Description: Huawei LAN switch DHCP MIB for managing DHCP snooping, DHCP relay, and IP-MAC-port binding tables on Huawei Layer 2/3 switches.
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 HUAWEI-LswDHCP-MIB?
HUAWEI-LswDHCP-MIB manages DHCP-related security and relay features on Huawei Layer 2/3 LAN switches, specifically DHCP snooping, DHCP relay, and IP-MAC-port binding table management. It exposes configuration objects for enabling DHCP snooping/relay per VLAN or port and status/table objects reporting the learned IP-MAC-port bindings used to prevent IP spoofing and rogue DHCP servers. Its monitoring focus is on software/security-feature state rather than physical hardware: administrators track the DHCP snooping binding table to verify legitimate host bindings are being learned correctly and to detect binding table anomalies that could indicate spoofing attempts or a misbehaving DHCP relay. It is a Huawei-private module conceptually related to the DHCP protocol standard but does not depend on a specific IETF DHCP MIB. It is deployed on Huawei access-layer switches in campus and enterprise networks as part of a Layer 2 security/access-control feature set. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-LswDHCP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-LswDHCP-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
- Huawei Layer 2/3 access switches
- Huawei S-series/Quidway switches (DHCP snooping/relay feature)
Monitoring Examples
An administrator would poll the IP-MAC-port binding table to confirm that hosts on access ports have valid, expected DHCP-snooping-learned bindings, and would check DHCP relay configuration objects to confirm requests are being forwarded to the correct DHCP server. An unexpected or duplicate binding entry for a given MAC or IP address could indicate an IP-spoofing attempt or a rogue device on the network. No concrete sample object names were available in the source data for this MIB.
What Can Be Monitored
- DHCP snooping binding table entries
- DHCP relay configuration status
- DHCP snooping enable state per VLAN/port
