Connect Router to the Network


Note
The images in this chapter are only for representation purposes, unless specified otherwise. The chassis' actual appearance and size may vary.

Connecting a Console to the Router

Before you create a network management connection for the router or connect the router to the network, you must create a local management connection through a console terminal and configure an IP address for the router. The router can be accessed using remote management protocols, such as SSH and Telnet. By default, SSH is included in the software image. But telnet is not part of the software image. You must manually install the telnet optional package to use it.

You also can use the console to perform the following functions, each of which can be performed through the management interface after you make that connection:

  • configure the router using the command-line interface (CLI)

  • monitor network statistics and errors

  • configure Simple Network Management Protocol (SNMP) agent parameters

  • initiate software download updates via console

You make this local management connection between the asynchronous serial port on a Route Processor card and a console device capable of asynchronous transmission. Typically, you can use a computer terminal as the console device. On the Route Processor cards, you use the console serial port.


Note
Before you can connect the console port to a computer terminal, make sure that the computer terminal supports VT100 terminal emulation. The terminal emulation software makes communication between the router and computer possible during setup and configuration.

Before you begin

  • The router must be fully installed in its rack. The router must be connected to a power source and grounded.

  • The necessary cabling for the console, management, and network connections must be available.

    • An RJ45 rollover cable and a DB9F/RJ45 adapter.

    • Network cabling should already be routed to the location of the installed router.

Procedure

Step 1

Configure the console device to match the following default port characteristics:

  • 115200 baud

  • 8 data bits

  • 1 stop bit

  • No parity

Step 2

Connect and RJ45 rollover cable to a terminal, PC terminal emulator, or terminal server.

The RJ45 rollover cable is not part of the accessory kit.

Step 3

Route the RJ45 rollover cable as appropriate and connect the cable to the console port on the chassis.

If the console or modem cannot use an RJ45 connection, use the DB9F/RJ45F PC terminal adapter. Alternatively, you can use an RJ45/DSUB F/F or RJ45/DSUB R/P adapter, but you must provide those adapters.

What to do next

You are ready to create the initial router configuration.

Connect the Management Interface

The Route Processor management port (MGMT ETH) provides out-of-band management, which lets you to use the command-line interface (CLI) to manage the router by its IP address. This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface.


Note
In a dual Route Processor router, you can ensure that the active Route Processor card is always connected to the network by connecting the management interface on both Route Processor cards to the network. That is, you can perform this task for each Route Processor card. When the Route Processor card is active, the router automatically has a management interface that is running and accessible from the network.

Caution
To prevent an IP address conflict, do not connect the MGMT 100/1000 Ethernet port until the initial configuration is complete.

Before you begin

You must have completed the initial router configuration.

Procedure

Step 1

Connect a modular, RJ-45, UTP cable to the MGMT ETH port on the Route Processor card.

Step 2

Route the cable through the central slot in the cable management system.

Step 3

Connect the other end of the cable to a 100/1000 Ethernet port on a network device.

What to do next

You are ready to connect the interface ports on each of the line cards to the network.

Transceivers, Connectors, and Cables

RJ-45 Connectors

The RJ-45 connector connects Category 3, Category 5, Category 5e, Category 6, or Category 6A foil twisted-pair or unshielded twisted-pair cable from the external network to the following module interface connectors:

  • Router chassis

    • CONSOLE port

    • MGMT ETH port


Caution

To comply with GR-1089 intrabuilding, lightning immunity requirements, you must use a foil twisted-pair (FTP) cable that is properly grounded at both ends.

The following figure shows the RJ-45 connector.

Install and Remove SFP28 and SFP+ Modules

Before you remove or install an SFP28 and SFP+ module, read the installation information in this section.


Warning

Statement 1051—Laser Radiation

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.


Caution
Protect the line card by inserting a clean SFP28/SFP+ module cage cover, which is shown in the figure below, into the optical module cage when there is no SFP28/SFP+ module installed.
Figure 2. SFP28/SFP+ Module Cage Cover

Caution
Protect the SFP28 or SFP+ modules by inserting clean dust covers into them after the cables are removed. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another module. Avoid getting dust and other contaminants into the optical ports of your SFP or SFP+ modules, because the optics do not work correctly when obstructed by dust.

Caution
We strongly recommended that you do not install or remove the SFP28 or SFP+ module with fiber-optic cables that are attached to it because of the potential of damaging the cable, the cable connector, or the optical interfaces in the module. Disconnect all cables before removing or installing an SFP28 or SFP+ module. Removing and inserting a module can shorten its useful life, so you should not remove and insert modules any more than is absolutely necessary.

Note
When installing an SFP28 or SFP+ module, you should hear a click as the triangular pin on the bottom of the module snaps into the hole in the receptacle. The click indicates that the module is correctly seated and secured in the receptacle. Verify that the modules are seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP28 or SFP+ module.

Bale Clasp SFP28 or SFP+ Module

The bale clasp SFP28 or SFP+ module has a clasp that you use to remove or install the module (see the figure below).

Figure 3. Bale Clasp SFP28 or SFP+ Module

Install a Bale Clasp SFP28 or SFP+ Module

To install this type of SFP28 or SFP+ module, follow these steps:

Procedure

Step 1

Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2

Close the bale clasp before inserting the SFP28 or SFP+ module.

Note

 

88-LC1-52Y8H-EM: For the top and middle rows of SFP28 or SFP+ ports, you must install transceivers right-side up (Cisco transceiver label facing down). For the bottom row of SFP28 or SFP+ ports, you must install transceivers upside down (Cisco transceiver label facing up, see illustration below).

Step 3

Line up the SFP28 or SFP+ module with the port and slide it into the port (see the figure below).

Note

 
To minimize the chance of damaging transceivers when installing them, slide them gently into their port. Never force transceivers all the way into the port. If the transceiver stops part way into the slot, it might be in the wrong orientation. Remove the transceiver before turning it over and reinstalling it. If positioned correctly, the transceiver slides all the way into the port and clicks when fully installed.
Figure 4. Installing a Bale Clasp SFP28 or SFP+ Module into a Port

Note

 
When installing an SFP28 or SFP+ module, you should hear a click as the triangular pin on the bottom of the SFP28 or SFP+ module snaps into the hole in the receptacle. This click indicates that the module is correctly seated and secured in the receptacle. Verify that the SFP28 or SFP+ modules are seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP28 or SFP+ module.

Step 3

Open the bale clasp on the SFP28/SFP+ module with your index finger, as shown in the figure below.

Note

 

If the bale clasp is obstructed and you cannot use your index finger to open it, use the Optical Transceiver Extraction Tool, a small flat-blade screwdriver, or other long, narrow instrument to open the bale clasp. See Using the Optical Transceiver Extraction Tool.

Step 4

Grasp the SFP module between your thumb and index finger and carefully remove it from the port, as shown in the figure below.

Note

 
This action must be performed during your first instance. After adjacent ports are populated, you may need to use the Optical Transceiver Extraction Tool.
Figure 5. Removing a Bale Clasp SFP or SFP+ Module

Step 5

Place the removed SFP module on an antistatic mat, or immediately place it in a static shielding bag if you plan to return it to the factory.

Step 6

Protect your line card by inserting a clean SFP module cage covers into the optical module cage when there is no SFP module installed.

Using the Optical Transceiver Extraction Tool

In a fully loaded 88-LC1-52Y8H-EM line card, the bale clasps of the SFP28 optics can be difficult to access. You can use the Optical Transceiver Extraction Tool to remove the network cable, open the bale clasp, and remove the transceiver.

  • Antistatic mat or antistatic foam to set the transceiver on.

  • Fiber-optic end-face cleaning tools and inspection equipment.

Installing the Transceiver Module


Warning

Statement 1079—Hot Surface

This icon is a hot surface warning. To avoid personal injury, do not touch without proper protection.


Caution
The transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling transceiver modules or coming into contact with system modules.

Caution

Protect the transceiver ports by inserting clean dust caps (8000-QSFP-DCAP) into any ports not in use and do not have optical modules plugged in. If optical modules are plugged in but not in use, the dust caps that were supplied with the optical modules, should be used to protect the TX and RX surfaces of the optical module.

Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another module.

The router ships with dust caps plugged in. We highly recommend you to keep the dust caps plugged in until you are ready to plug an optic.

The dust caps protect the ports from possible EMI interference and also avoid contamination due to dust collection. To meet the EMI interference requirements, you must use the metal dust caps when the ports are not in use by optical modules.

The following table provides the supported port details and operating temperature of the QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules when port side exhaust or port side intake fans and power supplies are used.

Caution

 
If the latch isn’t fully engaged, you might accidentally disconnect the transceiver module.
Figure 9. Seating the QSFP Transceiver Module

Attach the Optical Network Cable

Before you begin

Before you remove the dust plugs and make any optical connections, follow these guidelines:

  • Keep the protective dust plugs installed in the unplugged fiber-optic cable connectors and in the transceiver optical bores until you are ready to make a connection.

  • Inspect and clean the optical connector end faces just before you make any connections.

  • Grasp the optical connector only by the housing to plug or unplug a fiber-optic cable.


Note
The transceiver modules and fiber connectors are keyed to prevent incorrect insertion.

Note
The multiple-fiber push-on (MPO) connectors on the optical transceivers support network interface cables with either physical contact (PC) or ultra-physical contact (UPC) flat polished face types. The MPO connectors on the optical transceivers do not support network interface cables with an angle-polished contact (APC) face type.

Note

Inspect the MPO connector for the correct cable type, cleanliness, and any damage. For complete information on inspecting and cleaning fiber-optic connections, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document.

Procedure

Step 1

Remove the dust plugs from the optical network interface cable MPO connectors and from the transceiver module optical bores. Save the dust plugs for future use.

Step 2

Attach the network interface cable MPO connectors immediately to the transceiver module.

Grasp the pull-tab and gently pull to release the transceiver from the socket.

Step 4

Slide the transceiver out of the socket.

Step 5

Place the transceiver module into an antistatic bag.

Connect Interface Ports

You can connect optical interface ports on line cards with other devices for network connectivity.

Connect a Fiber-Optic Port to the Network

Depending on which line card model that you are using, you can use either QSFP+ or QSFP28 transceivers. Some transceivers work with fiber-optic cables that you attach to the transceivers and other transceivers work with pre-attached copper cables. You must install a transceiver in the port before installing the fiber-optic cable in the transceiver.


Caution

Removing and installing a transceiver can shorten its useful life. Do not remove and insert transceivers any more than is absolutely necessary. We recommend that you disconnect cables before installing or removing transceivers to prevent damage to the cable or transceiver.

Disconnect Optical Ports from the Network

When you need to remove fiber-optic transceivers, you must first remove the fiber-optic cables from the transceiver before you remove the transceiver from the port.

Create the Initial Router Configuration

Assign an IP address to the router management interface to connect the router to the network.

When you initially power up the router, it boots up and displays a series of configuration-related questions. You can use the default choices for each configuration except for the IP address, which you must provide.


Note

These routers are designed to boot up in less than 30 mins, provided the neighboring devices are in full-operational state.

When the system is powered on and the console port is connected to the terminal, the RP CPU messages are seen. You can toggle between BMC CPU messages and RP CPU messages by pressing the hot-key sequence Ctrl-O.

To configure IP address for Ethernet port on BMC and other additional information that is related to BMC, please see the System Setup Guide for Cisco 8000 Series Routers.

Before you begin

  • A console device must be connected with the router.

  • The router must be connected to a power source.

  • Determine the IP address and netmask that is needed for the Management interfaces: MgmtEth0/RP0/CPU0/0 and MgmtEth0/RP1/CPU0/0:

Procedure

Step 1

Power up the router.

The LEDs on each power supply light up (green) when the power supply units are sending power to the router, and the software asks you to specify a password to use with the router.

Step 2

When the system boots up for the first time, the system prompts you to create a new username and password. The following prompt appears: 



!!!!!!!!!!!!!!!!!!!! NO root-system username is configured. Need to configure root-system username. !!!!!!!!!!!!!!!!!!!!

--- Administrative User Dialog ---


Enter root-system username:
% Entry must not be null.

Enter root-system username: cisco
Enter secret:
Use the 'configure' command to modify this configuration.
User Access Verification

Username: cisco
Password:


RP/0/RP0/CPU0:ios#

Step 3

Enter a new password to use for this router.

The software checks the security strength of your password and rejects your password if the system does not consider it as a strong password. To increase the security strength of your password, make sure that it adheres to the following guidelines:

  • At least eight characters

  • Minimizes or avoids the use of consecutive characters (such as "abcd")

  • Minimizes or avoids repeating characters (such as "AAA")

  • Does not contain recognizable words in the dictionary

  • Does not contain proper names

  • Contains both uppercase and lowercase characters

  • Contains numbers and letters

Note

 
Cleartext passwords cannot include the dollar sign ($) special character.

Tip

 
If a password is trivial (such as a short, easy-to-decipher password), the software rejects that password. Passwords are case-sensitive.

When you enter a strong password, the software asks you to confirm the password.

Step 4

Reenter the password.

When you enter the same password, the software accepts the password.

Step 5

Enter the configuration mode.

Step 6

Enter the IP address for the management interface. If using dual RPs, enter the IP address on both management interfaces.

Step 7

Enter a network mask for the management interface.

Step 8

The software asks whether you want to edit the configuration.

  • no - select this option if you don't want to edit your configuration.
  • yes - select this option if you want to edit your configuration.

    Note

     

    We recommend that you configure the system location altitude for fan control. This configuration allows you to specify the chassis altitude, so the router can adjust the fan speed to compensate for lower cooling capability at higher altitudes. For more details, see the environment altitude command.

Verify Chassis Installation

After installing the chassis, use the following show commands to verify the installation and configuration in the EXEC mode. Any issue if detected, take corrective action before making further configurations.

Command

Description

show platform

Displays the state information of each card.

show redundancy

Displays the status of route processor redundancy.

show led

Displays LED information for the router, or for a specific LED location.

show hw-module fpd

Displays field-programmable device (FPD) compatibility for all modules or a specific module.

show alarms brief system active

Displays all existing alarms in the router.

show media

Displays the current state of the disk storage media.

show inventory

Displays information about the field replaceable units (FRUs), including product IDs, serial numbers, and version IDs.

show environment

Displays all the environment-related router information.

show environment temperature

Displays temperature readings for card temperature sensors. Each Route Processor, line card, and fabric cards have temperature sensors with two thresholds:

  • Minor temperature threshold – When a minor threshold is exceeded, minor alarm occurs and the following actions occur for all four sensors:

    • Displays system messages

    • Sends SNMP notifications (if configured)

    • Log environmental alarm event that can be reviewed by running the show alarm command.

  • Major temperature threshold – When a major threshold is exceeded, a major alarm occurs and the following actions occur:

    • For sensors 1, 3, and 4 (outlet and on board sensors), the following actions occur:

      • Displays system messages.

      • Sends SNMP notifications (if configured).

      • Logs environmental alarm event that can be reviewed by running the show alarm command.

    • For sensor 2 (intake sensor), the following actions occur:

      • If the threshold is exceeded in a switching card, only that card is shut down.

      • If the threshold exceeds an active Route Processor card with HA-standby or standby present, only that Route Processor card is shut down and the standby Route Processor card takes over.

      • If you do not have a standby Route Processor card in your router, you have up to 2 minutes to decrease the temperature. During this interval, the software monitors the temperature every 5 seconds and continuously sends system messages as configured.

Note

 

  • Cisco recommends that you install dual Route Processor cards.

  • For some card temperature sensors, the temperature thresholds for both minor and major might display 'NA'. This is an expected behaviour and indicates that there are no alarms for those corresponding thresholds.

show environment power

Displays the power usage information for the entire router.

show environment voltage

Displays the voltage for the entire router.

show environment current

Displays the current environment status.

show environment fan

Displays the status of the fan trays.

Caution
Please be careful while increasing the Altitude setting, as it leads to a rise in control sensor values and consequently the Chassis could shut down immediately if the control sensor crosses the critical threshold.

Router Verification Checks

Perform Pre-check Procedures on the Router

To ensure the fabric cards on the router are operational, you must perform the pre-check commands. These commands help identify any issues in the router setup.

Follow these steps to perform the pre-check procedures on a router to verify its status:

Procedure

Step 1

Execute the following set of commands on the router in XR EXEC mode or System Admin EXEC mode.

Example:

! 
term length 0 
! 
show version 
! 
show platform 
! 
show controller fabric fsdb-pla rack 0 
! 
show controller fabric link port s1 rx down 
! 
show controller fabric link port fia rx down 
! 
show controllers npu link-info rx 0 255 topo instance all location all | ex "EN/UP" | ex "NC              NC" 
! 
show controllers npu stats link all instance all location all | exc "0        0        0" 
! 
show controller fabric health 
! 
show inventory 
! 
show ip interface brief 
! 
show interface brief | i down | ex admin 
! 
show alarms brief system active  
!

Step 2

Verify that the Route Processors (RPs) and line cards (LCs) are in the IOS XR RUN and OPERATIONAL state.

Example:

Router:Cisco-8818#show platform

0/FC7             8818-FC0                 OPERATIONAL              NSHUT

Step 3

Capture the router output to a text file. Name the text file using the convention: hostname-pre-check-date.txt.

Example:

router1-pre-check-april-15-2024.txt

What to do next

Perform Fabric Link Status Checks

Perform Post-Check Procedures on the Router

After the router is powered on or after you perform any hardware replacements, perform these post-check commands:

Procedure

Step 1

Execute the first set of post-check commands.

Example:

! 
term length 0 
! 
show version 
! 
show platform 
! 
show controller fabric fsdb-pla rack 0 
! 
show controller fabric link port s1 rx down 
! 
show controller fabric link port fia rx down 
! 
show controllers npu link-info rx 0 255 topo instance all location all | ex "EN/UP" | ex "NC              NC" 
! 
show controllers npu stats link all instance all location all | exc "0        0        0" 
! 
show controller fabric health 
! 
show inventory 
! 
show ip int brief 
! 
show int brief | i down | ex admin 
! 
show alarms brief system active  
!

Step 2

Capture the results to a file, save it with a file naming ,convention, such as hostname-post-check1-date.txt.

Step 3

Power the router OFF and then ON by toggling the power button located on the front-side of the router.

Wait for the router to power up completely.

Step 4

Verify that all the line card LEDs are green and fan tray LEDs for each fan is green.

Step 5

Wait for 30 minutes, then execute the second set of post-check commands, capture the results to a file, and save it.

Step 6

Repeat step-1 through step-5 twice.

Step 7

Ensure that you save your results of the checks that you ran for three times for any future reference.

Set Fabric Bandwidth Threshold

Fabric bandwidth refers to the bandwidth requirements for communication and traffic flow between the line card and fabric card. The following table provides explanation of terminologies that are associated with fabric bandwidth.

Bandwidth threshold

A percentage value denoting a limit for bandwidth consumption.

Being a system level setting, the threshold applies to all the line card NPUs in the chassis.

It is a user configurable limit; default value is 5%.

Total required bandwidth

Total Fabric Bandwidth x Bandwidth Threshold.

If is a calculated value as a function of user-defined threshold.

Network interfaces on line card are active only when “Available bandwidth” is more than “Total required bandwidth”.

Lower required bandwidth

Total fabric bandwidth x (Bandwidth Threshold - 10%)

This computation is applicable only for bandwidth threshold values 20% or higher.

For bandwidth threshold values of below 20%, the “Lower required bandwidth” is equal to “Total required bandwidth”.

If is also a calculated value as a function of user-defined threshold and denotes a lower cut-off for disabling network interfaces on line card.

Disabling happens when “Available bandwidth” falls below the “Lower required bandwidth”.

The Bandwidth Threshold acts a check point to ensure substantial bandwidth availability to carry traffic to the fabric cards. To configure the bandwidth threshold, use the following commands: 

Router# configure 
Router (config)# hw-module profile bw-threshold <value>
Router (config)# commit

User can set the threshold value starting with 10 and in increments of 10.

For example, consider that the bandwidth threshold is set to 20%. If the available bandwidth goes below 10%, then the network interfaces of the line card are shut. If the available bandwidth goes above 20%, then the network interfaces of the line card are unshut. The following table provides threshold references.
