High cost of conventional matrix switches make scaling very expensive

Filtering and forwarding are statically configured, not event driven

Limitation on interconnection of Matrix Switches to build a scalable topology

Challenges with The Conventional Approach

Cisco Nexus Data BrokerPacket Filtering Features

Packet tagging features at ingress

Support IEEE 802.1Q encapsulation for source-port tagging Perform VLAN and MPLS tag stripping Time-stamp packet at ingress based on PTP (IEEE 1588) Truncate packet at ingress at set number of bytes (minimum 64 bytes)

Packet filtering capabilities

Filter based on Layer 1 through Layer 4 information Perform Layer 7 filtering for HTTP traffic based on HTTP methods Enable bidirectional packet matching Support dropping of all matching traffic

Traffic load balancing

Load-balance traffic to multiple monitoring tools Enable symmetric hashing with:

Layer 3 (IP address) information Layer 3 plus Layer 4 (IP address plus protocol plus port) information

I want to see web traffic on my packet-analysis tool …

Cisco Nexus Data BrokerPacket Forwarding Features

Multipoint-to-multipoint (MP2MP) traffic

Specify one or more input ports (TAP or Cisco® SPAN) Can replicate and forward traffic to N number of

monitoring tools Monitoring tools can be connected to different switches

Any-to-multipoint (A2MP) traffic

Input port in monitor topology is not known Can replicate and forward traffic to N number of

monitoring tools Monitoring tools can be connected to different switches Programmed flows follow loop-free forwarding path

Complex topologies require(and Cisco Nexus® Data Broker

provides):

Automation of flow programming

Capability to automatically adapt to topology changes
