Interfaces re-indexed

We had a 7206 router with a 4 port serial port adapter reboot over the weekend and when it did, the serial ports were reindexed according to our monitoring software. Not a big deal. Just mostly curious as to why this might happen.

Re: Interfaces re-indexed

It happens on reboot because the interfaces come up in a different order. You can put this in your config to keep them persistent.
