You need to specify adapter addresses for frame relay.
The frame-relay communications input-output processor (IOP) is not given a preset, or burned-in, adapter address. You must specify this address for the local adapter address (ADPTADR parameter) on token-ring, distributed data interface (DDI), and Ethernet line descriptions used for bridged frame-relay connections. Configure the frame-relay adapter address the same as for locally attached local area network (LAN) lines. Systems Network Architecture (SNA) or IP direct configurations do not require the local adapter address.
You must configure the remote adapter address (ADPTADR parameter on the controller description) to match the adapter address of the remote system.
SNA direct frames do not include adapter addresses. You do not need to configure the adapter address for frame-relay line descriptions or for controllers that specify LINKTYPE(*FR).
