Ative o SSH nos switches de cluster BES-53248

PDFs

Se você estiver usando os recursos do Monitor de integridade do comutador Ethernet (CSHM) e da coleção de logs, será necessário gerar as chaves SSH e, em seguida, ativar o SSH nos switches do cluster.

Passos

  1. Verifique se o SSH está desativado:

    show ip ssh

    Mostrar exemplo 
    (switch)# show ip ssh

SSH Configuration

Administrative Mode: .......................... Disabled
SSH Port: ..................................... 22
Protocol Level: ............................... Version 2
SSH Sessions Currently Active: ................ 0
Max SSH Sessions Allowed: ..................... 5
SSH Timeout (mins): ........................... 5
Keys Present: ................................. DSA(1024) RSA(1024) ECDSA(521)
Key Generation In Progress: ................... None
SSH Public Key Authentication Mode: ........... Disabled
SCP server Administrative Mode: ............... Disabled

  2. Gerar as chaves SSH:

    crypto key generate

    Mostrar exemplo 
    (switch)# config

(switch) (Config)# crypto key generate rsa

Do you want to overwrite the existing RSA keys? (y/n): y


(switch) (Config)# crypto key generate dsa

Do you want to overwrite the existing DSA keys? (y/n): y


(switch) (Config)# crypto key generate ecdsa 521

Do you want to overwrite the existing ECDSA keys? (y/n): y

(switch) (Config)# aaa authorization commands "noCmdAuthList" none
(switch) (Config)# exit
(switch)# ip ssh server enable
(switch)# ip scp server enable
(switch)# ip ssh pubkey-auth
(switch)# write mem

This operation may take a few minutes.
Management interfaces will not be available during this time.
Are you sure you want to save? (y/n) y

Config file 'startup-config' created successfully.

Configuration Saved!
    Aviso Certifique-se de que o SSH está desativado antes de modificar as chaves, caso contrário, um aviso é relatado no switch.

  3. Encripte as chaves SSH (apenas para o modo FIPS):

    Cuidado No modo FIPS, as chaves devem ser criptografadas com uma senha para segurança. Na ausência de uma chave criptografada, o aplicativo não inicia. As chaves são criadas e criptografadas usando os seguintes comandos:
    Mostrar exemplo 
    (switch) configure
(switch) (Config)# crypto key encrypt write rsa passphrase <passphase>

The key will be encrypted and saved on NVRAM.
This will result in saving all existing configuration also.
Do you want to continue? (y/n): y

Config file 'startup-config' created successfully.

(switch) (Config)# crypto key encrypt write dsa passphrase <passphase>

The key will be encrypted and saved on NVRAM.
This will result in saving all existing configuration also.
Do you want to continue? (y/n): y

Config file 'startup-config' created successfully.

(switch)(Config)# crypto key encrypt write ecdsa passphrase <passphase>

The key will be encrypted and saved on NVRAM.
This will result in saving all existing configuration also.
Do you want to continue? (y/n): y

Config file 'startup-config' created successfully.

(switch) (Config)# end
(switch)# write memory

This operation may take a few minutes.
Management interfaces will not be available during this time.
Are you sure you want to save? (y/n) y

Config file 'startup-config' created successfully.

Configuration Saved!

  4. Reinicie o switch:

    reload

  5. Verifique se o SSH está ativado:

    show ip ssh

    Mostrar exemplo 
    (switch)# show ip ssh

SSH Configuration

Administrative Mode: .......................... Enabled
