Description: Manages DHCP snooping security on Cisco switches, controlling trusted/untrusted port assignments and binding table entries.

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-DHCP-SNOOPING-MIB?

CISCO-DHCP-SNOOPING-MIB is a Cisco private MIB for the DHCP Snooping Layer-2 security feature on Catalyst/IOS switches, which uses information gleaned from DHCP packets to enforce per-interface trust and validate address bindings. It exposes configuration data such as global feature enable state, per-VLAN snooping configuration, the binding database file location and update interval, relay agent information option handling, and MAC-address matching rules. Rather than hardware sensors, its monitoring value is in software/security-feature status: confirming the feature is actually enabled fleet-wide, checking the binding table against its configured maximum size limit, and watching binding-change notifications to catch anomalies like a DHCP starvation or spoofing attempt in progress. It works alongside Cisco's VLAN membership objects and standard SNMP notification infrastructure rather than a formal IETF MIB dependency. It is typically deployed on Cisco Catalyst switches in campus and enterprise access-layer networks to protect against rogue DHCP servers and IP/MAC spoofing, with a CISCO-DHCP-SNOOPING-MIB download commonly used to load the module into network monitoring tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-DHCP-SNOOPING-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 Catalyst switches
Cisco IOS/IOS-XE network switches

Monitoring Examples

An admin polls cdsFeatureEnable to confirm DHCP snooping is active, and walks cdsVlanConfigTable/cdsVlanConfigEntry (indexed by cdsVlanIndex) to verify snooping is enabled on the expected VLANs. cdsGlobalMaxBindingsLimit combined with cdsBindingsNotifEnabled lets an operator watch for a switch approaching its binding-table capacity, which can indicate a DHCP starvation attack. cdsDatabaseFile and cdsDatabaseUpdateInterval reveal whether the binding database is being persisted to flash and how frequently, important for surviving a switch reload without losing binding state.

What Can Be Monitored

DHCP snooping feature enable status
per-VLAN snooping configuration
binding database file and update interval
maximum binding table limit
relay agent information option settings
binding change notifications

How to Use in IPNetwork Monitor

Example using cdsTotalForwardedPkts OID:

Select a Cisco Catalyst/IOS-XE switch (DHCP snooping) 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 cdsTotalForwardedPkts into the Find box to locate it in the OID tree, then select it and click OK. Indicates the total number of packets subjected to DHCP Snooping is forwarded. 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 Counter64-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 (in packets), 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.

For each VLAN, if Source Guard feature is enabled then the bit corresponding to that VLAN is set to '1'. Note that if the length of this string is less than 256 octets, any 'missing' octets are assumed to contain the value zero. A NMS may omit any zero-valued octets from the end of this string in order to reduce SetPDU size, and the agent may also omit zero-valued trailing octets, to reduce the size of GetResponse PDUs.

For each VLAN, if Source Guard feature is enabled then the bit corresponding to that VLAN is set to '1'. Note that if the length of this string is less than 256 octets, any 'missing' octets are assumed to contain the value zero. A NMS may omit any zero-valued octets from the end of this string in order to reduce SetPDU size, and the agent may also omit zero-valued trailing octets, to reduce the size of GetResponse PDUs.
