The frame header settings are configured.
Configuring the LMI Settings
Local Management Interface (LMI) is a signaling mechanism often used on
frame relay networks to communicate information about the status of a network
connection. With the Frame Relay testing option, the E1/Datacom Tester can
monitor and emulate LMI signals on UNI-user, UNI-network, and NNI inter-
faces for the following LMI types:
– Annex D (ANSI T1.617)
– Annex A (ITU-T Q.933)
– LMI Rev 1
The E1/Datacom Tester can capture LMI messages, decode them, and then
display them in the Trace result category. Other LMI link results include the LMI
type, message count, errors, and timeouts. For more information about LMI
results, see “LMI results” on page 100.
To specify LMI settings
1 If you haven’t already done so, launch the Frame Relay application (see
“Launching the Frame Relay application” on page 64).
2 On the Configuration menu, select FR LMI Settings, and then specify the
following settings:
Lng Frm Rx
Thresh
Enter a value, from 5 to 9999 bytes, to indicate the long
frame receive threshold.
The
E1/Datacom Tester will maintain a count of
received frames that exceed the specified threshold.

Setting Parameters
Type Select the type of local management interface (LMI):
– Off
– T1.617 Annex D
– Q.933 Annex A
– LMI Rev 1
– Auto
Status Poll Time Enter a value, from 5 to 30, to indicate the status poll
time in seconds.
Full Poll Time Enter a value (n), from 1 to 255, to indicate that the
E1/
Datacom Tester
should perform a full status poll time
every nth poll cycle. For example, if you enter 4, the
E1/Datacom Tester will perform a full status poll
every 4th time.
