POLICY ROUTE COMMANDS
Policy Based routing is a method used by the Switch to give specified devices a cleaner path to the Internet. Used in
conjunction with the Access Profile feature, the Switch will identify traffic originating from a specified IP address and
forward it on to a next hop router that has a less congested connection to the Internet than the normal routing scheme of
your network.
The steps needed to set up policy-based routing on the switch are as follows:
•
Create an access profile using the
create access_profile
command which specifies information that will identify
the device to be given a policy route.
•
Modify the rule regarding this access profile using the
config access_profile
command. (Remember not to add
the deny parameter to this rule, or packets will be dropped and the policy route will not take effect.)
•
Name the policy route to be used by configuring the
create policy_route
command.
•
Bind the access profile (profile_id) and its rule (access_id) to this policy route using the
config policy_route
command. This command must also to be used to add the next hop IP address of the device that will be
connected directly to the gateway router. When the time is ready to deploy the policy route, the administrator
must enable this function here as well (state [enable | disable
])
.
Once completed, the Switch will identify the device to be given a policy route using the access profile function, recognize
that is has a Policy Based route, and then forward the information on to the specified next hop router, that will, in turn,
relay packets to the gateway router. Thus, the new, cleaner path to the Internet has been formed.
The Policy Route commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in
the following table.
