Description: Brocade Foundry POS (Packet over SONET) group MIB providing configuration and performance objects for SONET WAN interface modules on FastIron.

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 FOUNDRY-SN-POS-GROUP-MIB?

FOUNDRY-SN-POS-GROUP-MIB is a Brocade (formerly Foundry Networks) enterprise MIB for Packet-over-SONET (POS) interface modules used in FastIron switches/routers, providing configuration and performance data for SONET/SDH WAN interfaces. It exposes a POS information table covering port number, associated ifIndex, descriptive name, line speed, administrative status, link status, clocking source, loopback mode, and ATM scrambling setting. As a monitoring tool it is used to track hardware/interface status -- particularly whether a POS/SONET WAN port's link is up or down, its configured clock source, and whether it has been placed into a diagnostic loopback mode -- which are key indicators of physical-layer WAN health. It depends on the standard Interfaces MIB (ifIndex/ifTable) to correlate each POS port entry with the generic interface layer. It is typically deployed on Brocade/Foundry FastIron routers and switches carrying SONET/SDH WAN circuits in carrier or enterprise WAN-edge environments, typically beginning with a FOUNDRY-SN-POS-GROUP-MIB download to load its object definitions into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FOUNDRY-SN-POS-GROUP-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

Brocade/Foundry FastIron router or switch with SONET/POS WAN module

Monitoring Examples

An administrator polls snPOSInfoTable (snPOSInfoEntry fields snPOSInfoPortNum, snPOSIfIndex, snPOSInfoSpeed, snPOSInfoAdminStatus, snPOSInfoLinkStatus) to verify that a SONET POS circuit is administratively up and the link is actually synchronized. If snPOSInfoLinkStatus shows down while snPOSInfoAdminStatus is up, this reveals a physical SONET link failure (e.g., loss of signal) needing investigation. Checking snPOSInfoLoopBack confirms whether the port has been intentionally placed into a test loopback mode, and snPOSInfoClock verifies the interface is using the correct timing source to avoid clock slips.

What Can Be Monitored

POS/SONET port admin and link status
interface line speed
clock source configuration
loopback mode status
ATM cell scrambling setting

How to Use in IPNetwork Monitor

Example using snPOSStatsInFrames OID:

Select a Brocade/Foundry FastIron switch/router with SONET/POS WAN module 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 snPOSStatsInFrames 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 total number of packets received on the interface. 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.
