SNMP support for SS7
The SS7 MIB (mgstat.mib) is implemented as a branch object with the main object, mgGroup, linked into the Ascend enterprise MIB. For definitions and descriptions of objects, see the mgstat.mib file distributed with TAOS 8.0.2 software.
An SNMP trap is supported for reporting the status of the link between SS7 media gateways and the TAOS unit. The trap can be configured when an SS7 license is enabled. For a trap to be generated when the trap condition occurs, SNMP traps must be enabled and the setting for the trap condition must be enabled. For details about enabling traps, see the APX 8000/MAX TNT/DSLTNT Administration Guide.
The following trap has been added to the Ascend enterprise traps:
megacoLinkStatusTrap | |
ENTERPRISE | ascend |
VARIABLES | { mgLinkName, mgOperStatus } |
DESCRIPTION | "This trap indicates that operational status |
| of a media gateway control link has changed." |
::= 42 |
|
Following is the relevant parameter in the Trap profile, shown with its default value, for enabling the trap:
[in TRAP/""]
Parameter
Specifies
Enable/disable trap generation of communication link status between the SS7 media gateway and the TAOS unit. This trap indicates that operational status of a media gateway control link has changed from any state to the Up state or from Up state to any other state. Changes to this parameter become effective when you write the Trap profile.
The trap contains the name of the link, which is currently always reported as default, and the new operational status.
For example, the following commands enable the SS7
admin> read trap example TRAP/example read
admin> set
admin> write TRAP/example written
