LABEL

DESCRIPTION

 

Gateway IP

Enter the IP address of the gateway. The gateway is an immediate neighbor of your

 

Address

switch that will forward the packet to the destination. The gateway must be a router on

 

 

the same segment as your switch.

 

 

 

 

Metric

The metric represents the “cost” of transmission for routing purposes. IP routing uses

 

 

hop count as the measurement of cost, with a minimum of 1 for directly connected

 

 

networks. Enter a number that approximates the cost for this link. The number need

 

 

not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good

 

 

number.

19.2 DiffServ

DiffServ is a class of service (CoS) model that marks packets so that they receive specific per- hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going.

Enable this feature in the DiffServ screen. Click IP Configuration > DiffServ to display the screen as shown.
