If a physical interface has been assigned to a PEX port, you cannot assign the interface to any other
PEX port.
Make sure the PEX physical interfaces at the two ends of a PEX link are at the same rate.
The SFP+ ports on the LSU1TGS32SF0(JC755A, JG344A) and LSUM1TGS24EC0(JH194A,
JH202A) modules are grouped by port number in order, starting from 1. Each group contains four
ports.
The SFP+ ports on the LSUM2TGS16SF0(JH193A, JH201A) module are divided into the following
groups:
•
Ports 1, 2, 15, and 16.
•
Ports 3 through 5.
•
Ports 6 through 8.
•
Ports 9 through 11.
•
Ports 12 through 14.
If you use the SFP+ ports in a group for PEX links, follow these restrictions and guidelines:
•
You must use all or none of the ports for PEX links. The SFP+ ports can be assigned to different
PEX ports.
•
To shut down or bring up any SFP+ ports in the group, you must make sure all the SFP+ ports
have been assigned to or removed from PEX ports.
If you use the breakout ports of a QSFP+ port on the LSU1QGS8SF0(JG392A, JG393A) module for
PEX links, follow these restrictions and guidelines:
•
You must use all or none of the breakout ports for PEX links. The breakout ports can be
assigned to different PEX ports.
•
To shut down or bring up any breakout ports of the QSFP+ port, you must make sure all the
breakout ports have been assigned to or removed from PEX ports.
A PEX port must have a minimum of one physical interface in Forwarding state for its PEX to
communicate with the parent device correctly. If a PEX port has only one physical interface in
Forwarding state, the attached PEX will reboot when any of the following events occur:
•
The interface is removed from the PEX port.
•
The interface goes down.
Examples
# Assign physical interfaces Ten-GigabitEthernet 1/2/0/1 through Ten-GigabitEthernet 1/2/0/4 to
PEX port 3.
<Sysname> system-view
[Sysname] interface range ten-gigabitethernet 1/2/0/1 to ten-gigabitethernet 1/2/0/4
[Sysname-if-range] shutdown
[Sysname] pex-port 3
[Sysname-pex-port3] port group interface ten-gigabitethernet 1/2/0/1
[Sysname-pex-port3] port group interface ten-gigabitethernet 1/2/0/2
[Sysname-pex-port3] port group interface ten-gigabitethernet 1/2/0/3
[Sysname-pex-port3] port group interface ten-gigabitethernet 1/2/0/4
[Sysname-pex-port3] quit
[Sysname] interface range ten-gigabitethernet 1/2/0/1 to ten-gigabitethernet 1/2/0/4
[Sysname-if-range] undo shutdown
