Just remember that "Serial0 is up" refers to Layer 1 and "Line Protocol is
down" refers to Layer 2.

Subject:        Serial0 is up, line protocol is down!

Hello to All,

If Serial0 is up, line protocol is down, then what should I check? Give me
as many answers as you can.

BTW what  is the line protocol? is it a network protocol like ip, ipx? or is
it the data link layer protocol?

Omer
