show commands on a real router

| If you have access to a real router could you help me find the correct answer to this CCNA study question? I need some help figuring out which show commands are available in user EXEC mode. I have tried searching Cisco’s site and have tried using a router simulator, but I still have a couple of questions. If you have access to a real router you could provide the definitive answers.
I would like to know what is the output of the "show ?" command in user EXEC mode, and also the results of trying "show interface serial 0", and "show ppp" in user EXEC mode. If the output is blank I would assume that it a legal command.
So far I found out from the Cisco documentation for IOS 12.2 that these commands are available in EXEC mode:
show aliases
show users
show version
These are privilege EXEC commands:
show arp
show running-config
First question: Is "show interface serial 0" a valid EXEC command, or is it privilege EXEC? I was confused because the documentation said show interfaces serial is
Privileged EXEC - but EXEC for frame-relay info?
Quote: ”To display information about a serial interface, use the show interfaces serial command in privileged EXEC mode. When using Frame Relay encapsulation, use the show interfaces serial command in EXEC mode to display information about the multicast data-lilnk connection identifier (DLCI), the DLCIs used on the interface, and the DLCI used for the Local Management Interface (LMI).”
Second question: is "show ppp" a valid user EXEC command? I did not find documentation on it except as show ppp multilink (EXEC), show ppp bap (privilege), and show ppp mppe (privilege).
Thanks. | |

| The user exec level usually accepts most basic troubleshooting commands. You can view the status of your interfaces, so you can use the "show interface serial0" command:
Router>sh int ser0
Serial0 is up, line protocol is up
Hardware is QUICC Serial
Internet address is 192.168.55.38/30
MTU 1500 bytes, BW 256 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 108/255
Encapsulation HDLC, loopback not set
Keepalive set (10 sec)
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue :0/40 (size/max)
5 minute input rate 109000 bits/sec, 75 packets/sec
5 minute output rate 2000 bits/sec, 4 packets/sec
14746795 packets input, 2398478357 bytes, 0 no buffer
Received 571261 broadcasts, 0 runts, 0 giants, 0 throttles
1386 input errors, 40 CRC, 55 frame, 0 overrun, 0 ignored, 1291 abort
5054187 packets output, 305700279 bytes, 0 underruns
0 output errors, 0 collisions, 803 interface resets
0 output buffer failures, 0 output buffers swapped out
40 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
But the frame relay troubleshooting commands are only accessible in the privileged mode.
The "show ppp" is a valid user exec command but in that form it is incomplete:
Router>sh ppp
% Incomplete command.
Router>sh ppp ?
bap BAP parameters and statistics
multilink Multilink PPP bundle information
queues PPP request queues
Remember though, that the available commands will vary according to version of code and what feature set you have got.
