ssh
Open an SSH connection specifying the hostname, username, encryption cipher, HMAC algorithm, port number, and version of the SSH
client.
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: Force ssh to use 3des-cbc encryption cipher.
• aes128-cbc : Force ssh to use aes128-cbc encryption cipher
• aes192-cbc : Force ssh to use aes192-cbc encryption cipher
• aes256-cbc : Force ssh to use aes256-cbc encryption cipher
• aes128-ctr : Force ssh to use aes128-ctr encryption cipher
• aes192-ctr : Force ssh to use aes192-ctr encryption cipher
• aes256-ctr : Force ssh to use aes256-ctr encryption cipher
-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-md5: Force ssh to use hmac-md5 HMAC algorithm.
• hmac-md5-96: Force ssh to use hmac-md5-96 HMAC algorithm.
• hmac-sha1: Force ssh to use hmac-sha1 HMAC algorithm.
• hmac-sha1-96 : Force ssh to use hmac-sha1-96 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.
-v {1 | 2} (OPTIONAL) Enter the keyword -v then the SSH version 1 or 2. The default is the
version from the protocol negotiation.
Defaults As shown in the Parameters section.
