Shedding some light on a switch encapsulation problem

Tricon7

My "new" 2924 switches won't encapsulate; it's like the command doesn't exist. Not very good, if I'm wanting to prepare for my CCNA. Here are some commands and their outputs. Perhaps someone can help. Thanks.

Config t

Switch#config t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#

Interface fastethernet 0/1

Switch(config)#int fa 0/1
Switch(config-if)#

Switchport mode trunk

Switch(config)#int fa 0/1
Switch(config-if)#switchport mode trunk
^
% Invalid input detected at '^' marker.

Switch(config-if)#

Switchport trunk encapsulation

Switch(config-if)#switchport trunk encapsulation
^
% Invalid input detected at '^' marker.

Switch(config-if)#

Switchport ?

Switch(config-if)#switchport ?
access Set access mode characteristics of the interface
mode Set trunking mode of the interface
multi Set characteristics when in multi-VLAN mode

Switchport mode ?

Switch(config-if)#switchport mode ?
access Set trunking mode to ACCESS unconditionally
multi Set trunking mode to multi-VLAN mode

what version of the 2924 do you have? And what's the IOS version?

Check this page for more details:
http://www.cisco.com/en/US/docs/switches/lan/catalyst2900xl_3500xl/releasesa4/eesoftconfig/mascovr.html

Basically, there's about 4 "editions" of the 2900XL series that won't do trunking. For others, it could be just an IOS version you have to upgrade to.

You need an upgrade man. I'm running 12.1 on my 2924XL and the only wierd things I have found with that version is port security violation behavior.

I'm sorry to tell you, but you got screwed over...similar to my Cisco 2908XL, your switch already contains the latest IOS it will support (11.2 SA6), and none of the 11.x IOS will support trunking.

See this link to verify your next switch purchase, double check the model number, again, and double check it once again to make sure your new switch will support ver 12.0 IOS so that you can do trunking.

Well, I was already heading for that conclusion, so I'm not entirely shocked. Thanks for the info. It's not really a total loss, as I can always sell them back on eBay and get most/all of my money back. Still, I wasted a lot of time that I could have used in real-time practice. Live and learn (I knew I should have coughed up the extra money and gotten some 2950 switches!)

I like the line "Copyright (c) 1986-1902 by cisco Systems, Inc."

Guess it's not Y2K compliant.
