ProSAFE 10-Gigabit Smart Managed Switch XS728T and XS748T User Manual
• Committed Burst Size. Enter the committed burst size that is applied to conforming
packets by specifying an integer from 3000 to 19173960. The committed burst size is
the maximum amount of traffic that is allowed in one burst (in bytes).
Note: The switch uses the token bucket algorithm, in which the committed
rate is the rate at which the bucket is filled, and the committed burst
size is the size of the bucket. This means that the committed burst size
is the maximum size of a burst that the switch can send.
13. Select the conforming and violating actions.
The Conform Action section and Violate Action section list the actions to be taken on
conforming packets according to the policing metrics. By default, both conforming
packets and violating packets are sent.
In both the Conform Action section and the Violate Action section, select one of the
following actions:
• Send. Packets are forwarded unmodified. This is the default conforming action and
the default violating action.
• Drop. Packets are dropped. This action can apply to a conforming action and to a
violating action.
• Mark CoS. Packets are marked by DiffServ with the specified CoS value before being
forwarded. This selection requires that the Mark CoS field is set. You must select a
CoS value from 0 to 7 from the menu. This action can apply only to a conforming
action.
• Mark IP DSCP. Packets are marked by DiffServ with the specified DSCP value before
being forwarded. This selection requires that the DSCP field is set. You must select a
DSCP code from the menu. If you select Other from the menu, you can enter an IP
DSCP value from 0 to 63. The DSCP value is defined as the high-order 6 bits of the
Service Type octet in the IP header. This action can apply only to a conforming action.
14. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.

2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Change the Default IP Address of the
