Parameters

server: Specifies a server by its IPv4 address or host name, a case-insensitive string of 1 to 253 characters.

port-number: Specifies the port number of the server, in the range of 1 to 65535. The default is 22.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the server belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters.

suite-b: Specifies the Suite B algorithms. If neither the 128-bit keyword nor the 192-bit keyword is specified, all algorithms in Suite B are used. For more information about the Suite B algorithms, see Table 62.

128-bit: Specifies the 128-bit Suite B security level.

192-bit: Specifies the 192-bit Suite B security level.

pki-domain domain-name: Specifies the PKI domain of the client's certificate. The domain-name argument represents the PKI domain name, a case-insensitive string of 1 to 31 characters. Invalid characters are tildes (~), asterisks (*), backslashes (\), vertical bars (|), colons (:), dots (.), angle brackets (< >), quotation marks ("), and apostrophes (').

server-pki-domain domain-name: Specifies the PKI domain for verifying the server's certificate. The domain-name argument represents the PKI domain name, a case-insensitive string of 1 to 31 characters. Invalid characters are tildes (~), asterisks (*), backslashes (\), vertical bars (|), colons (:), dots (.), angle brackets (< >), quotation marks ("), and apostrophes ('). If you do not specify the server's PKI domain, the client uses the PKI domain of its own certificate to verify the server's certificate.

prefer-compress: Specifies the preferred compression algorithm for data compression between the server and the client. By default, compression is not supported.

zlib: Specifies compression algorithm zlib.

dscp dscp-value: Specifies the DSCP value in the IPv4 SFTP packets. The value range for the dscp-value argument is 0 to 63, and the default value is 48. The DSCP value determines the transmission priority of the packet.

source: Specifies a source IP address or source interface for the SFTP packets. By default, the device uses the primary IPv4 address of the output interface in the routing entry as the source address of SFTP packets. As a best practice to ensure successful SFTP connections, specify a loopback interface as the source interface or specify the IPv4 address of the interface as the source IPv4 address.

• interface interface-type interface-number: Specifies a source interface by its type and number. The primary IPv4 address of this interface is the source IPv4 address of the SFTP packets.

• ip ip-address: Specifies a source IPv4 address.

Examples

# Use the 128-bit Suite B algorithms to establish a connection to SFTP server 10.1.1.2. Specify the client's PKI domain and the server's PKI domain as clientpkidomain and serverpkidomain, respectively.
