system MTU settings

Hi Sirs,

Just have question on the system MTU command on the switches for the lab; if I set the system mtu 1504 on 2 switches, do I need to set them on the other 2 switches as best practice?  This question is related to dot1q tunnelng on IE vol 2 labs where setting the system mtu to 1504 on just the switches using dot1q tunnel.

If i do not set the same system mtu on the other switches, what are the ramifications on the l2 perspective?  

Thanks in advance.

  • On the devices that NEED to carry the extra tag, I'd say yes. The ones
    that do not, there's no bother. With that, make sure your L2 path goes
    the way you want!

    On the other hand, it doesn't harm anything (at least until you hit
    OSPF) to change them on all switches. :)

    Choice!
