- You are not advised to use VSs to deploy M-LAG, because convergence is slow when a VS is reset or a peer-link fails.
- The two devices that set up an M-LAG cannot be configured with DHCP snooping.
- To enable the DHCP relay function, the function must be configured on both devices that set up an M-LAG.
- You are advised to deploy the DHCP server and NTP server on dedicated servers instead of on switches, because switches have limited CPU computing performance and high protocol running pressure.
