Secure protocol support (Continued)

TABLE 28

Protocol Description

SSH

Secure Shell (SSH) is a network protocol that allows data to be exchanged over a secure channel
between two computers. Encryption provides confidentiality and integrity of data. SSH uses public-key
cryptography to authenticate the remote computer and allow the remote computer to authenticate the
user, if necessary.

SSL

Fabric OS uses Secure Socket Layer (SSL) to support HTTPS. A certificate must be generated and
installed on each switch to enable SSL. Supports SSLv3, 128-bit encryption by default. Also supports
TLSv1.0 and TLSv1.2.

Table 29

describes additional software or certificates that you must obtain to deploy secure protocols.

Comments

Nonsecure Nonsecure

No special setup is needed to use Telnet or HTTP.

Nonsecure Secure

Secure protocols may be used. An SSL switch certificate must be installed if
HTTPS is used.

Secure

Secure

Switches running earlier Fabric OS versions can be part of the secure fabric,
but they do not support secure management.

Secure management protocols must be configured for each participating
switch. Nonsecure protocols may be disabled on nonparticipating switches.

If SSL is used, then certificates must be installed. For more information on
installing certificates, refer to

Installing a switch certificate

on page 181.

Secure

Nonsecure

You must use SSH because Telnet is not allowed with some features.
