VCI
Range: 0 through 65535
The default is 35, which is a typical Ethernet assignment. Along
with VPI, VCI identifies the next destination of a cell as it moves
through a series of ATM switches on the way to its destination.
The service provider typically assigns VCI.
IP ADDRESS
Options: STATIC (F1), DHCP (F2)
• STATIC: This type of IP management means that the user has
a permanent IP address. For STATIC, enter the LOCAL IP; this
will be the value used during the test.
• DHCP: This refers to dynamic IP management. If selected,
enter the IP address for the destination.
Dynamic management provides a way for computers to obtain
protocol configuration parameters (like the local IP address)
dynamically from the network. In this case, the IP address is
not permanent to the terminal; instead, the terminal requests
an address from the server on the network. When selecting
DYNAMIC for IP ADDRESS, the module sends a request to
the server; the server responds and provides an IP address.
Upon selecting DYNAMIC, the LOCAL IP line disappears; the
network dynamically assigns an IP address.
LOCAL IP
Enter a local IP address of the circuit under test. For LLC-BRG
static mode and LLC-RTE, this is the local IP address used.
For LLC-BRG DHCP mode, there is no LOCAL IP mode since a
dynamically assigned local IP address is used.
DESTINATION IP
Enter the destination address of the device to be pinged. If ping-
ing a gateway, enter the gateway's address for the Destination
IP. Pinging the gateway verifies connectivity to the ISP.
GATEWAY
If required, enter a gateway address. A gateway is a device that
connects dissimilar networks and passes information between
them. In TCP/IP, the default gateway address is the address
where the Internet Protocol sends packets destined for remote
networks, unless a different route is configured. Since LLC-RTE
is a pure routed mode, there is no gateway setting. This setting
applies only to LLC-BRG mode.
