Redundancy/Failover

OpenWare includes a number of features which provide failover

and redundancy support in the event that links fail and the network

needs to automatically reconfigure or failover to redundant links.

• MSTP(MultipleSpanningTree)

– Spanning Tree Protocol is used to provide and manage redun-

dant paths through a network. It prevents loops being formed

and reconfiguring the network if a link becomes unavailable.

MSTP is the latest version of this protocol, and allows for

different trees to exist over complex networks, segmenting

a network into separate regions and using multiple VLANs

to further segment and provide different paths for traffic on

different VLANs This improves the failover performance and

allows load balancing to occur through the network.

> IEEE 802.1d, 802.1w, 802.1Q-2005

– MSTP will interoperate with the other Spanning Tree Protocols

(STP, or RSTP.)

• VRRP(VirtualRouterRedundancyProtocol)

This standard protocol can be used to provide failover (or load

sharing) between switches, routers or hosts. Typically used in

large, complex network configurations.

– RFC 3768

• FailOverGroups(FOG)

This is a proprietary mechanism, allowing for very fast failover/

failback of switches or links in homogeneous networks. This is a

building block for High Availability configurations.

Layer3

The layer 3 operation of the OpenWare switch provides support

for routing of IP traffic between routing domains - this is provided

either statically or by the use of routing protocols in order to main-

tain dynamic routing information.

• Routing

OpenWare supports manual and protocol-controlled handling of

Layer 3 routing, in both IPv4 and IPv6.

– RFC 1519, 1812

• Routingprotocols

The routing protocols supported include RIP, OSPF and BGP

for IPv4 and RIPng, OSPF and BGP for IPv6.

– RFC 1058, 2453, 2328, 1997, 2439, 3107, 4241, 4456, 5056

• Tunnelling

Tunnelling is carrying one protocol inside another. Typically, this is

used to carry IPv6 traffic over an IPv4 network.

– RFC 2003, 3056, 3068, 3964, 4213

• DifferentiatedServices(DiffServ)

– Allows classification of packets flowing through the switch

and assign actions based on these – supports wide range of

classification, including IP or MAC address (source or destina-

tion), port, VLAN, Ethertype. Actions include, packet dropping,

switching, redirection, mirroring or packet counting. Using a

combination of these commands will provide a flexible method

of traffic management.

System

• IPAddressControl

The switch management entity can be configured with multiple

IPv4 and an IPv6 addresses.

• Systemcontrol

Comprehensive tools are provided for management of software

version, configurations, debugging, and logging.

• BuiltInTest(BIT)

OpenWare provides tools to run tests of the hardware, on startup

or on request or continuously, in the background. This provides a

high level of confidence in the switch operation.

• SystemInitialization

Making use of the flexibility of the underlying Linux system, Open-

Ware features can be scheduled to be started and configured

during the boot process.

Availability

OpenWare is available on a wide range of NETernity switches, with

many combinations of form factor, fiber or copper, slow to very fast

line speeds, different levels of ruggedness, thermals and packaging.

Please contact your sales representative to determine the appro-

priate switch you need for your project as the full suite

of OpenWare features may be limited on some models.
