Configuring Virtual Private Tunnels; Verifying An Atm Interface Connection Status - Cisco RJ-45-to-AUX Brochure

CoriolisLS1010> enable
2. Use the config terminal command to enter Global Configuration mode:
CoriolisLS1010# config terminal
3. You must identify the route for traffic to take to the internal network (referred to as a static route)
using the ip route command, as shown here:
CoriolisLS1010(config)# ip route 63.78.127.0 255.255.255.0 ethernet 0
4. Enter Interface Configuration mode for the Ethernet interface:
CoriolisLS1010(config)# interface ethernet 0
5. Assign the IP address and subnet mask to the interface just as you would a switch or router Ethernet
interface, and then exit:
CoriolisLS1010(config−if)# ip address 63.78.127.2 255.255.255.0
CoriolisLS1010(config−if)# ^C
CoriolisLS1010#

Configuring Virtual Private Tunnels

A virtual private tunnel provides a way to link two private ATM networks across a public network. This type
of network only supports PVCs. Connecting this way provides a permanent path through the public network.
The public network trunks all the virtual channels in the VP between the two networks. The following
example shows how to configure the VP tunnel when the VPI equals 2:
1. Use the enable command to enter Privileged EXEC mode:
CoriolisLS1010> enable
2. Use the config terminal command to enter Global Configuration mode:
CoriolisLS1010# config terminal
3. Enter the interface on the module:
CoriolisLS1010(config)# interface atm 3/0/2
4. Identify the private virtual path (PVP) number:
CoriolisLS1010(config−if)# atm pvp 2
5. Create an ATM subinterface. This example uses the PVP number as the sub−interface number:
CoriolisLS1010(config−if)# interface atm 3/0/2.2
CoriolisLS1010(config−subif)# end
CoriolisLS1010#

Verifying an ATM Interface Connection Status

When the VP tunnel is configured correctly, the connection status displayed in the AutoCfgState shows the
word completed. You display this information by using the show atm interface command followed by the
ATM interface. Let's take a look at an example of the command:
CoriolisLS1010# show atm interface atm 3/0/2.2
Interface: ATM3/0/2.2
IF Status: UP
Auto−config: enabled
Port−type: vp tunnel
Admin Status: up
AutoCfgState: completed
