CLI Procedure for Configuring HTDS or CBR for Baud Rates Higher than 64K

Note: The following tasks must be performed on each Passport 4400 unit that is to support an attached device.

Determine the baud rate on the physical WAN port.

CLI> show wan parameter port operational entry 153

A table similar to the following appears:

Note: For Passport 4430, 4450, and 4455, the Logical Interface Module (LIM) name for the base module is always limA. The WAN and Expansion modules are numbered lim1 through lim4. For the Passport 4460, the LIM name for the base module is always base, Expansion modules are named exp1, exp2, and the PCMCIA module is named pcmciaExp.

The BaudRate parameter is the maximum limit for all traffic going through the physical link. This parameter must be set to a higher speed than the total throughput of all SVCs running through that physical link.

Determine the configured bandwidth on the netlink.

CLI> show msm dtelink operational table

A table similar to the following appears:

IfIndex	149
MaxSubChannelRange	63
DTEReceiverBW	128000
DCEReceiverBW	128000
DTEMaxFrameSize	80
DCEMaxFrameSize	80

The DTEReceiverBW and DCEReceiverBW parameters are the configured bandwidth on the netlink for both the PANL DTE and PANL DCE side. These should be configured to be greater than the total throughput of all SVCs running through that netlink.
