HP (Hewlett-Packard) 200 Network Router User Manual


 
Note: Because this parameter uses the ‘‘Clock Speed’’ of the WAN circuit configured
in the Lines configuration to calculate the maximum number of bytes queued to the
WAN circuit, be sure to enter the Clock Speed accurately even when an External
Clock source is used. During router boot sequence, an event is logged to show the
calculated latency cap and the parameters in effect.
If Max Link Latency is set to zero (0), there is no latency limit. As packets are
queued for transmission over the WAN circuit, the router counts the number of bytes
in the queued packets. Before a packet is added to the queue, the router checks to
make sure that the number of bytes in the packet plus the current number of bytes
queued does not exceed the latency cap. If the sum exceeds the cap, the packet is
dropped. When a packet is dropped, the ‘‘latency_tx’’ MIB variable is incremented
and, on the first drop of a packet, an event is logged.
Max Pkt Size
or
Maximum Packet Size
Determines the largest packet size handled by the Frame Relay network or the
maximum size of an SMDS packet transmitted by the router or the largest packet
size accepted by Point-to-Point from the peer router.
SMDS Default: 1547
Point-to-Point Default: 1578
Frame Relay Default: 1600
Min Channels to
Aggregate
Sets the lower limit for the number of channels your terminal adapter uses to make a
connection. (For further information, refer to the instruction manual for your
terminal adapter).
Min Frame Spacing
Used with Pt to Pt Protocol (PPP) to determine the minimum number of eight-bit
flag sequences prefixed to an HDLC packet transmitted by the router. The packet
ends with a single instance of the same flag. The total number of of flags transmitted
between sequential packets includes the trailing flag and the variable number of
leading flags. After determining the minimum number of leading flags (not including
the trailing flag) needed, select the closest available value.
Default: 2
Range: 2 to 62 (in increments of 2)
