ATM Conﬁguration

Settings

The Settings portion of the window contains a list box which displays information about each of the currently conﬁgured PVCs, as well as the ﬁelds used to conﬁgure new connections:

I/F	The device interface on which the PVC was conﬁgured.
VPI	Displays the Virtual Path Identiﬁer assigned to the
	connection; current versions of 9A128-01ﬁrmware allow
	values from 0 - 3. Virtual Path Identiﬁers are used to
	group virtual connections, allowing for channel trunking
	between ATM switches. Each VPI can be conﬁgured to
	carry many different channels (designated by VCIs)
	between two points.
VCI	Displays the Virtual Channel Identiﬁer assigned to the
	connection; allowable values are 0 - 1023 for each VPI.
	Each assigned VCI must be unique within its deﬁned
	VPI: for example, you can assign a VCI of 14 as many as
	four times: once with a VPI of 0, once with a VPI of 1, and
	so on. Remember, it is the combined VPI and VCI
	designations assigned to a channel that creates the
	grouping of virtual connections.
Encapsulation Type	Displays the method used to encapsulate LAN packets
	on the selected circuit. Current versions of 9A128-01
	ﬁrmware use 802.3 VC-based multiplexing for bridging
	protocols (designated VC MUX 802.3 Bridged); future
	versions will add support for ATM Forum LAN
	Emulation and Cabletron’s SecureFast Switching. You
	may also see some connections assigned a type of
	“other”; these are default connections that cannot be
	modiﬁed or deleted.
Status	Displays the current administrative status of the
	connection: enabled or disabled. In current versions of
	ﬁrmware, all connections are enabled by default, and
	cannot be disabled.
UpTime	The length of time the selected connection has been
	enabled.

NOTE

You can only view current connections; you will not be allowed to add new connections, delete existing connections, or modify existing connections, on 9A128-01’s with the ﬁrmware currently supported.
