Frame Relay Port Parameters
1 If se t to Y, no back up D LCIs on this p ort wi ll be used (even if the port is enab led vi a
on-line port enable).
2 If one physical frame relay port will connect to several remote sites, be sure the l ine
speed is adequately higher that the speeds configured on the remote sites.
3 If this port will connect to a frame relay network, set Logical DCE to N. Also no te tha t
one end of a frame relay backup connection must be configured as l ogical DCE.
4 Not applicable to CSU/DSU ports.
5 This p arame ter is relev ant on ly if Physical Po rt Interface is s omething other than RS-
232 an d Generate Clock is Y.
6 Appli cable only to CSU /DSU por ts.
7 These parameters are relevant only if Link La ye r Ma nage m ent is LMI or ANNEXD and
Logical DCE is N.
8N3 should be greater than or equal to N2.
9 If Link Layer Management is
none, this parameter is irrelevant. (If Link Layer Man-
agement is changed to none from some other value, the default for N2 will be left as it
was before the change.)
10 T2 shou ld be great er tha n or eq ual to T1.
11 This parameter is relevant only if Logical DCE is Y.
