The line will come up and you can verify connectivity with by executing "ping YY.YY.YY.YY". Now, load up the line a little bit using the command "ping -f YY.YY.YY.YY" and wait about four minutes. Around that time, the router will show the line is up but the line protocol is down and the PC will have two messages displyed on it rapidly. The two lines look like this: ar0: Receive error chan 0, stat ff msci st3 3, rxhind 410, cda f, eda 4ff0. ar0: eat pkt 1977 loop, cda 0xd1bda00f, rxdesc 0xd1bdf004, stat ff. Note that this same box with the Emerging Technologies Sync card and their driver. Unfortunately, they don't support IPv6 and I need that to work for me under FreeBSD >Fix: >Release-Note: >Audit-Trail: >Unformatted:
