Chapter 12 Policy and Static Routes Table 89 Configuration > Network > Routing > Policy Route > Add/Edit (continued) LABEL Trunk Interface DSCP Marking DSCP Marking DESCRIPTION This field displays when you select Trunk in the Type field. Select a trunk group to have the UAG send the packets via the interfaces in the group. This field displays when you select Interface in the Type field. Select an interface to have the UAG send traffic that matches the policy route through the specified interface. Set how the UAG handles the DSCP value of the outgoing packets that match this route. Select one of the pre-defined DSCP values to apply or select User Define to specify another DSCP value. The "af" choices stand for Assured Forwarding. The number following the "af" identifies one of four classes and one of three drop preferences. See Assured Forwarding (AF) PHB for DiffServ on page 212 for more details. Select preserve to have the UAG keep the packets' original DSCP value. Select default to have the UAG set the DSCP value of the packets to 0. User-Defined Use this field to specify a custom DSCP value. DSCP Marking Address Translation Use this section to configure NAT for the policy route. Source Network Address Translation Select none to not use NAT for the route. Select outgoing-interface to use the IP address of the outgoing interface as the source IP address of the packets that matches this route. To use SNAT for a virtual interface that is in the same WAN trunk as the physical interface to which the virtual interface is bound, the virtual interface and physical interface must be in different subnets. Otherwise, select a pre-defined address (group) to use as the source IP address(es) of the packets that match this route. Use Create new Object if you need to configure a new address (group) to use as the source IP address(es) of the packets that match this route. Healthy Check Use this part of the screen to configure a route connectivity check and disable the policy if the interface is down. Disable policy route automatically while Interface link down This field displays when you select Interface or Trunk in the Type field. Select this to have the UAG automatically disable this policy route when the interface is down or disabled. Enable Connectivity Check This option is available when you select Interface or Gateway in the Type field. Select this to turn on the connection check. Check Method Select the method that the gateway allows. Select icmp to have the UAG regularly ping the gateway you specify to make sure it is still available. Check Period Check Timeout Check Fail Tolerance Check Port Select tcp to have the UAG regularly perform a TCP handshake with the gateway you specify to make sure it is still available. Enter the number of seconds between connection check attempts. Enter the number of seconds to wait for a response before the attempt is a failure. Enter the number of consecutive failures before the UAG stops routing through the gateway. This field only displays when you set the Check Method to tcp. Specify the port number to use for a TCP connectivity check. UAG Series User's Guide 210
