Frequently asked questions on the ACE SNMP implementation

Witch functions of SNMP are implemented?

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

The AlphaCom MIB implements two main statuses:

• amc status (Enabled/Disabled) (Same as AlphaWeb Node State/Operational)
• rtp statistics (Audio Statistics)

All MIBS variables are accessed through SNMP v2 protocol with community public. All variables are read only. Example of reading the AlphaCom MIB with NET-SNMP:

> snmpwalk –v 2c –c public localhost enterprises.9362

Where to get the MIB configuration file?

The active MIB file for a ACE board can be found in the folder :

/usr/local/share/snmp/mibs/ALPHACOM-MIB.txt

It can also be read here: AlphaCom MIB

How to activate SNMP in AC?

The default MIBS are always active, but you need to open the firewall in AlphaWeb (UDP port 161) If you need to log to snmp (snmp traps) it is possible to configure this in AlphaWeb ‘System Configuration’ / ‘Logging’ Select destination ‘SNMP Trap’ and configure which logs you want to send. The SNMP traps will be sent with the OID: enterprises.1000.1 (This may be subject to change since it is not using our own Zenitel SNMP OID) As a general rule it is better to use syslog directly for these kinds of log events and not SNMP. Most Building Management Systems handles both syslog and SNMP. The SNMP log options is implemented to serve systems that do not handle syslog..

Witch function of SNMP in AC will be implemented in near future?

There is at this moment not any plans for more snmp implementation.
