4. Select an entry and click the 

 button to remove the selected entry from the IP forwarding table.

5. Click the 

 button to create a new static route. For more information, see 

.

6. Click 

 (to allow) or 

(to deny) routing between VLANs.

Use the 

 screen to add a new destination subnet, subnet mask and gateway for routing packets to a 

defined destination. Use the screen when an existing destination subnet does not meet the needs of the 
network. To add a new static route:

1. Click the 

 button.

A new 

 screen displays enabling you to add a new destination subnet, subnet mask and 

gateway for routing packets to a defined destination.

2. In the 

 field, enter an IP address to route packets to a specific destination address.

3. Enter a subnet mask for the destination subnet in the 

 field. 

The Subnet Mask is the IP mask used to divide internet addresses into blocks known as subnets. A value 
of 255.255.255.0 support 256 IP addresses.

4. In the

field, enter the IP address of the gateway used to route the packets to the 

specified destination subnet. Do not set the gateway address to any VLAN interface used by the switch.

5. Refer to the 

 field for the current state of the requests made from applet. This field displays error 

messages if something goes wrong in the transaction between the applet and the switch.

The 

 is used for selecting the best available path. If there are multiple routes 

for a particular destination address, the packets are forwarded on the basis of the route 
metric. Routes with lower metric value are given higher preference.

A routing protocol uses the route metric to determine which routes to include in the routing 
table when it has two available routes to the same destination from a single routing protocol 
(static, RIP, OSPF etc). The router includes the route with the smallest metric because it 
considers this route to be the shortest (and therefore the best). Different routing protocols 
calculate their metric in different ways. RIP uses hops, OSPF uses bandwidth etc. Sample 
values: 0, 1, 10, 20… Currently all static and connected routes have a default metric of 0.

When IP Forwarding is enabled for the selected subnet, a green check displays in the Active 
column.
