W e b S e r v e r I n t e r f a c e 3-19
N1 This counter indicates the number of “keep alive” status inquiries that are sent
between full status requests.
Values: 5–255
Default: 5
N2 The N2 counter specifies the total number of link reliability errors and
protocol errors that can occur during the sliding event monitor count defined
by N3. If this count is exceeded, the port is declared inactive.
Values: 1–255
Default: 3
N3 This counter represents a Monitored Events Count. For a network, a
monitored event is the receipt of a status inquiry message or the expiration of
the polling verification timer T2. For a FRAD, a monitored event is the
transmission of a status enquiry message. This parameter defines the size of
the sliding window used by the unit to determine whether a channel or user
device is active.
Values: 5–255
Default: 4
T1 This parameter specifies the number of seconds the unit waits between issuing
status inquiry messages.
Values: 5–30
Default: 10
RFC1315 Trap When this parameter is set to “Enable,” the unit will send the standard
RFC1315 frame relay DTE circuit state change trap every time a DLCI
changes state, provided at least one destination IP address for trap is
configured in the SNMP configuration.
Values: Disable, Enable
Default: Disable
Normal Tx Queue Size Each Frame Relay service has two distinct transmit queues: one for normal-
priority traffic and one for high-priority traffic. At this time, only TCP Server
traffic is considered high priority and is placed in the high-priority queue. All
other types of traffic are placed in the normal-priority queue.
This parameter defines how many normal priority frames can be put in front
of a high-priority frame. The software always checks for high-priority frames
before placing normal-priority frames in the transmit queue. However, once
the frames are in the hardware transmit queue, their order of transmission
cannot be changed.
If TCP Server is not up, set this parameter to 28 (the default). If TCP Server
is up, set this parameter according to the host system’s ability to support
higher latency. For example, if a host system has a timeout of 500 ms when
polling remote devices through a DDS Frame Relay service, the Normal Tx
Queue Size parameter should be set to 2. This would allow two 1500-byte IP
frames to be sent between frames without reaching the 500-ms limit. If the
host application has a timeout lower than 500 ms, this parameter should be set
