Chapter 4 DHCP Snooping Configuration
Note:
DHCP Snooping supports no link aggregation. If an Ethernet port is added into an
aggregation group, DHCP Snooping configuration on it will not take effect. When the
port is removed from the group, DHCP Snooping can take effect.
The DHCP snooping enabled device does not work if it is between the DHCP relay
agent and DHCP server, and it can work when it is between the DHCP client and
relay agent or between the DHCP client and server.
The DHCP Snooping enabled device cannot be a DHCP server or DHCP relay
agent.
You are not recommended to enable the DHCP client and DHCP Snooping on the
same device. Otherwise, DHCP Snooping entries may fail to be generated, or the
DHCP client may fail to obtain an IP address.
