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

00000000 0000 00000000

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)
