Description: Manages CSNA (Cisco SNA) functions on the Cisco Channel Interface Processor, enabling SNA protocol support over IP networks.

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-CIPCSNA-MIB?

CISCO-CIPCSNA-MIB manages the Cisco SNA (Systems Network Architecture) support feature, known as CIP-SNA, running on Cisco Mainframe Channel Connection (CMCC) cards that connect Cisco routers to IBM mainframe channels. The data it exposes covers per-card SNA administrative configuration (path, device, block-delay timing and length, maximum block length) as well as operational status such as card operating state and a slow-down condition indicating channel congestion. As a hardware/software status MIB it lets an administrator confirm a CMCC card's SNA feature is operationally up and detect when it has entered a slow-down state, which signals the card is throttling to protect against channel or session overload. It is specific to Cisco's CIP/CMCC hardware and channel-attached mainframe integration and does not depend on general IETF interface MIBs beyond basic card/interface identification. It is typically deployed in enterprise data centers bridging legacy IBM mainframe SNA traffic over Cisco IP/channel infrastructure. Engineers can download the CISCO-CIPCSNA-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CIPCSNA-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 router with Channel Interface Processor (CIP) / Mainframe Channel Connection (CMCC) card

Monitoring Examples

An administrator walks cipCardCsnaAdminTable / cipCardCsnaAdminEntry to review configured cipCardCsnaAdminPath, cipCardCsnaAdminDevice, and cipCardCsnaAdminMaxBlockLength settings for a channel path, then cross-references cipCardCsnaOperTable / cipCardCsnaOperEntry to check cipCardCsnaOperState for that same path. If cipCardCsnaOperSlowDownState shows the card has entered a slowdown condition, this indicates the CMCC card is being overwhelmed by SNA session traffic and may require block-delay tuning via cipCardCsnaAdminBlockDelayTime and cipCardCsnaAdminBlockDelayLength. Confirming cipCardCsnaAdminRowStatus is active ensures the administrative configuration is actually in effect on the card.

What Can Be Monitored

  • SNA card operational state
  • channel slow-down/congestion condition
  • block delay time and length
  • maximum block length configuration

How to Use in IPNetwork Monitor

Example using cipCardCsnaStatsBlocksTxd OID:

Select a Cisco router 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 cipCardCsnaStatsBlocksTxd 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 number of Blocks Transmitted. 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.
