The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs provide both local and end-to-end flow control if flow control is enabled. Similarly, disabling flow control disables both forms of flow control. The configuration of flow control is supported in the Command Line Interface (CLI), using the storm control command. The command enables 802.3x flow control for the switch, or on a per-port basis. Flow control only applies to full-duplex mode ports. The port-specific setting overrides the global setting of the switch. See, the Alcatel-Lucent 1850 TSS-5 Command Line Interface Guide for details.
Important!
802.3x flow control works by pausing traffic on a port when the port becomes oversubscribed. This results in dropping all traffic for short bursts of time during the congested condition. It can lead to the loss of high-priority and network control traffic.
