Re: Cisco 3500 XL support spanning loopguard default command

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".

Re: Cisco 3500 XL support spanning loopguard default command

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,

Re: Cisco 3500 XL support spanning loopguard default command

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,

Re: Cisco 3500 XL support spanning loopguard default command

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

Re: Cisco 3500 XL support spanning loopguard default command

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.
