1. VTP Summary Advertisements are sent every 5 minutes (300 seconds). Is this timer programmable? If yes, how?
2. I have read in Cisco course material that VTP password is stored in MD5 format and can be 1 to 32 ASCII characters long. It's also mentioned that its 16-byte value. Shouldn't it be 32-byte value?
3. The book mentions three types of advertisements viz. 1. "summary advertisements", 2. "subset advertisements" and 3. "advertisement requests from Clients". Can the advertisement requests be sent by a switch configured as server also (3rd type of adverstisement)?
4. Summary advertisements are sent every 5 min irrespective of whether there is any change in the VLAN configuration or not. I believe, subset advertisements are sent only when there is a change in the VLAN configurations. Is my understanding correct?
