JUNOSe 11.1.x Physical Layer Configuration Guide
The interface stack for OC3/STM1 ATM interfaces on the OC3-2 GE APS I/O module
is the same as for OCx/STMx/DS3-ATM interfaces. (See Figure 5 on page 78.)
For more information about configuring a Gigabit Ethernet interface on this I/O
module, see "OC3-2 GE APS I/O Module" on page 182.
NOTE: The OC3-2 GE APS I/O module does not support APS in the current release.
ES2 4G Line Module
The E120 and E320 routers support the ES2 4G LM. Other E Series routers do not
support the ES2 4G LM. For more information about modules on the E120 and E320
routers, see the E120 and E320 Module Guide.
The ES2 4G LM supports IOAs that support single-mode operation (intermediate
reach or long haul). IOAs are available in a halfheight size, which enables you to
configure them in either of the two IOA bays that are available for each slot. For
more information about installing IOAs, see the E120 and E320 Hardware Guide.
In the current release, the ES2 4G LM pairs with IOAs to provide OCx/STMx ATM,
OCx/STMx POS, Gigabit Ethernet, 10-Gigabit Ethernet, and tunnelservice interfaces.
NOTE: For more information about configuring a Gigabit Ethernet interface or
10-Gigabit Ethernet interface, see "Configuring Ethernet Interfaces" on page 175.
For more information about configuring a tunnel-service interface by using the Tunnel
Server IOA, see "Managing Tunnel-Service and IPSec-Service Interfaces" on page 215.
E120 Router Configuration
The 120 Gbps switch fabric of the E120 router allocates 10 Gbps of overall bandwidth
to each line module slot. The line interface on the ES2 4G LM when installed in a
120 Gbps fabric configuration is 3.9 Gbps; you can achieve this rate with random
packet sizes from 64–1518 bytes or a mixture of packet sizes that represent Internet
mix traffic (IMIX).
E320 Router Configuration
The 100 Gbps switch fabric of the E320 router 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 (slots 2 and 4). The line interface on the ES2 4G LM when installed in a
100 Gbps fabric configuration is 3.4 Gbps; you can achieve this rate with packet sizes
greater than 128 bytes.
The 320 Gbps switch fabric of the E320 router 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
80
