Features and Capabilities

Algo Boost technology allows the Cisco Nexus 3548 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

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

The Cisco Nexus 3548 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)

Specifications at a Glance

  • 48 fixed 1/10 Gbps small form factor pluggable plus (SFP+) ports
  • Line-rate layer 2 and layer 3 throughput of up to 480 Gbps
  • Compact 1RU form factor
  • Dual, redundant, color-coded power supplies
