A company has a network that includes HP 5800 and 12500 switches. Usage demands on the
company’s FTP servers have increased, causing performance issues during peak usage times.
While analyzing link utilization, the network administrator noticed that the most heavily utilized
links experience bursts of congestion, causing them to drop traffic. The links then experience brief
periods of low utilization followed by another burst of congestion. This pattern continues
periodically throughout the peak utilization time.
What should the network administrator do to attempt to create a more efficient traffic pattern on
these links?
A.
Configure an outbound traffic policing policy on the ports in question, setting the CIR at about
sixty percent of the ports’ capacity and the PIR at about eighty percent.
B.
Apply Weighted Fair Queuing (WFQ) or Weighted Round Robin (WRR) scheduling in
preference to Strict Priority (SP) scheduling on the ports in question.
C.
Configure inbound traffic policing policies on ports at the core, setting the CIR at about sixty
percent of the ports’ capacity and the PIR at about eighty percent. Apply outbound generic traffic
shaping (GTS) on ports facing the core ports, setting the CIR equal to the CIR on the core ports.
D.
Apply a WRED table to the ports in question, optionally adjusting the table values to drop lower
priority traffic first.
