dlsw reverse

Syntax dlsw reverse mac-address

View System view

Parameter mac-address: MAC address to be converted.

Description Use the dlsw reverse command to convert a MAC address from the Ethernet format to the token ring format, or vice versa.

When specifying an SDLC peer MAC address for an SDLC virtual circuit, pay attention to the following situations:

■If the remote SNA device uses a token ring address, specify its MAC address directly.

■If the remote SNA device uses an Ethernet address, convert the Ethernet address to a token ring address by using the dlsw reverse command. For example, convert 00e0.fc03.a548 to 0007.3fc0.5a12.

■If the remote SNA device uses an SDLC link, specify a compound MAC address, in which the first five bytes are from the virtual MAC address configured in the sdlc mac-map local command on the remote router, and the last byte is the SDLC address of the local router.

Related command: sdlc mac-map remote.

Example # Convert the Ethernet format MAC address 0012-3578-4521 to the token ring format.

<Sysname> system-view

[Sysname] dlsw reverse 0012-3578-4521

Reversed MAC address: 0048-ac1e-a284

# Convert the token ring MAC address 0048-ac1e-a284 to the Ethernet format.

[Sysname] dlsw reverse 0048-ac1e-a284

Reversed MAC address: 0012-3578-4521

dlsw max-transmission

Syntax dlsw max-transmission retries

undo dlsw max-transmission

Parameter retries: The maximum number of attempts that the DLSw v2.0 router should make

to send an explorer frame. It ranges from 1 to 10 and defaults to 5.
