Flow Control
IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed and
dropping all traffic for small bursts of time during the congestion condition. This can lead to high-
priority and/or network control traffic loss. When 802.3x flow control is enabled, lower speed
switches can communicate with higher speed switches by requesting that the higher speed switch
refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows.
To display the Flow Control page:
1. Click Switching > Ports, and then click the Flow Control link.
Link Trap This object determines whether or not to send a trap when link status

• Disable: Specifies that the system does not send a trap when the link
status changes.
Maximum Frame Size Indicates the maximum Ethernet frame size the interface supports or is
configured to support. The frame size includes the Ethernet header,
