View LLDP Transmission Statistics
Use this procedure to view the LLDP transmission 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
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. If however, the mappings are learned on another port on the MLT, then 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.
Procedure
- In the navigation pane, expand .
- Select LLDP.
- Select the TX Stats tab.
- Optional:
To view the transmission
statistics graphically for a port:
- On the TX Stats tab, select a row, and then select Graph.
- To view the graph, select one of the parameters, and then select the appropriate icon on the top left of the menu bar to draw a line chart, area chart, bar chart or a pie chart.
- Select Refresh Counters to clear the existing counters, and fix a reference point in time to restart the counters.
- Select Export to export the statistical data to a file.
- To fix a poll interval, select an appropriate value for Poll Interval.
