Module: AC-SYSTEM-MIB
OID (symbolic): AC-SYSTEM-MIB::acSysModuleFirstPortNum
OID (numeric): 1.3.6.1.4.1.5003.9.10.10.4.21.1.16
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The logical number as seen in the general trunk/analog-channel table of the first port in the module in question. Since analog and digital ports can be operational at once, analog and digital ports may have same logical number. AC INI-Param: N/A
What is acSysModuleFirstPortNum?
AC-SYSTEM-MIB::acSysModuleFirstPortNum tells you the logical port number (0-19) of the first physical port on a module, which is how the port appears in trunk or channel tables. You need this mapping when correlating physical hardware locations with logical port assignments, especially when analog and digital modules coexist and may use overlapping numbering. For instance, if the first port on a module has a logical number of 5, then that module's ports are numbered 5, 6, 7, etc. in the system tables.
