7.3 Configuring a Static MAC Address Entry
A static MAC address entry specifies an outbound interface for packets destined for a specified
MAC address. Static MAC address entries protect the S7700 from MAC address attacks.
Applicable Environment
You can configure a static MAC address entry if an interface is connected to an upstream device
or a server, as shown in Figure 7-1. Attackers may set the source MAC address of packets to
the server MAC address and send the packets to the Switch to intercept data of the server. To
protect the server and ensure communication between users and the server, you can configure a
static MAC address entry in which the destination MAC address is the server MAC address and
the outbound interface is the interface connected to the server.
