Viewing the Configured WAN Protocol
The WAN Protocol parameter indicates which WAN protocol is enabled on a
HSSI circuit. However, do not change the current value.

Setting the Transmission Interface
You can select the appropriate MIB for the local management interface (LMI) to
use, provided you enable LMI and configure SMDS or frame relay on the HSSI
interface. Select one of the following MIBs, depending on the carrier services that
the attached DCE provides:
• DS1, at 1.54 MB/s (specified by RFC 1233)
• DS3, at 44.736 MB/s (specified by RFC 1232)
The HSSI driver enables the DS1 MIB by default, but provides no support for
either the DS1 or DS3 MIB. Rather, the external DCE (for example, a DL3200
SMDS CSU/DSU from Digital Link) may provide MIB support.
Using the BCC
media
variable
For example:
hssi/2/1# media ds1
hssi/2/1# media ds3
Caution:
Changing the WAN protocol does not reconfigure the interface, and
could disable it.
