ports of S3526E/S3526C Ethernet switches support 10Mbps, 100Mbps, and 1000Mbps,
which can be selected per your requirements. However, if the duplex mode has been
set to half-duplex, the speed cannot be set to 1000Mbps.
By default, the speed of the port is in auto mode.
1.2.6 Set Cable Type for the Ethernet Port
The Ethernet port supports the straight-through and cross-over network cables. The
following command can be used for configuring the cable type.

Note that, the settings only take effect on 10/100Base-T and 1000Base-T ports.
By default, the cable type is auto (auto-recognized).That is, the system can
automatically recognize the type of cable connecting to the port.
1.2.7 Enable/Disable Flow Control for Ethernet Port
After enabling flow control in both the local and the peer switch, if congestion occurs in
the local switch, the switch will inform its peer to pause packet sending. Once the peer
switch receives this message, it will pause packet sending, and vice versa. In this way,
packet loss is reduced effectively. The flow control function of the Ethernet port can be
enabled or disabled through the following command.
Perform the following configuration in Ethernet port view.
Table 1-7 Enable/Disable Flow Control for Ethernet Port
