressLow events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses has exceeded the value of cDhcpv4ServerSharedNetFreeAddrHighThreshold.

A shared network is the logical aggregation of one or more subnets that share a common network segment (e.g., multi- tapped coaxial cable, wiring hub, or switch). This table is present ONLY for those servers that organize the ranges of addresses available for assignment where a higher-level grouping (i.e., the 'shared' network) exists above ranges and subnets.
U32 cDhcpv4ServerSharedNetTotalAddresses	1.3.6.1.4.1.9.10.102.1.4.1.1.6	Unsigned32	read-only	The number of IPv4 addresses which are available within this shared network. If the server does not count total addresses by shared network segment, this value will be zero.
NTF cDhcpv4ServerStartTime	1.3.6.1.4.1.9.10.102.0.2.0.3			This notification signifies that the server of the specified type has started on the host from which this notification has been sent.
NTF cDhcpv4ServerStopTime	1.3.6.1.4.1.9.10.102.0.2.0.4			This notification signifies that the server of the specified type has stopped normally on the host from which this notification has been sent.
ADR cDhcpv4ServerSubnetAddress	1.3.6.1.4.1.9.10.102.1.4.2.1.1	InetAddressIPv4	not-accessible	The IPv4 address of the subnet entry in the cDhcpv4ServerSubnetTable.
cDhcpv4ServerSubnetEntry	1.3.6.1.4.1.9.10.102.1.4.2.1		not-accessible	A logical row in the cDhcpv4ServerSubnetTable.
U32 cDhcpv4ServerSubnetFreeAddresses	1.3.6.1.4.1.9.10.102.1.4.2.1.6	Unsigned32	read-only	The number of free IPv4 addresses which are available in this subnet.
U32 cDhcpv4ServerSubnetFreeAddrHighThreshold	1.3.6.1.4.1.9.10.102.1.4.2.1.5	Unsigned32	read-write	The high threshold for available free addresses in this subnet. If a cDhcpv4ServerSubnetFreeAddrLowThreshold event has been generated for this subnet, and the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold, then a cDhcpv4ServerFreeAddressHigh event will be generated. No more cDhcpv4ServerFreeAddressHigh events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses becomes equal to or less than the value of cDhcpv4ServerSubnetFreeAddrLowThreshold.
U32 cDhcpv4ServerSubnetFreeAddrLowThreshold	1.3.6.1.4.1.9.10.102.1.4.2.1.4	Unsigned32	read-write	The low threshold for available free addresses in this subnet. If the value for available free addresses in this subnet becomes equal to or less than this value, a cDhcpv4ServerSubnetFreeAddrLowThreshold event will be generated for this shared network. No more cDhcpv4ServerSubnetFreeAddrLowThreshold events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold.
ADR cDhcpv4ServerSubnetMask	1.3.6.1.4.1.9.10.102.1.4.2.1.2	InetAddressPrefixLength	read-only	The subnet mask of the subnet. This MUST be the same as the value of DHCP option 1 offered to clients on this subnet.
cDhcpv4ServerSubnetObjects	1.3.6.1.4.1.9.10.102.2.2.7			Objects belonging to the cDhcpv4ServerSubnetObjects group.
STR cDhcpv4ServerSubnetSharedNetworkName	1.3.6.1.4.1.9.10.102.1.4.2.1.3	SnmpAdminString	read-only	The shared subnet name (used as an index into the server shared subnet table) to which this subnet belongs. This value will be null for servers that do not organize or describe networks in this manner.
cDhcpv4ServerSubnetTable	1.3.6.1.4.1.9.10.102.1.4.2		not-accessible	A list of subnets that are configured in this server.
cDhcpv4SrvCompliance	1.3.6.1.4.1.9.10.102.2.1.1			This group describes the requirements for conformance to the DHCP Server MIB. A DHCPv4 server implementation is only required to support IPv4 addresses.
cDhcpv4SrvComplianceRev1	1.3.6.1.4.1.9.10.102.2.1.2			This group describes the requirements for conformance to the DHCP Server MIB. A DHCPv4 server implementation is only required to support IPv4 addresses.
cDhcpv4SrvCompliances	1.3.6.1.4.1.9.10.102.2.1
cDhcpv4SrvConfiguration	1.3.6.1.4.1.9.10.102.1.4			Objects that contain pre-configured and dynamic configuration information.

cDhcpv4SrvSystem	1.3.6.1.4.1.9.10.102.1.1			Group of objects that are related to the overall system.
STR cDhcpv4SrvSystemDescr	1.3.6.1.4.1.9.10.102.1.1.1	SnmpAdminString	read-only	A textual description of the server. This value should include the full name and version identification of the server.
OID cDhcpv4SrvSystemObjectID	1.3.6.1.4.1.9.10.102.1.1.2	OBJECT IDENTIFIER	read-only	The vendor's authoritative identification of the network management subsystem contained in this entity. This value is allocated within the SMI enterprise subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determining what kind of server is being managed. For example, if vendor Ohso Soft, Inc. is assigned the subtree 1.3.6.1.4.1.4242, it may assign the identifier 1.3.6.1.4.1.4242.1.1 to its Ursa DHCP Server.
cDhcpv4SrvSystemObjects	1.3.6.1.4.1.9.10.102.2.2.1			Objects belonging to the cDhcpv4SrvSystemObjects group.
ciscoIetfDhcpSrvMIB	1.3.6.1.4.1.9.10.102			The MIB module for entities implementing the server side of the Bootstrap Protocol (BOOTP) and the Dynamic Host Configuration protocol (DHCP) for Internet Protocol version 4(IPv4).
