I have a 3Com 4500 switch that has four vlans and ports that are associated to each vlan. All four vlans had been working, but for some reason one vlan can no longer access the internet. When I plug a computer into port on switch associated to this vlan my local connection shows unauthenticated. Normally the local connect would show county. Local and the vlan would have access to the internet. Now it shows county. Local (unauthenticated) and I cannot access the internet. I have static IP addresses for these vlans.
All four were working and have worked for a year now just this one doesn’t. Why am I getting this unauthenticated error for local connection on this vlan?
