Support of DHCP functions by S series switches

5

For S series switches excluding the S1700, DHCP functions include DHCP server, DHCP relay, and DHCP client. The support for DHCP functions is as follows:
S series modular switches: Earlier versions of V200R005 do not support DHCP client, and other functions are supported by all versions.
S series fixed switches: V100R006C05 and later versions support DHCP client. The support for DHCP functions is as follows:
-V100R005: S2700 series switches do not support DHCP server and DHCP relay.
-V100R006: S2700 series switches do not support DHCP server and DHCP relay.
-V200R001: Only the S5700LI, S5700S-LI, and S5710LI do not support DHCP server and DHCP relay.
-V200R002: Only the S5700LI and S5700S-LI do not support DHCP server and DHCP relay.
-V200R003: Only the S2750, S5700LI, and S5700S-LI do not support DHCP server and DHCP relay.
-V200R005 and later versions: Only the S2720 switch in V200R006C10 does not support DHCP server, and other switches support all functions.

DHCP functions of S series switches
DHCP dynamically configures and uniformly manages network parameters of hosts on a TCP/IP network. DHCP provides the following functions: - Dynamic allocation: DHCP allocates an IP address with a limited validity period (called lease) to a client. This mechanism applies to hosts that temporarily connect to a network with fewer IP addresses than the total number of hosts and hosts do not need to permanently connect to the network. For example, this mechanism can be used to allocate IP addresses to laptops used by employees on business trips or mobile terminals in cafes. - Static allocation: Fixed IP addresses are assigned to specified hosts. This mechanism applies to hosts with special IP address requirements. For example, the file server of an enterprise needs to use a fixed IP address to provide services for extranet users. Compared with manual IP address configuration, DHCP static allocation prevents manual configuration errors and helps network administrators perform unified maintenance and management. DHCP can allocate other network parameters except for the IP address to hosts, including the DNS server address, routing information, and gateway address.

Do S series switches support the DHCP server polling function on a DHCP relay agent
When functioning as a DHCP relay agent, the S series switch excluding the S1700 supports the DHCP server polling function on a DHCP relay agent starting from V100R006C00. By default, the DHCP server polling function on a DHCP relay agent is disabled. You can enable the DHCP server polling function on a DHCP relay agent by configuring ip relay address cycle in the system view.

Support for the DHCP snooping location transition function on S series switch
S series switches (except S1700 switches) in V100R003 and later versions support the DHCP snooping location transition function, which is enabled by default.
