Con®guring the X.25 Network Interface

of packets that can be outstanding before requiring packet con®rmation. The default is 2. The window size can be negotiated down to 1 by the called DTE.

vSet Default Window

Default Packet Size

Speci®es the default requested packet size for SVCs. This value serves as the lowest negotiable packet size and must be equal to or less than the maximum packet size speci®ed with thenational set packet-sizecommand. The maximum default packet size is 4096 bytes. The default value for this parameter is 128 bytes.

vNational Set Packet Size Maximum

Maximum Packet Size

Speci®es the maximum negotiable packet size for SVCs. This value must be equal to or less than the maximum packet size speci®ed with the national set packet-sizecommand. The default value for this parameter is 256 bytes. The maximum value that can be con®gured for this parameter is 4096 bytes. This value is utilized in calculating the maximum frame size for this X.25 interface.

Circuit Idle Time

Speci®es the number of seconds that an SVC can be idle before it is cleared by the router. The range is 0 to 65365. The default is 30 seconds. A 0 (zero) speci®es that the circuit is never cleared by the router.

Maximum VCs

Speci®es the maximum number of circuits that are open to the same DTE address for a protocol. Refer to RFC 1356 for information on utilizing this parameter. The Valid range is 1 to 10. The default is 4.

The following are QLLC unique parameters:

QLLC response timer

The number of seconds to wait for a Q-response packet before retransmitting.

QLLC response count

The maximum number of times QLLC will retransmit. Upon exhausting this number of retries, the upper layer is noti®ed which may result in the circuit being cleared or reset by the router.

Accept Reverse Charges

Allows this protocol to override the setting of this National Personality parameter. This does not affect the National Personality parameter.
