AV Line of Fully Managed Switches M4250 Series Main User Manual The Binding Configuration page displays. 6. In the Static Binding Configuration table, select the check box for the static binding. 7. Click the Delete button. The IPSG binding entry is removed from the database. 8. To save the settings to the running configuration, click the Save icon. IPv6 source guard interfaces You can configure IPv6 source guard (IPv6SG) on individual interfaces. IPv6SG is a security feature that filters IPv6 packets based on source ID. This feature helps protect the network from attacks that use IPv6 address spoofing to compromise or overwhelm the network. The source ID can be either the source IPv6 address or a combination of a source IPv6 address and source MAC address, referred to as a pair. The DHCP snooping bindings database, along with IPv6SG entries in the database, identify authorized source IDs. If you enable IPv6SG on a port on which DHCP snooping is disabled or on which DHCP snooping is enabled but the port is untrusted, all IPv6 traffic received on that port is dropped. In addition, IPv6SG interacts with port security (see Port security on page 567) to enforce the source MAC address in incoming packets. Port security controls how source MAC addresses are learned in the Layer 2 forwarding database (the MAC address table). If a port receives a frame with a previously unlearned source MAC address, port security uses IPv6SG to determine if the MAC address belongs to a valid binding. Configure IPv6 source guard on an interface You can configure IPv6 source guard on individual interfaces. To configure IPv6 source guard on an interface: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login page displays. 3. Click the Main UI Login button. The main UI login page displays in a new tab. 4. Enter admin as the user name, enter your local device password, and click the Login button. The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in. Manage Switch Security 619 Main User Manual
