CISCO_SESS_BORDER_CTRLR_STATS_MIB

Revision: 2010-09-15

The main purpose of this MIB is to define the statistics information for Session Border Controller application. This MIB categorizes the statistics information into following types: 1. RADIUS Messages Statistics - Represents statistics of

various RADIUS messages for RADIUS servers with which the client (SBC) shares a secret.
  1. Rf Billing Statistics- Represents Rf billing statistics information which monitors the messages sent per-realm over IMS Rx interface by Rf billing manager(SBC).
  2. SIP Statistics - Represents SIP requests and various SIP responses on a SIP adjacency in a given interval.

The Session Border Controller (SBC) enables direct IP-to-IP interconnect between multiple administrative domains for session-based services providing protocol inter-working, security, and admission control and management. The SBC is a voice over IP (VoIP) device that sits on the border of a network and controls call admission to that network.

The primary purpose of an SBC is to protect the interior of the network from excessive call load and malicious traffic. Additional functions provided by the SBC include media bridging and billing services.

Periodic Statistics - Represents the SBC call statistics information for a particular time interval. E.g. you can specify that you want to retrieve statistics for a summary period of the current or previous 5 minutes, 15 minutes, hour, or day. The statistics for 5 minutes are divided into five minute intervals past the hour - that is, at 0 minutes, 5 minutes, 10 minutes... past the hour. When you retrieve statistics for the current five minute period, you will be given statistics from the start of the interval to the current time. When you retrieve statistics for the previous five minutes, you will be given the statistics for the entirety of the previous interval. For example, if it is currently 12:43 - the current 5 minute statistics cover 12:40 - 12:43

  • the previous 5 minute statistics cover 12:35 - 12:40

The other intervals work similarly. 15 minute statistics are divided into 15 minute intervals past the hour (0 minutes, 15 minutes, 30 minutes, 45 minutes). Hourly statistics are divided into intervals on the hour. Daily statistics are divided into intervals at 0:00 each day. Therefore, if you retrieve the statistics at 12:43 for each of these intervals, the periods covered are as follows. - current 15 minutes: 12:30 - 12:43

  • previous 15 minutes: 12:15 - 12:30
  • current hour: 12:00 - 12:43
  • last hour: 11:00 - 12:00
  • current day: 00:00 - 12:43
  • last day: 00:00 (the day before) - 00:00.
