Example: Configuring a JCS1200 Platform and Multiple T Series Routers

In this configuration example, the JCS1200 platform is connected to multiple T Series routers. The configuration is described in the following sections:

Requirements

This configuration example requires the following hardware and software components:

  • JUNOS Release 9.2 or later
  • JCS1200 platform with Routing Engines in slots 1 through 12
  • T320 router with FPCs in slots 0 through 7
  • T640 router with FPCs in slots 0 through 7
  • T1600 router with FPCs in slots 0 through 7

Overview

This example configures the JCS1200 platform and three connected T Series routers. For this example, you need to configure a Root System Domain (RSD) for each connected T Series router. Within each RSD, create Protected System Domains (PSDs) and assign Flexible PIC Controllers (FPCs) and Routing Engines to each PSD.

Configuration

First, configure the Routing Engines on the JCS1200 platform using the management module CLI. Then, configure each T Series router using the JUNOS CLI.

JCS1200 Platform Configuration

Step-by-Step Procedure

To configure the parameters required for the Routing Engines in the JCS chassis:

  1. Log in to the JCS management module.
  2. Refer to the data presented in Table 1 for Routing Engine assignments.

Verification

Verifying Configured PSDs

Purpose

Verify that the PSDs configured under each RSD are online.

Action

On each RSD issue the show chassis psd command:

RSD1


user@rsd1> show chassis psd
PSD  Description         State               Uptime
 1   psd for customer1   Online              1 hour, 12 minutes, 15 seconds
 2   psd for customer2   Online              1 hour, 12 minutes, 15 seconds

RSD2


user@rsd2> show chassis psd
PSD  Description         State               Uptime
 3   psd for customer3   Online              1 hour, 12 minutes, 15 seconds
 4   psd for customer4   Online              1 hour, 12 minutes, 15 seconds

RSD3


user@rsd3> show chassis psd
PSD  Description         State               Uptime
 5   psd for customer5   Online              1 hour, 12 minutes, 15 seconds
 6   psd for customer6   Online              1 hour, 12 minutes, 15 seconds

Meaning

RSD1 owns PSD1 and PSD2. RSD2 owns PSD3 and PSD4. RSD3 owns PSD4 and PSD5. All PSDs are online.

Verifying PSD Ownership of FPCs

Purpose

Verify that each PSD is assigned the correct FPCs on the T Series router.

Action

For each PSD, issue the show chassis fpc command. For example:


user@psd1> show chassis fpc
rsd-re0:
--------------------------------------------------------------------------
                     Temp  CPU Utilization (%)   Memory    Utilization (%)

  1  Online            52      4          0       2048        3         24
  2  Online            34      3          1       256        12         50

Meaning

In this example, PSD1 owns the FPCs in slots 0, 1, 2, and 3 on the T Series router.

Verifying PSD Ownership of Routing Engines

Purpose

Verify that each PSD owns the correct Routing Engines on the JCS chassis.

Action

On each PSD, issue the show chassis routing-engine command. For example:


user@psd2> show chassis routing-engine
