Specifying a TACACS+ Server Host
To specify a TACACS+ server host and congure its communication parameters, use the following command.
• Enter the host name or IP address of the TACACS+ server host.
CONFIGURATION mode
tacacs-server host {hostname | ip-address} [port port-number] [timeout seconds] [key key]
Congure the optional communication parameters for the specic host:
• port port-number: the range is from 0 to 65535. Enter a TCP port number. The default is 49.
• timeout seconds: the range is from 0 to 1000. Default is 10 seconds.
• key key: enter a string for the key. The key can be up to 42 characters long. This key must match a key congured on the
TACACS+ server host. This parameter must be the last parameter you congure.
If you do not congure these optional parameters, the default global values are applied.
Example of Connecting with a TACACS+ Server Host
To specify multiple TACACS+ server hosts, congure the tacacs-server host command multiple times. If you congure multiple
TACACS+ server hosts, Dell EMC Networking OS attempts to connect with them in the order in which they were congured.
To view the TACACS+ conguration, use the show running-config tacacs+ command in EXEC Privilege mode.
To delete a TACACS+ server host, use the no tacacs-server host {hostname | ip-address} command.

Enabling SCP and SSH
Secure shell (SSH) is a protocol for secure remote login and other secure network services over an insecure network. Dell EMC Networking
OS is compatible with SSH versions 1.5 and 2, in both the client and server modes. SSH sessions are encrypted and use authentication.
SSH is enabled by default.
For details about the command syntax, refer to the Security chapter in the Dell EMC Networking OS Command Line Interface Reference
Guide
.
Dell EMC Networking OS SCP, which is a remote le copy program that works with SSH.
NOTE
: The Windows-based WinSCP client software is not supported for secure copying between a PC and a Dell EMC
Networking OS-based system. Unix-based SCP client software is supported.
To use the SSH client, use the following command.
• Open an SSH connection and specify the hostname, username, port number,encryption cipher,HMAC algorithm and version of the SSH
client.
EXEC Privilege mode
ssh {hostname} [-l username | -p port-number | -v {1 | 2}| -c encryption cipher | -m HMAC
algorithm
hostname is the IP address or host name of the remote device. Enter an IPv4 or IPv6 address in dotted decimal format (A.B.C.D).
