Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is S5-ETHERNET-COMMON-MIB?

S5-ETHERNET-COMMON-MIB is a Nortel/Avaya BayStack MIB defining Ethernet port objects shared across multiple BayStack device families, serving as a base port model for other S5-family MIBs. It exposes per-port link, partition, and jabber status alongside board/port index information. Its monitoring value is hardware interface health: link status shows up/down state, jabber status flags a malfunctioning NIC flooding the segment, and partition status/time shows when a port was auto-disabled due to excessive collisions. As a common/base MIB it is directly depended upon by other S5-family MIBs such as S5-ETH-REDUNDANT-LINKS-MIB. It is typically deployed across the full range of Nortel/Avaya BayStack Ethernet switches wherever basic port-level fault status is needed. Engineers can download the S5-ETHERNET-COMMON-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in S5-ETHERNET-COMMON-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

Avaya/Nortel BayStack Ethernet switches

Monitoring Examples

An admin polls s5EnPortTable/s5EnPortEntry, keyed by s5EnPortBrdIndx and s5EnPortIndx, to check s5EnPortLinkStatus for link up/down state and s5EnPortJabberStatus to detect a malfunctioning NIC flooding the segment; s5EnPortPartStatus and s5EnPortPartTime reveal whether a port was auto-partitioned (disabled) due to excessive collisions, with the extension table s5EnPortExtTable/s5EnPortExtEntry providing additional per-port detail.

What Can Be Monitored

port link status
port partition (auto-disable) status
port jabber status
partition time
extended port status detail

How to Use in IPNetwork Monitor

Example using s5EnBStatGoodOctets OID:

Select an Avaya/Nortel BayStack Ethernet switch (shared per-port link/jabber/partition 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 s5EnBStatGoodOctets 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. It reports a count of octets contained in frames received which had no errors. 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.

s5EnPortTable	1.3.6.1.4.1.45.1.6.6.1.1		not-accessible	A table containing information about each managed ethernet connectivity port on a board. The number of entries is determined by the number of managed ports. Those boards that do not have any ports do not have any entries in this table.
s5EnPortEntry	1.3.6.1.4.1.45.1.6.6.1.1.1		not-accessible	A row in Ethernet port table. Entries can not be created or deleted via SNMP.
INT s5EnPortBrdIndx	1.3.6.1.4.1.45.1.6.6.1.1.1.1	INTEGER	read-only	The index of the board. This corresponds to the index of the slot containing the board.
INT s5EnPortIndx	1.3.6.1.4.1.45.1.6.6.1.1.1.2	INTEGER	read-only	The index of the port on the board. Its value ranges between 1 and index of the last manageable port on the board.
INT s5EnPortPartStatus	1.3.6.1.4.1.45.1.6.6.1.1.1.3	INTEGER	read-write	The partition status of the port. The following values can be written: enabled(2)..........enabled port partition(3)........partition port timedPartition(5)...time partition port (uses value from s5EnPortPartTime) The following values reflect the partition status of the port: other(1).............partition status unknown enabled(2)...........port enabled partition(3).........port partitioned autoPartition(4).....port auto-partitioned by hardware timedPartition(5)....port is timed partitioned (see value of s5EnPortPartTime). On GETs with port status of timedPartition(5), if the time remaining before the partition is undone is available, it will be reported in object s5EnPortPartTime as a positive value. If not available, the value of s5EnPortPartTime will be zero. When changing a port to timedPartition(5), the SET request must also contain the value for object s5EnPortPartTime. Only value partition(3) will survive resets of the host card.

This object can only be written in the same request that sets s5EnPortPartStatus to timedPartition(5). Afterwards, it indicates the amount of time left before the timed partition is completed, at which time s5EnPortPartStatus is changed to enabled(2). This object has the value of zero if the port is not time partitioned, or if the amount of time is not available.
INT s5EnPortLinkStatus	1.3.6.1.4.1.45.1.6.6.1.1.1.5	INTEGER	read-only	Tells whether the port is receiving link status. The values are: other(1)...returned for AUI off(2).....link is not connected on(3)......link is connected on/off applies to 10BASE-T and Fiber ports only.
