2. Enable BWM.
Note: If you purchased the Bandwidth Management option, be sure to enable it by typing
/oper/swkey
and entering the license string. For more information, see Using Bandwidth
Management, page 761
.
3. Select a bandwidth policy. Each policy must have a unique number from 1 to 64.
4. Set the hard, soft, and reserved rate limits for the policy, in Mbps.
Typically, charges are applied for burst rates between the soft and hard limit. Each limit must be
set between 64K and 1000M.
Note: For rates less than 1 Mbps, append a k suffix to the number.
5. Optionally, set the Type-Of-Service (TOS) byte value, between 0 and 255, for the policy
underlimit and overlimit.
There are two parameters for specifying the TOS bits: underlimit (
utos
) and overlimit (
otos
).
These TOS values are used to overwrite the TOS values of IP packets if the traffic for a contract
is under or over the soft limit, respectively. These values only have significance to a contract if
TOS overwrite is enabled in the Bandwidth Management Contract menu (
/cfg/bwm/cont <x>
/wtos ena
).
Note: You should use care when selecting the TOS values because of their greater impact on
the downstream routers.
6. Set the buffer limit for the policy. Set a value between 8192 and 128000 bytes. The buffer depth
for a BWM contract should be set to a multiple of the packet size.
Note: The total buffer limit for the Bandwidth Management policy is 128K.
