Functions

Table 7-371  Functions of the EH1D2L08QX2E
Function Description

Basic function

  • Provides eight 40GE Ethernet optical ports for data access and switching.

  • Allows a 40GE port to split into four 10GE ports.

Distributed forwarding

Performs concurrent data forwarding using a distributed data plane.

Hot swapping

Supported

Application

A 40GE network can be established by installing 40GE cards on aggregation switches and core switches, as shown in Figure 7-168.

Figure 7-168  40GE cards deployed on a campus network

A 40GE network with 40GE cards deployed has the following advantages:

  • Provides higher bandwidth.
  • Is compatible with 10GE networks because a 40GE interface can be split into four 10GE interfaces. This feature enables customers to seamlessly upgrade their 10GE networks to 40GE networks.
  • Has a higher efficiency and lower packet loss ratio than a 40GE network established by bundling four 10GE lines for load balancing.

The 40GE cards are used on networks that need to provide high bandwidth, for example, video surveillance bearer networks and high-definition (HD) video conference bearer networks. The following uses an HD video conference bearer network as an example to describe application of 40GE cards.

Transmission of HD video and voice flows consumes high bandwidth on a network, especially on the aggregation layer and core layer. The bandwidth of aggregation and core devices usually becomes a bottleneck on an HD video conference bearer network. As shown in Figure 7-168, 40GE cards are deployed on the aggregation layer and core layer to transmit HD video and voice flows faster, more efficiently, with fewer packets lost. This deployment ensures sufficient bandwidth for the HD video conference bearer network and delivers high quality HD images and voice.

NOTE:

When multiple QSFP+ cables are connected to an EH1D2L08QX2E card, divide all the cables on the card into two bundles. Route the two bundles in two layers through the cable management frame to ensure that the bend radius of the cables is in the allowed range.

40GBASE-X port

Table 7-373 lists attributes of a 40GBASE-X port.
