362CHAPTER 21: BASIC DLSW CONFIGURATION COMMANDS

Use the undo sdlc mac-map local command to delete the configured SDLC virtual MAC address.

By default, no SDLC virtual MAC address is configured.

Initially designed for LLC2 protocols, DLSw establishes mappings with virtual circuits through MAC addresses. Therefore, a MAC address must be specified for an SDLC virtual circuit so that SDLC frames can be forwarded. This command is used to assign the current interface a virtual MAC address, which will serve as the source MAC address during the conversion of SDLC frames to LLC2 frames.

n Note that the sixth byte of the MAC address should be set to 0x00. The system will combine the first five bytes of this virtual MAC address with the SDLC address into a new MAC address, which will serve as the source MAC address in SDLC-to-LLC2 frame format conversion.

Example # Set the SDLC virtual MAC address to 0000-e81c-b600 on Serial 2/0.

<Sysname> system-view

[Sysname] interface serial 2/0

[Sysname-Serial2/0] sdlc mac-map local 0000-e81c-b600

sdlc mac-map remote

Syntax sdlc mac-map remote mac-addrsdlc-addr

undo sdlc mac-map remote mac-addrsdlc-addr

View Synchronous serial interface view

Parameter mac-addr: MAC address of the SDLC peer to be configured.

sdlc-addr: SDLC address of the SDLC peer to be configured, in the range of 0x01 to 0xFE.

Description Use the sdlc mac-map remote command to configure an SDLC peer.

Use the undo sdlc mac-map remote command to delete an SDLC peer.

By default, the synchronous serial interface has no remote peer.

This command is used to specify the MAC address of the corresponding peer end for an SDLC virtual circuit so as to provide the destination MAC address for SDLC-to-LLC2 frame conversion. In DLSw configuration, a peer should be configured for each SDLC address. The MAC address of the peer should be the MAC address of the remote SNA device (physical address in the Ethernet or Token Ring format), or the compound MAC address obtained from SDLC virtual MAC address of the peer end and the SDLC address of the local end.

In this configuration, pay attention to the difference in bit order between token ring address and an Ethernet address:
