The UDP stuff is for non-critical traffic, such as "canureach" and things
like that...

Subject: DLSW UDP ports
I was doing a packet capture between two routers to compare DLSw ports. I
was searching the archives when I ran across this post from Scott Morris:
-----------------------------------------------------------------------
Well... Those aren't exactly helpful as they are the original RFC
implementation of DLSW. But a good idea to look there anyway!
Access-list 100 deny tcp any range 11000 11999 any eq 2065 (incoming)
Access-list 100 deny tcp any eq 2065 any range 11000 11999 (outgoing)
Access-list 100 deny udp any eq 0 any eq 2067 (incoming) Access-list 100
deny udp any eq 2067 any eq 0 (outgoing) Access-list 100 permit ip any any
The original way was from 2067 to 2065 both ways.

I was able to see the tcp ports and the tcp keepalives; however, I didn't
get a chance to establish a ciruit between two computers. Can I assume that
the UDP ports are for explorer traffic? (I will lab this up when I get a
chance.)
