DHCPv6 Snooping
– 376 –
◆ Set all interfaces connected to DHCv6 servers within the local network or fire
wall to trusted, and all other interfaces outside the local network or fire wall to
untrusted.
◆ When DHCPv6 snooping is enabled globally and enabled on a VLAN, DHCPv6
packet filtering will be performed on any untrusted ports within the VLAN
according to the default status, or as specifically configured for an interface.
◆ When an untrusted port is changed to a trusted port, all the dynamic DHCPv6
snooping bindings associated with this port are removed.
◆ Additional considerations when the switch itself is a DHCPv6 client – The port(s)
through which it submits a client request to the DHCPv6 server must be
configured as trusted.
Parameters
These parameters are displayed:
◆ Interface – Port or trunk identifier.
◆ Trust Status – Enables or disables an interface as trusted. (Default: Disabled)
◆ Max Binding – Sets the maximum number of entries which can be stored in
the binding database for an interface. (Range: 1-5; Default: 5)
◆ Current Binding – Shows the maximum number of entries which can be stored
in the binding database for an interface.
Web Interface
To configure the trust status and maximum bindings for DHCPv6 Snooping:
1. Click Security, DHCP Snooping6.
2. Select Configure Interface from the Step list.
3. Set any interfaces within the local network or firewall to trusted.
4. Set the maximum number of entries which can stored for an interface.
5. Click Apply
