What Is ZYXEL-MLD-SNOOPING-PROXY-MIB?
ZYXEL-MLD-SNOOPING-PROXY-MIB is a ZyXEL private enterprise MIB for Multicast Listener Discovery (MLD) snooping proxy, an IPv6 multicast optimization feature, placing it in the switching/IPv6 multicast configuration category. It exposes configuration for enabling MLD snooping proxy on VLANs/ports and the resulting group-membership state the switch has learned from downstream hosts, rather than hardware health indicators. Its monitoring value is mainly software-feature-state: confirming the proxy is enabled where expected and that it has correctly learned active multicast group memberships, which helps diagnose IPv6 multicast video/streaming delivery problems at the access layer. It depends on the IPv6 MLD protocol standard and interacts with the switch's VLAN and bridge MIBs for the ports/VLANs it operates on. It is typically deployed on ZyXEL access switches serving IPTV or other IPv6 multicast subscriber services where efficient multicast forwarding to only interested ports is required, and administrators of these switches typically start with a ZYXEL-MLD-SNOOPING-PROXY-MIB download to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-MLD-SNOOPING-PROXY-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
- ZyXEL managed Ethernet switch
Monitoring Examples
An operator would check whether MLD snooping proxy is enabled on the VLAN carrying an IPv6 multicast video service, then inspect the learned multicast group membership associated with subscriber ports to confirm hosts requesting a channel are correctly tracked. If a subscriber reports no video but the port isn't listed as a member of the expected multicast group, that points to a snooping/proxy learning failure rather than an upstream network issue. As no sample objects were provided for this MIB, exact table names cannot be confirmed, but the functional monitoring goal is proxy enable-state and group-membership visibility.
What Can Be Monitored
- MLD snooping proxy enabled state per VLAN
- learned multicast group memberships
- subscriber port multicast association
