Figure 1. Edit SNA Timers window

This window has the following choices:

Port Number

Select the 0 or 1 radio button.

Inactivity Timer/Ti (ms)

Range .24 - 90.0 seconds in .12 second intervals. If you enable the inactivity timer, the card periodically tests the viability of the network media. The timer setting applies to all clients on the target LAN, not to individual clients. The timer interval indicates how quickly a failure of the network media can be detected when the connection is quiescent.

Choose one of the following:

• Enabled
• Disabled

Response Timer/t1 (ms)

Range .20 - 51 seconds. The T1 timer clocks link events that require responses from clients on the network.

Acknowledgment Timer/t2 (ms)

Range .08 - 20.40 seconds. An OSA CHPID starts the T2 timer when it receives an I-Format LPDU and stops when it sends an acknowledgement.

Maximum I Frames Before Transmit Window/N3

Range 1 - 4. The maximum number of I-Frames that can be sent before an acknowledgement is sent.

Maximum Transmit Window/TW

Range 1 - 16. Maximum number of outstanding I-format link protocol data units (LPDU) before an acknowledgement has to be received.

Click OK when you are finished.
