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 soft PVP connections used in the examples in this section.
