Bring-up the Cisco NCS 6008 Router

After installing the hardware, boot the Cisco NCS 6008 Series Router . Connect to the XR VM console port and power on the router. The routersystem 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 an external bootable USB drive.

After booting is complete, create the root username and password, and then use it to log on to the XR VM console and get the router prompt. From the XR VM console, access the System Admin VM console to configure system administration settings.

For more information about completing the hardware installation, see Cisco Network Convergence System 6000 Series Routers Hardware Installation Guide.

The topics covered in this chapter are:

Connect to the XR VM Console Port and Power the Router

Use the XR VM console port on the Route Processor (RP) to connect to a new router . If required, subsequent connections can be established through the management port, after it is configured.

There are the three console ports on the RP. Console port 2 is for the XR VM.

Figure 1. XR VM console port of the RP


Procedure

Step 1

Connect a terminal to the XR VM console port of the RP.

Step 2

Start the terminal emulation program on your workstation.

The console settings are 115200 bps, 8 data bits, 1 stop bit and no parity.

Step 3

Power on the router.

Press the power switch up to turn on the power shelves. As the router boots up, you will see boot process details on the console screen of the terminal emulation program.

Step 4

Press Enter.

When the system prompts you to enter the root-system username, it indicates that the boot process is complete. If the prompt does not appear, wait for a while to give the router more time to complete the initial boot procedure, then press Enter.

Important 

If the boot process fails, it may be because the pre-installed image on the router is corrupt. In this case, the router can be booted using an external bootable USB drive. For details see, Create Bootable USB Drive Using Shell Script and Boot the Router Using USB.

What to do next

Specify the root username and password.

Setup Root User Credentials and Login to XR VM Console

When the router boots for the first time, the system prompts the user to configure root credentials (username and password). These credentials are configured as the root user on the XR VM (root-lr), the System Admin VM (root-system), and as disaster-recovery credentials. In addition to the XR VM console, the System Admin VM console and the XR VM management port can be accessed using these credentials.

Before you begin

The boot process must be complete. For details on how to initiate the boot process, see Connect to the XR VM Console Port and Power the Router System topic.

SUMMARY STEPS

  1. Enter root-system username: username
  2. Enter secret: password
  3. Enter secret again: password
  4. Username: username
  5. Password: password
  6. (Optional) show run username

DETAILED STEPS

Step 1

Enter root-system username: username

Example:

Enter root-system username: root

Enter the username of the root user. The character limit is 1023. In this example, the name of the root user is "root".

Important 

The specified username is mapped to the "root-lr" group on the XR VM. It is also mapped as the "root-system" user on the System Admin VM.

When starting the router for the first time, or after a re-image, the router does not have any user configuration. In such cases, the router prompts you to specify the "root-system username". However, if the router has been configured previously, the router prompts you to enter the "username", as described in Step 4.

Step 2

Enter secret: password

Example:

Enter secret:

Enter the password for the root user. The character limit is 253. The password you type is not displayed on the CLI for security reasons.

The root username and password must be safeguarded as it has the superuser privileges. It is used to access the complete router configuration.

Step 3

Enter secret again: password

Example:

Enter secret again:

Re-enter the password for the root user. The password is not accepted if it does not match the password entered in the previous step. The password you type is not displayed on the CLI for security reasons.

Step 4

Username: username

Example:

Username: root

Enter the root-system username to login to the XR VM console.

Step 5

Password: password

Example:

Password:

Enter the password of the root user. The correct password displays the XR VM router prompt. 

RP/0/RP0/CPU0:router#

You are now logged into the XR VM console.

Step 6

(Optional) show run username

Example:

RP/0/RP0/CPU0:router#show run username

Displays user details. 


username root
 group root-lr
 group cisco-support
 secret 5 $1$NBg7$fHs1inKPZVvzqxMv775UE/
!

What to do next

  • Configure routing functions from the XR VM.

  • Configure system administration settings from the System Admin prompt. The System Admin prompt is displayed on accessing the System Admin VM console. For details on how to get the System Admin prompt, see Access the System Admin VM Console topic.

Configure the XR VM Management Port

To use the XR VM Management port for system management and remote communication, you must configure an IP address and a subnet mask for the management ethernet interface. To communicate with devices on other networks (such as remote management stations or TFTP servers), you need to configure a default (static) route for the router .

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 management network.

SUMMARY STEPS

  1. configure
  2. interface MgmtEth rack/slot/CPU0/port
  3. ipv4 address ipv4-address subnet-mask
  4. ipv4 address ipv4 virtual address subnet-mask
  5. no shutdown
  6. exit
  7. router static address-family ipv4 unicast 0.0.0.0/0 default-gateway
  8. Use the commit or end command.

DETAILED STEPS

Step 1

configure

Example:


RP/0/RP0/CPU0:router# configure

Enters XR Config mode.

Step 2

interface MgmtEth rack/slot/CPU0/port

Example:

RP/0/RP0/CPU0:router(config)#interface mgmtEth 0/RP0/CPU0/0

Enters interface configuration mode for the management interface of the primary RP.

Step 3

ipv4 address ipv4-address subnet-mask

Example:

RP/0/RP0/CPU0:router(config-if)#ipv4 address 10.1.1.1 255.0.0.0

Assigns an IP address and a subnet mask to the interface.

Step 4

ipv4 address ipv4 virtual address subnet-mask

Example:

RP/0/RP0/CPU0:router(config-if)#ipv4 address 1.70.31.160 255.255.0.0

Assigns a virtual IP address and a subnet mask to the interface.

Step 5

no shutdown

Example:

RP/0/RP0/CPU0:router(config-if)#no shutdown

Places the interface in an "up" state.

Step 6

exit

Example:

RP/0/RP0/CPU0:router(config-if)#exit

Exits the Management interface configuration mode.

Step 7

router static address-family ipv4 unicast 0.0.0.0/0 default-gateway

Example:

RP/0/RP0/CPU0:router(config)#router static address-family ipv4 unicast 0.0.0.0/0 12.25.0.1

Specifies the IP address of the default-gateway to configure a static route; this is to be used for communications with devices on other networks.

Step 8

Use the commit or end command.

commit —Saves the configuration changes and remains within the configuration session.

end —Prompts user to take one of these actions:

  • Yes — Saves configuration changes and exits the configuration session.

  • No —Exits the configuration session without committing the configuration changes.

  • Cancel —Remains in the configuration session, without committing the configuration changes.

What to do next

Connect to the management port to the ethernet network. See Connecting to the XR VM Management Port.

Connecting to the XR VM Management Port

The XR VM management port supports 10/100G optical small form-factor pluggable (SFP) units to provide high speed network connectivity. The SFPs that can be connected to the XR VM management port are:

1000BASE-LX/LH SFP
1000BASE-T SFP

Before you begin

Configure the management port. See Configure the XR VM Management Port.

Procedure

Step 1

Connect the SFP module to the XR VM management port.

The XR VM management port on the RP is shown in this figure.

Note 

RJ-45 port is disabled by default. Do not use the RJ-45 port. Use only the 1G copper SFP port as showm in the image below.
Figure 2. XR VM console port of the RP


Step 2

Depending on the SFP module type, connect either a optical fiber or an ethernet cable to the SFP.

What to do next

With a terminal emulation program, establish a SSH or telnet connection to the management interface port using its IP address. For details on configuring the IP address of the management port, see Configure the XR VM Management Port.

Before establishing a telnet session, use the telnet ipv4|ipv6 server max-servers command in the XR Config mode, to set number of allowable telnet sessions to the router.

Note

Telnet supports a maximum of 100 (including both IPv4 and IPv6) sessions.

For a SSH connection, the ncs6k-k9sec package must be installed on the router. For details about package installation, see the Install Packages section.

Provision Breakout Interfaces

The NCS 6000 line cards have multi-slice architecture. On a 10X100G line card, each slice has two 100 GE ports that can be configured to operate at 100 GE or 10X10 GE. Breakout cables are connected to the 10X10GE interfaces. The 100G ports are mapped to each slice as:

Shut Down Unused Linecard Slices

The NCS 6000 linecards, namely, NCS 6000 10x100G Multi-Service CPAK, NCS 6000 10x100G Multi-Service CXP, and NCS 6000 60x10GE PAT, have multi-slice architecture. The 10X100G line cards has 5 slices, whereas the 60X10G line cards has 4 slices. Each slice can be individually shut down:

  • To save power- Shutting down a slice will power down the slice. This will reduce the power consumption of that line card. The mode of operating line cards with one or more slices shut is called the green mode.


    Note

    Shutting down a slice will also delete the Virtual Output Queue (VOQ) and this drops the ingress-traffic.

  • For troubleshooting - If a slice is malfunctioning, shutting it down isolates the slice from the system, thus reducing its impact on the router. Also, troubleshooting can be done within the domain of the slice.

SUMMARY STEPS

  1. configure
  2. hw-module location rack/slot/CPU slice slice_number shutdown
  3. Use the commit or end command.

DETAILED STEPS

Step 1

configure

Example:


RP/0/RP0/CPU0:router# configure

Enters XR Config mode.

Step 2

hw-module location rack/slot/CPU slice slice_number shutdown

Example:

RP/0/RP0/CPU0:router(config)#hw-module location 0/1/CPU0 slice 3 shutdown

Shuts down the specified slice. The interfaces belonging to the slice that is shut down are deleted from the system and are not visible in the output of the show interfaces brief command.

Step 3

Use the commit or end command.

commit —Saves the configuration changes and remains within the configuration session.

end —Prompts user to take one of these actions:

  • Yes — Saves configuration changes and exits the configuration session.

  • No —Exits the configuration session without committing the configuration changes.

  • Cancel —Remains in the configuration session, without committing the configuration changes.

What to do next

To make a shutdown slice operational, use the no hw-module location rack/slot/CPU slice slice_number shutdown command.

Verify the slice shut down using show platform in XR VM or show platform slices in System Admin VM.

Perform Clock Synchronization with NTP Server

There are independent system clocks for the XR VM and the System Admin VM. To ensure that these clocks do not deviate from true time, they need to be synchronized with the clock of a NTP server. In this task you will configure a NTP server for the XR VM. After the XR VM clock is synchronized, the System Admin VM clock will automatically synchronize with the XR VM clock.

Before you begin

Configure and connect to the XR VM management port.
