How to: Enabling Telnet control of an ICX Switch

Introduction

By default, ICX Switches have telnet disabled as a security measure.
If your switch has been configured so that it cannot be accessed by others, you may wish to enable telnet so that commands can be sent from a control system. For example you may wish to send commands to turn the PoE power on an off to reboot a PoE device.
 

This guide assumes that you access the switch using the default VLAN 1.To enable telnet use the following procedure:

1. Login to the switch.
2. Switch to Privileged exec mode, and then Global config mode:

enable
configure terminal
(note, you can abbreviate enable to ena or en, and configure terminal to conf t or con t)

3. Change the ports as required and paste the following code:

! --- Enable Telnet connections on VLAN1 ---
telnet server enable vlan 1
telnet server
! –-- Check status of Telnet server ---
sh telnet

4. Once the telnet server has been enabled, PoE ports can be toggled using the following commands (replace 1/1/2 with the port you wish to reboot):

int eth 1/1/2
! Disable PoE on the port
no inline power
! Enable PoE on the port
inline power
