no ip sla enable reaction-alerts on Cisco Catalyst 3560 vs IOS 12.2(55)SE1 does not disable reaction alerts

Hi,

I am attempting to upgrade a Catalyst 3560 v2 Series PoE-48 from an older Catalyst 3560. I have upgraded the new Cat to IOS 12.2(55) and copied the running-config over.

When comparing the old running-config to the new running-config I discovered that

ip sla enable reaction-alerts

is turned on automatically. As this uses memory and could be a potential form of overhead as we don't use it, I would like to turn it off.

The command

no ip sla enable reaction-alerts

Has no effect: See here below. I have removed the MAC address and the standard texts from the show version.

Is this a bug or am I missing something in order to turn this unwanted (at the moment) functionality off.

Re: no ip sla enable reaction-alerts on Cisco Catalyst 3560 vs I

On Aug 6, 2010 another Cisco customer also noticed this behaviour, but his thread was on another topic so this message got missed by the Cisco Employee helping.

Re: Ciscoworks showing + and - when running a compliance check

Also the no ip sla enable reaction-alerts command is not removing this from the configuration.
