Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

This section describes how to check the number of BFS sessions on your system to determine whether any
unused VCIs are present for the inband BFS carousel.



Your network was initially installed and reserved with 20 Virtual Channel Indicator (VCI) connections

(values 256-275) on the ATM switch. The VCIs carry inband BFS information from the DNCS to the BIG.
Because you will create a new inband source, you must make sure that one VCI is available for each
additional bootloader carousel that you add to the DNCS.



If you need detailed instructions for this procedure, refer to the manual that came with your ATM

switch.

Complete the following steps to determine whether there are enough unused VCIs available for the additional
inband BFS carousels.

1.

Using the manual that came with your ATM switch, check the ATM switch to determine the number of

unused VCIs.

2.

Are there enough VCIs for the new bootloader carousels?



If yes, go to 



If no, add more VCIs to the switch. Then, go to 

Note: Having unused VCIs does not present any issues to your system; therefore, we
recommend that you create 5 to 10 extra VCIs.
