Use the address display <ADDR> <MASK>command to display a range of
addresses using a net mask. This is helpful when determining the status
associated with stations containing the same make of Ethernet network
interface cards. For example, to see all addresses that begin with
02:04:06, you would enter:
FN100 > address display 02:04:06:00:00:00 ff:ff:ff:00:00:00
LCM displays:
Address Type Port Sw#
02:04:06:03:2a:43 Learned 5 2
02:04:06:00:2a:67 Learned 4 2
02:04:06:a3:70:2b Learned 6 2
You can also use the address display <SW#> parameter to display address
information for a particular virtual switch.
LCM allows you to display MAC addresses in two formats:
• Little-endian (default)
Little-endian is a method of storing or transmitting data in which the
least significant bit of each byte is presented first. This is used in
Ethernet networks.
• Big-endian
Big-endian is a method of storing or transmitting data in which the
most significant bit of each byte is presented first. Use the big option
to display MAC addresses in big-endian format.
Big-endian format separates the bytes with spaces rather than colons.
You can also enter MAC addresses in big-endian format by using
spaces rather than colons. This option is helpful if your network
includes Token Ring or FDDI along with Ethernet.
Use the
ipaddr command to display the IP addresses, subnet masks, and
MAC addresses of all FN100 ports.
