Administrator Guide

ssh
Open an SSH connection specifying the hostname, username, encryption cipher, HMAC algorithm, port number, and version of
the SSH client.
C9000 Series
Syntax
NOTE: Some of the parameters in this command require licensing to access. For more information,
contact your Dell Networking representative.
ssh[vrf vrf-name] {hostname | ipv4 address | ipv6 address} [-c encryption
cipher | -l username | -m HMAC algorithm | -p port-number | -v {1 | 2}]
Parameters
vrf vrf-name (OPTIONAL) Enter the keyword vrf aand then the name of the VRF to specify the
VRF used with the SSH session.
NOTE: The VRF configured using this command has a higher precedence than
the VRF configured using the ip ssh vrf vrf-name command. If you do
not configure a VRF using this command, then the SSH client uses the
configured VRF (if any). If there is a mismatch between VRFs that are
configured using the ip ssh source-interface command and the ssh
vrf vrf-name command, then an error is reported.
hostname (OPTIONAL) Enter the IP address or the host name of the remote device.
vrf instance (OPTIONAL) E-Series Only: Enter the keyword vrf then the VRF Instance name to
open an SSH connection to that instance.
ipv4 address (OPTIONAL) Enter the IP address in dotted decimal format A.B.C.D.
ipv6-address
prefix-length
(OPTIONAL) Enter the IPv6 address in the x:x:x:x::x format then the prefix length
in the /x format. The range is from /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
-c encryption
cipher
Enable the “FIPS mode enable", this mode will support only v2 client.
"no fips mode enable"(disable) will support v1 & v2 client. This comment is
applicable for both ciphers & HMAC algorithms:
● 3des-cbc
● aes128-cbc
● aes192-cbc
● aes256-cbc
● aes128-ctr
● aes192-ctr
● aes256-ctr
-l username (OPTIONAL) Enter the keyword -l then the user name used in this SSH session.
The default is the user name of the user associated with the terminal.
-m HMAC
algorithm
Enter one of the following HMAC algorithms to use. (For v2 clients only):
"no fips mode enable"(disable) will support v1 & v2 client.
● hmac-sha1: Force ssh to use hmac-sha1 HMAC algorithm.
● hmac-sha1-96: Force ssh to use hmac-sha1-96 HMAC algorithm.
● hmac-md5: Force ssh to use hmac-md5 HMAC algorithm.
● hmac-md5-96: Force ssh to use hmac-md5-96 HMAC algorithm.
● hmac-sha2-256 : Force ssh to use hmac-sha2-256 HMAC algorithm.
-p port-number (OPTIONAL) Enter the keyword -p then the port number. The range is from 1 to
65535. The default is 22.
