5. If addition/deletion/change in the parameters is executed in the qos-interface
(QoS interface information) in the Ethernet (NE100-8TB), communication in all of
thelinesinthesameNIFistemporarilydisabled.
6. With the interface that has used this command to set the group band control, the
group band control function can be executed only when the output priority has
been determined using the output priority designation in the flow control. If the
DSCP rewriting has been designated in the flow control or if the output priority
has been determined by the input packet DSCP value designation, the group
band control function cannot be executed. Table 1-80 shows the relationship
between the group band control and the flow control in priority determination.
7. When setting the group band control, the following restrictions shall apply:
It is necessary to set the control to a physical line in which no VLAN line has been
set.
When setting the group number three and higher, set the control only to the line
with line number zero. If the group number three or higher has been set, only the
line number zero will be able to communicate.
8. When setting the band control (traffic designation) in the VLAN line, the following
restrictions shall apply:
It is necessary that no transmission control other than the complete priority
control be set to a physical line on the VLAN line.
When setting a VLAN line greater than three lines to an interface in which the
band control (traffic designation) in the VLAN line has been set, choose only the
linewiththelinenumberzero.IfaVLANlinegreaterthanthreelineshasbeen
set, only the line with the line number zero is able to communicate.
9. It may not be possible to guarantee the specified bandwidth if bandwidth control
(traffic specified) or group bandwidth control is specified in Gigabit Ethernet and
the flow control function is enabled.
