Configuring Data-Link Switching Plus

DLSw+ Configuration Task List

Ethernet

Traffic that originates from Ethernet is picked up from the local Ethernet interface bridge group and transported across the DLSw+ network. Therefore, you must map a specific Ethernet bridge group to DLSw+.

To map an Ethernet bridge group to DLSw+, use the following command in global configuration mode:

Command	Purpose
Router(config)# dlsw bridge-group group-number	Links DLSw+ to the bridge group of the Ethernet LAN.
[llc2 [N2 number] [ack-delay-time milliseconds]
[ack-max number] [idle-time milliseconds]
[local-window number] [t1-time milliseconds]
[tbusy-time milliseconds] [tpf-time
milliseconds] [trej-timemilliseconds]
[txq-max number] [xid-neg-val-time milliseconds]
[xid-retry-time milliseconds]] [locaddr-priority
lu address priority list number] [sap-priority
priority list number]

To assign the Ethernet interface to a bridge group, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)# bridge-groupbridge-group	Assigns the Ethernet interface to a bridge group.

The following command maps bridge-group 1 to DLSw+:

dlsw bridge-group 1 int E1

bridge-group 1 bridge 1 protocol ieee

SDLC

Configuring SDLC devices is more complicated than configuring Ethernet and Token Ring. There are several considerations that affect which interface commands are configured. See the DLSw+ Design and Implementation Guide for more details.

To establish devices as SDLC stations, use the following commands in interface configuration mode:

	Command	Purpose
Step 1
	Router(config-if)# encapsulation	Sets the encapsulation type of the serial interface to SDLC.
	sdlc
Step 2
	Router(config-if)# sdlc role {none	Establishes the role of the interface.
	primary secondary prim-xid-poll}
Step 3
	Router(config-if)# sdlc vmac	Configures a MAC address for the serial interface.
	mac-address1
Step 4	Router(config-if)# sdlc address	Assigns a set of secondary stations attached to the serial link.
	hexbyte [echo]
Step 5
	Router(config-if)# sdlc partner	Specifies the destination address with which an LLC session is
	mac-address sdlc-address {inbound	established for the SDLC station.
	outbound}
