    Hi Team,

    Someone know the maximum MTU value for physical and virtual interface for Juniper SRX 1500.

    Thank You.

    The srx1500 supports mtu up to 9192

    Hi Steve,

    If I have a design with Jumbo frame MTU 9000. 
    What is exact MTU Value should I to set in SRX1500 for crossing traffic ?
    What TCP MSS value should I to set too ?

    Juniper includes  header information in the mtu size so for untagged interfaces add 14 to your desired packet size and add 16 for tagged interfaces.

    But in most environments once going with jumbo frames I have generally seen running with the maximum allowed on the links.

    Naturally, both sides of connected interfaces need to be the same value to prevent mtu mismatch issues.

    MSS is typically driven more by the applications or tunneling in use across the network.
