Table 1-7 shows the various ways you can set these parameters, and the effect

each combination has on disconnecting SVCs.

For instructions on setting these values for the inactivity parameters, see “Setting

Inactivity Values for SVCs” on page 5-22.

Note that a protocol priority filter configured with a no-reset action affects the

operation of the inactivity timer. Normally the inactivity timer resets when the

inactivity mode is set to Both or Both Directions, Either or Either Direction, or

Transmit Only or Outbound. However, if the data transmitted over an SVC

matches a protocol priority filter with a no-reset action, the inactivity timer will

not reset. Instead, the SVC may disconnect even though data is transmitting.

Managing Routing Information Protocol (RIP) and Inactivity Timing

RIP is a mechanism that IP and IPX use to inform network devices of routing

topology changes. IP and IPX let you control the frequency and destination of RIP

packets. Because RIP packets can affect how the router establishes and

disconnects frame relay SVCs, the software controls how RIP interacts with the

frame relay SVC inactivity timer and the inactivity timer mode. For more

information, see Appendix B, “RIP Management for Frame Relay SVCs.”
