LM-4 Line Module

Module labelES2 4G LM
Number of ports
  • Not applicable
Software release
  • First supported: 7.0.1
Description
  • 176 W maximum
  • Acts as frame forwarding engines for the physical interfaces
  • Responsible for processing data traffic
  • Pairs with IOAs to process data from different types of network connections
Type
  • FFA ASIC
Capability
  • Supports a line rate of 128–byte packets on IOAs
  • The 100–Gbps switch fabric allocates 3.4 Gbps of overall bandwidth to each regular line module slot and 10 Gbps of overall bandwidth to each of the turbo slots (slot 2 and slot 4).
  • The 320–Gbps switch fabric allocates 10 Gbps of overall bandwidth to each line module slot. The line interface on the ES2 4G LM when installed in a 320 Gbps fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes in the range 64–1518 bytes or a mixture of packet sizes that represent Internet mix traffic (IMIX).
