I have Cisco Catalyst 4507. On WS-C4507E I created a few VLANs and with I have problem with one VLANs. When I add device in VLAN 150 this device take ip-address from DHCP server and after this host don't see other hosts in this or other VLANs. But after reload WS-C4507E all begin working well. I can't understand where is problem and what I have to do for deciding my problem.
Hmm, Is the host taking the IP that is configured on the SVI of the 4500? Is that host replying to ARPs that should be for the default gateway? Please post configuration and more information.
