Graph LLDP Transmission Statistics

Use this procedure to view the LLDP transmission (TX) statistics. You can also view the statistics graphically.

About this task

LLDP operates at the port interface level. Enabling FA on a port automatically enables LLDP transmission and reception on that port. It also enables traffic tagging and disables spanning tree on that port.

Enabling FA on an MLT enables LLDP transmission and reception on all ports in that MLT. 

Note

Note

When a port is removed from an MLT, LLDP transmission on that port stops and spanning tree is enabled. Any I-SID-to-VLAN mappings on that port are removed, if not already learned on any other port in the MLT. This also causes the Switched UNI I-SID to be deleted from the MLT. However, if the mappings are learned on another port on the MLT,the Switched UNI I-SID continues to exist for that MLT.

For ports in an LACP MLT, when FA is enabled, tagging is enabled on all ports in the LACP MLT. The consistency check for FA is based on key membership. If all ports with the same key do not support FA, FA is not successfully enabled on those ports.

Note

Note

If a slot is removed from the switch chassis, the statistics are not displayed on the slot ports. When the slot is inserted back again, the statistics counters are reset.

Procedure

  1. In the navigation pane, expand Configuration > Serviceability > Diagnostics > 802_1ab.LLDP.
  2. Click the TX Stats tab.

    The system displays the transmission statistics.

  3. To view the transmission statistics graphically for a port:
    1. Select a row, and click Graph.

      The system displays the TX Stats-Graph,<port-number> tab.

    2. To view the graph, select one of the parameters, and click the appropriate icon on the upper-left corner of the menu bar to draw a line chart, area chart, bar chart or a pie chart.
  4. To clear the existing counters, and fix a reference point in time to restart the counters, click Clear Counters.
  5. To export the statistical data to a file, click Export.
  6. To fix a poll interval, select an appropriate value from the Poll Interval drop-down list.
