Diagnostics
Loopbacks
•
Local loopbacks loop data back to the local ATM-TE, through the local BPX switch. Remote
loopbacks loop data back to the local ATM-TE, through the whole connection route up to and
including the remote terminating card.
•
Local and remote connection loopbacks, and local port loopbacks, are destructive.
Card Tests
Connection Tests
•
The tstcon command is not supported. The tstdly command is used for connection continuity
testing.

Virtual Circuit Features
The following virtual circuit features are supported:
•
Connection Groups—Allows termination of up to 5000 (grouped) virtual circuits per BPX switch
that are supported for BXM ATM Band interworking connection types. The connection grouping
feature currently available on Frame Relay connections is expanded to include BXM ATM and
interworking connections.
•
FGCRA—Specifies that the Frame-Based Generic Cell Rate Algorithm is a firmware feature that
controls admission of cells to the network. It is configurable on a per-connection basis. It is a Cisco
WAN switching enhancement of the ATM-UNI standard Generic Cell Rate Algorithm. System
software allows configuration of FGCRA on a per-connection basis.
•
IBS—Specifies that the Initial Burst Size is an ATM bandwidth parameter that is used by firmware
to allow short initial bursts, similar to the Cmax mechanism on the IGX switch. It is configurable
on a per-connection basis.
