4.2 Latency/Jitter Test
The Latency/Jitter Test screen, is used to initiate tests that measure network latency, inter-frame
jitter and frame loss from the local 9145E10G to a remote unit. At the Diagnostics menu, select
Latency/Jitter Test (2) and press Enter. The Latency/Jitter Test screen (Figure 4-3.) opens.
NOTE: If the remote unit is a 9145, 9145E, or 9145E10G the latency and jit-
ter test results are more accurate since the time spent in the con-
trol plane of the remote unit iscanceled out.
Figure 4-3. Latency/Jitter Test Screen
Beneath the Maximum Latency and Maximum Jitter test results are the Far End P-Bit Sent/Rcvd,
Local P-Bit Sent/Rcvd, Far End DSCP Sent/Rcvd, and Local DSCP Sent/Rcvd. This data is used
to determine if the programmed Packet Priority or DSCP was changed during the Round Trip
between the local 9145E10G and the destination 9145E10G (far end). Only a 9145, 9145E, or
9145E10G destination can provide the Far End PBit/DSCP function.
NOTE: If the DF Bit is clear, the actual maximum packet size is 8192. The
DF Bit must be set for oversized packets greater than 1518 (payload
size greater than 1472) to be sent or the packet will be fragmented
(sent as multiple packets of size 1518).
