Introduction

The following information provides an example for using Tcl commands on routers.

Prerequisites

The following information applies to Comware 9-based routers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the routers.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of Tcl commands.

Example: Configuring subinterfaces in bulk by using For loop Tcl commands

Network configuration

As shown in Figure 1, the router is connected to the host. Use For loop Tcl commands to create subinterfaces GigabitEthernet 0/0/1.1 to GigabitEthernet 0/0/1.4 for GigabitEthernet 0/0/1, and configure incremental IP addresses and VLAN termination settings with incremental VLAN IDs for the subinterfaces.

‌

Software versions used

This configuration example was created and verified on R9141P16 of the MSR2630E-X1 device.

Restrictions and guidelines

For Tcl commands, you cannot enter a question mark (?) to obtain online help or press Tab to complete an abbreviated command.

Successfully executed Tcl commands are not saved to command history buffers. You cannot use the upper arrow or lower arrow key to obtain executed commands.

During the execution of a loop body, any operation command will not take effect.

Procedures

# Enter Tcl configuration view from user view.

<Router> tclsh

# Enter system view.

<Router-tcl> system-view

# Start a For loop, and predefine the value of variable i as 1.

[Router-tcl] for {set i 1} {$i <= 4} {incr i 1} {

set j [expr $i+99]

# Create subinterfaces with incremental interface numbers for GigabitEthernet 0/0/1 and assign incremental IP addresses to the subinterfaces.

interface gigabitethernet 0/0/1.$i

ip add $i.1.1.1 24

# Configure VLAN termination settings with incremental VLAN IDs for the subinterfaces.

vlan-type dot1q vid $j}

[Router-tcl-GigabitEthernet0/0/1.4] quit

[Router-tcl] quit

<Router-tcl> tclquit

Verifying the configuration

# Display brief information about all interfaces to verify that the subinterface settings have been successfully configured.

<Router> display interface brief

Brief information on interface(s) under route mode:

Link: ADM - administratively down; Stby - standby

Protocol: (s) - spoofing

Interface            Link Protocol Main IP         Description

GE0/0/1.1            UP   UP       1.1.1.1

GE0/0/1.2            UP   UP       2.1.1.1

GE0/0/1.3            UP   UP       3.1.1.1

# Execute the display current-configuration interface command on each interface to verify that the VLAN termination settings have been successfully configured. This example uses GigabitEthernet 0/0/1.1.

<Router> display current-configuration interface gigabitethernet 0/0/1.1

Configuration files

For commands on the router:

for {set i 1} {$i <= 4} {incr i 1} {

set j [expr $i+99]

interface gigabitethernet 0/0/1.$i

ip address $i.1.1.1 24

vlan-type dot1q vid $j}

Example: Configuring subinterfaces in bulk by using While loop Tcl commands

Network configuration

As shown in Figure 2, the router is connected to the host. Use While loop Tcl commands to create subinterfaces GigabitEthernet 0/0/1.1 to GigabitEthernet 0/0/1.4 for GigabitEthernet 0/0/1, and configure incremental IP addresses and VLAN termination settings with incremental VLAN IDs for the subinterfaces.

Software versions used

This configuration example was created and verified on R9141P16 of the MSR2630E-X1 device.

Restrictions and guidelines

You must predefine the value of variables for While loop Tcl commands.

For Tcl commands, you cannot enter a question mark (?) to obtain online help or press Tab to complete an abbreviated command.

Successfully executed Tcl commands are not saved to command history buffers. You cannot use the upper arrow or lower arrow key to obtain executed commands.

During the execution of a loop body, any operation command will not take effect.

Procedures

# Enter Tcl configuration view from user view.

<Router> tclsh

# Enter system view.

<Router-tcl> system-view

# Start a While loop, and predefine the value of variable i as 1.

[Router-tcl] set i 1

1

[Router-tcl] while {$i <= 4} {

set j [expr $i+99]

# Create subinterfaces with incremental interface numbers for GigabitEthernet 0/0/1 and assign incremental IP addresses to the subinterfaces.

interface gigabitethernet 0/0/1.$i

ip address $i.1.1.1 24

# Configure VLAN termination settings with incremental VLAN IDs for the subinterfaces.

vlan-type dot1q vid $j

incr i}

[Router-tcl-GigabitEthernet0/0/1.4] quit

[Router-tcl] quit

<Router-tcl> tclquit
