Product Description

Series Overview:

The Cisco 7600 Series ES+ line cards are a multiple-fabric, fixed-port Ethernet line card for the Cisco 7600 series routers that are capable of 40 gbps full-duplex traffic forwarding using a fixed port interface design.

Product Overview:

The Cisco 7600 Series ES+ line cards have the following features:

  • Line rate feature processing performance with 64 byte packets for four ports of 10 GE or forty ports of GE (59.52Mpps). Note that the line card throughput is limited by the system switch fabric. The packet processor and internal sections of the line card are full line rate throughput capable for 40GbE.
  • Large output buffers provide up to 200 mS of round-trip-time buffer (100 mS in each direction) per 10GE port or 10xGE ports to prevent transient output overloads from causing spurious packet loss.
  • Up to 32K queues (per 10GE port or 10xGE ports) per direction for input or output queuing and scheduling.
  • Programmable ingress and egress feature processing capability through the Trident.
  • 40+ Mpps Layer 3 or Layer 4 forwarding, 125Mpps Layer 2 forwarding.
  • Dual fabric attachment providing an aggregate bandwidth of 40Gb/s, full duplex (each fabric channel provides 20Gb/s, full duplex).
  • 512-MB boot disk
