MARVELL-TrafficSegmentation-MIB

Description: Marvell Semiconductor traffic segmentation MIB defining port-based private VLAN and traffic isolation configuration objects.

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.

MARVELL-TrafficSegmentation-MIB is a Marvell Semiconductor SNMP MIB for switches built on Marvell switching silicon, defining port-based traffic segmentation (private-VLAN-like isolation) configuration objects. It exposes a configuration table (rlTrafficSegConfigTable) defining, per segmentation group, the set of allowed ingress and egress ports, and a corresponding per-port table (rlTrafficSegTable) recording each port's actual configured ingress/egress port membership and row status. Because this MIB is primarily a configuration/policy MIB rather than a runtime counters MIB, its main monitoring value is confirming that traffic-isolation policy is correctly and consistently applied - verifying rlTrafficSegConfigRowStatus/rlTrafficSegRowStatus are active and that ingress/egress port sets match intended segmentation, a software-configuration correctness check rather than a hardware health check. It has no explicit cross-MIB dependency shown, functioning as a self-contained Marvell chipset-level configuration extension similar in spirit to standard VLAN/private-VLAN MIBs. It is deployed on enterprise/SMB switches using Marvell switching ASICs where administrators need to isolate groups of ports from each other for security (e.g. guest networks, multi-tenant environments) without full VLAN segmentation. Engineers can download the MARVELL-TrafficSegmentation-MIB file directly to load it into their MIB browser.

An administrator would walk rlTrafficSegConfigTable/rlTrafficSegConfigEntry by rlTrafficSegConfigIndex to confirm which ingress and egress ports are permitted in each segmentation group, then cross-check the per-port rlTrafficSegTable to verify a specific port's rlTrafficSegIngressPorts/rlTrafficSegEgressPorts match the intended policy. An unexpected rlTrafficSegRowStatus value on a port would reveal that a segmentation rule failed to apply, potentially exposing traffic that should have been isolated.

Manages Marvell switch traffic segmentation configuration for ingress/egress port control and traffic isolation.
