Configure the address of an
secondary SDLC station
The following 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 derived from SDLC virtual MAC
address of the peer end and the SDLC address of the local end.
Follow these steps to configure the SDLC peer:

When specifying an SDLC peer MAC address for an SDLC virtual circuit, pay
attention to the difference between a token ring address and an Ethernet address:
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, revert each octet of the
■
Ethernet address, for example, convert 00e0.fc03.a548 to 0007.3fc0.a512, by
using the dlsw reverse command.
An XID is used to identify a device in an SNA system. When configuring an SDLC
connection, pay attention to the types of the connected SNA devices. Generally,
there are two types of devices in an SNA system: PU2.0 and PU2.1. An XID has
been configured on PU2.1 devices, so they can announce their identity by
exchanging the XID. A PU2.0 device does not come with an XID. Therefore, an XID
is not required on a PU2.1 device, but it is required on a PU2.0 device.
Follow these steps to configure an SDLC XID:
