To upload the configuration to the switch:

Syntax:

scp <local filename> <username>@<switch IP address>:putcfg

Example:

>># scp ad4.cfg scpadmin@205.178.15.157:putcfg

To apply and save the configuration

The apply and save commands are still needed after the last command, or use the following commands:

>># scp ad4.cfg scpadmin@205.178.15.157:putcfg_apply

>># scp ad4.cfg scpadmin@205.178.15.157:putcfg_apply_save

„The diff command is automatically executed at the end of putcfg to notify the remote client of the difference between the new and the current configurations.

„putcfg_apply runs the apply command after the putcfg is done.

„putcfg_apply_save saves the new configuration to the flash after putcfg_apply is done.

„The putcfg_apply and putcfg_apply_save commands are provided because extra apply and save commands are usually required after a putcfg; however, an SCP session is not in an interactive mode at all.

SSH and SCP Encryption of Management Messages

The following encryption and authentication methods are supported for SSH and SCP:

Server Host Authentication:

Client RSA authenticates the switch at the beginning of

 

every connection

Key Exchange:

RSA

Encryption:

3DES-CBC, DES

User Authentication:

Local password authentication, RADIUS, SecurID

 

(via RADIUS, TACACS+, for SSH only—does not apply

 

to SCP)
