Frame Relay Data
Link Configuration
Use the following steps to configure the Frame Relay data link:
1
Add the Frame Relay data link.
add datalink frame_relay interface rm0/wan:1 enabled yes
2 Configure the following interface-level parameters:
set frame_relay on interface rm0/wan:1
access_rate [0-2048000]
management_type [ansi | itu | lmi | no_lmi]
mtu [260-2048]
Both ends of the Frame Relay link must be configured for the same
management type, otherwise the link is assumed to have failed.
3 Configure optional advanced configuration parameters.
set frame_relay on interface rm0/wan:1
error_theshold [1-10]
full_enquiry_interval [1-255]
monitored_events [1-10]
polling_interval [5-30]
The parameters in Table 55 do not usually need modification. They are
based on the management type configured in Step 2.
Table 55 Frame Relay Parameters
Parameter Description
access_rate Speed in bits per second of the Frame Relay access line.
management_type Type of LMI protocol used by the Frame Relay carrier:
■
ANSI - ANSI T1.617 Annex D
■
ITU - ITU Q.933 Annex A
■
LMI - LMI rev.1

issued.
monitored_events Sets the number of status polling intervals over which the
error threshold is counted.
polling_interval Number of seconds between LMI Status Inquiries.
