To change IP TOS value of a GRE tunnel
1. Click Interfaces under Configuration > Interface Configuration in the tree view.
2. In the Logical column, click the Logical Interface link of the item for which to change the
TOS. Example:
tun0c1.
3. Select a value from the TOS value drop-down window.
Click Apply.
On GRE tunnels, it is desirable to copy or specify the TOS bits when the router encapsulates
the packet. After you select the TOS value, intermediate routers between the tunnel
endpoints may take advantage of the QoS features and possibly improve the routing of
important packets. By default, the TOS bits are copied from the inner IP header to the
encapsulating IP header.
If the desired TOS value is not displayed in the drop-down window, select C
USTOM VALUE
from the menu.
Click Apply. An entry field appears.
4. (Optional) If you selected custom value from the TOS value drop-down window, enter a
value in the range of 0-255.
Click Apply.
