手順

 

This article provides the steps necessary to restrict management access to using HTTPS and SSH.

 
Caution: This process requires use of the Command Line Interface (CLI). This process can be utilized through a serial or telnet session. However these steps must be followed in order to prevent unintentionally blocking access to remote management.

 

This procedure assumes:

  • The switch is already configured with an IP address and is reachable within the network.
  • There is an account created with Privilege Level 15.  To verify this, use the command: console#show users accounts.
Note: After completing these steps, you can expect to receive errors about certificate authenticity. This is due to the certificates and keys being self-generated. This is not an error.

 

Caution: Before disabling either telnet or HTTP access, verify SSH or HTTPS access.
Note: If SSH or HTTPS is enabled and the disabling of telnet and HTTP is desired, skip to step 3 to disable telnet and step 5 to disable HTTP.
  1. Connect to the switch via CLI
  2. To enable SSH, enter the following commands:
    1. console> enable
    2. console# config
    3. console(config)# crypto key generate rsa
    4. console(config)# crypto key generate dsa
    5. console(config)# ip ssh server
  3. To disable telnet, enter:  console(config)#no ip telnet server
  4. To enable HTTPS, enter the following commands"
    1. console(config)# crypto certificate 1 generate key
    2. console(config)# ip https certificate 1
    3. console(config)# ip http secure-server
Note: This system is capable of the generation and storage of 2 certificates. To generate the second key, replace the number 1 with 2. To activate the second key, use (config)#ip https certificate 2.
  1. To disable HTTP, enter:  console(config)# no ip http server
  2. After verifying connectivity via SSH or HTTPS, save the configuration by entering:  console#copy running-config startup-config
