Description

This command configures and activates QoS flow control.

 

When a 1Gbps local port is already online, and the qos flowcontrol command is issued, the pause

 

settings take effect immediately on that local port. However, when the link is toggled, pause is

 

re-negotiated. The local port will advertise the most recent qos flowcontrol settings. After auto

 

completes, the local port pause settings may change, depending on the outcome of the pause

 

negotiation, per 802.3 Clause 28B, as shown in Table 1.
