client in a DNS.
• RANGE POOL: Set IPV6 address range to be assigned to DHCP client
• First/Second/Third DNS SERVER: Configures a DNS server that will be
used by a DHCP client.
• First/Second/Third NTP SERVER: Configures a NTP server that will be
used by a DHCP client.

Retrieving Number of DHCP Packets
To check the number of DHCP packets that the DHCP server receives, execute the ‘show
ip dhcp statistics’ command.
DHCP Relay
The DHCP relay forwards a DHCP packet received from a client through broadcast to the
DHCP server. Because it switches with the DHCP proxy, the DHCP relay is enabled when
the DHCP proxy is disabled.
The DHCP relay is working in the unit of interface. It is disabled in the ‘mgmt0’ and ‘lo’
interface. The DHCP relay is not working even when no IP address is configured in the
interface.
Configuration using CLI
The procedure of changing to the DHCP relay is as follows:
1 Go to the configure mode of the CLI.
WEC8500# configure terminal
2 Switch to the DHCP relay.
The relay and proxy are operating in the switching mode. If a proxy is not
used, it is operating in the relay mode.
WEC8500/configure # no ip dhcp-proxy enable
3 To check the configured DHCP information, use the ‘show ip dhcp-proxy’
command.
The DHCP IPV6 has no concept of a proxy. The procedure for
configuring a DHCPIPV6 relay is as follows:
4 Go to the configure mode in the CLI
WEC8500# configure terminal
5 Configure DHCP Relay IP.
DHCP IPV6 Relay agent can be set up to maximum of two.
Range of Timeout is 5s to 120s.
