Enable portfast and bpdu guard globally

Posted on 2011-04-25

I have 7 x cisco 3750 stackwise switches in a stack configuration.  If I globally enable portfast and bpduguard, will any ports that are trunking or in anyother config mode that doesn't support portfast then ignore that command, or will it change them?  Thanks.

    Accepted Solution

    The global command will apply that setting to the port if the port is not a trunk port.  What other modes did you have in mind?  you may want to specifically disable this feature on a port by port basis to be 100% sure.  The port config mode overrides the global config.

    Also to help out try enabling the timeout for when a switchport is put into errdisable mode due to this feature.

    CatSwitch-IOS(config)# errdisable recovery cause bpduguard

    CatSwitch-IOS(config)# errdisable recovery interval 400

    The timeout can be adjusted and is set in seconds.

    Let me know if there is anything else.
