Since the Cisco 67x only has one physical port for the Ethernet port, the default value is always 0 as in eth0.
Use this command only when you have a serial connection with Cisco 67x. If you use this command when you are communicating over an Ethernet LAN, you will lose the connection to Cisco 67x. If you forget and issue this command over the LAN, you can reset Cisco 67x by switching the Cisco 67x OFF and then turning the power back ON.
The following example assigns the Ethernet interface an IP address.
set interface eth0 address 198.162.55.5

The following example sets the VCI address for the wan0-0 port to equal 1, which is in the valid range for VCI addresses.
set interface wan0-0 vci 1
The Cisco 67x has a total number of four VCs (wan0-1 through wan 0-3). Configure only the total number of actual VCs terminated to optimize the performance of the Cisco 67x. Close the wanx-x port before making any changes to the port.
The Cisco 67x supports user configuration of VPI/VCI address mapping. The Cisco 67x ships with one VC enabled. Its VPI/VCI address is 1/1. When changing the VPI/VCI address space mapping, it is important to understand that adding VPI space decreases VCI space. For example, if the VPI count is one, 255 possible VCI values are available for the single VPI. If the VPI count is eight, the number of possible VCI values is reduced to 31 VCIs for each of the eight VPIs.
When changing the VPI count values, you must ensure that VPI and VCI port assignments are consistent with the VPI count mode selected. For instance, when changing the VPI count from four to one, you must change the VPI port assignment to zero (0) on all wan0-x ports previously assigned to values other than 0, since 0 is the only valid VPI when the VPI count is 1.
The valid ranges for VPI and VCI addresses are shown in the following table:
| VPI <count> | VPI Range | VCI Range |
|---|---|---|
1 | 0 | 0..255 |
2 | 0..1 | 0..127 |
4 | 0..3 | 0..63 |
8 | 0..7 | 0..31 |

Exec and Enable
The following command displays the statistics for the Ethernet interface:
stats ip eth0
The following command enables MAC address dumping in bridging mode:
stats bridging eth0
The following command enables MAC address dumping on the wan0-o port:

To trace the routes that a data packet takes until it reaches its destination IP address. The traceroute command traces routes along the network, listing all hops and gateways, until it reaches the specified IP address.
traceroute ip-address [-m number-of-hops] [ -w wait-time
ip-address | Specifies the final destination IP address. |
-m number-of-hops | Sets the Max Time to Live by specifying the number of hops to the trace.Most systems use a default of 64 TTL. Please refer to the appropriate system documentation for your system's default. |
-w wait-time | Specifies the amount of time, in seconds, to wait for response. |
-p udp-port-number | Specifies the UDP port number on which to use the trace facility. |
Exec and Enable
The following command traces the route for IP address 208.192.56.1. The example uses all arguments and assigns a server from which to originate the command string.
traceroute 208.192.56.1 -m 64 -w 5 -p 198.162.2.1
To write configuration changes to NVRAM.
writeThis command has no arguments or keywords.
