I upgraded our 3560-48-ps switch from c3560-advipservicesk9-mz.122-35.SE5.bin to c3560-ipservicesk9.mz.122-55.SE4bin and is having issues now.
Since I upgraded to the new IOS our older machines on the network can no longer connect to the domain and is not getting an IP address
sh ip dhcp binding and sh ip dhcp conflict does not show any output, however all newer machines on the network received dhcp addresses without any problems and can connect to the network and internet.
For testing purposes I put the old IOS back on the switch and the older machines could connect again and received dhcp addresses.
No other changes were made to the config.
I did a comparison on Cisco's website and both IOS's support DHCP
Does anyone perhaps have any suggestions. Not sure why the new IOS would not give any output when I ran the commands.
older machines : Apollos and NCS (They all have XP service pack 2 with Intel 2.8 processors.)
