Configure the Stratix 5900 Services Router
Chapter 3
Internet (WAN): User Specified Encapsulation
The User Specified Encapsulation window lets you configure a WAN interface
when you are specifying the encapsulation.
Table 7 - WAN Interface Parameter Descriptions
Item
Description
Status Icon and
Enable or Disable
Button
The Status and Enable or Disable icons are available to edit an initial configuration. The Up arrow
icon indicates the interface is up. The Down arrow icon indicates the interface is down.
•
If a selected interface is enabled, you can click Disable to shut down the interface.
•
If a selected interface is shut down, you can click Enable to activate the interface.
Encapsulation
These are the encapsulations available if you have an ADSL, G.SHDSL, or ADSL over ISDN
interface.
Virtual Path
Identifier
Enter the Virtual Path Identifier (VPI) value obtained from your service provider or system
administrator. The VPI is used in ATM switching and routing to identify the path used for a
number of connections.
Virtual Circuit
Identifier
Enter the Virtual Circuit Identifier (VCI) value obtained from your service provider or system
administrator. The VCI is used in ATM switching and routing to identify a particular connection
within a path that it can share with other connections.
Address Type List
Choose one of the following:
•
Static IP Address—If you choose static IP address, enter the IP address and subnet mask or
the subnet bits in the fields provided.
•
Dynamic (DHCP Client)—If you choose Dynamic, the router leases an IP address from a
remote DHCP server. Enter the name of the DHCP server that assigns addresses.
•
IP Unnumbered—Choose IP Unnumbered if you want the interface to share an IP address
that has already been assigned to another interface. Then, choose the interface whose IP
address you want the interface that you are configuring to use.
•
Easy IP (IP Negotiated)—Choose Easy IP (IP Negotiated) if the router obtains an IP address
by PPP/IPCP address negotiation.
IP Address for
Remote Connection
in Central Office
If you are configuring a G.SHDSL connection, enter the IP address of the gateway that connects
to this link. This IP address is supplied by the service provider or network administrator. The
gateway is the system that the router must connect to access to the Internet or to your
organization’s WAN.
Enable Multilink
PPP
Check this check box if you want to use Multilink Point-to-Point Protocol (MLP) with this
interface. MLP can improve the performance of a network with multiple WAN connections by
using load balancing functionality, packet fragmentation, bandwidth-on-demand, and other
features.
Encapsulation
Description
PPPoE
Provides Point-to-Point Protocol over Ethernet encapsulation. An
ATM subinterface and a dialer interface are created when you
configure PPPoE over an ATM interface. These logical interfaces are
visible in the Summary window.
The PPPoE option is disabled if your router is running a release of
Cisco IOS software that does not support PPPoE encapsulation.
PPPoA
Provides Point-to-Point Protocol over ATM encapsulation (AAL5
SNAP, and AAL5 MUX). The PPPoA option is disabled if your router is
running a release of Cisco IOS software that does not support PPPoA
encapsulation.
RFC 1483 routing
with AAL5 SNAP
This option is available when you have selected an ATM interface.
An ATM subinterface is created when you configure an RFC 1483
connection. This subinterface is visible in the Summary window.
RFC 1483 routing
with AAL5 MUX
This option is available when you have selected an ATM interface.
An ATM subinterface is created when you configure an RFC 1483
connection. This subinterface is visible in the Summary window.
