security {
    firewall {
        name name {
            rule rule-number {

Use this command to configure the firewall to accept or drop specified types of Ethernet packets.

After you define a firewall rule set with the Ethernet type, you must apply it to an interface as a packet filter by using the firewall-related interface commands. Until you apply a firewall rule set to an interface, the set has no effect on traffic destined for or traversing the system.

Use the set form of this command to define the Ethernet type to match.

Use the delete form of this command to delete the Ethernet type.

Use the show form of this command to display the Ethernet type for a firewall rule.
