Adding switch stack to the SDA fabric using Autolan

Hello

Need to know the right order when using DNA Autolan to build the underlay .

Is it to build the switch stack completely and then it will be discovered as a single entity during autolan process ? or do I need to connect one switch to the fabric and then after I build the underlay come back to switch and start adding to it the other stack members ?

Thanks

Hassan

If your data cabling at the back of the switch stack is done correctly, then you do not need to configure anything. Assuming this is day 0 bring up and the switches (licensing and OS versions are same) are coming up for the first time out of the factory with PnP agent, the platform/system will decide who will become Active based on the lowest MAC address. When it calls home the PnP server/DNA Center, PnP will set the priority of that switch to 10 to make it as Active member and to ensure that after further reloads the same switch becomes Active

Example output below:

na-poc-11#show switch detail
Switch/Stack Mac Address : 2c86.d239.ef00 - Local Mac Address
Mac persistency wait time: Indefinite
H/W Current
Switch# Role Mac Address Priority Version State
-------------------------------------------------------------------------------------
*1 Active 2c86.d239.ef00 10 V08 Ready
2 Standby 2c86.d245.ef00 1 V08 Ready
3 Member 2c86.d2be.fc80 1 V08 Ready

Stack Port Status Neighbors
Switch# Port 1 Port 2 Port 1 Port 2
--------------------------------------------------------
1 OK OK 2 3
2 OK OK 3 1
3 OK OK 1 2
