Incomplete ARP's on a Class C Subnet
From this morning we've had around 6 users complain that they are not getting a network connection. On further investigation the device is getting an IP address and can be pinged locally but is unable to get off the site.
On checking the ARP cache on the 3750 the devices not getting off the network all have Incomplete next to there addresses, I've flushed the cache a number of times and it still comes back incomplete.
The devices plug into a 2950 which is connected to a 3750 that does all the routing off the LAN and its from the 3750 that we cannot see the devices in question.
Any help would be much appreciated.
Thanks

try if you ping another computer from the same site the the problem in on the router..
but if you still wan to check the swicth , you can do that thru a console port or thru vlan. but to make it thru vlan you have yo had set the vlan1 password (that´s for administrative propose), and then check the port. to make sure it's no closed or blocked.
hope it can help
