• The number of allowable SSH connections is limited to the maximum number of vtys configured for
the device. Each SSH connection uses a vty resource.
• SSH uses either local security or the security protocol that is configured through AAA on your device
for user authentication. When configuring Authentication, Authorization, and Accounting ( AAA), you
must ensure that AAA is disabled on the console for user authentication. AAA authorization is disabled
on the console by default. If AAA authorization is enabled on the console, disable it by configuring the
no aaa authorization console command during the AAA configuration stage.
