Configuring ATM VC Classes
of configuration information for ATM PVCs created with the atm pvc command
depends on the JUNOSe software release from which you are upgrading, as
follows:
When you upgrade to the current JUNOSe software release from a JUNOSe
release numbered lower than Release 7.3.x, the output of the show
configuration command uses the pvc command format (pvc vcd vpi/vci) to
display configuration information for all ATM PVCs. This occurs even if those
PVCs were created in a JUNOSe release numbered lower than Release 7.3.x
with the atm pvc command. For example, assume that you created a PVC
in JUNOSe Release 7.2.x by issuing the command atm pvc 2 0 33 aal5snap
0 0 0. The show configuration command in the current JUNOSe software
release displays the identifier for this PVC as follows:
pvc 2 0/33
When you upgrade to the current JUNOSe software release from JUNOSe
Release 7.3.x or a higher-numbered release, the output of the show
configuration command uses the atm pvc command format to display
configuration information for ATM PVCs created with the atm pvc command.
For example, assume that you created a PVC in JUNOSe Release 7.3.x or
Release 8.0.x by issuing the command atm pvc 2 0 33 aal5snap 0 0 0. The
show configuration command in the current JUNOSe software release
displays the identifier for this PVC as follows:
atm pvc 2 0 33 aal5snap 0 0 0
For PVCs previously created in the lower-numbered release by using the pvc
command, the show configuration command displays configuration
information using the pvc command format, as described previously.
Delete any PVCs created with the atm pvc command and recreate them by using
the pvc command. For information about creating a data PVC by using the pvc
command, see "Creating Data PVCs" on page 47.
Configure the VC class as described in "Configuring VC Classes" on page 59.
Assign the VC class in one of the following ways:
