timeout: 120 seconds.
Maximum authentication retries: 3
service port: 22
Command Mode Global configuration
Usage Guideline The command configures Secure Shell (SSH) server parameters on the switch.
The idle timer ("timeout" option) is refreshed when the SSH client sends the
message to the server. When the idle timer expires and the SSH server does not
receive any messages from the client, the session will be released.
The SSH server can be configured with extra authentication retries for setting up
an SSH session. The connection will be failed when the number of authentication
attempts equals the maximum number of authentication attempts (retries)
allowable.
Syntax Description

been idle for this timeout period.
