autonegotiation settings) for both ends and set the media type as needed. You do not need to
configure FEC or link compensation.

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 to bring up the interface:
{ Set the FEC mode to BASE-R FEC for the local interface.
{ Execute the port media-type copper command on
the local interface if the local interface is an SFP28 interface
on an LSWM124TG2H interface module.
{ 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
• 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 peer interface to operate in the same speed and
duplex mode as the local interface. Do not configure
autonegotiation settings.
{ Set the FEC mode to RS-FEC for the peer interface.
{ Execute the port media-type copper command on
the local interface if the local 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.
25-GE breakout interfaces split
from interfaces 33 through 64 on
an S9820-64H switch
• When the local interface is connected to the peer by using a cable,
execute the
port media-type copper command on the
local interface if the local interface is an SFP28 interface on an
LSWM124TG2H interface module.
• When the local interface is connected to the peer by using a
transceiver module, the local interface is up by default.
S9850-4C, S6850-2C
• When the local interface is connected to the peer by using a cable,
execute the
port media-type copper command on both
the local interface and peer interface if the interfaces are SFP28
interfaces on LSWM124TG2H interface modules.
• When the local interface is connected to the peer by using a
transceiver module, the local interface is up by default.
S6850-56HF, S9850-32H
• 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 peer interface to operate in the same speed and
duplex mode as the local interface. Do not configure
autonegotiation settings.
{ Set the FEC mode to RS-FEC for the peer interface.
{ Execute the port media-type copper command on
the local interface if the local interface is an SFP28 interface
on an LSWM124TG2H interface module.
• The local interface is up by default when connected to the peer by
