Description: HH3C MIB for SNA Data Link Switching (DLSw) configuration and session management on H3C routers.

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-MIB?

HH3C-SNA-DLSW-MIB is an H3C (Huawei-3Com) private MIB for configuring and monitoring SNA Data Link Switching (DLSw), a protocol that tunnels legacy IBM SNA/NetBIOS traffic over IP/TCP networks, on H3C routers. It exposes DLSw node-level configuration (vendor ID, version, local address, priority, pacing/window parameters, keepalive interval) and status objects, plus transport connection (TConn) and bridge-group related tables for managing DLSw peer sessions. Its monitoring role centers on protocol/software status: checking hh3cdlswNodeStatus confirms whether the DLSw node/process is operational, while pacing, window, and keepalive parameters help diagnose session performance or stability issues with tunneled SNA traffic. It implements concepts from the IETF DLSw standard (RFC 1795) layered onto H3C's private enterprise MIB tree. It is deployed on H3C routers that provide legacy SNA/mainframe connectivity tunneling for enterprises maintaining older IBM systems. Engineers can download the HH3C-SNA-DLSW-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-SNA-DLSW-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 (Huawei-3Com) routers

Monitoring Examples

Polling hh3cdlswNodeStatus reveals whether the DLSw node process is up and running, while hh3cdlswNodeKeepAlive and hh3cdlswNodeMaxWindow/hh3cdlswNodeInitWindow expose the keepalive interval and windowing parameters that affect tunnel session stability under load. hh3cdlswTConn tracks the underlying transport connections carrying DLSw traffic, and hh3cdlswBridgeGroup relates DLSw sessions to the bridge groups forwarding the tunneled SNA/NetBIOS frames, letting an admin correlate a dropped mainframe session with a failed transport connection.

What Can Be Monitored

  • DLSw node operational status
  • keepalive interval
  • pacing/window configuration
  • transport connection (TConn) status
  • bridge group association

How to Use in IPNetwork Monitor

Example using hh3cdlswRemotePeerRecvPacks OID:

Select an H3C router (SNA Data Link Switching over IP) 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 hh3cdlswRemotePeerRecvPacks 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.
