在 BES-53248 集群交换机上启用 SSH

贡献者

如果要使用以太网交换机运行状况监控器(CSHM)和日志收集功能、则必须生成SSH密钥、然后在集群交换机上启用SSH。

步骤

  1. 验证SSH是否已禁用：

    show ip ssh

    显示示例 
    (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. 生成 SSH 密钥：

    crypto key generate

    显示示例 
    (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!
    警告 请确保在修改密钥之前禁用SSH、否则交换机上会报告警告。

  3. 加密SSH密钥(仅限* FIPS模式*)：

    注意 在FIPS模式下、为了安全起见、需要使用密码短语对密钥进行加密。如果没有加密密钥、应用程序将无法启动。可使用以下命令创建和加密密钥：
    显示示例 
    (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. 重新启动交换机：

    re负载

  5. 验证是否已启用 SSH ：

    show ip ssh

    显示示例 
    (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
