Command Line Interface Reference for the ProSafe 7200R Series Layer-2 Switches with Static 14.2.7.1 no ip forwarding This command disables forwarding of IP frames. Format no ip forwarding Mode Global Config 14.2.8 ip mtu This command sets the IP Maximum Transmission Unit (MTU) on a routing interface. The IP MTU is the size of the largest IP packet that can be transmitted on the interface without fragmentation. The 7200R Series Managed Switch software currently does not fragment IP packets. • Packets forwarded in hardware ignore the IP MTU. • Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing interface. Packets originated on the router may be fragmented by the IP stack. The IP stack uses its default IP MTU and ignores the value set using the ip mtu command. Note: The IP MTU size refers to the maximum size of the IP packet (IP Header + IP payload). It does not include any extra bytes that may be required for Layer-2 headers. To receive and process packets, the Ethernet MTU must take into account the size of the Ethernet header. The minimum IP MTU is 68 bytes.The maximum IP MTU is 1500 bytes. Default 1500 bytes Format ip mtu Mode Interface Config 14.2.8.1 no ip mtu This command resets the ip mtu to the default value. Format no ip mtu Mode Interface Config 14.2.9 encapsulation This command configures the link layer encapsulation type for the packet. Acceptable values for are ethernet and SNAP. The default is ethernet. Routing Commands v1.0, November 2007 14-11
