Configuring Virtual Ports on the PathBuilder S24x, 26x, and 27x Switch

Introduction	You have to configure a virtual port for each connection between the remote nodes
	and the PathBuilder S24x, 26x, and 27x switch.
How to...
	Follow these steps to configure virtual ports between the remote nodes and the
	PathBuilder S24x, 26x, and 27x switch.

	1	From the CTP Main menu, select	The Ports menu appears, as shown

	3	Enter X25 for an X.25 connection or	The standard port parameters for

	5	Perform a Node boot.	This implements the configuration
			changes you made.
Booting Virtual
	Boot a virtual port by entering the virtual port number and issuing a port boot
Ports	command. Booting a virtual port brings down SVCs associated with that virtual port,
	but does not affect the operation of the T1 or E1 port, or of any other virtual ports.
Enabling/ Disabling
	Enabling or disabling a virtual port has no effect on a T1 or E1 port or other virtual
Virtual Ports	ports. However, disabling a T1 or E1 port makes all associated virtual ports unusable.
	Enabling a T1 or E1 port makes all associated virtual ports usable; their SVCs can be
	established. Virtual ports previously disabled via the disable port command remain
	disabled.
Port Speed
	Port speed for virtual ports is set from the DS0 Rate parameter in the Virtual Ports
	Mapping Table. You can set the rate of speed for traffic at 56k or 64k. See the
	“Configuring Virtual Port Mapping Table” section on page 5-20for more details.
