Starting and Managing Secure (SSH) Access Sessions Between
Switches
Starting with Release 5, Cisco MGX switches support secure sessions between switches. For example,
you can start a CLI session with one switch, then establish a secure session with another switch, and later
terminate the second session and return to the first. The following sections describe:
•
Starting a Secure Session Between Switches
•
Returning to the Previous Session
Tip
For instructions on establishing a secure session between a workstation and a switch, see
Appendix C, “Supporting and Using Additional CLI Access Options.”
The section on establishing secure sessions from a workstation contains additional information on the
secure session feature.
