Configure the CoS WRED precedence settings for dropping
packets
If you use the Weighted Random Early Detection (WRED) method as the queue depth
management method (see Configure CoS queue settings for an interface on page 460),
you can configure the precedence settings for dropping packets if a queue is full. These
settings apply to a selected interface and a selected queue. You can configure different
setting for each queue and for each precedence level on one interface.
To configure CoS WRED precedence settings for dropping packets:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The System Information page displays.
5. Select QoS > CoS> Advanced > CoS Queue Drop Precedence Configuration.
The CoS Queue Drop Precedence Configuration page displays.
6. From the Interface menu, select an interface.
7. From the Queue ID menu, select a queue from 0 to 7.
8. From the Drop Precedence Level menu, select the drop precedence levels from 1
to 4.
Packets to which level 1 applies are the most likely to be dropped. Packets to which
level 4 applies are the least likely to be dropped.
The following table shows the default values for each drop precedence level. You
can modify these settings.
