Description: Offers system-level management data for Avici backbone routers, covering uptime, software version, and overall health status.

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 AVICI-SYSTEM-MIB?

AVICI-SYSTEM-MIB is a proprietary MIB from Avici Systems covering system-level management of its large-capacity backbone routers. It exposes system identification objects (router ID, system type) along with a hardware inventory table enumerating chassis components such as bays, slots, and modules along with their operational status. It is explicitly geared toward monitoring hardware status: aviciSysInventoryOperStatus reports whether each inventoried FRU is up, down, or degraded, and the module also carries change-notification traps (aviciSysInventoryTableChange, aviciSysTrapDescr) so that hardware insertions, removals, or failures are surfaced in real time alongside general system uptime and software version data typically found alongside a SYSTEM group. Within the AVICI-SYSTEM-MIB MIB, the inventory table and its associated traps form the primary interface network operations teams use to track chassis-level hardware events. It builds on the standard SNMPv2-SMI/SNMPv2-CONF conventions and is meant to be used together with Avici's other product-specific MIBs for interfaces and routing. It is deployed on carrier and ISP backbone routers where continuous visibility into chassis health is essential for high-availability operation.

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

Avici backbone/core router

Monitoring Examples

An administrator would walk aviciSysInventoryTable to enumerate every aviciSysInventoryEntry by aviciSysInventoryBay and aviciSysInventorySlot, checking aviciSysInventoryOperStatus for each aviciSysInventoryId to spot a failed or missing line card. A sudden aviciSysInventoryTableChange trap combined with an operStatus transition to 'down' on a given slot would indicate a hardware fault or hot-swap event needing investigation. Polling aviciSysRouterId and aviciSysType alongside the inventory table gives a quick health snapshot of the whole chassis.

What Can Be Monitored

router identifier and type
chassis inventory by bay/slot
module operational status
hardware inventory change events

How to Use in IPNetwork Monitor

Example using aviciSysInventoryTableChange OID:

Select an Avici backbone/core router 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 aviciSysInventoryTableChange into the Find box to locate it in the OID tree, then select it and click OK. It reports, in TimeTicks (hundredths of a second since the system last rebooted), when the hardware inventory table was last changed — for example, when a module was added or removed. 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 TimeTicks-type OID, Value bounds is the most useful condition here — trigger an alert if this value changes unexpectedly (e.g. outside a planned maintenance window), since that flags an unplanned hardware inventory change. Click Finish to create the monitor; you can adjust any parameter later.
