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.

ImportantImportant

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.
