Trying to find a Cisco UniverCD URL with SNA LLC (in case the stress makes us forget) I found this:

access-list 202 permit 0x0404 0x0001 ! Permits SNA frames (command or response)

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fibm_c/bcfpart1/bcfsrb.htm#1005047

I was used to see 0x0000 0x0d0d, which allows SNA 0, 4, 8 and C. Why 0404 is used by Cisco in this example?
