Configuration Tasks; Implementation Information; Configure The System To Be A Dhcp Server - Dell Force10 C150 Configuration Manual

Implementation Information

• The Dell Force10 implementation of DHCP is based on RFC 2131 and RFC 3046.
• DHCP is available on VLANs and Private VLANs.
• IP Source Address Validation is a sub-feature of DHCP Snooping; FTOS uses ACLs internally to
implement this feature and as such, you cannot apply ACLs to an interface which has IP Source
Address Validation. If you configure IP Source Address Validation on a member port of a VLAN and
then attempt to apply a access list to the VLAN, FTOS displays the first line in
apply an ACL to a VLAN and then attempt enable IP Source Address Validation an one of its member
ports, FTOS displays the second line in
Message 1 DHCP Snooping with VLAN ACL Compatibility Error
% Error: Vlan member has access-list configured.
% Error: Vlan has an access-list configured.
• FTOS provides 40K entries that can be divided between leased addresses and excluded addresses. By
extension, the maximum number of pools you can configure depends on the on the subnet mask that
you give to each pool. FTOS displays an error message for configurations that exceed the allocated
memory.
• E-Series supports 16K DHCP Snooping entries across 500 VLANs.
• C-Series and S-Series support 4K DHCP Snooping entries.
• All platforms support DAI on 16 VLANs per system.

Configure the System to be a DHCP Server

Configure the System to be a DHCP Server
A DHCP server is a network device that has been programmed to provide network configuration
parameters to clients upon request. Servers typically serve many clients, making host management much
more organized and efficient.
The key responsibilities of DHCP servers are:
1. Address Storage and Management: DHCP servers are the owners of the addresses used by DHCP
clients.The server stores the addresses and manages their use, keeping track of which addresses have
been allocated and which are still available.
