Con®guring Frame Relay Interfaces

If you want to use a line speed greater than 2048000, you can only do this on:

vinterface 1.

vport 1 of a 4-port WAN concentration adapter.

vports 1 and 5 of an 8-port WAN concentration adapter.

The other WAN ports must be clocked at 64 Kbps or less.

lmi-type [rev1 or ansi or ccitt]

Sets the management type for the interface. See ªEnabling Frame Relay PVC Managementº on page 403 for details on setting Frame Relay management. The default is type ansi enabled.

n1-parameter count

Con®gures the number of T1 timer intervals which must expire before a complete PVC status enquiry is made. Count is the interval in the range 1 to 255. The default is 6.

n2-parameter max#

Con®gures the number of errors that can occur in the management event window monitored by the n3-parameter before the Frame Relay interface resets. Max# is a number in the range 1 to 10. The default is 3. This parameter must be less than or equal to the n3-parameter or you will receive an error message.

n3-parameter max#

Con®gures the number of monitored management events for measuring the n2-parameter. Max# is a number in the range 1 to 10. The default is 4.

p1-parameter max#

Con®gures the maximum number of PVCs supported by the Frame Relay interface. This includes active, inactive, removed, and congested PVCs. Max# is a number in the range 0 to 992. The default is 64. 0 (zero) implies that the interface supports no PVCs.

t1-parameter time

Con®gures the interval (in seconds) between sequence number exchanges with Frame Relay management. The management's T2 timer is the allowable interval for an end station to request a sequence number exchange with the manager. The T1 interval must be less than the T2 interval of the network. Time is a number in the range 5 to 30. The default is 10.

transmit-delay #

Allows the insertion of a delay between transmitted packets. The purpose of this command is to slow the serial line so that it is compatible with older, slower serial devices at the other end. It can also prevent the loss of serial
