flow-control (ACX Series)

Syntax

Hierarchy Level

Description

For aggregated Ethernet, Fast Ethernet, and Gigabit Ethernet interfaces only, explicitly enable flow control, which regulates the flow of packets from the router or switch to the remote side of the connection. Enabling flow control is useful when the remote device is a Gigabit Ethernet switch. Flow control is not supported on the 4-port Fast Ethernet PIC.

Note:

On the Type 5 FPC, to prioritize control packets in case of ingress oversubscription, you must ensure that the neighboring peers support MAC flow control. If the peers do not support MAC flow control, then you must disable flow control.

Default

Flow control is enabled.

Note:

Flow control is enabled by default only on physical interfaces and it is disabled by default on aggregated Ethernet interfaces.
