Table 1 States of a local 25-GE interface on an S6850-56HF or S9850-32H switch
Peer device
Local interface state and operations for bringing the
interface up
S6820 switch series
By default, the local interface is down.
•
When the local interface is connected to the peer by using a cable,
perform the following operations:
{
Configure the local interface to operate in the same speed and
duplex mode as the peer interface. Do not configure
autonegotiation settings.
{
Set the FEC mode to BASE-R FEC for the local interface.
{
Execute the port media-type copper command on
the peer interface if the peer interface is one of
Twenty-FiveGigE1/0/1 through Twenty-FiveGigE1/0/8 and
Twenty-FiveGigE1/0/49 through Twenty-FiveGigE1/0/56 on an
S6820-56HF switch or an SFP28 interface on an
LSWM124TG2H interface module.
•
When the local interface is connected to the peer by using a
transceiver module, set the FEC mode to BASE-R FEC for the
local interface.
25-GE breakout interfaces split
from interfaces 1 through 32 on an
S9820-64H switch
Up by default.

•
By default, the local interface is down when connected to the peer
by using a cable. To bring up the local interface, perform the
following operations:
{
Configure the local interface to operate in the same speed and
duplex mode as the peer interface. Do not configure
autonegotiation settings.
{
Set the FEC mode to RS-FEC for the local interface.
•
The local interface is up by default when connected to the peer by
using a transceiver module.

By default, the local interface is down when connected to the peer
by using a cable. To bring up the local interface, perform the
following operations:
{
Configure the local interface to operate in the same speed and
duplex mode as the peer interface. Do not configure
autonegotiation settings.
{
Set the FEC mode to RS-FEC for the local interface.
{
Execute the port media-type copper command on
the peer interface if the peer interface is an SFP28 interface on
an LSWM124TG2H interface module.

The local interface is up by default when connected to the peer by
using a transceiver module.
S6850-56HF, S9850-32H Up by default.
When a local 25-GE interface on an S9850-4C or S6850-2C switch is connected to a peer 25-GE
interface on a different device, the interface configuration requirements are as shown in
Table 2 . For
interfaces to operate properly, you must enable link compensation (also known as training or CL72)
on both ends when the interfaces are connected by using a copper cable. This requirement is not
otherwise described in
Table 2 .
In Table 2 , the 25-GE interfaces (including 25-GE breakout interfaces split from a 100-GE interface)
are supposed to be connected when they use the default settings.
Table 2 describes only 25-GE interfaces operating at 25 Gbps. When a 25-GE interface operates at
10 Gbps or 1 Gbps, you only need to configure the same speed and duplex mode (do not configure
