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:
To assign the Ethernet interface to a bridge group, use the following command in interface configuration
mode:
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
Router(config)# dlsw bridge-group group-number
[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-time milliseconds]
[txq-max number] [xid-neg-val-time milliseconds]
[xid-retry-time milliseconds]] [locaddr-priority
lu address priority list number] [sap-priority
priority list number]
Links DLSw+ to the bridge group of the Ethernet LAN.
Command Purpose
Router(config-if)# bridge-group bridge-group
Assigns the Ethernet interface to a bridge group.
Command Purpose
Step 1
Router(config-if)# encapsulation
sdlc
Sets the encapsulation type of the serial interface to SDLC.
Step 2
Router(config-if)# sdlc role {none |
primary | secondary | prim-xid-poll}
Establishes the role of the interface.
Step 3
Router(config-if)# sdlc vmac
mac-address
1
Configures a MAC address for the serial interface.
Step 4
Router(config-if)# sdlc address
hexbyte [echo]
Assigns a set of secondary stations attached to the serial link.
Step 5
Router(config-if)# sdlc partner
mac-address sdlc-address {inbound |
outbound}
Specifies the destination address with which an LLC session is
established for the SDLC station.
