The number of active SSH sessions between remote SSH clients and the SSH server on the device.
Maximum number of SSH
Sessions Allowed
The maximum number of SSH sessions that may be connected to the device simultaneously.
SSH Session Timeout

the device, which might be
Present
,
Absent
, or
Generation in Progress
. Use the buttons as follows:
Click to download an SSH-1 RSA or SSH-2 RSA key file from a remote system. In the

Telnet Session Configuration
Telnet is a terminal emulation TCP/IP protocol. ASCII terminals can be virtually connected to the local device
through a TCP/IP protocol network. Telnet is an alternative to a local login terminal where a remote login is
required. The switch supports up to five simultaneous Telnet sessions. All CLI commands can be used over a
Telnet session.
The
Telnet Session Configuration
page lets you control inbound Telnet settings on the switch. Inbound Telnet
sessions originate on a remote system and allow a user on that system to connect to the switch CLI. To
display the
Telnet Session Configuration
page, click
System
>
Management
Access
>
Telnet
in the navigation
menu.
