To configure IP fragmentation for 7210 SAS

When to use

For 7210 SAS-Mxp, native IP fragmentation for IP packets exceeding the configured MTU is not supported by default. You can configure CPM to extract oversized IPv4 packets from the datapath, fragment them using the system CPU, and insert the fragmented packets back into the datapath.

Note: Even when IP fragmentation is enabled, packets that exceed the configured MTU are dropped if the Do not Fragment (DF) bit is set in the IP header.

Perform the following to configure the IP fragmentation for a 7210 SAS-Mxp site.

Steps


1	On the equipment tree, right-click on the required 7210 SAS-Mxp NE and choose Properties. The Network Element (Edit) form opens.
2	Click the General tab.
3	Configure the Allow CPU Fragmentation parameter.
4	Save your changes and close the form. End of steps
