does anyone know if it is possible to identify which port of an lag interface is used?
Or how to test/calculate it?
On Cisco devices I know it is possible, and you can enter source/destination pair and it shows the resulting hash and link.
I did noch find anything like this for the Aruba-CX...
I want to compare if two different destination IPs tooks the same path between source and destination.One VM sends many TCP Retransmit / Dup ACK etc, and an other VM on the same host and switch interface (no lag yet) does not.I guess it is a software/VM problem, but to be sure I want to check if there is a difference which links are used in the network.
Thanks and kind regards
Hi Vincent,1. Thats bad, why cant aruba do such simple things?2. That was not the question. I was looking for the switch path (between source and destination switch). I know which ports on the edge sites to the server and client are used.3. That even was not the question. Of course that is configurable (L2/L3/L4, but not L3+L4). But It does not help to identify which link a specified traffic flow goes.
That means troubleshooting is very difficult, as I can't say which switch interfaces are traversed by a specific traffic flow.
And as I cannnot filter mirrrored traffic, mirroring is not an option... 100G Uplink Ports -> 1G Laptop LAN Port...
I apologize if it sounds rough to you, That was not my intend. But the troubles with aruba cx are getting more and more and migration has stopped, and the tac...
I will contact our dealer and representative, and parallel i opened a new idea in the innovation zone. But the activity and feedback there is.... not worth to mention.
Have a nice day!
And if someone does have a idea or a hidden command (cli or shell) to get the needed information, that would be helpful.
