■
Use to configure LMI counters and timers.
■
LMI counters and timers have configurable ranges that allow you to control the
state of the Frame Relay interface. In general, accept the default values for the
timers and counters, unless you need to modify them according to a special
arrangement with your customers.
■
Some commands have DTE and DCE versions. Use the dte version of the
command if the interface is operating as a DTE. Use the
dce version of the
command if the interface is operating as a DCE. Use both versions of the
command if the interface is operating as an NNI.
■
Use the frame-relay lmi-n391dte command to set the N391 full-status polling
counter. When you set this counter to a number, n , the n th request is a full-status
request. The range is 1–255 event messages. The default is 6 event messages.
■
Use the frame-relay lmi-n392dte or frame-relay lmi-n392dce command to set
the N392 error threshold counter, which specifies the number of errors within
N393 events that will place the interface in an operationally down state. The
range is 1–10. The default for the DTE version is 3. The default for the DCE
version is 2.
■
Use the frame-relay lmi-n393dte or frame-relay lmi-n393dce command to set
the N393 monitored events counter to specify the diagnostic window used to
verify link integrity. Detection of N392 errors within the window of N393 samples
places the interface in an operationally down state. The range is 1–10 events.
The default for the DTE version of the command is 4 events. The default for the
DCE version is 2 events.
■
Use the frame-relay lmi-t391dte command to set the T391 link integrity polling
timer interval between status inquiries issued by the DTE. The network checks
that the DTE polls within the verification interval, T392. The range is 5–30
seconds. The default is 10 seconds.
■
Use the frame-relay lmi-t392dce command to set the T392 polling verification
timer that specifies the maximum interval (in seconds) between the receipt of
status inquiries from the DTE equipment before it considers it as an error event.
The range is 5–30 seconds. The default is 15 seconds.
■
Example
host1(config-if)# frame-relay lmi-n391dte 20
■
Use the no version to remove the current setting and set the default.
