Configuring an SDLC peer
You can specify the MAC address for the peer end of an SDLC virtual circuit, and the MAC address is used as the destination MAC address of the LLC2 frames converted from SDLC frames. 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 derived from the SDLC virtual MAC address of the peer end and the SDLC address of the local end.
When specifying an SDLC peer MAC address for an SDLC virtual circuit, follow these guidelines:
If the remote SNA device uses a token ring address, use its token ring address directly.
If the remote SNA device uses an Ethernet address, convert the Ethernet address to a token ring address, for example, convert 00e0.fc03.a548 to 0007.3fc0.5a12, by using the dlsw reverse command.
If the remote SNA device uses an SDLC link, specify a compound MAC address, where the first 5 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.
To configure an SDLC peer:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Configure MAC address conversion between Ethernet and token ring formats. | dlsw reverse mac-address | Optional. |
3. Enter interface view. | interface interface-type interface-number | N/A |
4. Configure an SDLC peer. | sdlc mac-map remote mac-addr sdlc-addr | By default, no SDLC peer is configured. |
