7800 Extension Switch - GE interfaces

    Posted 09-20-2013 08:09 AM

    Hi,

    Looking for assistance if anyone can help.

    I'm looking to understand and confirm that the GE interfaces of a 7800 Extension Switch require to be within it's own subnet.  I'm having trouble locating this information within the vast number of reference material available.


    Any help appreciated


    Regards


    David

    Apologies for the vagueness of the request, hopefully this will help to make more sense of my request

    I currently have a couple of paired 7800 extension switches in 2 sites that have been connected to our IP Network via the 2 on board copper ports, we have recently purchase additional bandwidth between sites and are required to plug in additional copper connections to our IP Network to take advantage of this.  The presentation at the moment looks like

    Local Site                                                        Remote Site

    ge 0 - 192.168.0.1 ------------------------------------ 192.168.0.2 - ge 0

    ge 1 - 192.168.1.1 ------------------------------------ 192.168.1.2 - ge 1

    If i was to cable additional ge ports up for use within new tunnels on the switches would i have to assign a unique IP subnet to each port such as

    Local Site                                                        Remote Site

    ge 0 - 192.168.0.1 ------------------------------------ 192.168.0.2 - ge 0

    ge 1 - 192.168.1.1 ------------------------------------ 192.168.1.2 - ge 1

    ge 2 - 192.168.2.1 ------------------------------------ 192.168.2.2 - ge 2

    ge 3 - 192.168.3.1 ------------------------------------ 192.168.3.2 - ge 3

    or can i assign ip's from the same subnet

    Local Site                                                        Remote Site

    ge 0 - 192.168.0.1 ------------------------------------ 192.168.0.2 - ge 0

    ge 1 - 192.168.0.3 ------------------------------------ 192.168.0.4 - ge 1

    ge 2 - 192.168.0.5 ------------------------------------ 192.168.0.6 - ge 2

    ge 3 - 192.168.0.7 ------------------------------------ 192.168.0.8 - ge 1

    The upgrade license has been purchased to make use of the additional fiber/ge ports but we have not purchased the integrated routing or advanced extension licenses.

    I hope that makes more sense

    David,

    in some circumstance via FCIP in order to allow multiple IP source and destination Address - please refer release notes - , a "Advanced Extension" License is required.

    Integrated Routing is required if you want to set a any Port as EX or VEX Port.

    About you question,

    as per subnet definitions:

    1) is Subnet IP

    2) is Subnet mask

    apparently you asking for Subnet IP

    I preferred to use as suggested by Brocade different source/destination IP for each Tunnel / Physical Port in example:

    ge 0 - 192.168.10.1 ------------------------------------ 192.168.110.1 - ge 0

    ge 1 - 192.168.20.1 ------------------------------------ 192.168.120.1 - ge 1

    ge 2 - 192.168.30.1 ------------------------------------ 192.168.130.1 - ge 2

    and so on.

    Hi,

    Thank you for assistance so far.

    Do you know if that recommendation has been written down within any published guides at all?

    Regards
