The factory default is for the DMM to run through a full set of diagnostics each time it is rebooted. By using the following command you can make the DMM bypass the diagnostics and boot up faster:

8260A> set device diagnostics disable

MAC address order

In general, Ethernet devices uses canonical address format, whereas token-ring devices use a non-canonical address format. However, DMM is shipped from the factory to display all the addresses in canonical format regardless of the type of originating station. For example, with canonical setting for DMM, if we display the current ARP table entries of DMM, the result will be as shown in Figure 26.

In this example 9.67.46.46 is an Ethernet attached station whereas 9.67.46.237, and 9.67.46.238 are both token-ring attached stations. As can be seen, all the addresses are shown in canonical format.

You may use the following command to set the non-canonical format to be used by DMM:

8260A> set device mac_addr_order noncanonical

After issuing the above command, the current ARP table will be displayed as shown in Figure 27.
