Description: HH3C extension MIB for SNA Data Link Switching (DLSw) providing vendor-specific DLSw management objects.

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 HH3C-SNA-DLSW-EXT-MIB?

HH3C-SNA-DLSW-EXT-MIB is an H3C (Hangzhou Huawei-3Com/New H3C) enterprise MIB extending standard Data Link Switching (DLSw) management with vendor-specific configuration objects for SNA-over-IP transport. It exposes per-node configuration data such as vendor ID, local IP address, priority, pacing window sizes, keepalive interval, and various connection/pending timeouts governing DLSw peer behavior. Its monitoring value lies mainly in software/protocol configuration and connection-state tuning rather than hardware sensors, letting an administrator verify DLSw peer timers and pacing settings that affect SNA session reliability over the WAN. It explicitly depends on and extends the standard DLSw protocol defined in RFC 1795, RFC 2024, and RFC 2166, layering H3C-specific enhancements on top of that IETF baseline. It is typically deployed on H3C routers providing legacy SNA/mainframe traffic encapsulation (DLSw) across a modern IP WAN, and network engineers can download the HH3C-SNA-DLSW-EXT-MIB file to load it into their MIB browser for reference.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-SNA-DLSW-EXT-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

  • H3C router providing SNA/DLSw over IP

Monitoring Examples

An administrator would check hh3cdeNodeKeepAliveInterval and hh3cdeNodeConnTimeout to diagnose why a DLSw peer connection is dropping or failing to establish reliably. hh3cdeNodeInitPacingWindow and hh3cdeNodeMaxPacingWindow would be reviewed when SNA sessions experience throughput problems, since pacing window mismatches between DLSw peers can throttle data flow. hh3cdeNodeLocalAddr and hh3cdeNodePriority help confirm which local node identity and priority are advertised in DLSw peer negotiation.

What Can Be Monitored

  • DLSw peer keepalive interval
  • connection timeout settings
  • pacing window sizes
  • node priority
  • local IP address configuration

How to Use in IPNetwork Monitor

Example using hh3cdeTConnOperRecvPkts OID:

Select an H3C router providing SNA/DLSw over IP (extended config) 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 hh3cdeTConnOperRecvPkts 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 Switch-to-Switch Protocol (SSP) messages received on this tcp transport connection. 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.
