Click Apply to save any changes for the current boot session; the changes take effect
immediately. Use the Maintenance > Save Configuration page to have the settings remain in effect
after a reboot.
Flow Control
When a port becomes oversubscribed, it may begin 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, a lower-speed switch can communicate with a higher-speed switch by
requesting that the higher-speed switch refrain from sending packets. Transmissions are temporarily
halted to prevent buffer overflows.
Note Flow control works well on when the Link Speed is auto-negotiated.
Use the Flow Control page to enable or disable this functionality. To access the page, click
Switching > Flow Control in the navigation pane. As shown in the example configuration in Figure 4-4,
flow control is enabled globally, which would enable flow control on all the ports in the switch.
Figure 4-4. Flow Control Page
Field Description
Enable Mirroring Select to enable port mirroring capability globally on the switch. Clear to disable the feature.
Destination Port Select the port to which packets will be mirrored.
Source Port
Direction
For each source port you want to mirror to the destination port, select the direction of the packets
to be mirrored:
Tx and Rx— All packets transmitted and received on the source port are mirrored.
Rx— Only packets received on the source port are mirrored.
Tx— Only packets transmitted on the source port are mirrored.
None— No packets are mirrored from this port (default).
The port selected as the Destination Port is greyed-out and unavailable for selection.
Note: The Source Port CPU can be mirrored to an external port to debug traffic to and from the
CPU.
