Cisco VTP question

[santosh sahoo]

The VTP revision number increase by 1 while adding or deleting a VLAN. My question is , is  there a limit to the configuration revision number. I mean can the revision number can be goes to 10 digit number or even bigger.

Hi

It's a 32-bit number, so 4 million something. I don't know what happends when it gets to that number, and I don't have the time to find out :)

Hi Santosh,

The VTP configuration value can go high upto 2^32=4294967296. After reaching this value it will recycle back to 0.

I don't think any switch will ever reach upto this VTP value.

thanks for  the answer .  But where you get the value 32 ? If you can explain that will be great.
