3Com VCX V7122/SIP VoIP Gateway User Manual

The Trunk MIB contains objects relevant to E1/T1 Trunk interfaces. In this version, only the
dsx1ConfigTable fields and dsx1LineStatusChange NOTIFICATION (Trap) are supported.
Traps are received by an SNMP manager using a Network Interface.
VCX V7122/SIP Self-Testing
The VCX V7122/SIP features two self-testing modes: rapid and detailed.
Rapid self-test mode is invoked each time the Gateway completes the initialization process.
This is a short test phase in which the only error detected and reported is failure in initializing
hardware components. All Status and Error reports in this self-test phase are reported
through Network Interface ports, as well as indicated by the LED Status Indicators.
Detailed self-test mode is invoked when initialization of the Gateway is completed and if the
configuration parameter EnableDiagnostics is set to 1 (this parameter can be configured
through the INI
file mechanism). In this mode, the Gateway tests all the hardware
components (such as memory or DSP), outputs the status of the test results, and ends the
test. To continue operational running, reset the Gateway again but this time configure the
EnableDiagnostics parameter to 0.
SysLog Support
Overview
SysLog protocol is an event
notification protocol that allows a machine to send event
notification messages across IP networks to event message collectors, also known as
SysLog Servers. The Syslog protocol is defined in RFC 3164 IETF standard.
Since each process, application, and operating system was written somewhat independently,
there is little uniformity to SysLog messages. For this reason, no assumption is made on the
contents of the messages other than the minimum requirements of its priority.
SysLog uses UDP as its underlying transport layer mechanism. The UDP port that has been
assigned to SysLog is 514.
The SysLog message is transmitted as an ASCII message. The message starts with a
leading < (less-than character), followed by a number, which is followed by a > (greater-than
character). This is optionally followed by a single ASCII space.
This number is known as the Priority and represents both the Facility and Severity. The
Priority number consists of one, two, or three decimal integers.
