Polling Interval

The polling interval specifies the interval between status inquiry messages that the

router transmits. Status inquiry messages cause a network response in the form of

a link integrity verification message or full status message. Successful completion

of the request/response “handshake” verifies the status of the router/frame relay

network link. You should accept the default value, 10 seconds. If this value does

not match what the network requests, enter a value that is appropriate for your

network in the range of 5 to 30 seconds. The polling interval does not function if

you set the Management (Mgmnt) Type parameter to DLCMI None.

Full Enquiry Interval

The full enquiry interval specifies the interval between full status inquiry

messages that the router transmits. Full status inquiry messages cause the network

to send a full status report message, which lists all PVCs and their status (active or

inactive, and new or previously established).

The default value, 6, tells the router to send a full status inquiry every 6 polling

intervals. For example, with a polling interval of 10 and a full enquiry interval of

6, the router transmits a full status inquiry every 60 seconds. With a polling

interval of 20 and a full enquiry interval of 30, the router transmits a full status

inquiry every 10 minutes (600 seconds). The full enquiry interval does not

function if you set the Mgmnt Type parameter to DLCMI None.

Error Threshold and Monitored Events

Error threshold and monitored events together establish a criterion to evaluate the

quality of the router’s frame relay network connection. The error threshold is the

number of faulty status messages that must occur to terminate the connection.

Monitored events is the number of status message exchanges, within which

number those errors occur.
