Description: Manages Dasan switch port, VLAN, trunk, and forwarding configuration 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 DASAN-SWITCH-MIB?

DASAN-SWITCH-MIB is a vendor-specific MIB from Dasan Networks (Dasan Zhone) covering the configuration and operational management of its Ethernet switch product line, including port, VLAN, trunk/link-aggregation, and forwarding-table objects. It exposes configuration-oriented data (port settings, VLAN membership, trunk grouping) alongside operational state reflecting the switch's current forwarding behavior. In monitoring terms it is used primarily to check the software/configuration status of the switch, such as which VLANs and trunks are active and how ports are currently forwarding traffic, complementing standard IF-MIB interface counters. It typically works alongside the standard IETF BRIDGE-MIB and IF-MIB for interface- and bridging-level detail this vendor MIB does not duplicate. It is deployed on Dasan managed Ethernet switches in enterprise and carrier-access network environments. Administrators unfamiliar with this vendor module often start by loading it into a DASAN-SWITCH-MIB MIB Browser session to explore the VLAN, trunk, and forwarding-table objects before scripting automated polling.

IPNetwork Monitor allows you to monitor SNMP objects defined in DASAN-SWITCH-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

  • Dasan Networks (Dasan Zhone) managed Ethernet switches

Monitoring Examples

An operator would poll the switch's VLAN membership and trunk group tables to confirm a given port is assigned to the expected VLAN and trunk, and cross-check forwarding table entries against expected MAC-to-port mappings. A port unexpectedly missing from its configured VLAN, or a trunk group reporting an inactive member, would indicate misconfiguration or link failure. Because no concrete object names were available for this module, this description is necessarily generic rather than citing specific table/object identifiers.

What Can Be Monitored

  • port VLAN membership
  • trunk/link-aggregation group status
  • forwarding table entries
  • port configuration state

How to Use in IPNetwork Monitor

Example using dsCpuLoad10m OID:

Select a Dasan Networks (Dasan Zhone) managed Ethernet switch 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 dsCpuLoad10m into the Find box to locate it in the OID tree, then select it and click OK. It reports the switch's average CPU load over the last 10 minutes, as a percentage. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if CPU load exceeds 85%, a common warning threshold before sustained high load affects switching performance. Click Finish to create the monitor; you can adjust any parameter later.

FAQ

How can I verify which VLANs and trunk groups are currently active on a Dasan managed switch?
DASAN-SWITCH-MIB exposes port VLAN membership and trunk/link-aggregation group status objects, letting an operator confirm which ports belong to which VLAN and which trunk groups are currently up, useful when validating a switch's config matches what was intended after a change.

How would I check the forwarding table on a Dasan switch to troubleshoot a connectivity issue between two hosts?
The MIB provides forwarding table entries alongside per-port configuration state, so an administrator can poll which MAC addresses are learned on which ports and cross-reference that against port config to isolate where traffic is being dropped or misforwarded.
