GNS serial connections

Posted on 2011-10-07

I tried to change the WIC within the slots tab, within GNS 3, and it appears as though the WIC seems to be "grayed out".  I tried this on the 3600 and 3700 routers.

I tried both when the device is stopped and when it's started.

How do I fix this?

    If you look at you'll see that the 3600 doesn't have any. The 37xx should have though. Just checked it on a 3745. What version are you using?

    If I am not mistaken, even the 3600 series have the serial interfaces.

    Hello Claricccccccccccccccccccccce ;)

    Well I checked, in my version (thought it was 0.7.3) the 3600 doesn't have wic options.

    Well serial is serial....
    The way it is seen in a cisco depends on the hardware (modular, etc.). This is just a matter of notation and it shouldn't matter if it is s1, s0/1 or s0/0/1. the functionality remains the same.

    Okay, the 3600 series does not have  WIC, but they do have the NM-4T that is four serial interfaces. Regardless, like Ernie stated the numbering is not all that important.
