By default, an Ethernet
port is in up state.
To bring up an Ethernet
port, use the
undo
shutdown
command.
Note:
z
For a Combo port, after you execute the
undo
shutdown
command on the optical
port, the electrical port will be shut down automatically and the optical port will be
available, and vice versa.
z
For a small form-factor pluggable (SFP) port that uses a 100-Mbps module, the
duplex mode can only be configured as full, and the port rate can only be 100 Mbps;
for a SFP port that uses a 1000-Mbps module, the duplex mode can only be
configured as auto or full, and the port rate can be determined through auto
negotiation or be 1000 Mbps.
1.1.3 Configuring Flow Control on an Ethernet Port
When flow control is enabled on both sides, if traffic congestion occurs on the ingress
port, it will send a Pause frame notifying the egress port to temporarily suspend the
sending of packets. The egress port is expected to stop sending any new packets when
it receives the Pause frame. In this way, flow controls helps to avoid the dropping of
packets. Note that only after both the ingress and the egress ports have turned on their
flow control will this be possible.
Follow these steps to enable flow control on an Ethernet port:
