  • 1.  [Q] How to get OOB on console port

    Posted 02-15-2016 07:01

    We have several floors with switches in the IDF's.

    I would like to know what your using to get to the console port on the different ports.

     

    Assume the switch uplink is down.

     

    thanks

    If you want true OOB for console port, then I would suggest terminal servers not connected to local switch revenue port, but instead true OOB network [for the terminal servers].

    Terminal server will allow for Async connect to console port and then also have an Ethernet connection to connect to an OOB switch network.  For true OOB you should not use the switches interfaces on the switch with the console connection for your Ethernet connection.  Through the terminal server you can connect remotely to the console port.

    OK, you know I have several floors with atleast 4 switches on each floor.

     

    If the term serv is in the server room, and the link is down to a switch on one of the floors, is this going to work.?

    This what a terminal server component is.  In general some number of RS-232/Serial ports (today 9 pin connector) and at least one Ethernet LAN interface:

    You then connect the LAN interface to some Ethernet network and access the various terminal servers remotely.  For true OOB you need a separate OOB network for this.  Some folks do this by connecting to a LAN port on the local switch, but when the switch may have a problem, defeats the purpose being able to get to the switch remotely, no matter what.

     

    Other remote mgmt option is using some in-band IP address on the switch(es) themselves.  For more on terminal servers go here:
