Priority
prioritizes intra-nodal traffic; the higher the number, the higher the priority. (This pri-
ority has no effect on traffic exiting a node.)

Bandwidth Allocation Group
assigns the LLC2 host to one of sixteen groups whose parameters regulate bandwidth
usage. See "Configuring Bandwidth Allocation Groups" on page 6-6.

Routing Subscriber ID
associates a Subscriber ID with the LLC2 host, and partially defines the local sub-
scriber IDs, all of which must begin with the

Source MAC Address Mask
is used to identify the FRX/FRM to inbound frames from a local LAN in an Originated
LLC2 session. Source address masks and host MAC addresses are placed in a for-
warding list that is checked by the software when a frame is received. If the MAC
address in an incoming frame matches a configured Source MAC Address Mask, the
frame will be passed through the node for transmission out the frame relay interface.

HSAP
is the service access point (SAP) address used to connect to the host. This must match
the SSAP (source SAP) in a frame received from the local LAN or the DSAP (desti-
nation SAP) in a frame from the remote link station.
