LM-4 Line Module

Module label ES2 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).
An ES2 4G LM with an ES2-S1 Service IOA (dedicated tunnel-server port) can receive traffic ranging from 3.5 Gbps (with 256 byte packets) to 3.8 Mbps (1024 to 1492 byte packets) for bidirectional L2TP LNS throughput. The throughput might be less with packets of smaller sizes.
A shared tunnel-server port on an ES2 4G LM can handle a maximum of 0.8 to 0.9 Gbps throughput for tunnel services, depending on the packet sizes. The throughput might be less with packets of smaller sizes.
