Configuring the 1-Port HSSI Network Module Chapter 3 Configuring with the Command-Line Interface To invoke ATM over a serial line, perform the following tasks in interface configuration mode: Task Command Specify the encapsulation method. encapsulation atm-dxi Map a given VPI and VCI to a DXI frame dxi map protocol address vpi vci address. [broadcast] Convert HSSI to Clock Master You can convert the HSSI interface into a 45-MHz clock master by performing the following task in interface configuration mode: Task Convert the HSSI interface into a 51.84-MHz clock master. Command hssi internal-clock Disable Fair Queueing Disabling fair queuing will dramatically improve fast switching rates over the HSSI. To disable fair queueing, perform the following task in interface configuration mode: Task Command Disable fair queueing. no fair-queue For more information about configuring HSSI interfaces, refer to the "Configuring Serial Interfaces" chapter in the Cisco IOS Release 11.3 Configuration Fundamentals Configuration Guide. Configuration Examples The following example shows how to configure a 1-port HSSI network module on a Cisco 3600 series router. Both sides of the network connection need to be configured: interface hssi 0/0 ip address 10.1.1.1 255.255.255.0 hssi internal-clock no fair-queue no shutdown interface hssi 1/0 ip address 10.1.1.2 255.255.255.0 hssi internal-clock no fair-queue no shutdown In this example: • The interface hssi command specifies a HSSI interface and changes the configuration mode from global to interface. • The ip address command assigns an IP address to this interface. • The hssi internal-clock command sets the HSSI clock source. 3-48 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
