Features and Capabilities

Algo Boost technology allows the Cisco Nexus 3548/3548-X to achieve exceptionally low latencies of 250 nanoseconds (ns) or less for all workloads. That includes unicast and multicast, and layer 2 and 3 switching, regardless of the features applied.

Benefits include:

  • Warp mode to further reduce latency to 190 ns for small-to-midsize layer 2 and 3 deployments
  • Warp SPAN to help enable stock market data delivery to trading servers in as little as 50 ns
  • Active Buffer Monitoring to help you take advantage of market volatility and handle micro bursts
  • Technology that supports Network Address Translation (NAT) for trade execution on any venue, without a latency penalty
  • Embedded Remote SPAN with nanosecond timestamps to help you monitor your traffic with superior precision
  • Multicast NAT and latency monitoring leading to simplified co-location integration and enhanced traffic visibility and troubleshooting (only 3548-X model).
  • Next generation 3548-X offers lower power consumption further lowering operational cost

Comprehensive Feature Set with Cisco Nexus Operating System (NX-OS)

The Cisco Nexus 3548/3548-X is powered by the data-center-class, Cisco NX-OS. Features include:

  • Full-featured unicast protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing Information Protocol (RIP)
  • Multicast protocols, including Protocol Independent Multicast-Sparse Mode (PIM-SM), PIM-Source-Specific Multicast (PIM-SSM), and Multicast Source Discovery Protocol (MSDP)
  • Full support for access control lists (including port, VLAN, and routed) and quality of service (queueing and marking)
  • Full support for troubleshooting tools such as Switched Port Analyzer (SPAN) and Ethanalyzer
  • Switch management by Cisco Prime Data Center Network Manager (DCNM)
