Refer to the exhibit.
This HP 10500 Switch Series is receiving an average of 1 Gbps of HTTP traffic from 10.1.4.0/24.
The switch starts to receive an additional 1 Gbps of HTTP traffic from 10.1.4.0/24. How does the
switch handle the traffic?
A.
It drops the traffic
B.
It forwards the traffic but marks it yellow (for a higher drop precedence)
C.
It forwards the traffic without remarking it in any way
D.
It forwards the traffic but marks it for forwarding in a lower priority queue
Explanation:
Parameters
cir committed-information-rate: Specifies the committed information rate (CIR) in kbps.
cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The committedburst-size argument ranges from 4000 to 16000000, the default is 4000.
ebs excess-burst-size: Specifies excess burst size (EBS) in bytes. The excess-burst-size
argument ranges from 0 to 16000000, the default is 4000.
pir peak-information-rate: Specifies the peak information rate (PIR) in kbps.
green action: Specifies the action to be conducted for the traffic conforming to CIR. The action
argument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards
them to their destinations. The new-dscp argument is in the range 0 to 63.
By default, packets conforming to CIR are forwarded.
red action: Specifies the action to be conducted for the traffic conforms to neither CIR nor PIR.
The action argument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards
them to their destinations. The new-dscp argument is in the range 0 to 63.
By default, packets conforming to neither CIR nor PIR are dropped.
yellow action: Specifies the action to be conducted for the traffic conforms to PIR but does not
conform to CIR. The actionargument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards
them to their destinations. The new-dscp argument is in the range 0 to 63.
By default, packets conforming to PIR but not conforming to CIR are forwarded.
i think B is the correct Answer, Since the traffic is conforme to PIR
0
0
In this case it does not conform to CIR so it’s yellow ^^
0
0
B
In this example:
0 Gbps – 1 Gbps = green (CIR)
1 Gbps – 2 Gbps = yellow (PIR)
2 Gbps and more = red (drop)
0
0
