Configuring Soft PVP Connections
The following example modifies the packet discard option to Off for an existing soft PVC.
Switch(config)# interface atm 0/0/3
Switch(config-if)# atm soft-vc 8 990 pd off
The following example specifies different receive and transmit CTTR indexes and PD option for an
existing soft PVC.
Switch(config)# interface atm 0/0/3
Switch(config-if)# atm soft-vc 8 990 rx-cttr 444 tx-cttr 444 pd off
The following example displays the receive and transmit CTTR indexes and packet-discard-option for
the soft PVC configured on ATM interface 0/0/3.
Switch# show atm connection-traffic-table 444
Row Service-category pcr scr/mcr mbs cdvt pd
444 cbr 256 none off
The following example specifies the CTTR index and specifies the PD use the PD option specified in the
CTTR index.
Switch(config)# interface atm 0/0/3
Switch(config-if)# atm soft-vc 8 990 rx-cttr 444 tx-cttr 444 pd use-cttr
Configuring Soft PVP Connections
This section describes configuring soft permanent virtual path (PVP) connections, which provide the
following features:
Connection to another host or ATM switch router that does supports signalling
Configuration of PVPs without the manual configuration steps described in the “Configuring Virtual
Channel Connections” section on page 2.
Configuration of PVPs with the reroute or retry capabilities when a failure occurs within the network
Figure 7-7 is an illustration of the softPVP connections used in the examples in this section.
