Information about SSH
Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. SSH provides more
security for remote connections than Telnet does by providing strong encryption when a device is authenticated.
This software release supports SSH Version 1 (SSHv1) and SSH Version 2 (SSHv2).
SSH and Switch Access
For SSH configuration examples, see the "SSH Configuration Examples" section in the "Configuring Secure
Shell" section in the "Other Security Features" chapter of the Cisco IOS Security Configuration Guide, Cisco
IOS Release 12.4.
SSH functions the same in IPv6 as in IPv4. For IPv6, SSH supports IPv6 addresses and enables secure,
encrypted connections with remote IPv6 nodes over an IPv6 transport.
