RFC 2166 - DLSw v2.0 Enhancements
RFC 1795 defines the use of two unidirectional TCP/IP sessions
between any pair of DLSw peers using read port number 2065 and write
port number 2067. Additionally, RFC 1795 allows for implementations
to optionally use only one bi-directional TCP/IP session. Using one
TCP/IP session between DLSw peers is believed to significantly
improve the performance and scalability of DLSw protocols.

Subject: DLSW port 2067
Does anybody know what TCP port 2067 does in relation to DLSW. I have
read and re - read my SNA notes and I cannot see any reference to this
port . I know it has some part in DLSW ,if you issue a show ip socket on
a router running DLSW you will see an open socket for 2067. see below
fred#sh ip sock
