EPON QoS commands
bandwidth-downstream
Use bandwidth-downstream to configure the downlink bandwidth limits on an ONU interface or RONU interface.
Use undo bandwidth-downstream to restore the default maximum downlink bandwidth or default maximum downlink burst buffer on an ONU interface or RONU interface.
Syntax
bandwidth-downstream { max-bandwidth bandwidth | max-burstsize burstsize } *
undo bandwidth-downstream { max-bandwidth | max-burstsize } *
Default
The maximum downlink bandwidth is 999994 Kbps (9999940 Kbps for 10G-EPON cards), and the maximum downlink burst buffer is 4194240 bytes on an ONU interface or RONU interface.

Parameters
max-bandwidth bandwidth: Specifies the maximum downlink bandwidth in the range of 0 to 999994 Kbps. For 10G-EPON cards, the value range is 0 to 9999940.
max-burstsize burstsize: Specifies the maximum downlink burst buffer in the range of 0 to 4194240 bytes.
Usage guidelines
For the downlink bandwidth limits to take effect, you must enable the downlink bandwidth allocation policy. The downlink bandwidth limits take effect only on known unicast packets.
Examples
# Set the maximum downlink bandwidth to 888 Kbps and the maximum downlink burst buffer to 999 bytes on ONU 1/0/1:1.
<Sysname> system-view
[Sysname] interface onu 1/0/1:1

undo onu upstream-sla maximum-bandwidth [ slot slot-number ]
In IRF mode:
onu upstream-sla maximum-bandwidth [ chassis chassis-number slot slot-number ] percent bandwidth-percent
undo onu upstream-sla maximum-bandwidth [ chassis chassis-number slot slot-number ]
Default

Parameters
percent bandwidth-percent: Specifies the maximum uplink bandwidth in percentage of the total uplink bandwidth, in the range of 1 to 100.
slot slot-number: Specifies a card by its slot number. If you do not specify a slot, this command applies to all cards. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a slot, this command applies to all cards. (In IRF mode.)
Usage guidelines
The actual maximum uplink default for ONU interfaces is calculated as follows after this command is executed:
· On a 1G-EPON card, the maximum uplink bandwidth of each ONU interface is 1 Gbps × bandwidth-percent. If the result exceeds 950 Mbps, the actual maximum uplink bandwidth is 950 Mbps.
· On a 10G-EPON card, the following rules apply:
¡ When 1G ONUs or 10G/1G ONUs are used, the maximum uplink bandwidth of each ONU interface is 1 Gbps × bandwidth-percent. If the result exceeds 950 Mbps, the actual maximum uplink bandwidth is 950 Mbps.
¡ When 10G/10G ONUs are used, the maximum uplink bandwidth of each ONU interface is 10 Gbps × bandwidth-percent. If the result exceeds 9500 Mbps, the actual maximum uplink bandwidth is 9500 Mbps.
This command takes effect globally. When both this command and the upstream-sla maximum-bandwidth max-value are executed, the upstream-sla maximum-bandwidth command takes effect on ONU interfaces where it is executed.
If you use this command without specifying any slot to configure the default maximum uplink bandwidth for ONU interfaces on all cards, you cannot use this command to configure the default maximum uplink bandwidth for the specified card, and vice versa. To modify the current configuration, first remove it. (In standalone mode.)
If you use this command without specifying any card to configure the default maximum uplink bandwidth for ONU interfaces on all cards, you cannot use this command to configure the default maximum uplink bandwidth for the specified card, and vice versa. To modify the current configuration, first remove it. (In IRF mode.)
