Description: Manages physical port configuration, status, and statistics on Accedian MetroNID Ethernet performance monitoring devices.

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 ACD-PORT-MIB?

ACD-PORT-MIB is an Accedian Networks proprietary MIB exposing per-port configuration and identity on Accedian network demarcation devices. Its data covers port name/alias, MAC address, connector type, administrative state, MTU, and auto-negotiation configuration. As a configuration-status MIB it lets an administrator confirm a port's operational parameters (MTU, auto-negotiation, state) match the intended service configuration before diagnosing a connectivity or performance issue further upstream. It is deployed on Accedian MetroNID and similar carrier Ethernet demarcation devices. Engineers can download the ACD-PORT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACD-PORT-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.

Monitoring Examples

An administrator checks acdPortConfigMtu and acdPortConfigAutoNegoState for a port reporting unexpectedly low throughput, ruling out an MTU mismatch or a failed auto-negotiation before escalating further.

How to Use in IPNetwork Monitor

Example using acdPortTxStatsBytesGood OID:

Select an Accedian MetroNID device 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 acdPortTxStatsBytesGood 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. This is a count of the total number of bytes transmitted by the port in good packets. 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 Counter64-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 Octets), 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.

A packet is ignored if it violates the programmed preamble rules or it violates the minimum data gap. The preamble rules include long preamble enforcement (greater than 23 nibbles) and pure preamble enforcement (only 55h bytes). The minimum data gap is the time between packet data transfers and is measured from immediately after the last CRC byte of the previous packet through the SFD field of the current packet. The normal data gap is 20 bytes long (12 bytes of IPG and 8 bytes of preamble/SFD). The enforcement limit is set to 10 bytes (half the normal gap length).

C64 acdPortTxStatsBroadcastPkts	1.3.6.1.4.1.22420.2.9.1.3.1.1.7	Counter64	read-only	This is a count of the good broadcast packets transmitted by this port (good means not dropped and valid CRC). Broadcast packets are identified by a destination address of all 1.
C64 acdPortTxStatsBytesGoodEx	1.3.6.1.4.1.22420.2.9.1.3.1.1.3	Counter64	read-only	This is a count of the total number of bytes transmitted by the port in good packets. The count includes the 4 CRC bytes but does not include the preamble or SFD bytes. A good packet is one that has been transmitted successfully (not aborted) with a good CRC. It is assumed that all transmit packets are properly sized, 64 bytes (after any padding) to maxsize bytes long.
C64 acdPortTxStatsBytesTotal	1.3.6.1.4.1.22420.2.9.1.3.1.1.4	Counter64	read-only	This is a count of the total number of bytes transmitted by the port in good and bad packets. The count includes the 4 CRC bytes but does not include the preamble or SFD bytes. Bad packets include normal collisions, late collisions, and FIFO underflows. For collisions, all bytes transmitted before the start of the collision as well as the colliding and jam bytes are counted. For FIFO underflows, all bytes actually transmitted are counted.
C64 acdPortTxStatsCRCErrors	1.3.6.1.4.1.22420.2.9.1.3.1.1.10	Counter64	read-only	This is a count of the transmitted packets with a bad non-appended CRC field. This count doesn't include any packets with a bad CRC due to a FIFO underflow.
C64 acdPortTxStatsDeferred	1.3.6.1.4.1.22420.2.9.1.3.1.1.11	Counter64	read-only	This is a count of the number of packets that were deferred on the first transmit attempt due to the medium being busy. Packets with subsequent deferrals (for instance, after a collision back off) are not counted. Whether the packet is eventually transmitted successfully or not is irrelevant to this counter. Packets dropped due to excess deferral that occur during the initial transmit attempt are not counted.
acdPortTxStatsEntry	1.3.6.1.4.1.22420.2.9.1.3.1.1		not-accessible	port transmit statistics.
C64 acdPortTxStatsExcessiveCollisions	1.3.6.1.4.1.22420.2.9.1.3.1.1.15	Counter64	read-only	This is a count of the number of packets dropped by this port due to excess collisions (number of collisions equals MaxRetry+1). This count does not include packets dropped due to FIFO underflow or late collisions (even if the late collision is also an excessive collision).
C64 acdPortTxStatsExcessiveDeferrals	1.3.6.1.4.1.22420.2.9.1.3.1.1.12	Counter64	read-only	This is a count of the number of packets dropped by this port due to excessive deferral. The deferral time starts at the beginning of each transmission attempt and ends when the transmission starts (regardless of collisions). The deferral is excessive if more than 3036 byte times have passed without the transmission starting.
C64 acdPortTxStatsFifoErrors	1.3.6.1.4.1.22420.2.9.1.3.1.1.18	Counter64	read-only	This is a count of the number of packets dropped by this port due to an underflow in the transmit FIFO. When an underflow is detected, transmission is immediately aborted after sending a known bad (inverted) CRC sequence. The FIFO underflow error takes precedence over all other errors if this counter is incremented, then none of the other packet type counters are incremented.
