This read-only Unsigned32 value (8-12, default 8) specifies the minimum transmit inter-packet gap used on this 10 Gigabit Ethernet (10GbE) client port. This gap is the minimum idle time enforced between transmitted Ethernet frames, and increasing it can be used to slightly throttle egress throughput or accommodate a client device with stricter timing requirements. For example, an operator troubleshooting frame loss on a client device attached to client port 3 might check whether this value has been raised above the default 8, which would reduce the effective bandwidth available to that device.
