Appendix A: Accessing the Command-Line Interface

QoS Class

Enter 4 then select the ATM Quality of Service indicated by your service provider. The options are:

•1—CBR(constant bit rate)

•2—VBR-rt(variable bit rate real-time)

•3—VBR-nrt(variable bit rate non-real-time)

•4—UBR(unspecified bit rate is the default setting)

Peak Cell Rate

Enter 5 then type the QoS Peak Cell Rate (PCR) value supplied by your service provider. If you are not provided a PCR value, use the default. PCR is the maximum rate at which data is transferred on the line and measured in ATM cells per second. The valid range is 1-5500 cells per second. The default PCR is 5500.

Sustain Cell Rate

Enter 6 then type the QoS Sustainable Cell Rate (SCR) value supplied by your service provider. Use for CBR, VBR-rt, and VBR-nrt ATM QoS. SCR is the average rate at which ATM cells are transferred, measured in cells per second. The SCR must be less than the PCR. The valid range is 1-5500 cells per second.

Maximum burst size

Enter 7 then type the QoS Maximum Burst Size (MBS) value supplied by your service provider. Use with VBR-rt and VBR-nrt QoS. MBS is the maximum number of cells that can be transmitted at the peak cell rate. The MBS rate must be equal to or less than the PCR. The default MBS is 0.

Encapsulation

Type 8 then select the encapsulation type as indicated by the service provider. The options are:

•1—Llc Encapsulation (Logical Link Control) allows multiple protocols to be run over the session. This is the default encapsulation.

•2—Vcmux(Virtual Channel Multiplexer) encapsulation allows one protocol to be run over the session.

WAN DHCP Enable

Type 9 then select 1 to Disable or 2 to Enable DHCP client. Enabling DHCP client provides the capability where this session will automatically received an IP address
