Refreshing MRP Topology data
To refresh the MRP Topology data, click Refresh.
The MRP topology data syncs up with the data in the Management application server (not the
switch). If you make MRP changes on the switch using the CLI, the Management application server
uses the received traps to sync up the data. When the Management application receives traps,
data collection for that specific object begins and once collection is complete the Management
application server database is updated with the data. Note that data collection usually takes 2-3
minutes to finish depending on the network connectivity. However, data collection may take longer
when network connectivity is slow or the switch is far away.
You can verify received traps through the Master Log. If no traps are received, data collection is
triggered by the next lazy poll cycle. The lazy poll cycle is based on the configured network size
(small = every 5 minutes; medium = every 15 minutes). The Management application server polls
data collection from the switch and then updates the database.
