DESCRIPTION
adconfig is a tool to display and modify the current configuration of an ATM
device. If no action is indicated for the specified device, the configuration infor-
mation for the device is displayed.
The physical media device (PMD) configuration displayed includes the current
framing used, the device clock source, the loopback state, the state of frame and
stream scrambling, and the cell insertion type.
OPTIONS
-p Specifies the number of least-significant bits to match in the VPI field of the
ATM cell header. The number of VCI bits is computed automatically based
upon the number of VPI bits specified and the total number of VPI/VCI bits
supported by the adapter.
-l Enable/Disable PMD internal loopback mode.
-f Set PMD framing type to either SONET or SDH.
-i Set PMD to insert idle cells (ITU-T standard) or unassigned cells (ATM Forum
and ANSI standard).
-c Set PMD clock source to external or internal.
RESTRICTIONS
It is not possible to set the number of VPI bits on 200E series adapters.
NOTES
Modifying PMD parameters may cause communication problems. The parame-
ters must agree with the parameters chosen at the far end or intermediate
switching module.
