Cannot access management SSH/HTTPS while on WLAN

  • 1.  Cannot access management SSH/HTTPS while on WLAN

    Posted Jun 24, 2019 05:16 PM

    I have two 7205-US controllers in an HA active/standby pair.  While on a wired connection I am able to access the management interface over SSH/HTTPS of both.  While on the internal WLAN I am unable to access either the SSH interface or HTTPS interface.

     

    I ran a packet capture and I see the HTTPS session establishes a TCP 3 way handshake, so there appears to be bidirectional routing working.  Once I sent the TLS 1.2 Client Hello, I get no further response from the controller.  TCP retransmissions occur until the client finally sends a TCP reset, tearing the session down.

     

    I'm unsure why this is happening as I can access the secondary (passive) controller on the WLAN without issue.  Is there anything specifically that would cause this in terms of settings to prevent/deny a user access to the management interface?

    What role are you assigned, and what are the rules within the role?

     

    "show user" will list users and roles.

     

    "show rights <rolename>" will display the role, policies, and rules.

     

    "show datapath acl id <ACL #" displays how controller sees rules (ACL # can be found in "show rights <rolename>" command

     

    You can also check the firewall hits to see if one is blocking it.

     

    Also, what OS version?

     

    I hope this helps,
