* '''Large buffers''': this mode uses a single large buffer for each packet which may improve the performance but does not use the ingress packet memory as efficiently and limits the maximum jumbo frame size to 9kB. | * '''Large buffers''': this mode uses a single large buffer for each packet which may improve the performance but does not use the ingress packet memory as efficiently and limits the maximum jumbo frame size to 9kB. | ||
* '''Disabled''': this mode disables support for jumbo frames and offers the best performance and efficient usage of the ingress packet memory. Jumbo frames will be discarded by the network interface. | * '''Disabled''': this mode disables support for jumbo frames and offers the best performance and efficient usage of the ingress packet memory.

=== External timestamps === | |||
When this option is enabled, the system will use timestamps contained in the packet data instead of timestamps measured at packet arrival. Currently, only the Arista timestamp format is supported. If this option is enabled, packets without an external timestamp will not be analyzed. The current number of packets that are dropped because they do not contain an external timestamp is displayed in the active interface overview table of the top-user dashboard. If there are no packets with external timestamps arriving the time of the packet processing will effectively stand still and most graphs will not make progress in live-mode. | |||
