# Configuring NSNA using EDM

Use the following procedure to globally enable or disable NSNA, and to view NSNA status information.

## Prerequisites

- You must enable SSH before you can enable Avaya SNA globally. For more information about SSH, see Configuring SSH on the 5000 Series switch for NSNA in Configuration — Security Avaya Ethernet Routing Switch 5000 Series (NN47200-501).

## Procedure steps

1. From the navigation tree, double-click Security.

2. In the Security tree, double-click NSNA.

3. In the work area, click the Globals tab.

4. Select the Enabled check box to globally enable NSNA.

   OR

   Clear the Enabled check box to globally disable NSNA.

5. In the toolbar, click Apply.

   Important

   It can take 2–3 minutes to globally enable/disable NSNA, especially on a fully populated stack.

## Variable definitions

Use the data in the following table to configure NSNA.

Variable | Value
--- | ---
Enabled | Enables or disables NSNA on the network access device.
NsnasConnectionState | Displays the status of the connection between the network access device and the NSNAS 4050.
NsnasInetAddressType | Displays the type of IP address used by the NSNAS 4050.
NsnasInetAddress | Displays the pVIP of the NSNAS 4050.
NsnasSendHelloInterval | Displays the time interval, in seconds, for the hello (healthcheck) messages sent by the NSNAS 4050 to verify connectivity with the network access device. The interval is configured on the NSNAS 4050. The valid configurable range for the interval is 60s (1m) to 64800s (18h). If there is no current connection between the network access device and the NSNAS 4050, the field displays a value of zero.
NsnasInactivityInterval | Displays the switch inactivity interval, in seconds, after which the switch enters status-quo mode. The switch inactivity interval is the hello (healthcheck) interval x the number of retries (deadcount) configured on the NSNAS 4050. If there is no current connection between the network access device and the NSNAS 4050, the field displays a value of zero.
NsnasStatusQuoInterval | Displays the status-quo interval time, in seconds for the current or last SSCP connection. The valid configurable range for the status-quo interval is 0 to 65535s (18h approx). If the solution has been configured so that no status-quo interval is used, the field displays a value of 65535. This means that the network access device does not move NSNA-enabled ports to the Red VLAN even though the connection between the NSNAS 4050 and the network access device may for each interrupted. If the NSNAS has disconnected and the status-quo interval timer is running, this value will reflect the remaining time, until the status-quo timer expires. Important A status-quo interval value of 0 indicates that the network access device will move NSNA-enabled ports to the Red VLAN immediately, when the connection between the NSNAS 4050 and the network access device is interrupted.
NsnasConnectionVersion | The version of the Nsnas Connection.
