DHCPv6 Snooping
– 381 –
■
Drop – Drops the client’s request packet instead of relaying it. (This is the
default policy.)
■
Keep – Retains the Option 82 information in the client request, and
forwards the packets to trusted ports.
■
Replace – Replaces the Option 37 remote-ID in the client’s request with the
relay agent’s remote-ID (when DHCPv6 snooping is enabled), and forwards
the packets to trusted ports.
Web Interface
To configure global settings for DHCPv6 Snooping:
1. Click IP Service, DHCPv6, Snooping.
2. Select Configure Global from the Step list.
3. Select the required options for the DHCPv6 snooping process and for the
DHCPv6 snooping information options.
4. Click Apply

DHCPv6 Snooping
VLAN Configuration
Use the IP Service > DHCPv6 > Snooping (Configure VLAN) page to enable or
disable DHCPv6 snooping on specific VLANs.
Command Usage
◆ When DHCPv6 snooping enabled globally and enabled on a VLAN, DHCPv6
packet filtering will be performed on any untrusted ports within the VLAN.
◆ When the DHCPv6 snooping is globally disabled, DHCPv6 snooping can still be
configured for specific VLANs, but the changes will not take effect until DHCPv6
snooping is globally re-enabled.
◆ When DHCPv6 snooping is enabled globally, and then disabled on a VLAN, all
dynamic bindings learned for this VLAN are removed from the binding table.
