You cannot configure CAC on an ATM interface on which you have created a bulk-configured virtual circuit (VC) range for use by a dynamic ATM 1483 subinterface. Conversely, you cannot create a bulk-configured VC range on an ATM interface on which you have configured CAC. The router rejects these configurations, which causes them to fail.
If you are upgrading to the current JUNOSe software release from a lower-numbered release, configurations that use CAC and bulk configuration on the same ATM interface continue to work. However, we recommend that you disable CAC on these ATM interfaces to ensure continued compatibility with future JUNOSe releases.
For information about how to use the atm cac command to configure CAC, see Setting Optional Parameters. For information about how to use the atm bulk-config command to create a bulk-configured VC range, see Bulk Configuration of VC Ranges in Configuring Dynamic Interfaces Using Bulk Configuration.
