As usual use at own risk! <\/p>\n
This may not apply to many people but I have an instance where we use DLMP which I really like. However one weakness I have in my environment if someone screw up a VLAN port configuration on a switch you may have serious networking issues and not understand what is happening. DLMP is not going to disable a port in an aggregation because there is link and it does not know if VLAN's are set or not. So I wrote a quick script I may play with more later to improve but this already helps with speeding up testing. Time is something you may not have a lot of when you have intermittent and very odd network behavior.<\/p>\n
And of course you will need to take these ports you want to test out of the aggregation for testing and add back in if you need to.<\/p>\n
Let me know if anyone find a better way for example DLMP built-in test or testing at a lower level in the networking model etc.<\/p>\n
