Use sftp ipv6 to connect an SFTP client to an IPv6 SFTP server and enter SFTP client view.

Syntax

In non-FIPS mode:

sftp ipv6 server [ port-number ] [ vpn-instance vpn-instance-name ] [ -i interface-type interface-number ] [ identity-key { dsa | ecdsa-sha2-nistp256 | ecdsa-sha2-nistp384 | rsa | { x509v3-ecdsa-sha2-nistp256 | x509v3-ecdsa-sha2-nistp384 } pki-domain domain-name } | prefer-compress zlib | prefer-ctos-cipher { 3des-cbc |aes128-cbc | aes128-ctr | aes128-gcm | aes192-ctr | aes256-cbc | aes256-ctr | aes256-gcm | des-cbc } | prefer-ctos-hmac { md5 | md5-96 | sha1 | sha1-96 | sha2-256 | sha2-512 } | prefer-kex { dh-group-exchange-sha1 | dh-group1-sha1 | dh-group14-sha1 | ecdh-sha2-nistp256 | ecdh-sha2-nistp384 } | prefer-stoc-cipher { 3des-cbc |aes128-cbc | aes128-ctr | aes128-gcm | aes192-ctr | aes256-cbc | aes256-ctr | aes256-gcm | des-cbc } | prefer-stoc-hmac { md5 | md5-96 | sha1 | sha1-96 | sha2-256 | sha2-512 } ] * [ dscp dscp-value |{ public-key keyname | server-pki-domain domain-name } | source { interface interface-type interface-number | ipv6 ipv6-address } ] *

Parameters

server: Specifies a server by its IPv6 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.

-i interface-type interface-number: Specifies an output interface by its type and number for IPv6 SFTP packets. This option is used only when the server uses a link-local address to provide the SFTP service for the client. The specified output interface on the SFTP client must have a link-local address.

identity-key: Specifies a public key algorithm for publickey authentication of the client. The default is DSA in non-FIPS mode and is RSA in FIPS mode. If the server uses publickey authentication, you must specify this keyword. The client generates the digital signature or certificate by using the local private key that is associated with the specified algorithm.

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.

prefer-ctos-cipher: Specifies the preferred client-to-server encryption algorithm. The default is AES128-CTR. Supported algorithms are DES-CBC, 3DES-CBC, AES128-CBC, AES128-CTR, AES128-GCM, AES192-CTR, AES256-CBC, AES256-CTR, and AES256-GCM, in ascending order of security strength and computation time.

prefer-ctos-hmac: Specifies the preferred client-to-server HMAC algorithm. The default is SHA2-256. Supported algorithms are MD5, MD5-96, SHA1, SHA1-96, SHA2-256, SHA2-512, in ascending order of security strength and computation time.

prefer-kex: Specifies the preferred key exchange algorithm. The default is ecdh-sha2-nistp256. Supported algorithms are diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, ecdh-sha2-nistp256, and ecdh-sha2-nistp384, in ascending order of security strength and computation time.

prefer-stoc-cipher: Specifies the preferred server-to-client encryption algorithm. The default is AES128-CTR. Supported algorithms are the same as the client-to-server encryption algorithms (see the prefer-ctos-cipher keyword).

prefer-stoc-hmac: Specifies the preferred server-to-client HMAC algorithm. The default is SHA2-256. Supported algorithms are the same as the client-to-server HMAC algorithms (see the prefer-ctos-hmac keyword).

dscp dscp-value: Specifies the DSCP value in the IPv6 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.

public-key keyname: Specifies the host public key of the server that the client uses to authenticate the server. The keyname argument is a case-insensitive string of 1 to 64 characters.

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 (').

source: Specifies a source IPv6 address or source interface for IPv6 SFTP packets. By default, the device automatically selects a source address for IPv6 SFTP packets in compliance with RFC 3484. As a best practice to ensure successful SFTP connections, specify a loopback interface as the source interface or specify that interface's IPv6 address as the source IPv6 address.

Usage guidelines

If the client and the server have negotiated to use certificate authentication, the client must verify the server's certificate. For the client to correctly get the server's certificate, you must specify the server's PKI domain on the client by using the server-pki-domain domain-name option. The client uses the CA certificate stored in the specified PKI domain to verify the server's certificate and does not need to save the server's public key before authentication. 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.

Examples

# Connect an SFTP client to SFTP server 2000::1 and specify the public key of the server as svkey. The SFTP client uses publickey authentication. Use the following algorithms:

<Sysname> sftp ipv6 2000::1 prefer-kex dh-group14-sha1 prefer-stoc-cipher aes128-cbc prefer-ctos-hmac sha1 prefer-stoc-hmac sha1-96 prefer-compress zlib public-key svkey
