Description: Manages Raisecom switch trunk link aggregation groups, member ports, and LAG load balancing.

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 SWITCH-TRUNK-MIB?

SWITCH-TRUNK-MIB is a Raisecom module (part of the same "rc" enterprise MIB family as SWITCH-IFEXTEND-MIB and SWITCH-RATELIMIT-MIB) managing link-aggregation (trunk/LAG) groups on Raisecom switches. Based on its stated purpose, it exposes trunk group definitions, member-port assignments, and load-balancing configuration for aggregated links. Its monitoring emphasis is software/configuration status of link aggregation - confirming which ports are aggregated into a given trunk and that the group is operating with its intended member set, since a lost or removed member link reduces available trunk bandwidth without necessarily taking the trunk itself down. It builds on IEEE 802.3ad/802.1AX link-aggregation concepts and standard interface indexing (IF-MIB ifIndex) for identifying member ports. It is deployed on Raisecom access/aggregation switches that use link aggregation for uplink resiliency and additional bandwidth. Engineers can download the SWITCH-TRUNK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SWITCH-TRUNK-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.

Monitoring Examples

No concrete object or table names were provided for this module in the source excerpt, so specific identifiers can't be cited. Based on its stated purpose, an operator would poll trunk-group membership and load-balancing configuration to confirm all expected member ports remain part of the aggregation. A member port dropping out of the trunk's active set would reduce available bandwidth and could go unnoticed without checking this MIB, since the remaining links would keep the logical trunk interface up.

What Can Be Monitored

trunk/LAG group membership
member port list

OIDs

OID symbolic	OID numeric	Type	Access	Description
rcTrunk	1.3.6.1.4.1.8886.6.1.6			The MIB module for managing trunk in rc2026.
ENA rcTrunkEnable	1.3.6.1.4.1.8886.6.1.6.1	EnableVar	read-write	Enable or disable trunking.
INT rcTrunkLoadingSharingMode	1.3.6.1.4.1.8886.6.1.6.2	INTEGER	read-write	The Rule to be applied to this Link Aggregator's Trunk Group Table. The rules are based on the following selections SrcMAC (1), means that the last three bits of the Source MAC Address are used to index the Trunk Group to get the destination port. DestMAC (2), means the last three bits of the Destination MAC Address are used to index into the Trunk Group to get the destination port. SrcXORDestMAC (3), means that the last three bits of the Source MAC Address are logically XORed with the last three bits of the Destination MAC Address and used to index into the Trunk Group to get the destination port. SrcIP (4), means the last three bits of the Source IP Address are used to index into the Trunk Group to get the destination port. DestIP (5), means the last three bits of the Destination IP Address are used to index into the Trunk Group to get the destination port. SrcXORDestIP (6), means the last three bits of the Source IP Address are logically XORed with the last three bits of the Destination IP Address and used to index into the Trunk Group to get the destination port. This rule defines the distribution algorithm applied to the aggregated link.
INT rcTrunkMaxGroup	1.3.6.1.4.1.8886.6.1.6.3	INTEGER	read-only	The number of maximum trunking group that system supports.
INT rcTrunkTicketGenerationAlgorithm	1.3.6.1.4.1.8886.6.1.6.4	INTEGER	read-write	There are two algorithm to generate trunk ticket: direct-map and crc. Direct-map uses the last two bits of mac address as the trunk ticket; Crc uses crc algorithm on all mac address to generate trunk ticket.
rcTrunkGroupTable	1.3.6.1.4.1.8886.6.1.6.5		not-accessible	Some ports participate in a trunking group. The range of group ID is 1-8.
rcTrunkGroupEntry	1.3.6.1.4.1.8886.6.1.6.5.1		not-accessible	The entry is used to set some ports into a trunking group.
INT rcTrunkGroupID	1.3.6.1.4.1.8886.6.1.6.5.1.1	INTEGER	not-accessible	The trunking group ID.
POR rcTrunkGroupSetPorts	1.3.6.1.4.1.8886.6.1.6.5.1.2	PortList	read-write	When a bit of PortList is set, the port this bit specified participate in a appointed trunking group.
POR rcTrunkGroupCurrentPortInOperation	1.3.6.1.4.1.8886.6.1.6.5.1.3	PortList	read-only	Show these ports that are in 'up' status in a trunking group.
INT rcTrunkGroupMode	1.3.6.1.4.1.8886.6.1.6.5.1.4	INTEGER	read-write	Trunking group support two mode, manual and static lacp mode.
