A network administrator uses IP SLA to measure UDP performance and notices that packets on
one router have a higher one-way delay compared to the opposite direction. Which UDP
characteristic does this scenario describe?
A.
latency
B.
starvation
C.
connectionless communication
D.
nonsequencing unordered packets
E.
jitter
IOS IP SLAs provides a proactive notification feature with an SNMP trap. Each measurement operation can monitor against a pre-set performance threshold. Cisco IOS IP SLAs generates an SNMP trap to alert management applications if this threshold is crossed. Several SNMP traps are available: round trip time, average jitter, one-way latency, jitter, packet loss, MOS, and connectivity tests.
Here is a partial sample output from the IP SLA statistics that can be seen:
