newbie question on link status

Hi,

Does weather map link arrow change color when the link is down?

Thanks,

It depends.

If you are just graph traffic, then you will have 0 traffic at that point, so yes, it will go grey (with the default colour scheme). Even a completely idle link sends ARPs, and various other keepalive traffic, so it's rare for a line to be up and have 0 traffic.

Thanks for your reply. Just one more question, those arrow can make blinking if the link has no traffic or can customize color?
Thanks in advance.

You can customize the colour with the SCALE keyword

e.g.

SCALE DEFAULT 0 0 255 0 0

would make the link go red when there is *exactly* 0 traffic.

You can't make anything blink.
