OmniSwitch 6400 switches support hardware-based IPv6 routing.

Note that the switch operates only in single MAC router mode. In this mode, each router VLAN is assigned

the same MAC address, which is the base chassis MAC address for the switch

IP DoS Filtering

By default, the switch filters the following denial of service (DoS) attacks, which are security attacks

aimed at devices that are available on a private network or the Internet:

• ARP Flood Attack

• Invalid IP Attack

• Multicast IP and MAC Address Mismatch

• Ping Overload

• Packets with loopback source IP address

IP Multicast Switching (IPMS)

IP Multicast Switching is a one-to-many communication technique employed by emerging applications

such as video distribution, news feeds, conferencing, netcasting, and resource discovery (OSPF, RIP2, and

BOOTP). Unlike unicast, which sends one packet per destination, multicast sends one packet to all devices

in any subnetwork that has at least one device requesting the multicast traffic. Multicast switching also

requires much less bandwidth than unicast techniques and broadcast techniques since the source hosts only

send one data stream to the ports on which destination hosts that request it are attached.
