In an ESRP (Extreme Standby Router Protocol) domain, the switch automatically calculates the port weight based on the bandwidth of the port. ESRP uses the port weight to determine the master ESRP switch.
For load-shared ports, configure the master port in the load-share group with the port weight. A load-shared port has an aggregate weight of all of its member ports. If you add or delete a load-shared port (or trunk), the master load-shared port weight is updated.
If you do not want to count host ports and normal ports as active, configure the ESRP port weight on those ports. Their weight becomes 0 and that allows the port to be part of the VLAN (Virtual LAN), but if a link failure occurs, it will not trigger a reconvergence. With this configuration, ESRP experiences fewer state changes due to frequent client activities like rebooting and unplugging laptops. This port is known as a don‘t-count port.
