882.0. "CBR PVC bandwidth?" by TKOV51::HAYAKAWA (Kouhei Hayakawa, NPB/MS, Osaka HUB6F) Tue Apr 01 1997 08:41

	I noticed strange behavier of GIGAswitch/ATM.
	I created CBR PVC allocated 3Mbps by "pvc -s" command.
	When I confirmed the PVC by "pvc -a" command, the PVC was allocated 
	4Mbps. Why...??? Is it bug?

Regards,
Kohei

	The firmware was V2.1.1 and the linecards were QLC V1.5.

	We swapped to the QLC V2.0 and V2.1.3 firmware last week, 
	but same behavior...
