These guidelines and prerequisites apply to SLB-L2 configurations:
Set up as many as 16 servers per SLB group.
Establish up to two SLB groups.
For bump-in-the-wire configurations, you must directly connect servers to switch ports within an SLB-L2 group.
Ensure that SLB and SLB-L2 switch ports do not overlap.
Set up only one traffic distribution hash policy on a switch. If the application requires running SLB and SLB-L2 at the same time, the policy must be chosen carefully to work with both SLB and SLB-L2. In such configurations, you must use the slb l2 policy command to set up a policy that works with both SLB and SLB-L2. When L2 fields are in the hash policy (for example, src-mac, dest-mac, type, vlan-id, vlan-pri, or l2-sym), they will only be recognized by SLB-L2. SLB ignores these L2 fields settings.
