Chapter 7 Configuring Virtual Connections
Configuring VP Tunnels
Configuring a VP Tunnel for a Single Service Category
The type of VP tunnel described in this section is configured as a VP of a single service category.
Only virtual circuits (VCs) of that service category can transit the tunnel.
To configure a VP tunnel connection for a single service category, perform the following steps,
beginning in global configuration mode:
Note The row index for nondefault rx-cttr and tx-cttr must be configured before these optional parameters
are used.
Examples
The following example shows how to configure the ATM VP tunnel on the ATM switch router (HB-1)
at interface ATM 1/0/0, VPI 99:
Switch(HB-1)(config)# interface atm 1/0/0
Switch(HB-1)(config-if)# atm pvp 99
Switch(HB-1)(config-if)# exit
Switch(HB-1)(config)# interface atm 1/0/0.99
Switch(HB-1)(config-subif)# end
Switch(HB-1)#
Command Purpose
Step 1
Switch(config)# atm connection-traffic-table-row
[index row-index] [{vbr-rt | vbr-nrt} pcr pcr_value
{scr0 | scr10} scr_value [mbs mbs_value]
[cdvt cdvt_value] |
[cbr pcr pcr_value [cdvt cdvt_value] |
[abr pcr pcr_value [mcr mcr_value]
[cdvt cdvt_value] |
[ubr pcr pcr_value [mcr mcr_value]
[cdvt cdvt_value]]
Configures the connection-traffic-table-row
index for any nondefault traffic values
(optional).
Step 2
Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step 3
Switch(config-if)# atm pvp vpi [rx-cttr index]
[tx-cttr index]
Configures an interface permanent virtual path
(PVP) leg.
Step 4
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode.
Step 5
Switch(config)# interface atm
card/subcard/port.vpt#
Switch(config-subif)#
Creates a VP tunnel using a VP tunnel number
that matches the PVP leg virtual path identifier
(VPI).
