How to use NIMPEE is basic end user introduction to NIMPEE with practical examples.
This guide assumes that initial network discovery is already done. For more details how to install, configure and run initial discovery please check First start article.
Scenario described below can be reproduced on NIMPEE demo servers.
Verifying the network
You can verify a lot of technologies and configuration parts with NIMPEE. You can simply go through technologies in NIMPEE menu (for example MAC table):
or quickly find particular technology you are interested in using search (for example MAC table):
Today's goal is to check all port channels in our network.
Step 1 - Find proper technology table
As described above we can simply browse NIMPEE menu and find particular technology table but in our case as we know exactly what we are looking for, search menu will be a better choice.
In the upper right corner click to search field and type your request. We are looking for port channels, ether channels or just link aggregation. Because I'm from Cisco world I would type in "port channel".
Search returns more results because there are more technology tables with port channels. We are interested in the last one in this case "Link Aggregation (LAG)/Portchannel/Etherchannel Member status table". Just click on it and we are there.
Step 2 - Look for malfunctions
For your convenience NIMPEE has predefined a lot of rules and reports. In our particular case port channels are colored green if everything is OK and other color is used when some malfunction is in place. You can easily sort the table by clicking the desired field in the header. In the example below we clicked on "Members (Status)".
We can instantly see that some port channels have interface down (blue color) or individual port (yellow color).
Pre-defined coloring rules can be fully customized. To do that click on predefined rule name in Reports box above the technology table which is "Port channel members state" in our case.
Now you can check and change predefined colorization rules.
Let's change coloring from blue to red when port in port channel is down:
