I am remotely monitoring a Cisco 2950 switch.  I want to use snmpv3, and I'm configuring the following:

ip access-list standard 1
 permit 172.18.102.22

!
snmp-server group SNMP_RO_GROUP v3 auth read SNMP_VIEW_RO access 1
snmp-server view SNMP_VIEW_RO internet included
snmp-server user SNMP_RO_USER SNMP_RO_GROUP v3 auth sha password

On this last line above, I get the following message:

Adding an snmpv3 user could cause a bootup delay,
do you wish to continue? (y/n)[confirm]

Has anyone experience this before?  All other devices I am monitoring are new and I didn't have this problem configuring snmpv3.  I don't want to hit yes above if this causes any type of boot delay.  I don't have another 2950 handy to test with.  Has anyone else every came across this?  Does it really cause bootup delay?

I think it is the common warning from 2950.

That is due to an enhanced security and encrypting using SNMPv3 user authentication.

There shouldn't be a significant delay and also you don't need to reboot the switch to have the change to be in effect.

Please look at this link.

yeah, seems like a common warning, I get it on some of the 2950's and some I don't.  Thanks.
