I have a Cisco 4500 switch that is giving me some issues. Hosts in the same VLAN on the same blade can not ping one another. They resolve layer 2 just fine. After the pings fail, each hosts shows up in the ohters arp table. There are a few VLANS that work just fine but a majority of them do not. For example VLANs 100-160 work perfectly. Those VLANs pull DHCP and get on the network with no issues. Most of the other VLANs will not pull DHCP. Even with static IP addresses they can not get on our network nor can they ping one another. Cisco TAC seems to think it is the Supervisor engine.
Any ideas what could be causing this issue?
