Q:

How many concurrent SSH sessions are supported and how to Kill a particular SSH session?



A:

Aruba HPE Switch allows 5 concurrent SSH sessions. Executing "show ip ssh" will show the list of active SSH session and using Kill command, user can kill any SSH session as needed.

 

  • Below example shows 5 active SSH sessions,

 

Sunill-3810M(config)# show ip ssh

  SSH Enabled     : Yes                 Secure Copy Enabled : No
  TCP Port Number : 22                  Timeout (sec)       : 120
  Rekey Enabled   : No                  Rekey Time (min)    : 60
                                        Rekey Volume (KB)   : 1048576

  • To kill any one or more, executing Kill <ssh session ID> will kill that particular session.
  • In the below example, session 6 was killed.


 

Sunill-3810M# kill 6
Sunill-3810M#

 

Sunill-3810M# show ip ssh
