| Configuring the WSM using Device Manager |
|
Whenever the soft limit for the traffic policy type of service is exceeded, optional packet coloring can be done to allow downstream routers to use diff-serv mechanisms (that is, writing the Type-Of-Service (TOS) byte of the IP header) to delay or discard these out-of-profile frames. Frames that are not out-of-profile are marked with a different, higher priority value. This feature can be enabled or disabled on a per-contract basis, by enabling/disabling overwriting IP TOS on the Traffic Contracts tab. The actual values used by the WSM for overwriting TOS values (depending on whether traffic is over or under the soft TOS limit) are set on the Traffic Policies tab. The values allowed are 0-255. Typically, the values specified should match the appropriate diff-serv specification but could be different, depending on the customer environment.
