Configuration Tasks
Perform the tasks in the following sections to configure a HSSI interface. The first task is required; the
remaining tasks are optional.
• Specify a HSSI, page 3-47
• Specify HSSI Encapsulation, page 3-47
• Invoke ATM on a HSSI Line, page 3-47
• Convert HSSI to Clock Master, page 3-48
• Disable Fair Queueing, page 3-48
Specify a HSSI
To specify a HSSI and enter interface configuration mode, perform the following tasks in global
configuration mode:
Specify HSSI Encapsulation
The HSSI supports the serial encapsulation methods, except for X.25-based encapsulations. The default
method is HDLC. You can define the encapsulation method by performing the following task in interface
configuration mode:
For information about PPP, see the “Configure SLIP and PPP” chapter of the Cisco IOS Release 11.3
Access Services Configuration Guide and the “Configure PPP for Wide-Area Networking” chapter of
the Cisco IOS Release 11.3 Wide-Area Networking Configuration Guide.
Invoke ATM on a HSSI Line
If you have an ATM DSU, you can invoke ATM over a HSSI line by mapping an ATM virtual path
identifier (VPI) and virtual channel identifier (VCI) to a DXI frame address. ATM-DXI encapsulation
defines a data exchange interface that allows a DTE (such as a router) and a DCE (such as an ATM DSU)
to cooperate to provide a User-Network Interface (UNI) for ATM networks.
