2900/3500XL only has 12.0 IOS and can't proceed any further.  This feature is not supported in this series of switches.  There is no such thing as a "3550XL".

according to Cisco 3550 switch command referece  12.1(14) yes it is supported. The command was first introduced 12.1(9) EA1

Are you having issue?

Hi,

Thanks for your reply.

But I made correction. I would like to know for 3500 XL models. ( 24 port and 48 port)

Waiting for your kind reply.

Thanks,

Samir

HI Francisco

Here is the attached file.

Thanks,

on your switch i see 120-5.3. the spanning-tree loopguard command was introdcuced on 12.1(9) EA1. You gonna have to upgrade to minimum 12.1(9) EA1 to support the loopguard command.

Hi Francisco,

Thank you very much for your early reply.

But I don't think so Cisco 3500XL series support that software.

Waiting for your kind reply.

Thanks,

Samir

The 12.1(9) is a release for 3550 EMI & SMI including 2950.

As for your 3550XL,  see this for IOS code you're on. http://cisco.biz/en/US/docs/switches/lan/catalyst2900xl_3500xl/release12.0_5_wc_1_/cli/clicmds.html.

spanning-tree loopguard is not listed under the command reference guide.

Hi Francisco,

That means it doesn't support.

Samir

It is most definitely not supported on the 3500XL.  I went through this exercise awhile back.

correct.

some Cisco IOS commands are either undocumented or not available under specific IOS. Always check the IOS command reference guide.

Common sense should tell you it's a typo mistake.
