2.Create a DiffServ class of type “all” for each of the departments, and name them. Define the match criteria -- Source IP address -- for the new classes.

class-map match-all finance_dept match srcip 172.16.10.0 255.255.255.0 exit

class-map match-all marketing_dept match srcip 172.16.20.0 255.255.255.0 exit

class-map match-all test_dept

match srcip 172.16.30.0 255.255.255.0 exit

class-map match-all development_dept match srcip 172.16.40.0 255.255.255.0 exit

3.Create a DiffServ policy for inbound traffic named 'internet_access', adding the previously created department classes as instances within this policy.

This policy uses the assign-queue attribute to put each department's traffic on a different egress queue. This is how the DiffServ inbound policy connects to the CoS queue settings established below.

policy-map internet_access in class finance_dept

assign-queue 1 exit

class marketing_dept assign-queue 2

exit

class test_dept assign-queue 3

exit

class development_dept assign-queue 4

exit exit

4. Attach the defined policy to interfaces 0/1 through 0/4 in the inbound direction

interface 0/1

service-policy in internet_access exit

interface 0/2

service-policy in internet_access exit

interface 0/3

service-policy in internet_access exit

interface 0/4

service-policy in internet_access exit

5.Set the CoS queue configuration for the (presumed) egress interface 0/5 such that each of queues 1, 2, 3 and 4 get a minimum guaranteed bandwidth of 25%. All queues for this interface use weighted round robin scheduling by default. The DiffServ inbound policy designates that these queues are to be used for the departmental traffic through the assign-
