OmniSwitch 9000
Setting the crossover configuration to auto will configure the interface or interfaces to automatically
detect crossover settings. Setting crossover configuration to mdix will configure the interface or inter-
faces for MDIX (Media Dependent Interface with Crossover), which is the standard for hubs and
switches. Setting crossover to mdi will configure the interface or interfaces for MDI (Media
Dependent Interface), which is the standard for end stations. And setting the crossover configuration to
disable will disable crossover configuration on an interface or interfaces.
Verifying Ethernet Port Configurations To display information about Ethernet port configuration settings, use the show commands. These
commands can be quite useful in troubleshooting and resolving potential configuration issues or
problems on your switch. For more information about the resulting displays from these commands, see
the OmniSwitch CLI Reference Guide.

Performance
Principle of operation for Fabric Load Sharing
• Traffic intra-module to be processed & forwarded locally
• Traffic inter-module to be forwarded through the Virtual Switching Fabric
• Each Chassis Management Module (CMM) provides a 12Gbps Full Duplex (24Gbps
aggregated) connection between each NI module. For OS9600, each NI module leverages 2
connection to the CMM (versus 1 connection per CMM in OS9700/OS9800)
• OmniSwitch 9700 & 9800 full switching capacity is reached with dual CMMs
• OmniSwitch 9600 full switching capacity is reached with a single CMM
Principle of operation for Distributed Processing
• Each NI module provides a high performance CPU
o CMM’s CPU is responsible for management & overall coordination
o NI Module’s CPU is responsible for most operations
• Management bus is a dedicated Gigabit Ethernet Full Duplex bus
o Each NI module’s CPU supports a direct connection with each CMM’s CPU
Switching Scheme supported Locally within each NI Module or through the Switch Fabric on the CMM
Forwarding Capabilities Performances
• Centrally through the Switch Fabric on the CMM
OR
• Locally within the same NI Module
Each NI Module is capable of switching (forwarding) traffic centrally or locally:

Backplane Architecture & Backplane Capacity The OmniSwitch 9000 Series support a Passive Backplane.
 OS9600: capable of 960Gbps
 OS9700: capable of 960Gbps
Calculation Method for both OS9600 & OS9700 Backplane Arch. & Backplane Capacity:
Backplane capacity of 960Gbps
-Today, we use 4 lanes going in each direction, to each fabric, out of 8
-Each lane is running at 3.75GHz
- 3.75GHz x 4 = 15GHz (15Gbps)
- 8B/10B encoding => 12Gbps efficient
-If we are running ALL lanes at that speed then:
-Each lane, is going to each CMM, in each direction, on 8 slot @ 3.75Gbps
- 8 x 2 x 2 x 8 x 3.75 = 960Gbps
