DS3
Function: Specifies the appropriate MIB for the local management interface (LMI) to use,
as long as you enable LMI and configure SMDS or frame relay across the HSSI
interface. The HSSI driver does not support the DS1 or DS3 MIB. Rather, the
external DCE (for example, a DL3200 SMDS CSU/DSU from Digital Link)
may provide MIB support.
Instructions: Select a DS1 MIB (specified by RFC 1232) or a DS3 MIB (specified by RFC
1233), depending on the carrier services the attached DCE provides (DS1 at
1.54 MB/s, or DS3 at 44.736 MB/s).
MIB Object ID: 1.3.6.1.4.1.18.3.4.7.1.1.13
Parameter: External Clock Speed
Path: HSSI Connector > Edit Line > Edit HSSI Parameters
Default: 46359642 (44.736 MB/s)
Options: 307200 to 52638515
Function: Specifies the bandwidth that the HSSI channel provides.
The HSSI specification requires that the DCE provide a transmit clock that
times data transfer across the DTE/DCE interface. The value you specify for
this parameter does not actually affect hardware initialization. Certain routing
protocols use this parameter value for route selection.
Instructions: Specify a value equal or close to the data transmission rate across the HSSI
channel.
MIB Object ID: 1.3.6.1.4.1.18.3.4.7.1.14
