Q. How do I interpret an unknown enterprise number?

A. If your error log file shows the following lines:

  • 14/02 15:13:07 TRAP CITRIX1:: coldStart14/02 15:13:07 TRAP CITRIX1:: linkUp, ifIndex = 114/02 15:13:07 TRAP CITRIX1:: linkUp, ifIndex = 1677721914/02 15:14:07 TRAP CITRIX1:: 1.3.6.1.4.1.3845.3.1.1 { }


The SNMP id is 1.3.6.1.4.1.3845.3.1.1

The "1.3.6.1.4.1..." prefix of the OID indicates that the trap is from a private enterprise MIB. You can find out what enterprise by downloading the Enterprise Numbers RFC from:

http://www.iana.org/assignments/enterprise-numbers

Reading through the file indicates this:

3845 Citrix Systems

You should contact the Citrix company (or read their MIB) to find out the exact interpretation of the trap's OID.
