Parameter DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch Description SSH Server Status Use the pull-down menu to enable or disable SSH on the Switch. The default is Disabled. Max Session (1-8) Enter a value between 1 and 8 to set the number of users that may simultaneously access the Switch. The default setting is 8. Time Out (120-600) Allows the user to set the connection timeout. The user may set a time between 120 and 600 seconds. The default setting is 120 seconds. Auth.
