Configuring One-To-One Vlan Mapping - 3Com S7906E Configuration Manual

Enable the dynamic address binding support of IP Source Guard to filter packets received on a port
based on the source IP address and MAC address bindings created dynamically to prevent illegal
packets from passing through the port. For information about this feature, refer to IP Source Guard
Configuration in the Security Volume.
To save system resources, disable user bindings recording on the DHCP snooping trusted ports
that forward DHCP packets. For information about this feature, refer to DHCP Configuration in the
IP Services Volume.
