I have a switch 4500 as a Core and dhcp server. In this I have a dhcp pool for the vlan 111.
I have an other switch, 3560. In this I have one port assigned to the vlan 111. When I connect a computer to this port, the computer get a ip, but I can ping the gateway. I look for the computer's mac address with "sh mac address-table" command and I find the mac with the port, but if I look for the same mac in the "core" with the "sh ip dhcp bind" command, I realize that the mac is diferent:
access(config-if)#do sh mac add | include Gi0/1
111 2c41.380f.60cf DYNAMIC Gi0/1
core0#sh ip dhcp bi
192.168.111.124 012c.4138.0f60.cf Oct 24 2013 12:14 AM Automatic
the problem is only with two computers in all the ports of this switch, but if I connect the same computer in other switch in the same LAN it works without problems.
Do you have any idea??
I think the dhcp pool is properly configured because with others computers in other port with the same vlan works perfect!!!
