Re: configure dlsw for only allow SNA and netbios with a BVI int

You can restrict the traffic passed by DLSW to specific SAP values by using the 'lsap-output-list' parameter on the dlsw remote-peer command with an access list.

The following access list

access-list 200 permit 0x0000 0x0d0d

access-list 200 permit 0xf0f0 0x0101

access-list 200 deny 0x0000 0xffff

will permit all SNA saps (multiples of 4) and netbios ( F0 ) and deny all other traffic.
