I'm not clear on the details, but many Cisco switches wait for 15-30
seconds after the link comes up before passing traffic. This is to snoop
for STP traffic before the link is established.

There is a configuration option to turn it off for a specific port, but
again, I don't remember the details.

Hope it helps,
