DLSw+ Support Matrix


Tables B-1 to B-5 in this appendix provide a description of the DLSw+ features, in what releases they are supported, and for what encapsulation types they are supported. In general, TCP/IP encapsulation provides the maximum functionality, but many features are still available if using other encapsulation types.

TCP encapsulation works with all the types of media combinations listed in Table B-1. Direct Encapsulation does not work with any of the media combinations except over:

Serial HDLC in Cisco IOS Release 10.3 and above

Frame Relay (with and without local acknowledgement) in Cisco IOS Release 11.0 and above

RSP support in Cisco IOS Release 11.1 and above

Table B-1 refers to the media in which the DLSw+ router is directly connected.
