Juniper QFX3000-G QFabric, Руководство по развертыванию, Страница: 258 / 652

Use the following QFX3100 Director devices and EX4200 switches for a copper-based
QFX3000-G QFabric system control plane network:
•
QFX3100 Director devices with RJ-45 network modules installed. Each RJ-45 network
module provides four RJ-45 ports labeled
0
through
3
.
• EX4200-48T switches with an SFP+ uplink module installed.
Specific ports have been reserved on the Virtual Chassis to connect to each of the QFabric
system device types. Such design simplifies installation and facilitates timely deployment
of a QFabric system. It also permits the use of a standard Virtual Chassis configuration
(see
“Example: Configuring the Virtual Chassis for the QFX3000-G QFabric System
Control Plane” on page 283 ).
Before you begin to connect a QFX3100 Director device to the copper-based QFX3000-G
control plane network:
• Install your QFabric system hardware (Director group, Interconnect devices, and Node
devices). See
“Installing and Connecting a QFX3100 Director Device” on page 143 ,
“Installing and Connecting a QFX3008-I Interconnect Device” on page 155 , “Installing
and Connecting a QFX3600 or QFX3600-I Device” on page 193 , and “Installing and
Connecting a QFX3500 Device” on page 211 .
• Install your Virtual Chassis hardware (EX4200 switches). See Installing and Connecting
an EX4200 Switch .
•
Create two Virtual Chassis switches of four members each. See Configuring an EX4200,
EX4500, or EX4550 Virtual Chassis (CLI Procedure) .
• Interconnect the two Virtual Chassis switches using the 10-Gigabit Ethernet SFP+
uplink ports. See
“Interconnecting Two Virtual Chassis for Copper-Based QFX3000-G
QFabric System Control Plane Redundancy” on page 225 .
• Connect the two QFX3100 Director devices to create a Director group. See “Connecting
QFX3100 Director Devices in a Director Group” on page 228 .
•
Ensure that you have enough RJ-45 patch cables available, and ensure that the cables
meet the specifications described in
“Cable Specifications for Copper-Based Control
Plane Connections for the QFabric System” on page 126 .
To connect a QFX3100 Director device to the QFX3000-G QFabric control plane network
(see
Figure 64 on page 231 ):
1.
Connect both network modules on the first Director device (labeled DG0 in
Figure 64 on page 231 ) to the two Virtual Chassis (labeled VC0 and VC1 in
Figure 64 on page 231 ). You connect the first three ports (labeled 0 through 2 ) on the
first network module to the first Virtual Chassis ( VC0) . You connect the first three
ports on the second network module (also labeled 0 through 2 ) to the second Virtual
Chassis ( VC1 ). The ports used are the same on each Virtual Chassis.
