Planning the System
The bandwidth usage numbers shown above assume 6 bytes for Multilink Point-to-Point
Protocol (MP) or Frame Relay Forum (FRF), 12 Layer 2 (L2) header, and 1 byte for the
end-of-frame flag on MP and Frame Relay frames for a total of 7 byte headers only. They do not
account for silence suppression or header compression techniques, which might reduce the
actual bandwidth. For other types of networks (such as Ethernet or ATM) or for cases where
there is a lot of silence suppression or header compression being used, the network might be
better modeled by administering the CAC-BL limits in terms of number of connections rather
than bandwidth used.
Instructions
Note:
All DIRECT links must be administered first, and INDIRECT links administered
Note:
last.
To set bandwidth limitations between directly-connected network regions:
1. Type change ip-network region <n>, where n is the region number you want to
administer. Press Enter.
2. The IP Network Region
3. Scroll to page 3 of the form, Inter Network Region Connection Management.
4. In the codec-set field, enter the number (1-7) of the codec set to be used between the two
regions.
5. In the Direct WAN field, enter y.
6. In the WAN-BW-limits field, enter the number and unit of measure (Calls, Kbits, Mbits, No
Limit) that you want to use for bandwidth limitation.
7. Press Enter to save your changes.
To set bandwidth limitations between indirectly-connected network regions:
1. Type change ip-network region <n>, where n is the region number you want to
administer. Press Enter.
The IP Network Region
2. Scroll to page 3 of the screen, Inter Network Region Connection Management.
3. In the codec-set field, enter the number (1-7) of the codec set to be used between the two
regions.
4. In the Direct WAN field, enter n.
5. In the Intervening-regions fields, enter up to four intervening region numbers between the
two indirectly connected regions.
