Configuring LLT interconnects to use Jumbo Frames
You can configure LLT interconnects to enable Jumbo Frames by increasing the maximum transmission unit (MTU) for physical systems and logical domains.
For physical systems enable Jumbo Frames at interface and LLT-level.
For logical domains enable jumbo Frames for LLT inside the logical domain. You need to ensure that Jumbo Frames are enabled for the virtual network (vnet), virtual switch (vsw) and the backend physical interface. If a physical switch is used between any cluster nodes to connect the interconnect, ensure that MTU value of switch is also set to a value that matches with other network components.
Perform these steps on all nodes of the cluster
- Enable Jumbo frames at interface level.
- If its a physical machine, run these steps for all the interfaces to be used by LLT
# chdev -Pl ifc-name -a jumbo_frames=yes
where, ifc-name is the interface name.
- Run the command on physical as well as on LPARs.
# chdev -Pl ifc-name -a mtu=9000
where, ifc-name is the interface name.
- Reboot the system
# shutdown -Fr
- Modify llttab for 9000 MTU.
