362 CHAPTER 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

Syntax sdlc mac-map remote mac-addr sdlc-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:
