Monitoring MLFR

Use the commands in this section to display information about MLFR interfaces.

You can set a statistics baseline for an MLFR bundle or subinterface using the baseline frame-relay interface mlframe-relay command. Similarly, you can set a statistics baseline for an MLFR link with the baseline frame-relay multilink interface command. Use the delta keyword with the show commands described below to display statistics with the baseline values subtracted.

After you configure multilink Frame Relay, you can use the show frame-relay commands to view information about the multilink. For information about these commands, see Configuring Frame Relay.

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. Refer to the section show Commands in JUNOSe System Basics Configuration Guide, for details.

baseline frame-relay interface

Use to set a statistics baseline for the Frame Relay layer on MLFR bundles, Frame Relay interfaces, subinterfaces, and circuits.
Specify the keyword mlframe-relay and the name of the MLFR bundle to set a baseline for the Frame Relay statistics on an MLFR bundle.
The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
You cannot set a baseline for groups of interfaces, subinterfaces, or circuits. You must set baselines one at a time.
When baselining is requested, the time since the last baseline was set is displayed in hours:minutes:seconds or days/hours format. If a baseline has not been set, the message “ No baseline has been set” is displayed instead.
The regular interface statistics and LMI statistics for interfaces are subject to the same baseline timestamp. You cannot set separate baselines for these statistics.
Use the optional delta keyword with Frame Relay show commands to specify that baselined statistics are to be shown.
Examplehost1#baseline frame-relay interface mlframe-relay boston
There is no no version.
See baseline frame-relay interface.

baseline frame-relay multilinkinterface

Use to set a statistics baseline for MLFR links.
The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
When baselining is requested, the time since the last baseline was set is displayed in hours:minutes:seconds or days/hours format. If a baseline has not been set, the message “ No baseline has been set” is displayed instead.
The regular interface statistics and LIP statistics for interfaces are subject to the same baseline timestamp. You cannot set separate baselines for these statistics.
Use the optional delta keyword with Frame Relay show commands to specify that baselined statistics are to be shown.
Examplehost1#baseline frame-relay multilinkinterface serial 3/2
There is no no version.
See baseline frame-relay multilinkinterface.
