We have a DHCP configured on Cisco 6513 switch and i found that one of the systems got the IP address as 10.155.0.6 which is nowhere related to our network.
- I checked the port and it is assigned the correct vlan of 105 as it should be
- however as it is getting different series of IP address other than 105 i have tried by disabling and enabling the port.
- Once i did that i immediately got the correct IP address of 105 series and the issue got resolved.
My question is why did the system acquired the IP address which is nowhere configured on our DHCP server and what are the possibilities and what should i check on the switch so that it will not be repeated again.
Waiting for your quick replies
Thanks in advance.
