Hi,
The BPDU skew detection feature is not supported in Catalyst switches running Cisco IOS system software.
Note: The BPDU skew detection feature was introduced in CatOS version 6.2.1 of the Catalyst software for Catalyst 4000 and Catalyst 5000 platforms and in version 6.2.2 for the Catalyst 6000 platform.
