				User Interface Commands for the UltraNet Edge 3000
TANKIO	The TANKIO user interface provides information regarding the
	circuit across the WAN. For further information on the TANKIO user
	interface commands, refer to the TANKIO commands section in the
	UltraNet Edge Storage Router Command Reference. The following
	sections highlight the commands useful for troubleshooting.
tankio stats	This command displays the current status and statistics of the WAN.
	Example of tankio stats command screen display:
	# St Bus Vid InPackts InOctets RcvC RecvOOSq OutPckts
	OutOctts XmtC ReXmitCt
	1 Up 090 090 000001be 00000000 0000 00000003 000001c9
	00000000	0000	00000000
			0000e6a8
	00010528
	The status of the circuit is found in the St field. Up indicates that the
	circuit is established with the peer node. Down indicates that the
	circuit is not established with the peer node.
	1. If the circuit status is down, first check the physical interface to
	make sure the interface link is up. See either the “AMDENET
	10/100 WAN or Maintenance Interface” section or the “GNIC3
	Gigabit Ethernet WAN” section.
	2. If the interface link is up, check the IP addresses, the subnet mask,
	the default gateway, and the static routes. These all need to be
	correct for the circuit to come up.
ARP	The ARP user interface provides information about devices
	physically attached to all of the Ethernet interfaces. For further
	information on the ARP user interface commands, refer to the ARP
	commands section in the UltraNet Edge Storage Router Command
	Reference. The following sections highlight the commands useful for
	troubleshooting.
arp tbl	This command displays the IP address of the Ethernet maintenance
	interface, the WAN Ethernet interface, and the devices that are
	attached to them.
	tm.0x10> arp
	arp1.0x10> tbl
	Example of the arp tbl command screen display:
	instance 1 (ethernet1) (10/100 Ethernet maintenance interface)
