XS3800 IP Source Guard Lease time update issue.

Dear Chris,

Thank you very much for the proposed solution.

I would like to summarize. The XS3800-28 switch was configured as DHCP relay. VLAN 12 was used for access to DHCP server. IP renew messages was not processed by DHCP snooping when it was enabled only on user VLAN. Enabling DHCP snooping additionally on the VLAN 12 solved the issue.
