CHAPTER 2

Get to Know Cisco 8000 Series Routers

Cisco 8000 series routers converge the service provider routing and massively scalable data centers (MSDC)

switching portfolio. The routers run on XR 7 OS. The XR 7 OS provides significant architectural enhancements

to Cisco IOS XR in these areas:

•Modularity: Decoupled hardware and software; modularized software with the flexibility to consume

software packages based on requirement.

•Programmability: Model-driven APIs at all layers.

•Manageability: Simplified software management and installation based on Linux tools.

•Baseboard Management Controller, on page 3

Baseboard Management Controller

Cisco 8000 series routers support Baseboard Management Controller (BMC) in the Route Processor (RP).

BMC is a specialized service processor that communicates with the system through an independent ethernet

connection. BMC operates in two modes:

•Lights-on mode: In this mode, RP CPU, which is independent and in parallel to BMC, is booted up.

This mode provices access to remote console, ethernet management port, supervisory and environmetal

device.

•Lights-out mode: In this mode, RP CPU is not booted up. This mode provides access to ethernet

management port, troubleshooting and recovery, boot parameters for BIOS, supervisory and environmental

device.

For information about how to configure the IP address for BMC, see Configure IP Address for Ethernet Port

on BMC, on page 10.

This article helps you set up your Cisco 8000 series router. You will bring the router up, run a system health

check, create user profiles, and assign user privileges.

CHAPTER 3

Bring-up the Cisco 8000 Series Router

Connect to the console port on a Route Processor (RP) of the router, and power ON the router. By default,

this console port connects to the XR console. If necessary, after configuration, establish subsequent connections

through the management port.

The following table shows the console settings:

Table 1: Console Settings

Data bitsStop bitsParityBaud rate (in bps)

82None115200

The baud rate is set by default and cannot be changed.

The router can be accessed using remote management protocols, such as SSH, Telnet, SCP and FTP. SSH is

included in the software image by default, but telnet is not part of the software image. You must manually

install the telnet optional package to use it.

After booting is complete, you must create a username and password. This credential is used to log on to the

XR console, and get to the router prompt.

The router completes the boot process using the pre-installed operating system (OS) image. If no image is

available within the router, the router can be booted using iPXE boot or an external bootable USB drive.

Boot the Cisco 8000 Series Router Using iPXE

Boot the router using iPXE if the router fails to boot when powered ON. An alternate method is to Boot the

Cisco 8000 Series Router Using USB Drive.

iPXE is a pre-boot execution environment in the network card of the management interfaces. It works at the

system firmware (UEFI) level of the router. iPXE boot re-images the system, boots the router in case of a

boot failure, or in the absence of a valid bootable partition. iPXE downloads the ISO image, installs the image,

and finally bootstraps inside the new installation.

iPXE acts as a bootloader. It provides the flexibility to choose the image that the system boots. The image is

based on the Platform Identifier (PID), the serial number, or the management mac-address. iPXE is defined

in the DHCP server configuration file.

You need a server running HTTPS, HTTP, or TFTP. Bring-up the PXE prompt using the following steps:

When you bring up a router using the PXE boot mode, existing configurations are removed. To recover smart

licensing configurations like Permanent License Reservation (PLR), enable these configurations after the

router comes up.

System Setup Guide for Cisco 8000 Series Routers, IOS XR Release 7.3.x

6

Bring-up the Cisco 8000 Series Router

Boot the Cisco 8000 Series Router Using iPXE

Router# configure

Router(config)# license smart reservation

Router(config)# commit

Step 1 Power ON the router.

Step 2 Press Esc or Del keys continuously (quick and repeated press and release) to pause the boot process, and get the RP to

the BIOS menu.

Step 3 Select Built-in iPXE option.

Step 4 When PXE boot starts reaching for a PXE server, press Ctrl+B keys to break into the PXE prompt.

Step 5 Add the following configuration for the router. This is required for the router to connect with the external server to

download, and install the image. You can use HTTP, HTTPS or TFTP server.

Example:

iPXE> ifopen net0 #Open the interface connecting outside world

iPXE> set net0/ip 10.0.0.2 #Configure the ip address of your router

iPXE> set net0/gateway 10.0.0.1 #configure the GW

iPXE> set net0/netmask 255.0.0.0 #Configure the Netmask

iPXE> ping 10.0.0.1 #Check you can reach GW

iPXE> ping 192.0.2.0 #check you can reach to your server running tftp or http or

https

iPXE> boot http://192.0.2.0/<directory-path>8000-x64.iso #Copy the image on the http/https/tftp

server in any path and then point to download the image from there.

To rectify errors while typing the command, use Ctrl+H keys to delete a character.

Note

If a PXE server is configured to run a DHCP server, it assigns an IP address to the Ethernet Management interface of the

router. This provides a channel to download the image that is required to re-image a router in case of a boot failure.

Router#reload bootmedia network location all

Proceed with reload? [confirm]

iPXE> boot http://<server-address>/<directory-path-to-iso>/8000-x64.iso # The protocol could be

http/https or tftp based on PXE server config

http://<server-address>/<directory-path-to-iso>/8000-x64.iso... 50%

Boot the Cisco 8000 Series Router Using USB Drive

Boot the router using USB drive if the router fails to boot when powered ON. An alternate method is to Boot

the Cisco 8000 Series Router Using iPXE.

Before you begin

Have access to a USB drive with a storage capacity that is between 8GB (min) and 32 GB (max). USB 2.0

and USB 3.0 are supported.

Step 1 Copy the bootable file to a USB disk.

A bootable USB drive is created by copying a compressed boot file into a USB drive. The USB drive becomes bootable

after the contents of the compressed file are extracted.

System Setup Guide for Cisco 8000 Series Routers, IOS XR Release 7.3.x

Bring-up the Cisco 8000 Series Router

Boot the Cisco 8000 Series Router Using USB Drive

If you are unable to boot from a USB drive, remove and insert the drive again. If the drive is inserted correctly,

and still fails to read from the USB drive, check the contents of the USB on another system.

Note

This task can be completed using Windows, Linux, or MAC operating systems available on your local machine.

a) Connect the USB drive to your local machine and format it with FAT32 or MS-DOS file system using the Windows

Operating System or Apple MAC Disk Utility. To check if the disk is formatted as FAT32, right click on the USB

disk, and view the properties.

b) Copy the compressed boot file in .zip format from the image file to the USB drive. This .zip file can be downloaded

from the Cisco Software Download center.

c) Verify that the copy operation is successful. To verify, compare the file size at source and destination. Additionally,

verify the MD5 checksum value.

d) Extract the contents of the compressed boot file by unzipping it inside the USB drive. This converts the USB drive

to a bootable drive.

Extract the contents of the zipped file ("EFI" and "boot" directories) directly into the root folder of the USB

drive. If the unzipping application places the extracted files in a new folder, move the "EFI" and "boot"

directories to the root folder of the USB drive.

Note

e) Eject the USB drive from your local machine.

Step 2 Use the bootable USB drive to boot the router or upgrade its image using one of the following methods:

Insert the USB drive in the USB port of the ACTIVE RP.

Note

•Boot menu

a. Insert the USB drive, and connect to the console.

b. Power ON the router.

c. Press Esc or Del to pause the boot process, and get the RP to the BIOS menu.

d. Select the USB option from the boot menu.

UEFI: Built-in iPXE

URFI: Built-in Shell

URFI: Built-in Grub

UEFI: USB Flash Memory1.00, Partition 1

The RP boots the image from the USB drive, and installs the image onto the hard disk. The router boots from

the hard disk after installation.

•XR CLI

Use this method if you can access the XR prompt.

The RP has two USB ports. If there is only one USB drive with a bootable image, insert it into any of the

two USB ports. If there are two USB drives but only one has a bootable image, the choice of the USB port

is negligent. However, if two USB drives are inserted simultaneously and both have a bootable image, the

image in the lower USB port takes precedence.

Note

a. Insert the USB device in the active RP.

b. Access the XR prompt and run the command:

The RP boots the image from the USB and installs the image onto the hard disk. The router boots from the hard

disk after installation.

Configure the Management Port on the Cisco 8000 Series Router

To use the management port for system management and remote communication, you must configure an IP

address and a subnet mask for the Management Ethernet interface.

We recommend that you use a Virtual Private Network (VPN) routing and the forwarding (VRF) on the

Management Ethernet interface.

Note

Before you begin

• Consult your network administrator or system planner to procure IP addresses and a subnet mask for the

management interface.

• Physical port Ethernet 0 on RP is the management port. Ensure that the port is connected to the

management network.

Step 1 Configure a VRF.

Example:

Router#conf t

Router(config)#vrf <vrf-name>

Router(config-vrf)#exit

Step 2 Enter interface configuration mode for the management interface of the primary RP.

Example:

Router(config)#interface mgmtEth 0/RP0/CPU0/0

Step 3 Configure the Management Ethernet interface under the VRF.

Example:

Router(config-if)#vrf <vrf-name>

Step 4 Assign an IP address and a subnet mask to the interface.

System Setup Guide for Cisco 8000 Series Routers, IOS XR Release 7.3.x

9

Bring-up the Cisco 8000 Series Router

Configure the Management Port on the Cisco 8000 Series Router

Example:

Router(config-if)#ipv4 address 10.1.1.1/8 255.255.0.0

Step 5 Assign a virtual IP address and a subnet mask to the interface. The virtual address is primarily used for out-of-band

management over the Management Ethernet interface.

Example:

Router(config-if)#ipv4 virtual address vrf <vrf-name> 10.10.10.1/24

Step 6 Place the interface in UP state.

Example:

Router(config-if)#no shutdown

Step 7 Exit the management interface configuration mode.

Example:

Router(config-if)#exit

Step 8 Specify the IP address of the default-gateway to configure a static route; this is used for communications with devices

on other networks.

Example:

Router(config)#router static vrf <vrf-name> address-family ipv4 unicast 0.0.0.0/0 10.10.10.1/24

Step 9 Commit the configuration.

Example:

Router(config)#commit

Step 10 Connect to the management port to the ethernet network. With a terminal emulation program, establish a SSH or telnet

connection to the management interface port using its IP address.

Configure IP Address for Ethernet Port on BMC

Baseboard Management Controller (BMC) is a component in the Route Processor (RP) that monitors bootup

status and the health of hardware components using sensors. It communicates with the system through an

independent connection. The independent connection is through a dedicated ethernet connection between the

host and BMC. BMC also has an ethernet interface for connections external to the router. You can establish

communication with this interface using REST or SSH services.

You can configure static IP or use DHCP for automatic IP assignment by DHCP server. For static IP assignment,

connect to BMC console.

The Management Ethernet port is shared between XR and BMC. However, the IP address of BMC must be

different from the XR interface, but in the same range.

Note

To establish communication over ethernet (external to BMC and XR), configure static IP address on ethernet

port 0 (eth0). IPv4 and IPv6 static IP addresses can be assigned. Modify the template in

/etc/systemd/network/00-bmc-eth0.network with appropriate static IP address and gateway

System Setup Guide for Cisco 8000 Series Routers, IOS XR Release 7.3.x

Bring-up the Cisco 8000 Series Router

Configure IP Address for Ethernet Port on BMC

information. To modify the file, you must have root user privileges. Once modified, the system assigns the

same IP address on eth0 ethernet device across BMC reloads.

Step 1 Switch to BMC console from the XR console.

Example:

Router#[ctrl] o

Phosphor OpenBMC (Phosphor OpenBMC Project Reference Distro) 0.1.0 ttyS4

Step 2 Set up a root username and password for BMC.

Example:

login: root

You are required to change your password immediately (administrator enforced)

New password:

Retype new password:

Step 3 Check that the BMC configuration file is available. If the file is unavailabke, then create one in the following template.

Example:

root:~# cat /etc/systemd/network/00-bmc-eth0.network

[Match]

Name=eth0

[Network]

DHCP=ipv4

LinkLocalAddressing=fallback

[DHCP]

ClientIdentifier=mac

# For static ip addresses replace above two sections with the following section

#[Network]

#Address=a.b.c.d/xy

#Gateway=a.b.p.q

Step 4 Modify the file using Vi text editor. Configure BMC with the network address and the gateway information.

Example:

vi /etc/systemd/network/00-bmc-eth0.network

Step 5 Save the file.

Step 6 View the content of the modified file.

Example:

root:~# cat /etc/systemd/network/00-bmc-eth0.network

[Match]

Name=eth0

#[Network]

#DHCP=ipv4

#LinkLocalAddressing=fallback

#[DHCP]

#ClientIdentifier=mac

# For static ip addresses replace above two sections with the following section

[Network]

Address=192.168.0.2/24

Gateway=192.168.0.1

Step 7 Reboot BMC using reboot Linux command for the configuration to take effect.

Configure IP Address for Ethernet Port on BMC

You can use Intelligent Platform Management Interface (IPMI) and REST interfaces to manage out-of-band

BMC information.

For information about structure and usage examples for the REST interface, see OpenBMC REST API and

OpenBMC REST cheat sheet.

By default, IPMI capability is disabled. For IPMI to function, you must enable netipmi using the following

command:

netipmi_config.sh -s 1

For example, the following ipmi command displays sensors using BMC IP address:

Note

Synchronize Router Clock with NTP Server

Synchronize the XR clock with that of an NTP server to avoid a deviation from true time. BMC is also

synchronised with XR through a local NTP connection.

NTP uses the concept of a stratum to describe how many NTP hops away a machine is from an authoritative

time source. A stratum 1 time server typically has an authoritative time source (such as a radio or atomic

clock, or a GPS time source) directly attached to the server. A stratum 2 time server receives its time through

NTP from a stratum 1 time server, and so on.

The Cisco implementation of NTP does not support stratum 1 service.

Note

Bring-up the Cisco 8000 Series Router

Synchronize Router Clock with NTP Server

Before you begin

Configure and connect to the management port.

Step 1 Enter the XR configuration mode.

Example:

Router#configure

Step 2 Synchronize the console clock with the specified sever.

Example:

Router(config)#ntp server <NTP-source-IP-address>

The NTP source IP address can either be an IPv4 or an IPv6 address. For example:

IPv4:

Router(config)#ntp server 192.0.2.0

IPv6:

Router(config)#ntp server 2001:DB8::1

The NTP server can also be reachable through a VRF if the Management Ethernet interface is in a VRF.

Note

Step 3 Commit the configuration.

Example:

Router(config-ntp)#commit

Step 4 Verify that the clock is synchronised with the NTP server.

Example:

Router#show ntp status

Clock is synchronized, stratum 3, reference is 192.0.2.0

nominal freq is 1000000000.0000 Hz, actual freq is 1000000000.0000 Hz, precision is 2**24

Reload a Node on Cisco 8000 Series Router

Reload a specified location or the complete hardware module. This command when used with all option

reloads the chassis. Reloading of a hardware module reloads all the locations on that card. Use the force option

to perform an ungraceful reload of the specified location or hardware module. When force option is used

along with the all location, the chassis undergoes an ungraceful reload. Use the noprompt option to avoid

the prompt to confirm the operation.

The following example shows ungraceful reloading of a specific location:

Router#reload location 0/1/CPU0 force

Proceed with reload? [confirm]

Step 2 Verify that the node is reloaded.

Example:

Router#show platform

In Exec mode, 0/XXX/CPU0 denotes a specific location, and 0/XX donotes the complete hardware module. For

example, 0/1/CPU0 denotes the CPU0 location on module 1, 0/1 denotes the complete hardware module.

Note

Shut Down a Node on Cisco 8000 Series Router

Shut down the complete hardware module for a specified location. To power on the hardware module for the

specified location, use the no form of the command.

Step 1 Shut down the node using one of the two options:

•Shut down from the configuration mode:

a. Enter the XR configuration mode.

Example:

Router#config

b. Shut down the complete hardware module for a specified location. Route processors (RPs) cannot be shut down

using this command.

Example:

Router(config)#hw-module shutdown location 0/1/CPU0

c. Commit the configuration.

Under the configuration mode, the location CPU0 denotes the complete hardware module.

Note

•Shut down from the Exec mode:

a. Shut down a specified location or the complete hardware module in Exec mode. Shutting down of a hardware

module shuts down all the locations on that card. Use force option to perform an ungraceful shut down of the

specified location or hardware module. Use the noprompt option to avoid the prompt asking for user confirmation.

Example: The following example shows the shut down of a specific location:

Router#shutdown location 0/1/CPU0

Proceed with shutdown? [confirm]

Example: The following example shows the shut down of the complete hardware module:

Router#shutdown location 0/1

Proceed with shutdown? [confirm]

Example: The following example shows the ungraceful shut down of a specific location:

Router#shutdown location 0/1/CPU0 force

Mon Sep 28 19:07:25.019 UTC

Proceed with shutdown? [confirm]

In Exec mode, 0/XXX/CPU0 denotes a specific location, and 0/XX donotes the complete hardware

module. For example, 0/1/CPU0 denotes the CPU0 location on module 1, 0/1 denotes the complete

hardware module.

Note

b. Confirm to proceed with the shut down operation.

Step 2 Verify that the node is shutdown.

Example:

Router#show platform
