The following table summarizes requirements for the switching fabric capabilities:
Name of requirement | Description |
---|---|
LACP TCP/UDP hash balance mode | Level 4 LACP hash balance mode is recommended to support services that employ TCP sessions. This helps to avoid fragmentation and asymmetry in traffic flows. |
Multihome server connection support | There are two major options to support multihomed server connections:
|
LAG/port-channel links | The number of supported LAGs/port-channel links per switch must be twice the number of ports. Take this parameter into account so that you can create the required number of LAGs to accommodate all servers connected to the switch. |
Note
LACP configurations on access and server levels must be compatible with each other. In general, it might require additional design and testing effort in every particular case, depending on the models of switching hardware and the requirements to networking performance.
