Hitachi Gigabit Router GR2000 Series Enhanced Version Configuration Commands, Vol. 2

Ver. 07-02
Precautions
When the operating configurations are modified, interfaces using the modified list
will restart.
This setting is supported only in the -bandwidth queue mode;
it is invalid in -priority or -
round_robin mode. Bandwidth
allocation is determined by the line rate; set this as a
percentage figure. Limit the value for total bandwidth to
100 or
less and indicate at least one queue within the
-
queue1_bandwidth-queue8_bandwidth setting. Enter a value of
1orgreaterin-
queue8_bandwidth at all times because RIP,
ARP, and other frames implement queueing at
queue8.Ifa
packet for control is not allotted to the transmitting queue
band, the packet for control at congestion of output lines may
not be transmitted from this device, making the
communication impossible due to breakage of the session.
Table 1-70 shows categories of the control packets produced in
this device.

*1: Does not check configurations. Will operate system on the default value (priority mode).
*2: Runs ATM QoS. The transmission control is performed by the traffic types of CBR, VBR, ABR, and UBR.
*3: When bod option is specified to PPP information or when IPX routing interface or bridge interface is specified to
PPP’s interface, processed by default (priority) value. If the maximum queue number has not been set or if an
ineffective value has been set, the number is automatically set at 8.
*4: This NIF supports the functions described in the media and layer 2 protocol item.
*5: In the minimum band guarantee and band control (traffic designation), the router does not operate in the specified
band when the full-duplex setting of 10BASE-T/100BASE-TX is changed to half-duplex setting (including automatic
negotiation).
