Description: Ubiquiti EdgeSwitch ISDP (Industry Standard Discovery Protocol) MIB for managing neighbor discovery and topology information.

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 EdgeSwitch-ISDP-MIB?

EdgeSwitch-ISDP-MIB is a Broadcom Inc (FastPath switch software, marketed under Ubiquiti EdgeSwitch) proprietary MIB implementing ISDP (Industry Standard Discovery Protocol, Cisco CDP-compatible neighbor discovery). Its interface table enables ISDP per port, a cache table, keyed by interface/index, records neighbor address, local interface, ISDP/protocol version, device ID/port, platform, capabilities, last-change time, and holdtime, and clear-statistics/clear-entries actions sit alongside PDU-sent/received counters (overall and per-ISDP-version). As a status/configuration MIB it lets an administrator discover directly connected neighbor devices and their capabilities on an EdgeSwitch. It is deployed on Broadcom FastPath-based switches (Ubiquiti EdgeSwitch). Engineers can download the EdgeSwitch-ISDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EdgeSwitch-ISDP-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

Broadcom FastPath-based switches (Ubiquiti EdgeSwitch and OEM variants)

Monitoring Examples

An administrator checks agentIsdpCacheDeviceId and agentIsdpCachePlatform to identify a directly connected neighbor device on an EdgeSwitch.

How to Use in IPNetwork Monitor

Example using agentIsdpStatisticsPduReceived OID:

Select an Ubiquiti EdgeSwitch (Broadcom FastPath-based) switch (Industry Standard Discovery Protocol) 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 agentIsdpStatisticsPduReceived into the Find box to locate it in the OID tree, then select it and click OK. It reports the display the number of all ISDP pdu received. 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 (in packets), 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.
