Hi all. I have a Catalyst 1900 behind a 1750 router. Users complain about their applications being dropped throughout the day. The switch doesn't stop responding to ping. The users usually reboot their computers and the issue is resolved. Could this be a flapping port?
The weird thing is port 0/8 shows up, but does not show up as plugged in when using the show mac-addresst table. Can anyone help me troubleshoot this issue?
