3Com 812 manual Disable vc Internet, Set vc Internet sendpassword testpassword, Enable vc Internet

Remote Site Management 6-3

		For example, if you want to change the PPP authentication password to
		testpassword for a profile called Internet you would do the following:
	disable vc Internet
	set vc Internet send_password testpassword
	enable vc Internet
Configuring Network	A Network Service defines the data encapsulation and protocol characteristics for
Service Information	the connection between the OfficeConnect Remote 812 and the remote site. The
	OfficeConnect Remote 812 supports two types of Network Services: PPP and RFC
	1483. The OfficeConnect Remote 812 and the remote site must both use the
	same Network Service in order for a connection to established and maintained.
	For PPP, the authentication name and password must be provided to allow the
	connection to be established. The OfficeConnect Remote 812 supports both PAP
	and CHAP authentication.
	￿	To set up a profile for PPP, use the following commands:
	set vc <vc name> network_service ppp
	set vc <vc name> send_name <authentication name >
	set vc <vc name> send_password <authentication password>
		RFC 1483 does not support any type of authentication. Therefore, to set up a
		profile for RFC 1483 you simply configure the Network Service using the
		command:
	set vc <vc name> network_service rfc_1483
Configuring ATM	The ATM parameters are supplied by your service provider. These parameters
Information	consist of:
	￿		ATM VC information
		￿ATM Category of Service parameters
	ATM allows for permanent connections (PVCs) and switched connections (SVCs).
	For a PVC, the required VC information parameters consist of the Virtual Path
	Identifier (VPI) and Virtual Channel Identifier (VCI).
	The VPI/VCI uniquely specify the path to the remote site and are placed in the
	ATM cell header that is used to route each cell to the remote site.
	Two￿		VC profiles with the same VPI and VCI can not be enabled simultaneously.

You may encounter this situation if you want to login to the same remote site with different PPP authentication parameters. You should disable all profiles using the same VPI/VCI and then enable the one that should be active.

For SVCs, there is not a fixed VPI/VCI. Instead, a destination address is used to set up a path through the ATM backbone network when the connection is to be established.
