Changing SSH Protocols
By default, SafeGuard OS supports both SSH versions 1 and 2. The protocols can be
deleted or added as necessary by explicitly defining one or both. Use the ip ssh protocol
command in Global Configuration mode to change the protocol support.
ip ssh protocol protocol_level {protocol_level}
The following example limits the SSH protocol to SSH version 2:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #ip ssh protocol 2
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
Limiting SSH Sessions
The default for SSH sessions is set to the maximum of 5 sessions. To reduce the number of
sessions, in Global Configuration mode use the ip ssh maxsessions command.
ip ssh maxsessions sessions
The following example limits the SSH sessions to 3:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #ip ssh maxsessions 3
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
