• Have a Spanning Tree path between them
• Do not have any switch between them on the Spanning Tree path that has AMAP enabled
IPv4 Support
Internet Protocol (IP) is a network-layer (Layer 3) protocol that contains addressing and control informa-
tion that allow packets to be forwarded on a network. IP is the primary network-layer protocol in the Inter-
net protocol suite. Along with the Transmission Control Protocol (TCP), IP represents the heart of the
Internet protocols. IP is associated with several Layer 3 and Layer 4 protocols. These protocols are built
into the base code loaded on the switch and they include:
• Transmission Control Protocol (TCP)
• User Datagram Protocol (UDP)
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol (DHCP)
• Simple Network Management Protocol (SNMP)
• Telnet - client and server
• File Transfer Protocol (FTP) – client and server
• Ping
• Traceroute
• Address Resolution Protocol (ARP)
• Internet Control Message Protocol (ICMP)
• RIP I / RIP II
• ECMP
• Static routes
The base IP software allows you to configure an IP router interface, static routes, a default route, the
Address Resolution Protocol (ARP), the router primary address, the router ID, the Time-to-Live (TTL)
Value, IP-directed broadcasts, and the Internet Control Message Protocol (ICMP). In addition, this soft-
ware allows you to trace an IP route, display Transmission Control Protocol (TCP) information, and
display User Datagram Protocol (UDP) information.
The switch operates only in single MAC router mode. In this mode, each router interface is assigned the
same MAC address, which is the base chassis MAC address for the switch.
31-Bit Network Mask Support – Configuring a 31-bit netmask is supported to allow for a point-to-point
Ethernet network between two routers.
IPv6 Support
IPv6 (documented in RFC 2460) is designed as a successor to IPv4 and is supported on the OmniSwitch
6400. The changes from IPv4 to IPv6 fall primarily into the following categories:
