System Management MIB (ap-smgmt.mib)

The following table describes the SNMP GET query names for the System Management MIB (ap-smgmt.mib).

Notes on ENUM Server Names

Note that the characters of the name are given in the ASCII values because of SNMP’s restrictions. This representation affects the order in which entries in the table appear. Entries are listed:

  • By the length of their names
  • Then by a comparison of the characters they contain; this comparison is not limited to alphabetical order in that uppercase letter precede lowercase characters
  • Last, by the IP address of the server for that entry

Take, for example, the case where there are three ENUM configurations:

  • aaa, with servers 1.1.1.1 and 1.1.1.2
  • BBB, with servers 3.3.3.3 and 3.3.3.2
  • cc, with server 2.2.2.2

The entries would appear in the following order, with the following instance IDs:

  1. cc 2.2.2.2 would appear first because cc is the shortest name), and would be represented by the instance ID: … .2.99.99.2.2.2.2
  2. BBB entries would be next, sorted by IP address, because “BBB” is considered less than aaa, and would be represented by the instance IDs: … .3.66.66.66.3.3.3.2 and … .3.66.66.66.3.3.3.3
  3. aaa entries would appear last, represented by the instance IDs: ... .3.97.97.97.1.1.1.1 and ... .3.97.97.97.1.1.1.2
