# Configuring Bandwidth Management to ICPs with 3300 ICP Rel 7.1 UR2 or Lower

If you have ICPs in your network that are running 3300 ICP Release 7.1 UR2 software or lower, you can apply bandwidth management to them, providing the managing system is of a software release version of 8.0 or higher. This condition could occur when a network is being converted to a newer software release in a staged approach.

The following diagram illustrates such a configuration, where the Headquarters Office has been upgraded to release 8.0, while the Regional Office has not yet been upgraded to the current release.

3300 ICP Release 8.0 or Higher System to Release 7.1 UR2 or Lower System

In order to measure the bandwidth utilized between the two regions, you must configure a "Perimeter" zone to separate any pre-8.0 system from the 8.0 system, and measure the bandwidth going to/from the bottleneck.

The IT Administrator has assigned the following bandwidth limits for the voice media streams through the ZAP as follows:

ZAP Label | Bandwidth Limit
Toronto-Ottawa | 500 kbit/s

The following Zone Diagram illustrates how the network would appear:

Zone Configuration Between 3300 ICP Release 8.0 and Pre-Release 8.0 System

You would complete the following programming to support this configuration:

Network Elements |  | Zone Tree Assignment
Name | Zone |  | Zone | Parent Zone | Perimeter
Ottawa (Local) | 2 |  | 2 | -- | No
Toronto | 4 |  | 4 | 2 | Yes

Zone Access Point Assignment (Summary)
Zone | Zone Access Point ID | ZAP Label | Bandwidth Limit | Network Element
4 | 1 | Toronto-Ottawa | 500 | Ottawa
