Hi,

since AOS Release 6.4.3 OmniSwitch supports an internal DHCP Server compliant with RFC 2131 based on Vital QIP 5.6.Consider the following when using the OmniSwitch Internal DHCP Server:
• Internal DHCP Server is supported only on the default VRF instance.
• Internal DHCP Server and DHCP Relay/Snooping are mutually exclusive; these features cannot run together in the default VRF instance.
• Only IPv4 is supported.
• Configuration on a per-VLAN basis is not supported.<---
• Configuring an IP interface is required.
• A maximum of 2K leases is recommended.
• If the dhcpd.conf file is edited, a restart of the DHCP Server (dhcp-server restart) is mandatory to reparse the modified configuration file.
• The larger the dhcpd.conf file size (file contains a lot of entries, such as with manual-dhcp), the more time it takes for the system to process the file.
• A DHCP server scope with Class A IP address subnets is not supported due to memory constraints.
• Configuring multiple DHCP server scopes for Class B IP address subnets will increase the amount of memory used. A single Class B scope reserves 2.3MB of memory.
