Description: Juniper Networks MIB for monitoring Virtual Chassis configurations, member roles, and interconnect status on Juniper EX 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 JUNIPER-VIRTUALCHASSIS-MIB?

This Juniper enterprise MIB covers the Virtual Chassis feature, which interconnects multiple EX-Series switches via dedicated high-speed stacking ports so they operate and are managed as a single logical switch element. It exposes data about virtual chassis membership: member switch roles (master/backup/linecard), member identifiers, and stacking/interconnect port status. Monitoring emphasis is primarily on hardware/topology status — tracking which member holds the master or backup role and whether stacking interconnects are up is critical to detecting a split virtual chassis or a failed member, a direct hardware-health and high-availability concern. It builds on Juniper's chassis/FPC hierarchy MIBs since each virtual chassis member is itself a physical EX switch with its own chassis components. It is deployed on stacks of Juniper EX-Series switches configured as a Virtual Chassis in wiring-closet or aggregation-layer environments needing single-point management of multiple physical switches, and administrators can download the JUNIPER-VIRTUALCHASSIS-MIB file to load it into their MIB browser for stack monitoring.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-VIRTUALCHASSIS-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

Juniper EX Series switch (Virtual Chassis stack)

Monitoring Examples

No object or table names were provided in the input data for this module. Conceptually, based on its description, monitoring would involve a per-member table tracking role (master/backup/linecard), member ID, and stacking-port link status, polled to detect a member losing its interconnect link or an unexpected mastership change. Exact object names cannot be confirmed without the MIB source.

What Can Be Monitored

virtual chassis member role (master/backup/linecard)
stacking/interconnect port status
member switch presence/removal
mastership changes

How to Use in IPNetwork Monitor

Example using jnxVirtualChassisPortInPkts OID:

Select a Juniper EX Series switch (Virtual Chassis stack) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type jnxVirtualChassisPortInPkts into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. Indicates the total number of packets received on the virtual-chassis port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
jnxVirtualChassisMemberMIB	1.3.6.1.4.1.2636.3.40.1.4.1			The MIB modules for Virtual Chassis Member.Virtual Chassis Member feature allows a set of EX-Series switches to be connected together to form a Virtual Chassis. A virtual chassis will give all the features of a real chassis, potentially at a much lower cost points. A virtual chassis will be managed as a single box and will appear as a single network element to other switches and routers in the network. Some EX-Series switches will have the special high speed stacking ports which are used to connect to each other to form a stack. The EX-Series switches can also be connected by the 10GE (or 1GE) network ports to form a stack. These can be used by EX-Series switches that don't have dedicated stacking ports. Up to a maximum of 10 boxes can be stacked together.
