How do I fix the following errors in the output after entering the configuration from a config file for my Cisco 3750v2's:

% Invalid input detected at '^' marker.

ALS2(config)#$
ALS2(config)#interface FastEthern
% Incomplete command.

The following is the output of the show run command on ALS2, but how do I get rid of this 1/0/1 in similar output like this interface FastEthernet1/0/1 on all four swithes because I'm getting interface FastEthernet2/0/1, interface FastEthernet3/0/1, and interface FastEthernet4/0/1 on the other three switches.

It looks like someone copied the config over from a different model switch. Anyway, just save the running config again (copy run start) and it will go away.
 
Misread your post. Is this supposed to be a stack? Are you using stack cables? How is this wired up?
 
The format is jacked up like the above poster said. Copying from a previous config has it messed up.
 
Also, if you are copying a config through the console connection, a large config file will overflow the buffers. If this happens, you will see messed up errors like that above exactly.

Copy and paste 2 pages at a time, should copy in without issue.

Thanks I didn't know this could be a problem, but how do I copy 2 pages at a time from a text file that doesn't seperate config files into pages.

Yes I copied the configs over from a different model switch, which was from a 3560v2 to a 3750v2. How is that a problem though because their both pretty much running 15.0(2)SE4 or 7 and the configs from the 3560v2 are most likely using legacy commands, since it was using 15.0(2)SE4. However, the difference between 15.0(2)SE4 on the 3560v2 and 15.0(2)SE7 on the 3750v2 shouldn't matter much unless I had started with 15.0(2)SE7 on the 3750v2 and was moving to the 3560v2 with 15.0(2)SE4 because the 3560v2 would be more likely to have to use legacy commands when stepping down from a 3750v2.

It's not just up to the OS. Different switch models number their interfaces differently. I.e. fa1/0 vs fa1/0/1. Therefore, your config will be different because the interface numbering is different.

As for my stack question, I meant are you using stacking cables on the back if the switches or are they running as standalone switches with just a power cords and Ethernet cables connected to each one?
You can read more about switch stack cabling here.

If your switches are not stacked but your interfaces numbers on one switch is 1/0/X and 2/0/X on another, then it means that they used to be a part of a switch stack. You'll have to erase the configuration and start from scratch (without getting messy with trying to undo it).

On your config: you have the VLANs configured but none of the interfaces are assigned to VLANs, so they'll default to VLAN 1. So it's basically behaving like an unmanaged switch right now. Also, you don't have any DHCP configured.

Okay, so your saying I need to fix the time and date. How do I do that though?

I recommend you read this first.

If you still have questions, you want to watch CCNA videos or buy a book. Cisco has a steep learning curve and requires more time to learn this stuff.

TO copy a page at a time, open in notepad (or favorite text editor), select the start of the first line, then hold shift and PageDown. That will select a full page. PgDn twice and you have two pages selected and can copy in. Once copied, start at the next line after the selected lines.
 
Good tip DermicSavage, will keep that in mind. To set the time and date you can use the clock set command. Type clock set ? to see the format it wants you to use. Might be better off just looking at the config file or a working switch and manually setting up the new switch to match the settings you need, looks like the interface names are not the same and that's what is messing you up. I am not sure if or what command to use to rename the interfaces though (only just started the class this week where I'm learning to configure IOS/cisco stuff).

YouTube has a ton of videos on networking and working with IOS. Check out this channel for some tutorial videos: https://www.youtube.com/channel/UCwjafl4RJa6st6caneVWHkQ
 
The errors are because you're trying to enter an interface thats not correct... your 'show inventory' will show that you have a sub slot 1 for that module and so therefore your interfaces are fa1/0/1-48 with your 4 gig trunking ports. Different models/designs will have different interface numbers based on its module slots etc. If you're looking to make general config changes to all 48 ports at once, you'll find the 'interface range fa1/0/1-48' command helpful.

I think this was my problem because the configs seem to be fine even though I didn't exactly do this though to fix the problem consider I still tried to copy it all in at one and then recopy and paste from the point it messed up and over flowed the buffers.

Thanks. This would have helped if I would have tried this before I fixed it another way, which was not the right way. However, I fixed it though.
 
Yeah, Cisco's can be picky on how quick you past stuff via console. I usually do it in chunks less than a page.
