Description: Provides extended DHCP relay configuration including Option 82 policies and relay statistics on H3C devices.

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 A3COM-HUAWEI-DHCPRELAY-MIB?

A3COM-HUAWEI-DHCPRELAY-MIB is a private MIB from the former 3Com-Huawei (H3C) joint venture for configuring the DHCP Relay Agent feature on H3C switches and routers. It exposes a per-interface relay-mode selection table and an IP-to-group mapping table that associates relay interfaces with configured DHCP server groups. As a configuration-focused MIB it lets an administrator confirm which interfaces have DHCP relay enabled and which upstream server group each is pointed at, rather than reporting live lease statistics. It is deployed on H3C access/aggregation switches acting as DHCP relay points between client VLANs and a centralized DHCP server. Engineers can download the A3COM-HUAWEI-DHCPRELAY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DHCPRELAY-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

H3C (Huawei-3Com) switches and routers

Monitoring Examples

An administrator walks h3cDHCPRIfSelectTable to confirm relay mode per interface, then cross-checks h3cDHCPRIpToGroupTable to verify which DHCP server group that interface forwards requests to.

What Can Be Monitored

per-interface DHCP relay mode

If the value of h3cDHCPROption82IfFormat is 'normal', the value is automatically set with 'invalid'. the value can not be set with 'invalid' by user. 'mac' indicates the option 82 verbose format is filled in with the mac of DHCP relay input interface. If the value of h3cDHCPROption82IfFormat is set with 'verbose', the value is automatically set with 'mac'. 'sysname' indicates the option 82 verbose format is filled in with the name of the DHCP relay. 'userdefine' indicates the option 82 verbose format is filled in with the string defined by user. If the value is set with 'userdefine', the value of h3cDHCPROption82IfUsrDefString must be set simultaneously.

If the value of h3cDHCPROption82IfFormat is 'normal', or the value of h3cDHCPROption82IfNodeType is 'mac' or 'sysname', it is set with a null string automatically and can not be modified by user. It must be set with a non-zero length string when the value of h3cDHCPROption82IfNodeType is set with 'userdefine'.
