Understanding the differences between the DSAP and SSAP, I was not under
the impression Mariusz was asking for a DSAP/SSAP specific filter, but
an LSAP filter which could apply to both DSAP and SSAP values.
I have found that being more specific sometimes is not to your
advantage... Unless specifically asked.
For example, I might be asked to filter without using an LSAP filter.
Another way of saying this is to filter on the DSAP without an LSAP
filter. In this case, I would just use and icanreach, or icannotreach
(as required) with the appropriate DSAP value. Or, if asked to filter
on DSAP in an LSAP filter, use the even DSAP values as you pointed out.
If this is not correct please clarify for my edification.

Mariusz is wright.
NetBios: 0xF0F0 0x0001, DSAP is F0 and SSAP can be F0 or F1.
Kind Regards,
I die. I fracture into thousands of fragments of flushed embarrassment.
My body parts fly, connectionless, over a badly constructed spanning
tree that isn't quite loop free.
I fall screaming into 127.0.0.1.

I think that :
SNA: ( I saw two versions depending how accurate you'd like to be :) )
0x0000 0x0d0d <-- more general,
0x0404 0x0001 <-- more specific (if ethernet segment is what you are
asked about)
NetBios:
0xF0F0 0x0001
