Parameter Description
Encapsulation
Type RFC1490 - IETF is the standard used by most equipment. The Cisco option should be used
when the PR is communicating with a router configured to use the default Cisco standard.
SNAP IP Indicates that the Sub-Network Access Protocol should be used. The router on the sending
end must be using the same header type (NLPID or SNAP) as the router on the receiving
end. See the CyROS Reference Guide for more information.
LMI Selects the Local Management Interface specification to be used. ANSI , Group of Four
(defined by the vendors that first implemented Frame Relay), Q933a (defined by ITU-T), and
None (used for a dedicated FR connection without a network).
T391 Interval between the LMI Status Enquiry messages.
N391 Full Status Polling Counter. Full Status Enquiry messages are sent every N391-th LMI Status
Enquiry message.
N392 Error Threshold. The network counts how many events occur within a given period and
considers an interface inactive when the number of events exceeds a threshold.
N393 is the
number of events to be considered and N392 the number of errors within this period. If N392
of the last N393 events are errors, the interface is deemed inactive. A successful event is the
receipt of a valid Status Enquiry message
N393 Monitored Events Count. See the description of N392 . This value must be larger than N392.
