and BIP protocols. Communications between a jumbo-capable and a jumbo-incapable end
system is a problem for connectionless protocols such as UDP and ICMP because they
are datagram-based and do not negotiate a connection.
Each system transmits frames sized up to the mtu value of the system if no router is in the
path. Any frames larger than 1,500 bytes are dropped if they are not supported by the
receiver. The only potential issue occurs with the ICMP protocol—“pings” larger than
1,500 bytes fail.
A useful technique in mixed networks is to logically segregate jumbo frame traffic from
standard traffic by using IEEE 802.1Q Virtual LANs (VLANs).
Using the System Editor to Configure MCP Networking
If you need to modify the existing configuration of MCP networking on your FS6200
Server to match your environment, you must configure MCP networking through the
System Editor of the MCP Console.
Note: Any networking configuration change you make must also be reflected in the MCP
initialization files. Refer to Appendix A of this guide and the TCP/IP Implementation and
Operations Guide for details on modifying the MCP initialization files.
You use the System Editor to perform networking firmware configuration and the
configuration information is stored in the PCD file.
The System Editor uses a matching algorithm to assign network processor numbers and
Line IDs to the adapters that are installed in the system. These assignments are presented
to the operator in the System Editor configuration tree view as the configuration default.
You can modify that configuration as needed.
The following features and rules apply to the use of System Editor when configuring
networking.
You can update the following networking characteristics:
• The network processor number of the network processor node.
• The Line Number of the line for a network processor node.
• Movement of lines from network processor to network processor.
• The EVLAN IP address on the I/O engine.
• The EVLAN IP address mask on the I/O engine.
• Enabling or disabling a line for MCP.
• Deleting a network processor node with no lines.
• Creating a new network processor node.
