Description: Manages Cisco Virtual Switching System (VSS) domain, switch member roles, and virtual switch link (VSL) status.

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 CISCO-VIRTUAL-SWITCH-MIB?

CISCO-VIRTUAL-SWITCH-MIB is a Cisco-proprietary MIB for managing the Virtual Switching System (VSS), a technology that combines two physical Cisco chassis into one logical switch, part of Cisco's data-center/campus switching product line. It exposes configuration and status data about the virtual switch domain, the role and capability of each member switch, the Virtual Switch Link (VSL) used to interconnect the core switches, and core-switch priority/preemption settings. This MIB is important for monitoring both hardware and software status: cvsSwitchMode and cvsSwitchConvertingStatus reveal whether a chassis is operating in standalone or virtual-switch mode or mid-conversion, cvsCoreSwitchConfigTable exposes each core switch's role/priority for determining which chassis is active, and VSL change notifications flag a critical link failure between the two chassis that could split the virtual switch. It is a Cisco enterprise MIB that builds on standard Cisco chassis/interface conventions and interacts closely with Cisco's redundancy/high-availability MIBs. It is typically deployed in Cisco Catalyst 6500/6800-series campus and data-center core switches configured in VSS mode for high availability. Network engineers researching cisco virtual switches reference this MIB to monitor Cisco Virtual Switching System (VSS) redundancy state via SNMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-VIRTUAL-SWITCH-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

  • Cisco Catalyst 6500/6800-series switches configured for Virtual Switching System (VSS)

Monitoring Examples

An administrator would poll cvsSwitchMode and cvsSwitchConvertingStatus to confirm both chassis are correctly operating as a converted virtual switch rather than stuck mid-conversion. cvsCoreSwitchConfigTable's cvsCoreSwitchPriority and cvsCoreSwitchPreempt would be checked to verify the intended active/standby priority ordering, and a cvsVSLChangeNotifEnable-driven trap firing would immediately flag a Virtual Switch Link failure between the two chassis, a critical event that risks a dual-active split-brain condition if not addressed quickly. cvsSwitchCapability helps confirm both switch members support the same VSS feature set before combining them into one domain.

What Can Be Monitored

  • virtual switch domain and mode
  • switch conversion status
  • core switch role and priority
  • VSL (Virtual Switch Link) status/change events
  • switch capability
  • preemption configuration

How to Use in IPNetwork Monitor

Example using cvsVSLTxTotalPkts OID:

Select a Cisco Catalyst 6500/6800-series switch (VSS) 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 cvsVSLTxTotalPkts 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. The total number of transmitted packets. 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 Counter32-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.
