Task 2: Week Six Discussion – Power over Ethernet

Power over Ethernet (PoE) has become an important feature for network switches especially when it comes to IP phone and wireless access point placement. In no less than 350 words, descibe the operation of when it comes to detecting a Powered Device (PD) and how much power it should supply. ALso list the PoE standards in your description.

Task 3: Week Five Discussion – Log message Severity Levels

Task 3: Week Five Discussion – Log message Severity Levels

Logging is an important feature in the Cisco IOS software. It assists network administrators in troubleshooting issues and display what the currect state of the network is. There are many logs that get generated but it can be hard to determine the importance of each message. Explain how the Cisco IOS software assigns severity levels to messages. What are these severity messages and how are they displayed? What do they mean? Explain these levels in no less than 350 words.

Lab 5: QoS-Classifying and Marking Traffic
Name: _____________________________________
 1. Build the following network in Cisco Packet Tracer.
g0/0/1
g0/0/0
 2. Configure the interfaces on the router as follows:
Router(config)#interface g0/0/0
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no shutdown
Router(config)#interface g0/0/1
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#no shutdown
 3. Configure the PCs as follows:
a. PC1: IP Address 192.168.1.5 subnet mask 255.255.255.0, gateway 192.168.1.1
b. PC2: IP Address 192.168.1.6 subnet mask 255.255.255.0, gateway 192.168.1.1
c. PC1: IP Address 192.168.2.5 subnet mask 255.255.255.0, gateway 192.168.2.1

Lab 5: QoS-Classifying and Marking Traffic
Classifying Traffic
 4. Here we will just classify traffic and not really apply any quality of service actions to it. We will
create a classification for any web traffic coming into R1 on interface g0/0/1. Type in the
following commands:
First we need to create the rule that specifies web traffic. We do this by creating an access list
looking for any traffic on port 80.
Router(config)#ip access-list extended WEB_BROWSING_ACL
Router(config-ext-nacl)#permit tcp any any eq 80
Next we create a class (I’ll call it WEB_BROWSING_CLASS) and have it match on the access
list I just created.
Router(config-ext-nacl)class-map WEB_BROWSING_CLASS
Router(config-cmap)#match access-group name WEB_BROWSING_ACL
Now create a policy (I’ll call it CLASSIFY_WEB) and have it use the class map I just created.
Router(config-cmap)#policy-map CLASSIFY_WEB
Router(config-pmap)#class WEB_BROWSING_CLASS
Now it must be applied to an interface, in this case we want to classify the traffic coming into
g0/0/1.
Router(config-pmap)#interface GigabitEthernet 0/1
Router(config-if)#service-policy input CLASSIFY_WEB
 5. Type in the following command:
Router#show policy-map interface g0/0/1
How many web packets show up in the class? __________________________

Lab 5: QoS-Classifying and Marking Traffic
 6. Now click on PC2, click on Desktop and select Traffic Generator. Set the following parameters
as shown in the screenshot below.
 7. Click on the Send button below just once. Type in the following command in the router again.
Router#show policy-map interface g0/0/1

Lab 5: QoS-Classifying and Marking Traffic
How many web packets show up in the class? __________________________
Marking Traffic
 8. Now we will give the packets from PC2 a higher priority than the packets coming from PC1. Type
in the following commands
First create the rule:
Router(config)#access-list 110 permit ip host 192.168.1.6 any
Then create the class called IMPORTANT and have it match on the rule we just created.
Router(config)#class-map match-all IMPORTANT
Router(config-cmap)# match access-group 110
The create a policy called SETDSCP and set any packets from the class IMPORTANT set to “ef”
which is a higher priority than the default packets usually set to 0.
Router(config-cmap)#policy-map SETDSCP
Router(config-pmap)#class IMPORTANT
Router(config-pmap-c)# set ip dscp ef
Now apply the policy to the interface g0/0/1 where PC2 is attached and on inbound traffic set
anything from PC2 to “ef”.
Router(config-pmap-c)# interface g0/0/1
Router(config-if)#service-policy input SETDSCP
Router(config-if)#end

Lab 5: QoS-Classifying and Marking Traffic
 9. Type in the following command:
Router#show policy-map interface g0/0/1
How many packets are marked with dscp ef? _________________________
 10. Now from PC1, ping PC3. Now run the command show policy-map interface g0/0/1. Did the
number of packets marked “ef” increase? ___________________ Paste your output below.
 11. Now from PC2, ping PC3. Now run the command show policy-map interface g0/0/1. Did the
number of packets marked “ef” increase? ___________________ Paste your output below.
End of Procedure
