Chapter 21 Configuring ATM Connections
rt-VBR and nrt-VBR Connections
• CDVT
• FBTC flag
• SCR
• MBS
• Policing Type
There is no change in CDVT usage and the previous policing system.
When using the addcon command without the extended parameters, rt-VBR connections automatically
use the parameters provided by connection class 3 which contains pre-determined values. Similarly,
nrt-VBR connections use connection class 2.
To modify the values of a connection class, use the commands cnfcls and cnfatmcl.
To display these values, use the commands dspcls and dspatmcls.
