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

(Netgear Switch) (Config)#interface 1/0/1

(Netgear Switch) (Interface 1/0/1)#service-policy in internet_access (Netgear Switch) (Interface 1/0/1)#exit

(Netgear Switch) (Config)#interface 1/0/2

(Netgear Switch) (Interface 1/0/2)#service-policy in internet_access (Netgear Switch) (Interface 1/0/2)#exit

(Netgear Switch) (Config)#interface 1/0/3

(Netgear Switch) (Interface 1/0/3)#service-policy in internet_access (Netgear Switch) (Interface 1/0/3)#exit

(Netgear Switch) (Config)#interface 1/0/4

(Netgear Switch) (Interface 1/0/4)#service-policy in internet_access (Netgear Switch) (Interface 1/0/4)#exit

Set the CoS queue configuration for the (presumed) egress inter- face 1/0/5 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-queue attribute. It is presumed that the switch will for- ward this traffic to interface 1/0/5 based on a normal destination address lookup for internet traffic.

(Netgear Switch) (Config)#interface 1/0/5

(Netgear Switch) (Interface 1/0/5)#cos-queue min-bandwidth 0 25 25 25 25 0 0 0 (Netgear Switch) (Interface 1/0/5)#exit

(Netgear Switch) (Config)#exit
