Managing Virtual Ports

Avaya M770 ATM Switch User’s Guide

You can set the signalling stack type for a virtual port. The default signalling stack 
type is PNNI 1.0.
The signalling stack type can be:
•

UNI 3.0

•

UNI 3.1
Note, straight “IISP” is by default based on UNI 3.1 signalling.

•

UNI 4.0

•

IISP  3.0

•

IISP  3.1

•

PNNI 1.0

You must disable the virtual port before you can change or reset any virtual 

port parameters. For more information about how to disable a virtual port, see 
“Disabling a virtual port” on page 65.

To set the signalling stack type for a virtual port, use the

vport set

 

stacktype

 

command. 

Example:

M15-155s8:/>vport set profile 8.1.0 user

Parameters:

<vport 

id>

The virtual port in the form <slot>.<port>.<virtual port number>.

user

During signalling the virtual port will act as the user side of the 
connection.

network

During signalling the virtual port will act as the network side of the 
connection. The default signalling profile is “network”. 
However, on an inter-switch link, using IISP, one side of the link will 
have to be configured to “user” side. This does not apply when 2 M770 
ATM Switches are connected together which will automatically 
configure one side of the link to “user”.

Command:

M15-155s8:/>vport set stacktype <vport id> <value>

Example:

M15-155s8:/>vport set stacktype 8.1.0 UNI 3.1

Parameters:

<vport id>

The virtual port in the form <slot>.<port>.<virtual port number>. 

<value>

Selects the type of signalling stack that will be used for the virtual 
port.
