在BS-53248叢集交換器上啟用SSH

如果您使用乙太網路交換器健全狀況監視器（ CSHM ）和記錄收集功能、則必須產生 SSH 金鑰、然後在叢集交換器上啟用 SSH 。

步驟

  1. 確認 SSH 已停用：

    show ip ssh

    顯示範例 
    (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. 產生SSH金鑰：

    crypto key generate

    顯示範例 
    (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 修改金鑰之前、請務必先停用 SSH 、否則交換器上會報告警告。

  3. 加密 SSH 金鑰（僅適用於 * FIPS 模式 * ）：

    警告 在 FIPS 模式中、金鑰必須使用密碼來加密、以確保安全。如果沒有加密金鑰、應用程式就無法啟動。使用下列命令建立和加密金鑰：
    顯示範例 
    (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. 重新啟動交換器：

    "重裝"

  5. 確認SSH已啟用：

    show ip ssh

    顯示範例 
    (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
