3. Create the first time policy under Contract 1, for peak working hours.
4. Create the second time policy under Contract 1, for weekday evening hours.
5. Apply the default BWM Policy 3 to this contract. This BWM policy will be in effect at all other
times beyond the specifications of the two time policies.
6. Assign the contract to an ingress port on Alteon.
7. Apply and save the configuration.
Example
Egress Bandwidth Tuning for Lower Speed Networks
When an Alteon is connected to a router that feeds into lower speed networks, the egress traffic
from Alteon should be throttled down to prevent the packets from being dropped from the router as
it forwards traffic into the slower network.
For example, an Alteon may be connected to a router with high bandwidth of 1 Gbps. However, that
router may be connected into a Wide Area Network (WAN) using a T1 line (1.544 Mbps) or a T3 line
(44.736 Mbps). Any packets that exceed the capacity of the WAN are dropped.
Egress bandwidth tuning is only available on 10/100/1000Base-T ports. To tune down the egress
bandwidth to T3 speeds, enter the following commands:
>> # /cfg/bwm/cont 1/timepol 1
>> BW Contract 1 Time Policy 1# day weekday
Current Time Policy Day: everyday
Pending new Time Policy Day: weekday
>> BW Contract 1 Time Policy 1# from 7am
Current Time Policy from hour: 12am
Pending new Time Policy from hour: 7am
>> BW Contract 1 Time Policy 1# to 7pm
Current Time Policy to hour: 2am
Pending new Time Policy to hour: 7pm
>> BW Contract 1 Time Policy 1# policy 1
>> BW Contract 1 Time Policy 1# ena
Current status: disabled
New status: enabled
(Assign highest BWM policy to this
time policy)
>> # /cfg/bwm/cont 1/timepol 2/day weekday/from 7pm/to 11pm/policy 2/ena
>> # /cfg/bwm/cont 1/policy 3/ena
>> Main# /cfg/port 1
>> Port 1# cont 1
Current BW Contract: 256
New pending BW Contract: 1
>> # /cfg/port 1
>> Port 1# egbw 44M
>> Current port egress bandwidth: 0K
New pending port egress bandwidth: 44M
(Select the desired port)
(Change the egress bandwidth
to 44 Mbps)
