The main difference between a SNMP poll and a SNMP trap is which device initiates the communication. An SNMP poll is initiated by the SNMP server and the ICX-AlphaCom responds to the server. An SNMP trap is initiated by the ICX-AlphaCom when it has information to send (usually some event happened) and does not want to wait for the server to ask for information.

The ICX-AlphaCom and AlphaCom XE run a SNMP service, and supports SNMP polling and SNMP traps.

The main difference between a SNMP poll and a SNMP trap is which device initiates the communication. An SNMP poll is initiated by the SNMP server and the ICX-AlphaCom responds to the server. An SNMP trap is initiated by the ICX-AlphaCom when it has information to send (usually some event happened) and does not want to wait for the server to ask for information.


Stentofon MIB OID numbers

Zenitel Norway AS has assigned a Private Enterprise Number OID 26122.

The Zenitel Norway AS enterprise number is labeled enterprises.stentofon
Allocated Sub OIDs:

  • 1 - enterprises.stentofon.alphacom
  • 2 - enterprises.stentofon.ipstation


Note that the ICX-AlphaCom OID has of historical reasons not always followed the enterprise numbering defined above, see AlphaCom_MIB_revisions

SNMP poll

In addition to the AlphaCom MIB, the standard MIBs mibII, ucd-snmp and snmpv2 are implemented. These Mibs only implements polled information.

The ICX-AlphaCom MIB implements two main statuses:

Variable Object ID Comment
Nodestate 1.3.6.1.4.1.26122.1.1.1 AMC-IP status enabled/disabled. Shows if the AlphaCom is operational. Same info as in ICX-Web, Node State - Operational
RTP Statistics 1.3.6.1.4.1.26122.1.2.1 RTP audio statistics


All MIBs variables are accessed through SNMP v2 protocol with community = public. All variables are read only.

The default MIBs are always active, but in order to receive polling requests from an SNMP server you need to open the firewall (Filters) in ICX-Web (UDP port 161).

Define and enable UDP port 161 in Filters settings in ICX-Web


You also need to configure the System Information for the SNMP server from System Configuration / Logging / SNMP System Information

Configure the System Information for the SNMP Server.



SNMP Traps

The ICX-AlphaCom log events can be sent as SNMP traps.

The alert types that support SNMP traps have a number assigned to them, for example, 1001 is the number assigned to System Log events. The following table lists the number sent in the SNMP trap for each alert type.


Alert number Object ID Alert type Alert criteria
1001 1.3.6.1.4.1.26122.1.11.1001 Debug log events
  • Software debug information
1002 1.3.6.1.4.1.26122.1.11.1002 System log events
  • Station Line error
  • Board down
  • Device/MultiModule (card cage) error
  • AGA/AE1 audio line error
  • Software error
  • Remote Control Input on/off
  • Customized event logging (LOG command)
1003 1.3.6.1.4.1.26122.1.11.1003 Call Statistics log events
  • Point to point calls
  • Group Calls
  • Call Request
  • Ringing Group



SNMP trap is configured in ICX-Web, System Configuration > Logging. Select destination ‘SNMP Trap’ and configure which logs you want to send.

Configuration of SNMP Traps in ICX-Web



SNMP traps are using UDP port 162. As this is outbound data, there is no need to define this port in the Filters settings in ICX-Web.

ICX-AlphaCom MIB file

Revision 3:

  • OID enterprises.26122
  • Added missing imports giving MIB validation errors.
  • Removed some unused import definitions

Revision 2:

  • OID enterprises.26122
  • Updated with Zenitel enterprise OID and snmptrap definition for AlphaCom syslog to snmptraps log facilities

Revision 1:

  • OID: enterprises.9362
