Description: Manages Terminal Server stack configuration providing port grouping and session management for async terminal servers.

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-TS-STACK-MIB?

CISCO-TS-STACK-MIB is a Cisco MIB for managing a stack of Terminal Server (TS) units, providing configuration and control for grouping ports and coordinating firmware distribution across stacked async terminal servers. It exposes IP addressing (address, netmask, default gateway) for the stack management interface, stack membership/status information, and TFTP-based firmware download configuration and status. For hardware/software status monitoring, ciscoTsStackStatus reports the operational state of the stack, ciscoTsNumSwitches reports how many units are present, and ciscoTsTftpDownloadStatus reports the progress/result of a firmware download — directly reflecting software version rollout status across the stack. Interestingly, one described object references the Token Ring Bridge Relay Facility (TrBRF), suggesting the terminal server stack also participates in Token Ring bridging, tying it to Cisco's Token Ring MIB conventions. It is deployed in legacy dial-in/console-access environments where stacks of Cisco terminal servers provide async port aggregation. Engineers can download the CISCO-TS-STACK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-TS-STACK-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 stackable terminal server (async port aggregation)

Monitoring Examples

An administrator would poll ciscoTsStackStatus and ciscoTsNumSwitches to confirm all expected units in a terminal server stack are present and healthy, and check ciscoTsIpAddr/ciscoTsDefaultGateway for stack management connectivity. When pushing a firmware update, ciscoTsTftpServer and ciscoTsTftpFileLoc configure the source, ciscoTsTftpDownload triggers it, and ciscoTsTftpDownloadStatus is polled to confirm success or reveal a failed download (e.g., due to an unreachable TFTP server). ciscoTsTftpServerTrBRF ties the download source to a specific Token Ring Bridge Relay Facility path where relevant.

What Can Be Monitored

  • stack status/membership
  • number of stacked switches
  • management IP configuration
  • TFTP firmware download status
  • system current time
