What Is CTRON-DLSW-MIB?

CTRON-DLSW-MIB is a Cabletron (Enterasys) enterprise MIB that manages Data Link Switching (DLSw), a protocol that tunnels legacy SNA and NetBIOS traffic over an IP network, typically to let older mainframe or LAN-based applications communicate across modern routed networks. It exposes configuration objects for DLSw peer connections and virtual ring numbers, along with operational status and uptime for the DLSw process itself. For software status monitoring, ctdlswAdminStatus and ctdlswOperStatus reveal whether the DLSw service is administratively enabled and actually running, while ctdlswUpTime tracks how long that DLSw process has been up, useful for spotting unexpected restarts. It builds on the standard DLSw architecture (RFC 1795/2166) and is used alongside device interface and port MIBs, since DLSw runs over specific physical/logical ports. It is deployed on Cabletron/Enterasys routers or switches acting as DLSw peers bridging legacy SNA/NetBIOS traffic between remote sites over an IP WAN, and a CTRON-DLSW-MIB download is typically obtained from Enterasys/Extreme Networks archives to load into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-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

Cabletron/Enterasys router or switch running DLSw

Monitoring Examples

An administrator would poll ctdlswAdminStatus and ctdlswOperStatus to confirm the DLSw process is enabled and actually operational, and check ctdlswUpTime to see if the service has recently restarted unexpectedly. Walking ctdlswPortTable entries (via ctdlswPort/ctdlswNode objects) shows which ports and DLSw peer nodes are configured and their per-node connection state. A mismatch between an enabled ctdlswAdminStatus and a down ctdlswOperStatus on a given port would flag a failed DLSw peer connection needing investigation.

What Can Be Monitored

DLSw admin/operational status
DLSw process uptime
DLSw port table entries

OID symbolic	OID numeric	Type	Access	Description
INT ctdlswAcceptDynamicTConn	1.3.6.1.4.1.52.4.1.2.8.1.1.10	INTEGER	read-write	Specifies whether this DLSw allows unconfigured DLSw partners to establish transport connections. Yes(1) means unconfigured DLSw partners may establish transport connections with this DLSw. No(2) means only user configured DLSw partners may establish transport connections with this DLSw.
INT ctdlswAdminStatus	1.3.6.1.4.1.52.4.1.2.8.1.1.2	INTEGER	read-write	Sets the system-wide administrative state of DLSw services.
INT ctdlswDefaultPortNumber	1.3.6.1.4.1.52.4.1.2.8.1.1.11	INTEGER	read-write	Specifies the index of the port whose associated IP address will be used to identify this DLSw node to its DLSw partners. The value must be consistent with 'ifIndex' of mib-II.

INT ctdlswEventAdminStatus	1.3.6.1.4.1.52.4.1.2.8.6.1.1	INTEGER	read-write	Set the administrative state of Data Link Switching event logging. enabled(3) causes the event log to become active. disabled(2) causes the event log to become inactive.
ctdlswEventEntry	1.3.6.1.4.1.52.4.1.2.8.6.3.1.1		not-accessible	Each entry specifies events that have been logged.
ctdlswEventFilterEntry	1.3.6.1.4.1.52.4.1.2.8.6.2.1.1		not-accessible	Each entry specifies the filter for log entries. The instance ctdlswEventProtocol refers to the instance used in the nwRtgProtocolTable and nwComponentTable specified by the ctrouter-mib.txt.
ctdlswEventFilterTable	1.3.6.1.4.1.52.4.1.2.8.6.2.1		not-accessible	This table contains descriptions of how to filter log entries.
INT ctdlswEventFltrAction	1.3.6.1.4.1.52.4.1.2.8.6.2.1.1.6	INTEGER	read-write	This field specifies how the events are to be logged. Specifying log(1) stores the events in the event log table (defined below). Specifying trap(2) sends events out through the trap mechanism. Specifying logTrap(3) does both.
INT ctdlswEventFltrControl	1.3.6.1.4.1.52.4.1.2.8.6.2.1.1.3	INTEGER	read-write	Setting this field to delete will allow entries to be removed from the table. This is done by adding new entries with instance fields that match the entry to be removed from the table. The new entry being added must have this control field set to delete in order for the matching entry already in the table to be deleted. Setting this field to add will add the entry to the table.
INT ctdlswEventFltrIfNum	1.3.6.1.4.1.52.4.1.2.8.6.2.1.1.2	INTEGER	read-only	Specifies the port on which to log events.
