[afnog] Router ethernet port hang

[Daniel Bwente]

Hello Moses

Seeing as the Router was OK prior to installing the Cards, the card hanging
after two to four days could point to a 'cumulative' something that builds
up over time till the card can't take it and hangs, try a *show
interface*on the Card's ports and compare the output  with the
*show interface* of what is connected to the Card, maybe there is a
discordance between the port settings between the device(s) the card is
connected to, What is the card connected to?

Cheers
