Description: Manages Layer 2 port isolation groups to restrict intra-VLAN communication between ports on H3C 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 HH3C-L2ISOLATE-MIB?
HH3C-L2ISOLATE-MIB is a Hangzhou H3C Technologies proprietary MIB implementing Layer 2 port isolation within a VLAN, blocking direct communication between isolated ports. Its objects cover a per-VLAN isolation-enable table and a permitted-MAC table (MAC address, row status) allowing specific MAC addresses to bypass isolation. As a configuration/security MIB it lets an administrator confirm which VLANs have Layer 2 isolation enabled and which MAC addresses are exempted. It is deployed on Hangzhou H3C Technologies switches. Engineers can download the HH3C-L2ISOLATE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-L2ISOLATE-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
- Hangzhou H3C Technologies switches
Monitoring Examples
An administrator checks hh3cL2IsolateEnable and hh3cL2IsoLatePermitMACTable to confirm Layer 2 isolation and its MAC exemptions on an H3C switch VLAN.
What Can Be Monitored
- Layer 2 port-isolation configuration and MAC exemptions
