Managing High-Density Ethernet

The overall data rate for the GE-HDE line module is 2 Gbps; therefore, the I/O module
becomes highly oversubscribed because of the wire rate of the line module. The data
rate of the GE-8 I/O module is limited with larger frames, and the packet rate is
limited with smaller frames.
Currently, flow control using MAC pause frames is disabled on the GE-8 I/O module.
The I/O module does not transmit or receive pause frames.
For more information about high-density Ethernet, see "High-Density Ethernet" on
page 196.

OC3-2 GE APS I/O Module

ERX7xx models, ERX14xx models, and the ERX310 router all support the OC3-2 GE
APS I/O module.
The OC3-2 GE APS I/O module pairs with the OC3/STM1 GE/FE line module to provide
Gigabit Ethernet operation through one line interface and OC3 STM1 ATM operation
through two line interfaces.
The OC3-2 GE APS I/O module uses a range of SFPs to support different optical modes
and cabling distances, and accepts up to three LC-style fiber-optic or copper SFPs.
You can configure only port 2 for Gigabit Ethernet interfaces; port 0 and port 1 are
reserved for OC3/STM1 ATM interfaces.
For more information about configuring OC3/STM-1 ATM interfaces on this I/O
module, see "OC3/STM1 GE/FE Line Module" on page 79.
NOTE: The OC3-2 GE APS I/O module does not support APS in the current release.

ES2-S1 GE-4 IOA

The E120 and E320 routers support the ES2-S1 GE-4 IOA. Other E Series routers do
not support the ES2-S1 GE-4 IOA.
The ES2-S1 GE-4 IOA pairs with the ES2 4G line module (LM). For more information
about the ES2 4G LM, see "ES2 4G Line Module" on page 80.
