SG 300 28 port not reusing expired dhcp lease bindings

[itscomputers]

I have an SG300 28 ports and I face an issue. The DHCP is full, expired lease bindings are not reused and the new clients don't get issued IPs. BIOS version 1.4.8.6. I have to manually delete the expired bindings every week.

Any ideas?

Upgrade to the latest release these firmwares were known for having DHCP issues , if it still persists move DHCP off that switch maybe to a server
sx300_fw-14106.ros

The release notes of sx300_fw-14106.ros do not refer to this issue. In any case i will try it and revert.

You could open a case with Cisco but they will point you to the latest release first anyway ,the release your on has DHCP bugs that are known , that doesnt mean there are not more too
