How to Access MIBs

MIBS can be accessed through any MIB Browser (i.e. iReasoning). The MIB Browser enables you to view the MIBS from any device (such as the SBC 1000/2000).

The following example displays the MIB tree for the SBC 1000/2000 Global Call Counters (uxGlobalCallCounters).

Standard MIB Support

Sonus SBC 1000/2000 also extends the standard interface table MIB to include partial support for the following:


The SBC Edge supports the IF MIB as described here:

  • The ifStack and ifRcvAddress tables list only the physical interfaces.

The ifIndex attribute inthe ifTable is interpreted as follows:

0-9Channel number
10-15Port number
18-21Card number
22-25Shelf number
300 = Kernel, 1 = User. All Ethernet interfaces are 0 and DS1 are 1.
31No Used, always 0.

The kernel assigns ifIndex sequentially based on the order the interfaces are brought up.


The SBC Edge supports partial DS0 MIB support through the dsx0Configtable table. The DS0 MIB is based on RFC 2494.


The SBC Edge provides partial support for the DS1 MIB. The DS1 MIB is based on RFC 4805.

Host Resources MIB

The SBC Edge provides partial support for the Host Resources MIB. The Host Resources MIB is based on RFC 2790.
