For CoreBuilder 9000: Applies to Layer 3 switching modules only.
Configures the Ethernet ports on your system t o support the PACE
Interactive Access feature, which ensures reliable timing by preventing
excessive Ethernet network jitter (the variation in the timing of packet
delivery that can cause garbled sound, jerk y images, and delays).

Important Considerations
■PACE technology is 3Com’s method to provide reliable timing, optimal
LAN bandwidth utilization, and data prio ritization for time-sensitive
multimedia and real-time applications, and data-only applications.
■PACE Interactive Access employs a “back-off” algorithm that enables
your system to control traffic flow on a point-to-point link with an end
station. When the network experiences congestion, the switch holds
packets. PACE Interactive Access prevents an end station from
“monopolizing” the link.
