Frame Relay on Contivity Secure IP Services Gateway

ANSI T1.617D provides user-side management services as specified in Annex-D to ANSI standard T1.617-1991. This is the default value.

CCITT Annex A provides user-side management services as specified by the ITU-T (formerly CCITT).

Configuring management type using CLI

To specify the link manager type, navigate to the serial interface and enter:

Frame-relay lmi-type <lmi-type>

<lmi-type> can be:

ANSI for ANSIT1.617 Annex D service. ilmi for Rev. 1 LMI.

none for no management service. q933a for CCITT Annex A service.

Monitoring the connection

You can monitor the status of your frame relay network connection by setting the time intervals for the CES to send messages that verify the integrity of the link

Polling interval

The polling interval specifies the amount of time between status inquiry messages that the CES transmits. Status inquiry messages cause a network to respond with a link integrity verification message or full status message. Successful completion of the request/response “handshake” verifies the status of the CES/frame relay network link.

The default polling interval is 10 seconds. If this value does not match what the network requests, specify a new value in the range of 5 to 30 seconds.

Configuring polling interval using CLI

To configure the polling interval, navigate to the serial interface and enter:

Frame-relay lmi-t391dte <integer>

<integer> is the polling interval, from 5 to 30 seconds. The default is 10.

Full enquiry interval

The full enquiry interval specifies the interval between full status inquiry messages that the CES 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 full enquiry interval value, 6, tells the CES to send a full status inquiry every 6 polling intervals. For example, with a polling interval of 10 and
