Description: Eltex MES L2 tunnel configuration MIB for managing Layer 2 protocol tunneling and encapsulation on MES platforms.

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 ELTEX-MES-L2-TUNNEL-CONFIG-MIB?

This is an Eltex private MIB for the MES series of Ethernet switches, covering Layer 2 protocol tunneling configuration that lets separate customer networks appear as a single VLAN across a service-provider link. It exposes configuration data for tunneled protocol types, tunnel destination MAC address, and CoS marking, alongside threshold and statistics objects for tunnel traffic. Beyond pure configuration, the threshold and statistics tables support monitoring the software/traffic-health status of the L2 tunneling feature, revealing when tunneled protocol traffic is being dropped or has triggered a protective shutdown due to exceeding configured limits. As a vendor-private feature MIB it builds on standard Ethernet/VLAN and SNMP notification conventions rather than a specific external MIB dependency. It is typically deployed in service-provider or campus networks using Eltex MES switches to tunnel protocols like STP or CDP transparently between customer sites. Engineers can download the ELTEX-MES-L2-TUNNEL-CONFIG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ELTEX-MES-L2-TUNNEL-CONFIG-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

An administrator checks eltLtcTunneledProtocolTable / eltLtcTunneledProtocolEntry for the configured eltLtcTunneledProtocolType and eltLtcTunnelCos, then monitors eltLtcTunnelThresholdTable entries (eltLtcTunnelDropThreshold, eltLtcTunnelShutdownThreshold) alongside eltLtcTunnelStatisticsTable counters to see current tunneled-frame rates. If tunnel statistics approach the eltLtcTunnelDropThreshold or an eltLtcNotificationEnable-triggered trap fires, it indicates a tunneled protocol storm risking port shutdown.

What Can Be Monitored

tunneled protocol type per port
tunnel CoS marking
tunnel drop threshold
tunnel shutdown threshold
tunnel traffic statistics

OIDs

OID symbolic	OID numeric	Type	Access	Description
eltMesL2TunnelConfig	1.3.6.1.4.1.35265.1.23.13			This MIB module is for layer 2 tunneling related configurations on a device. Tunneling allows separate local networks to be considered as a single VLAN. These separate networks are connected via an ISP, which will tunnel the packets from one network to another, making it appear as if the two networks are actually just one.
eltMesLtcMIBObjects	1.3.6.1.4.1.35265.1.23.13.1
eltMesLtcGlobal	1.3.6.1.4.1.35265.1.23.13.1.1
T/F eltLtcNotificationEnable	1.3.6.1.4.1.35265.1.23.13.1.1.1	TruthValue	read-write	This object indicates whether the system will generate the eltLtcTunnelDropThresholdExceeded and eltLtcTunnelShutdownThresholdExceeded notifications.
MAC eltLtcTunnelMacAddress	1.3.6.1.4.1.35265.1.23.13.1.1.2	MacAddress	read-write	The destination MAC address that replaces the original destination MAC address of tunneled frames.
eltMesLtcTunneledProtocol	1.3.6.1.4.1.35265.1.23.13.1.2
eltLtcTunneledProtocolTable	1.3.6.1.4.1.35265.1.23.13.1.2.1		not-accessible	This table contains information about the protocols being tunneled. Only tunneled protocol filtering capable interfaces are shown.
eltLtcTunneledProtocolEntry	1.3.6.1.4.1.35265.1.23.13.1.2.1.1		not-accessible	Information about the protocols being tunneled. Only tunneled protocol filtering capable interfaces are shown.
BIT eltLtcTunneledProtocolType	1.3.6.1.4.1.35265.1.23.13.1.2.1.1.1	Bits	read-write	Indicates tunneled protocol of the interface. If a BIT is set, then the value of the corresponding protocol is tunneled. Specifically, if the 'stp(0)' BIT is set, then the Spanning Tree Protocol PDU is tunneled. At this moment, there are no other supported protocols. If the bit for a given protocol is set for an interface, then the statistics for that interface and protocol will start to be monitored.
QOS eltLtcTunnelCos	1.3.6.1.4.1.35265.1.23.13.1.2.1.1.2	QosLayer2Cos	read-write	Specifies the user priority of the tunneled PDUs for the interface.
eltMesLtcTunnelThreshold	1.3.6.1.4.1.35265.1.23.13.1.3
eltLtcTunnelThresholdTable	1.3.6.1.4.1.35265.1.23.13.1.3.1		not-accessible	This table contains information about the thresholds for protocol tunneling. Only tunneled protocol filtering capable interfaces are shown. The objects will be on a per interface, per protocol basis.
eltLtcTunnelThresholdEntry	1.3.6.1.4.1.35265.1.23.13.1.3.1.1		not-accessible	Information about the thresholds for protocol tunneling. Only tunneled protocol filtering capable interfaces are shown. The entries will be on a per interface, per protocol basis

After reaching this drop threshold, the interface will start dropping PDUs for the given protocol. This value cannot be greater than the value of eltLtcTunnelShutdownThreshold. A value of 0 indicates that no limit is set.
U32 eltLtcTunnelShutdownThreshold	1.3.6.1.4.1.35265.1.23.13.1.3.1.1.3	Unsigned32	read-write	The shutdown threshold on an interface for a given protocol. After reaching the shutdown threshold, the interface will shutdown for the given protocol. This value cannot be less than the value of eltLtcTunnelDropThreshold. A value of 0 indicates that no limit is set.
