742 Appendix A: Answers to the "Do I Know This Already?" Quizzes and Q&A Sections
54
Name the command that lists all the SAP entries in a Cisco router.
show ipx servers. Many people remember that the command uses either the servers, or
server, or service, or sap keyword. The exam is likely to list those four keywords as the
four answers; spend a little time memorizing the commands summarized at the beginning
of each configuration section in most chapters of this book.
55
How many different values are possible for IPX network numbers?
2
32
, or around four billion. Networks 0 and FFFFFFFF are reserved. The size of the
network number is one big reason why there is no need for subnetting IPX networks.
56
Create a configuration enabling IPX on each interface, with RIP and SAP enabled on each
as well, for a 2501 (two serial, one Ethernet) router. Use networks 100, 200, and 300 for
interfaces S0, S1, and E0, respectively. Choose any node values.
ipx routing 0200.1111.1111
interface serial 0
ipx network 100
interface serial 1
ipx network 200
interface ethernet 0
ipx network 300
The node part of the address was supplied in the IPX routing command so that the IPX
addresses are easily recognizable on the serial interfaces. This helps troubleshooting
because it will be easier to remember the IPX addresses used when pinging.
57
In the previous question, what would be the IPX address of the serial 0 interface? If
another user wanted to know but did not have the enable password, what command(s)
might provide this IPX address?
100.0200.1111.1111
show ipx interface
If you left off the node parameter on the IPX routing command in the previous question,
the IPX address would have a node number equal to the MAC address used on the Ethernet
interface.
58
What show command lists the IPX address(es) of interfaces in a Cisco router?
show ipx interface. The other show commands list only the IPX network numbers, not
the entire IPX addresses.
