IOS "interface" command

Greetings. I am attempting to configure my Cisco 831 router to VPN connect to another server. I have been given IOS commands in order to create the connection, however there is one command that does not seem to be valid with my router and I was hoping someone could help me interpret it. The command is:
interface fa0/0
the comment beside this command says: "Assumed as inside interface" and this appears later as:
interface fa0/1
with the description "Assumed as Public Internet interface"
however, when I look at the available commands in interface mode, none resemble "fa0", here are the commands for interface:
router(config)#interface ?
Async Async interface
BVI Bridge-Group Virtual Interface
CDMA-Ix CDMA Ix interface
CTunnel CTunnel interface
Dialer Dialer interface
Ethernet IEEE 802.3
FastEthernet FastEthernet IEEE 802.3
Group-Async Async Group interface
Lex Lex interface
Loopback Loopback interface
MFR Multilink Frame Relay bundle interface
Multilink Multilink-group interface
Null Null interface
Tunnel Tunnel interface
Vif PGM Multicast Host interface
Virtual-PPP Virtual PPP interface
Virtual-Template Virtual Template interface
Virtual-TokenRing Virtual TokenRing
range interface range command
any ideas?

Paresh, thanks, however it seems "0" is an invalid fastEthernet choice (even though typing "?" says:
<0-4> FastEthernet interface number
Why is 0 invalid?
Also, the command I was told to use is the following:
interface fa0/1 # Assumed as Public Internet interface
ip address ##.##.###.### 255.255.255.x #Customer public interface
I removed the ip address numbers in this post for my own security, however the .x was exactly as the instructions said to use. I replaced this with 255.255.255.0 (as that is my subnet mask, and that's what I figured they were asking for), however I get the following message:
IP addresses may not be configured on L2 links.
what does that mean? (and thanks again for the help).

Passive interface command on RIP

Hi all,
This command below
passive-interface command give additional information to RIP, that it can't send updates via this particular interface ---
As per my understanding is this if we have 2 routers that are directly connected with each other and we enable this command on the interface of one of
routers then that router will not send any RIP updates to other router right?
secondly if these 2 routers are point to point connection we can ping directly conencted interfaces IP of routers because they are directly connected even though there is no routing protocol running between these two right?
3rd thing when i run sh ip protocols on one of router it shows
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 1 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Redistributing: rip
Default version control: send version 2, receive version 2
    Interface             Send Recv Triggered RIP Key-chain
    FastEthernet0/0       2     2
Automatic network summarization is in effect
Maximum path: 4
Routing for Networks:
    192.168.4.0
Routing Information Sources:
    Gateway         Distance      Last Update
    192.168.4.2          120      00:23:38 ****************************************************
here last update time keeps on incrementing but sh ip route does not show now that rip is running.
so this line means
Invalid after 180 seconds, hold down 180, flushed after 240
that after 240 secs router will flush the rip routes fron the routing table right?
but sh ip protocol will always show rip as routing protocol as we have config the rip and last update time will keep on incrementing right?
thanks

Hi Mahesh,
From the config guide:
To control the set of interfaces with which you want to exchange routing updates, you can disable the sending of routing updates on specified interfaces by configuring the
passive-interface
here is the link:
http://www.cisco.com/en/US/docs/ios/12_0/np1/configuration/guide/1crip.html
Correct, you do not need a routing protocol. The interfaces are directly connected. Now, if for example you add a loopback address to each router, you need a routing protocol or static router to reach the opposite router's loopback address.
The reason the interfaces/IPs do not show up in the RIP routing table is because they are directly connected and directly connected routes have a lower admin distance (1) which is preferred over rip which is 120.

VLAN Interface Command

Ok, I thought I had the reason for the VLAN interface command down. I thought it was either used for switch management or routing between VLANS? However, now I realized that some communication wont work with out this command which doesnt make sense. If I have a VLAN, then the switch will only switch packets to ports on the same VLAN. The only way, communication would work between VLANS is if I either enabled routing between VLANs with the VLAN Interface command, connected the switch to another multi-layer switch that did do routing between VLANS, or connected the switch to a router which routed between the VLANs.
However, I just got this new 3550 switch in, configured the correct ports with the assigned VLANs, and the only way my cisco ip phone would work is if the VLAN Interface for my voice-ip VLAN was configured. The 3550 is connected to a 4507. Now, can someone tell my why this is? You shouldnt have to configure the VLAN Interface, right?(unless I wanted to route between VLANs, which could be done by the 4507)

Sounds to me like you either dont have the dot1q trunk interface between your 4506 and 3550 working properly, or your 3550 is running the enhanced image which allows routing.
It would be nice to see your config on both the 3550 and the 4500 to determine the reason. Just a stab at how it should be configured is that on your 4506, you have it running VTP server or transparent with the defined Data and Voice Vlan's. You have a port configured for trunking (which connects to the 3550). On your 3550, you have configured it as a vtp client or transparent and have verified that it has received (or if transparent VTP you have configured) the appropriate VLAN's. You than specified "interface VLAN #" or whatever number for switch management and configured the port that connects to the 4500 as a trunk. Your port connected to the port has the auxillary or voice vlan configured. If this is how your equipment is configured and it still does not work, than look for the line "ip routing" in your 3550 and negate it with "no ip routing".
If still no worky worky, post your config.
Cheers,

I can send multiline interface commands but not data commands

hi
i am using a gpib controller.I cannot seem to find a way to switch between multiline commads and data commands.the key is the ATN bit as to send a DAB command the atn bit must be low. I cannot make the controller distinguish when a command is a adta command and not a multiline command,

sorry bit i did not know i could answer you directly.
i am using the measurement computing gpib controller cb7210.2 which is nearly ni compatabile.i am interfacing it with a microcontroller connected to the pc.Then i am trying to use a monitor program that is embedded in the microcontroller to perform remote access of instruments.i am using assembly. i have managed to communicate with the instrument.now the problem is that i cannot make the distinction between data commands and interface commands.for eg if i send 3Fh and atn happens to be 1 this is interpreted as UNL if atn is 0 then it is interpreted as data command.i need to be able to have control of the atn bit so that i can send either at will. so to problem is how to control the atn bit.
thanks

Global vs interface command on switch

Hello,
If I have a command globally which applies on all switch ports but then I want to configure one port with a different command not apply the global command on the switch. When i configure that port will it take effect the new command configure for that port and disregard the global command that was apply on all ports or the global command still take effect and interface command not take effect?

Some of the most common commands that are used on a per-interface level (which overrides the global commands) are:
1. STP;
2. UDLD;
3. PoE control;
4. Auto Switch Port macro (ASP)

CBWFQ: Question about the output of "show policy-map interface" command

Hi everyone,
I have a question about the output of "show policy-map interface" command.
The following is the output of this command and lower side of the output shows
(total queued/total drops/no-buffer drops) 0/342/0
If the packets drop occur due to the situation of no enough buffer,
"no-buffer drops" counted up. But "no-buffer drops" has not been counted up.
The "no-buffer drops" is 0 (zero) but "total drops" are counted as 342.
I guess there are other factors except "no-buffer drops" to add "total drops".
But I can not find any information about "other factors".
So I would like to know the "other factors" added to "total drops".

Interface & command consistency !?!

I am dismayed that the commands, interface, menu item location etc are so drastically different for each application. It is as if there are four different companies within Adobe, thus the simple commands like <ctrl> F does not have the same function in Illustrator as it does in InDesign. <ctrl> R in Acrobat is different in Illustrator etc etc .... Geewiz -- its frustrating! One of Adobes big pronouncements for the CS suite was the common interface from application to application within the CS suites ,,,,, uh someone screwed up in the kitchen because these Applications interfaces are obviously politically motivated and managed, with each enclave within Adobe being arrogantly possessive their own interface hierarchy and short cut functionality. Adobe upper management must take hold of these little enclaves of selfish power struggles and mandate a common interface/function/menu interface to live up to the marketing claim that the user will enjoy a consistent work environment. Really folks get it together, stop the power struggle and get over yourselves, and give the consumers/user/buyer what you promised. I dont expect anything to change within Adobe CS anytime soon, because the business culture therein is obviously stagnated and combative which will take years to resolve, unless there is courageous leadership at the top that abolishes the fortress mentality that permeates the product development cycle. Another thing I don't get is why,, when I open a file, why can't the save command default to the directory that I opened the file in. I end up saving in the wrong directory so many times because Adobe programs seem fixated on the last directory I saved to, which obviously a history lesson, and not the current folder/reality that is now my new focus and workflow. Thanks to all that have taken the time to let me vent. May your day unfold with new adventures.

EEM TCL for interface commands

I am working on a script that will make interface changes. I am trying to do the following:
1) save the output from the following command: #show cdp nei detail | i Interface
2) this will most likely give a list of interfaces some of which will be repeated. If the interface is listed more than once then i would like to remove the
    repeated interface. (note i am not concerned about the outgoing interface)
3)using the above information i would then like to make configuration to the interfaces with the following commands
     #config t
     #interface $intf
     #no mls qos vlan-based
     #mls qos trust dscp
i have started this script (please see attached file) and would really appreciate some assistance especially with how to eliminate multiple instances of the same interface.
thanks!!

I am having issues running scripts on my 3750x. One of the few commands i am getting to work is the
router(tcl)#puts "testing this command"
most all other commands are not working for example: ios_config, set
I am attaching a file with more details. Any help would be greatly appreciated!

Help sending multiline interface commands

Hello,
I have an instrument that is controlled by its own software on a PC that it is connected to with GPIB and RS232. I would like to write a labview program that emulates what the software does. I ran the GPIB analyzer during the initialization of the machine and captured this:
I want to send these 6 commands in LabView so I have a little vi that initializes the machine. I looked at this thread and tried to follow the advice given there. I need to send the string @?#yI followed by a line feed. I'm very new to LabView so I downloaded the example GPIB read/write and tried to make the changes suggested. Here is a screenshot of my attempt:
I'm sure this has many mistakes, can someone point them out to me? When I run it it either a) does nothing or b) gives me an error saying "the interface associated with this session is not the controller in charge".
Also, how can I send the "line feed" character? The manual for the instrument (attached, check page 63) says statements must be followed by a PRINT statement which is the line feed character according to the GPIB analyzer output ("a" in the sixth line).
Thanks!!!

Thanks for the advice Dennis. This is what I ended up with:
The VISA read sends the 4 green commands (TA0, UNL, LA3, SC25) by itself and the "I\n" in the buffer sends the data.
Now I am trying to get information back from the instrument. This screenshot is what the software is doing (and I want to replicate). In the red square are the commands I want VISA read to send. The instrument sends "60." back.
Basically, I want to have listener address 0 (LA0), talker address 3 (TA3) and secondary address 13.
Here's what I tried:
You can ignore the stuff at the begining and see that for the VISA read I set the VISA resource name as GPIB::0::13::INSTR. However that created this result:
There is a big mess of green commands. I need LA0 and TA3. In this case I got LA0 but TA0 instead of TA3. This was the error I got when I ran it:
So then I tried using the same block diagram but with the address GPIB::0::13::INSTR for the VISA resource name input on the VISA read. This time this is what happened:
This time I got LA3 not LA0 and the TA was not set at all. This was the error when I ran it:
Do you have any ideas on how to get this to work properly and what I am doing wrong?
Thanks!

IOS XR Command authorization with ACS server

We have a newly implemented ASR 9010 and are trying to figure out how to best configure it with TACACS, as it is slightly different than IOS.
In ACS, we have two groups: Group 1 and Group 2
Group 1 allows full access in the shell command authorization set.
Group 2 allows limited access in the shell command set (basically just show commands).
Both groups can login fine (aaa authentication login default group <groupname> local)
Group 1 has full access to everything (group I am in).
Group 2 has NO access to anything (can't even perform show commands).
Group 2 CAN access other IOS devices and can perform the various show commands.
With regards to our authorization commands, we currently have it configured as:
aaa authorization commands default group <groupname> local
Why is it working for the one group, but not the other? I've read how IOS XR uses task Ids and other various things that I'm unfamiliar with. I'm mainly curious if I have to use those, if the authorized commands are configured in ACS.
Thanks!
Kyle

dont have enough info to give you a full conclusive answer Kyle, but some suspicions.
Task group not set right?
Command groups not defined properly in tacacs for command author.
if you only want show access, you can just use the task groups in XR with a read permission on any command for instance. no direct need to send every command down to tacacs (hate that slowness )

Catalyst 4500 IOS to IOS XE command compatibility check?

Good Day.
I will be performing 4500 non-E chassis to 4500E chassis upgrade this week.
non-E chassis has IOS 12.2 running on it while 4500E will have IOS-XE 3.2.5SG code running. Is there any website where I can paste the IOS configuration to see if they are compatible on IOS XE code?
Thank you, sir.

There's no website or tool that I'm aware of to do such a pre-upgrade check for IOS to IOS-XE. That said, I've done several without issue. Just about all old commands carry forward.
One thing indirectly command-related is to make sure you have the same license level on the new switch (i.e. lanbase, ipbase or ipservices). If your new switch has a lower license level and you were using features that require the higher license level on the old switch, those commands won't be parsed on the new one because the features aren't available without the necessary license.
To verify, you should connect to the physical console port and log the output to a file while the system loads. Any commands that aren't parsed or have been deprecated will be logged as exceptions during the boot process. You can do this using the old switch configuration file loaded onto the new switch in advance of the actual cutover and resolve any issues ahead of time.

MARS - IOS interface up down, AD securuty entries

Our MARS appliance is running V4.2.1. We have about 40 or 50 IOS switches sending their entries to it. We see interface up and down transitions all the time as expected.
It seems that for many of the entries in MARS, the interesting data, such as the actual port number that went up or down, is nowhere to be found. Am I simply drilling wrong?
We have the same problem with Windows Active Directory security entries - we can see user account changes, but not who made them or which account was changed.

Seymour,
We see similar events on our MARS appliance too. We have nearly 300 switches logging to it now so you can imagine the up/down alerts that we have generated! You are correct that MARS does not provide complete information in the incident view. You are doing nothing incorrect. Keep in mind that the MARS appliance is aggregating a massive amount of security/system data and needs to normalize it to data fields that are most important when it comes to attack information. To view full messages keep in mind that you can view the "Raw Data" directly from the incident screen. In the case of interface up/down messages this would show you the exact port (it's found directly next to the "Reporting Device" name). Keep in mind that Cisco now has enchanced notifications using XML. This exported data contains the raw message that could be included as part of a notification like this:
