    Max UDP Datagram size?

    petersjncv Visitor

      Does the 3448 AOS R10 and up have any kind of setting (or something "under the hood") for the maximum datagram size allowed for fragmented UDP packets?

       

      In Ethernet networks, MTU size is typically set to 1500 bytes. Let's say we have a UDP datagram of 65507 bytes that will have to be fragmented into 45 packets ( Max UDP size of 65507 bytes / UDP size per packet of 1480 bytes ~ 45) to be transmitted across a network.  Given the amount of packets, would the 3448 drop any packets when the number of fragmented packets received exceeds some kind of limit?  Is there a max UDP payload size setting (or a maximum amount of fragments per packet) allowed on the 3448 and can this be changed through configuration?
