  • 1.  Question on RSTP port cost for 40G interfaces

    Posted 10-03-2021 05:44



    The RSTP port cost of 1G interfaces is 20K, and of 10G interfaces is 2K.


    What is the RSTP port cost of 40G interfaces?

    From what I've seen 500.


    On Legacy devices, (EX4500, EX4200) STP port cost depends on the number of physical interfaces in AE bundle. For example, AE interface made of one 10G port has STP cost 2000, and AE made of four 10G ports has STP cost 500, and so on

    Hope it helps.
