√: Supported,

*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).

Precautions

When the operating configurations are modified, interfaces using the modified list will restart.

￿	-queuen	_bandwidthThis setting<Rate>is supported(nisanumberonly infromthe -1bandwidth-16)	queue mode;
		it is invalid in -priority or -round_robinmode. 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
		1 or greater in -queue8_bandwidthat all times because RIP,
		ARP, and other frames implement queueing at queue8. If a
		packet for control 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.
