Configuring Virtual Connections
Configuring Terminating PVC Connections
To configure both point-to-point and point-to-multipoint terminating PVC connections, perform the
following steps, beginning in global configuration mode:
When configuring point-to-multipoint PVC connections using the
atm pvc
command, the root point is
port A and the leaf points are port B.
Note
The row index for
rx-cttr
and
tx-cttr
must be configured before using this optional parameter. See
Chapter 9, “Configuring Resource Management.”
Note
This parameter specifies the weight assigned to the output VC for weighted round robin scheduling and
is an integer in the range of 1 to 15.This parameter is valid only on systems equipped with the switch
processor feature card. (Catalyst 8540 MSR and Catalyst 8510 MSR and LightStream 1010 with
FC-PFQ). For more information on scheduling, see “Scheduling Output” in the
Guide to ATM
Technology.
Note
The
sched
option is only available on OC-48c interfaces. Each OC-48c interface has four OC-12
schedulers. The
sched
variable is used to select the specific OC-12 scheduler for which the virtual circuit
is assigned for output on an interface and is therefore a number between 1 and 4.
Examples
The following example shows how to configure the internal cross-connect PVC between interface
ATM 3/0/1, VPI = 1, VCI = 50, and the terminating connection at the route processor interface ATM 0,
VPI = 0, and VCI unspecified:
Switch-B(config)#
interface atm 3/0/1
Switch-B(config-if)#
atm pvc 1 50 interface atm0 0 any-vci encap aal5snap
The following example shows how to configure the route processor leg of any terminating PVC:
Switch(config)#
interface atm0
Switch(config-if)#
atm pvc 0 any-vci
