9-13
N3
is the number of Information LPDUs that will be received before sending an acknowl-
edgment. This parameter is used in conjunction with
T2
to allow stations to reduce
traffic. A counter is initialized to
N3
, and will be decremented by one each time a valid
sequential Information LPDU is received. When the counter reaches
0
an acknowl-
edgment is sent.
N3
is reset whenever an Information or Supervisory acknowledgment LPDU is sent by
the local station.
Tw
is the maximum number of sequentially numbered Information LPDUs that the link
station can have outstanding.
N2
is the maximum number of times that an LPDU (including Information LPDUs resent
after a checkpoint operation) will be sent following expiration of
T1
.
Priority
prioritizes intra-nodal traffic; the higher the number, the higher the priority. (This pri-
ority has no effect on traffic exiting a node.)
Priorities are configured on all logical interfaces that use a physical frame relay port.
The device processor in the node uses these priorities to help determine the order in
which it will process protocols.
Bandwidth Allocation Group
assigns the LLC2 host to one of sixteen groups whose parameters regulate bandwidth
usage. See "
Configuring Bandwidth Allocation Groups
" on page 7-6.
Suppress XIDs
prevents (if
Y
) the FRM from returning an XID in response to a null XID. This might
be desirable if the remote TPAD is not running PU 2.1. It should be noted that even if
an XID is sent, an SNRM (Set Normal Response Mode) immediately follows, so the
connection will be established.
