Description: Manages Tiara Networks WAN router system identity, software version, and configuration.

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 TIARA-NETWORKS-SYSTEM-MIB?

TIARA-NETWORKS-SYSTEM-MIB is a Tiara Networks proprietary MIB covering the system-level configuration, VLAN statistics, and Ethernet failover management for Tiara's WAN router products. Its systemObjects group exposes host identity and network configuration (sysIpAddr, sysNetMask, sysHostName, sysDomainName, sysVersion) plus overall alarm status (sysAlarmStatus) and administrative reset/clear controls (sysReset, arpClearAtTable, ipClearRouteTable); dnsGroup manages up to three configured DNS servers via dnsServerTable; ethernetFailOverGroup's tiaraEthernetFailOverTable configures per-interface failover enable and hold-down timing for source-forwarded traffic switching between redundant Ethernet interfaces; and vlanGroup's vlanStatsTable reports per-VLAN transmitted, received, and dropped packet counters. A set of TRAP-TYPE notifications (failOverNotification/failOverFailNotification, shutDownNotification, userLoginNotification/userLogOffNotification/userLoginFailNotification) alert on failover events, system shutdowns, and user access activity. Monitoring this MIB together lets an operator confirm system health (alarm status), track Ethernet redundancy behavior, and watch VLAN traffic and drop rates on a Tiara WAN router. It depends on the TIARA-NETWORKS-SMI enterprise registration tree for its OID root and is deployed on Tiara Networks WAN routers/access devices, and network teams supporting this legacy hardware searching for the TIARA-NETWORKS-SYSTEM-MIB download will use it to poll system, failover, and VLAN health via SNMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIARA-NETWORKS-SYSTEM-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

Tiara Networks WAN router / access equipment

Monitoring Examples

An operator polls sysAlarmStatus to confirm no WAN interface alarms are active and watches vlanDroppedPkts in vlanStatsTable for a given vlanTag; a sysAlarmStatus of major combined with a spike in vlanDroppedPkts for the VLAN carrying that WAN link would indicate a physical-layer problem is causing traffic loss.

What Can Be Monitored

system IP configuration, hostname, and software version
overall alarm status
DNS server table configuration
per-interface Ethernet failover enable and hold-down timer state
per-VLAN transmitted/received/dropped packet counters
failover and user-access trap notifications

How to Use in IPNetwork Monitor

Example using vlanTxPkts OID:

Select a Tiara Networks WAN router/access equipment (system alarm/Ethernet-failover/VLAN traffic status) 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 vlanTxPkts 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. Packets transmitted on this VLAN. 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.
