Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Note Even though the shaped VP tunnel is defined as CBR, it can carry PVCs of another service category by
substituting the new service category after the tunnel interface has been initially configured. For
information about configuring VP tunnels with other (non-CBR) service categories, see theChapter 7,
“Configuring Virtual Connections.”.
Example
The following example shows how to configure a shaped VP tunnel.
CESwitch# configure terminal
CESwitch(config)# atm connection-traffic-table-row index 10 cbr pcr 4000
CESwitch(config)# interface atm 0/0/0
CESwitch(config-if)# shutdown
CESwitch(config-if)# atm pvp 1 shaped rx-cttr 10 tx-cttr 10
CESwitch(config-if)# no shutdown
CESwitch(config-if)# interface atm 0/0/0.1
CESwitch(config-subif)# exit
CESwitch(config)#
Note A shaped VP tunnel is defined as a CBR VP with a PCR. A maximum of 64 shaped VP tunnels can be
defined on each of the following interface groups: (0/0/x, 1/0/x), (0/1/x, 1/1/x), (2/0/x, 3/0/x), (2/1/x,
3/1/x), (9/0/x, 10/0/x), (9/1/x, 10/1/x), (11/0/x, 12/0/x) and (11/1/x, 12/1/x). For further limitations on
shaped VP tunnels, see the Chapter 7, “Configuring Virtual Connections.”.
Step 5
Switch(config-if)# atm pvp vpi [hierarchical |
shaped] [rx-cttr index] [tx-cttr index]
Configures a shaped VP tunnel, as follows:
• Specifies whether the tunnel is hierarchical
or shaped.
Note To configure a shaped VP tunnel to carry
PVCs of other (non-CBR) service
categories, the VP tunnel must be
configured as a hierarchical tunnel.
• Specifies the connection traffic table row in
the received direction. The default is 1.
• Specifies the connection traffic table row in
the transmitted direction. The default is 1.
Step 6
Switch(config-if)# no shutdown Reenables the interface.
Step 7
Switch(config-if)# interface atm
card/subcard/port.subinterface#
Switch(config-subif)#
Configures a subinterface.
Note You cannot create a subinterface on the
route processor interface ATM 0.
Step 8
Switch(config-subif)# exit
Switch(config)#
Exits subinterface mode.
