L2 Flow Exceptions; Learning Bridge (Lb) Flow Exceptions - Dell Force10 Software Defined Networking Deployment Manual

• TTL is decremented for traffic forwarded using L3 flows.

L2 Flow Exceptions

• If you specify a non-zero idle timeout value for an L2 flow, the flow is aged out according to the MAC address
table aging time configured on the switch if there is no activity or traffic. The idle timeout value specified in
individual flows is ignored. If the idle timeout value is zero, the flow is not aged.
• Flow priority is ignored for L2 flows.

Learning Bridge (LB) Flow Exceptions

• If you specify a non-zero idle timeout value for an LB flow, the flow is aged out according to the MAC address
table aging time configured on the switch if there is no activity or traffic. The idle timeout values specified in
individual flows are ignored. If the idle timeout value is zero, the flow is not aged.
• Flow priority is ignored for LB flows.
• Dell Force10 does not recommend station moves in an LB flow configuration.
• Parallel links or paths may not work in an LB flow configuration; Dell Force10 recommends using port channels
instead.
