Interface ordering an port-channels #37

Open dgjustice opened 3 years ago

dgjustice commented 3 years ago

Environment

@samuel-odinware pointed out that Arista puts port-channels at the head of the list when issuing a "show run" command. This is a potential problems when creating config diff's. I jumped on a Catalyst 9k (Cisco IOS XE Software, Version 17.03.03) in Cisco's sandbox and observed the same behavior. I will try to take a look at a fix early next week, but I wanted to raise an issue in case others are using this function.

Thanks, I secretly always presumed there will need to be "configurable" patterns as different vendors will order differently. I really didn't have a good idea how to tackle our what they differences actually are, but I think something we should consider.
