Configuring DLSw Services

You can also prioritize trafﬁc based on any values within the headers and data

packets.

For detailed information about DLSw prioritization, refer to Chapter 6, “Using

DLSw Prioritization.”

Protocol Prioritization

You can use protocol prioritization to transmit DLSw trafﬁc before other trafﬁc on

an individual synchronous line interface. This is done by creating a ﬁlter, as

follows:

• Criteria = TCP source port

• Range = 2065 - 2067

• Action = high queue

This ensures that SNA and NetBIOS trafﬁc receive preference on the network. For

more information on how to access and conﬁgure trafﬁc ﬁlters for DLSw services,

refer to Chapter 6, “Using DLSw Prioritization.”

DLSw and Related Protocols

DLSw uses the services of lower layer subsystems, depending on the type of

interface being conﬁgured and the services required. Related subsystems include

• Physical interface: Token Ring, Ethernet, WAN, FDDI, etc.

• Transport services: Source Route Bridging, Transparent Bridging, Frame

Relay, etc.

• Data Link Control services: LLC2, SDLC

• TCP/IP services (dual switch only)
