请教 三年前购买的msr5600可以远程管理吗？

msr56系列的设备不支持web页面的，ssh可以配置。参考案例如下：

<SW2>system-view

System View: return to User View with Ctrl+Z.

[SW2]ssh server enable             //开启ssh服务

[SW2]public-key local create rsa                //生成RSA密钥

The local key pair already exists.

Confirm to replace it? [Y/N]:y

The range of public key modulus is (512 ~ 2048).

If the key modulus is greater than 512, it will take a few minutes.

Press CTRL+C to abort.

Input the modulus length [default = 1024]:

Generating Keys...

Create the key pair successfully.

[SW2]public-key local create dsa                //生成DSA密钥

The range of public key modulus is (512 ~ 2048).

If the key modulus is greater than 512, it will take a few minutes.

Press CTRL+C to abort.

Input the modulus length [default = 1024]:

Generating Keys...

Create the key pair successfully.

[SW2]local-user admin                         //新建用户

New local user added.

[SW2-luser-manage-admin]password simple admin        //配置密码

[SW2-luser-manage-admin]service-type ssh             //服务类型ssh

[SW2-luser-manage-admin]authorization-attribute user-role level-15   //用户等级15

[SW2-luser-manage-admin]quit

[SW2]ssh user admin service-type stelnet authentication-type password      //配置ssh用户admin的服务类型为stelnet，认证方式为password（此步骤可不配置）

[SW2]user-interface vty 0 4                //允许五个同时登陆

[SW2-line-vty0-4]authentication-mode scheme                 //选用账号密码验证
