The status of PATH MTU Discovery support is displayed, where status is either: ENABLED or DISABLED. If PATHMTUDISCOVERY was coded on the IPCONFIG statement, then support status is enabled. If Path MTU Discovery support is enabled, then TCP/IP will dynamically discover the Path MTU (PMTU), which is the minimum of the MTUs of each hop in the path, necessary to prevent fragmentation of datagrams sent on that path. If NOPATHMTUDISCOVERY was coded on the IPCONFIG statement, then support status is disabled and large datagrams might be fragmented.
