Need help configuring etherchannel on a 3512XL switch

Can anyone shed any light on this? I'm soo confused!

the switch is running:
Cisco Internetwork Operating System Software
IOS (tm) C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC17, RELEASE SOFTWA
RE (fc1)

I've already sucessfully configured an etherchannel pair on the 2950 I have on the other side of this link, but here's what I run into when I try to do the same on the 3512XL:
Crarion3512XL(config)#int ?
  FastEthernet       FastEthernet IEEE 802.3
  GigabitEthernet    GigabitEthernet IEEE 802.3z
  Multilink          Multilink-group interface
  Port-channel       Ethernet Channel of interfaces
  VLAN               Switch VLAN Virtual Interface
  Virtual-TokenRing  Virtual TokenRing

Crarion3512XL(config)#int Port-channel ?
  <0-2147483647>  Port-channel interface number

Crarion3512XL(config)#int Port-channel 1 ?
% Unrecognized command
Crarion3512XL(config)#int Port-channel 1
                          ^
% Invalid input detected at '^' marker.

Crarion3512XL(config)#

HUH? Is this a bug, or am I missing something here?

    I think it is a bug because I have a 2924 that does that. Try to create the etherchannel without a portchannel interface. Try going into interface config mode and doing

    channel-group 1 mode on

    or

    port group 1 ?
    There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1!

    OK, *whew* thanks. I'll try that. I was questioning my sanity there for a bit.

    The 2900's and 3500's don't support the channel-group command because they can't use PAgP

    If you use the port group commands to set up the older switch

    and then set the newer switch's interfaces to:

    channel-group 1 mode auto

    then they might work together

    let us know how you make out
