I'm hoping someone may have seen an issue we are having, or perhaps be able to help. We have MS410 switches running DHCP with dual uplinks to MS225s across a number of floors. We are running separate wireless and wired vlans on each floor. DHCP is working for all VLANs expect for one wired vlan. One device has been given a dhcp address some time ago, and continues to renew it's lease, but subsequent attempts are failing, with no IP address being assigned. Any devices given a static IP address within the DHCP scope connect without issue, the DHCP scope is hardly used so the scope is not full. The DHCP settings match the other scopes that are working correctly. It is as if the DHCP server is offering an address, but not getting a response from the client, but the same client will receive an IP address on any other vlan. I've tried making, and reverting, a small change to the dhcp settings to try and give the scope a kick - grasping at straws. Any suggestions or observations would be much appreciated.
