Setting the stack type parameter
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
Note: 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>.<virtualport 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>.<virtualport number>.
<value> Selects the type of signalling stack that will be used for the virtual
port.
