Se si utilizzano le funzioni di Cluster Switch Health Monitor (CSHM) e di raccolta dei log, è necessario generare le chiavi SSH e attivare SSH sugli switch del cluster.

Fasi

  1. Verificare che SSH sia disattivato:

    show ip ssh

    Mostra esempio 
    (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. Generare le chiavi SSH:

    crypto key generate

    Mostra esempio 
    (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!

  3. Riavviare lo switch:

    reload

  4. Verificare che SSH sia attivato:

    show ip ssh

    Mostra esempio 
    (switch)# show ip ssh

SSH Configuration

Administrative Mode: .......................... Enabled
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: ........... Enabled
SCP server Administrative Mode: ............... Enabled
