The THRESHOLD SET-UP MENU allows the traffic load conditions and stability timers for activating and
deactivating the secondary link to be set.
1- Up Threshold
The Up Threshold value determines the percentage of primary link's capacity that will cause the secondary link to be
activated. The primary link must sustain a throughput (either receive or transmit) of greater than the up threshold for a
period greater than the up stability timer in order for the secondary link to be activated.
Enter:
Percent of main link capacity (from 50 to 100)
> 80
Default:
80%
Note:
In a frame relay environment, the link summary statistics used to determine the up threshold may not be
accurate due to the overhead associated with frame relay. The overhead typically adds about 5% at an 80%
line load, meaning setting the up threshold at 80% would cause the secondary link to come up when the
actual transmission rate reaches about 85% of the maximum line rate. If a more accurate data transmission
threshold is required, it may be calculated by using the Frame Relay Protocol Statistics. Go to the Main
Menu/Statistics/WAN Statistics/Remote Site Statistics/Protocol Statistics and page down to the FR
display. Take the greater of the Rcv or Xmt rate (in KB) and divide it by the stated link speed (in KB) *100
to get the recent percent of the link capacity being used for data. By comparing this to the load shown in
the Link Summary Statistics, the amount of overhead may be determined and the threshold adjusted
accordingly.
