Maintaining the PTX5000 Host Subsystem

Maintaining the PTX5000 Host Subsystem

Purpose

For optimum PTX5000 performance, verify the condition of the host subsystem. Each host subsystem comprises a Routing Engine and an adjacent Control Board functioning together.

Action

On a regular basis:

  • Check the host subsystem LEDs OK and Fail on the craft interface for (HOST0 and HOST1. For more information about the LEDs on the craft interface, see PTX5000 Craft Interface LEDs.

    During normal operations:

    • The green host subsystem OK LED on the craft interface is lit.

    • The red host subsystem FAIL LED on the craft interface is not lit.

Understanding the Effect of Taking the PTX5000 Host Subsystem Offline

Taking a Nonredundant Host Subsystem Offline

Taking a nonredundant host subsystem offline shuts down the PTX5000.

Taking a Backup Host Subsystem Offline

Taking a backup host subsystem offline does not interrupt the functioning of the PTX5000. The backup host subsystem is hot-removable and hot-insertable.

Taking a Primary Host Subsystem Offline

Removal or failure of the primary Routing Engine affects forwarding and routing based on the high availability configuration.

Note:

For information about configuring high availability features such as graceful Routing Engine switchover (GRES) and nonstop active routing (NSR), see the High Availability User Guide.

Both Routing Engines should be running the same Junos OS release.

If the backup Routing Engine's configuration differs from the former primary's configuration, router performance might change. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to each Routing Engine.

To configure Routing Engine-specific parameters and still use the same configuration on both Routing Engines, include the appropriate configuration statements under the re0 and re1 statements at the [edit groups] hierarchy level and use the apply-groups statement. For instructions, see the Junos OS Administration Library.

When a primary host subsystem is taken offline or during a primary role switch, the backup host subsystem becomes the primary, and the backup Routing Engine assumes Routing Engine functions. The primary host subsystem is hot-pluggable. During the switchover to the backup Routing Engine:

  • Dual Routing Engines without any high availability features enabled—Traffic is interrupted while the Packet Forwarding Engine is reinitialized. Packet forwarding halts while the standby Routing Engine becomes the primary and the Packet Forwarding Engine components reset and connect to the new primary Routing Engine. All kernel and forwarding processes are restarted. When the switchover to the new primary Routing Engine is complete, routing convergence takes place and traffic is resumed.

  • GRES is supported on Junos OS Release 12.1X48 and later.

    GRES is enabled—Graceful Routing Engine switchover preserves interface and kernel information. Traffic is not interrupted. The backup Routing Engine immediately assumes Routing Engine functions and there is no interruption to packet forwarding. However, graceful Routing Engine switchover does not preserve the control plane. Neighboring routers detect that the PTX5000 has restarted and react to the event in a manner prescribed by individual routing protocol specifications. To preserve routing without interruption during a switchover, graceful Routing Engine switchover must be combined with nonstop active routing.

  • Nonstop active routing is supported on Junos OS Release 12.1X48R3 and later.

    Nonstop active routing is enabled (graceful Routing Engine switchover must be configured for nonstop active routing to be enabled)—Nonstop active routing supports Routing Engine switchover without alerting peer nodes that a change has occurred. Nonstop active routing uses the same infrastructure as graceful Routing Engine switchover to preserve interface and kernel information. However, nonstop active routing also preserves routing information and protocol sessions by running the routing protocol process (rpd) on both Routing Engines. In addition, nonstop active routing preserves TCP connections maintained in the kernel.

  • Graceful restart is configured—Graceful restart provides extensions to routing protocols so that neighboring helper routers restore routing information to a restarting router. These extensions signal neighboring routers about the graceful restart and prevent the neighbors from reacting to the router restart and from propagating the change in state to the network during the graceful restart period. Neighbors provide the routing information that enables the restarting router to stop and restart routing protocols without causing network reconvergence. Neighbors are required to support graceful restart. The routing protocol process (rpd) restarts. A graceful restart interval is required. For certain protocols, a significant change in the network can cause graceful restart to stop.

Maintaining the PTX5000 Routing Engines

Purpose

For optimum performance, verify the condition of the Routing Engines.

Action

On a regular basis:

  • Check the host subsystem LEDs on the craft interface. During normal operations, the OK LED is lit green, and the FAIL LED is not lit. See PTX5000 Craft Interface LEDs.

  • Check the LEDs on the Routing Engine. During normal operation, the ONLINE LED on each Routing Engine is lit green, indicating that the Routing Engine is functional. See PTX5000 Routing Engine LEDs.

  • Look at the LCD display on the craft interface to view information about the status of the Routing Engines.

  • Issue the show chassis routing-engine command to verify that the Routing Engines are operating properly.

Replacing a PTX5000 RE-DUO-C2600 Routing Engine

Taking the PTX5000 Host Subsystem Offline

Before you replace a Routing Engine, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Be aware of the effect of taking a host subsystem offline on traffic, forwarding, and routing. See Understanding the Effect of Taking the PTX5000 Host Subsystem Offline.

To take a host subsystem offline:

  1. Determine whether the Routing Engine to be replaced is currently functioning as the primary or as the backup, using one of the following methods:
    1. Check the HOST 0 and HOST 1 LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the primary.

    2. Check the MASTER LED on the Control Board. If the blue MASTER LED is lit, the host subsystem is functioning as the primary.

    3. Issue the show chassis routing-engine command. The primary Routing Engine is designated Master in the Current state field.

  2. If the Routing Engine to be replaced is currently functioning as the primary, switch it to backup using the CLI command:
  3. Halt the host subsystem.
    Note:

    The request system halt command halts the Routing Engine on the control plane from which it was issued. The command shuts down the Routing Engine cleanly, so its state information is preserved. The SIBs might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued. To reboot a Routing Engine that has been halted, you must connect through the console.

  4. On the console or other management device connected to the other Routing Engine, enter CLI operational mode and issue the following command.

    n is 0 or 1 for the slot number of the host subsystem being taken offline.

  5. Verify that the Control Board is offline:

Removing a PTX5000 Routing Engine

The PTX5000 can have one or two Routing Engines. They are located in a slot inside the Control Board below the SIBs in the rear of the chassis. Each Routing Engine can weigh up to 2.8 lb (1.3 kg).

To remove a Routing Engine (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Take the host subsystem offline.
