Configuration Notes and Feature Limitations for IPv6 MTU

  • The IPv6 MTU functionality is applicable to VEs and physical IP interfaces. It applies to traffic routed between networks.
  • For ICX 7150, ICX 7250, ICX 7450,
    Please confirm
    ICX 7550, ICX 7650, and and ICX 7750 devices, the IPv4 and IPv6 MTU values are the same. Modifying one also changes the value of the other. For ICX 7850 devices, the maximum MTU value is 9380 bytes in jumbo mode.
  • For ICX 7150, ICX 7250, ICX 7450,
    Please confirm
    ICX 7550, ICX 7650, and ICX 7750, and ICX 7850 devices, the minimum IPv4 and IPv6 MTU values for both physical and virtual interfaces are 1280.
  • You cannot use IPv6 MTU to set Layer 2 maximum frame sizes per interface. Enabling global jumbo mode causes all interfaces to accept Layer 2 frames.
