port group interface
Use port group interface to assign a physical interface to a PEX port on the parent fabric.
Use undo port group interface to remove a physical interface from a PEX port.
Syntax
port group interface interface-type interface-number
undo port group interface interface-name
Default
No physical interfaces are assigned to a PEX port.
Views
PEX port view
Predefined user roles
network-admin
mdc-admin
Parameters
interface-type interface-number: Specifies a physical interface by its type and number.
interface-name: Specifies a physical interface in the interface-typeinterface-number format. No space is allowed between the interface-type and interface-number arguments.
Usage guidelines
Execute this command multiple times to bind multiple physical interfaces to a PEX port. You can bind a maximum of six physical interfaces to a PEX port. The physical interfaces are aggregated automatically for backup and load balancing. The default configuration is automatically restored on the interfaces after the assignment.
You must connect a PEX port's all physical interfaces to the same PEX.
If a physical interface has been assigned to a PEX port, you cannot assign the interface to any other PEX port.
When you use the 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 ports can be assigned to different PEX ports.
You must shut down all the ports in a group before you can assign or remove any of the ports to or from a PEX port. To bring up the ports after the assignment or removal is complete, execute the undo shutdown command.
To shut down or bring up any ports in a group, you must make sure all the ports in the group have been assigned to or removed from PEX ports.
The port grouping rules are as follows:
On the LSU1TGS32SF0 (JC755A, JG344A) and LSUM1TGS24EC0 (JH194A, JH202A) interface modules, the SFP+ ports are grouped by port number in order, starting from 1. Each group contains four ports.
On the LSUM2TGS16SF0 (JH193A, JH201A) interface module, the SFP+ ports 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.
On the LSU1QGS8SF0 (JG392A, JG393A) interface module, the breakout interfaces of a QSFP+ port belong to one port group.
A PEX port must have a minimum of one physical interface in Forwarding state for its PEX to communicate with the parent fabric. If a PEX port has only one physical interface in Forwarding state, the PEX will reboot if any of the following events occur:
The interface is removed from the PEX port.
The interface goes down.

Examples
# Assign physical interface Ten-GigabitEthernet 1/0/1 to PEX port 3.
<Sysname> system-view [Sysname] pex-port 3 [Sysname-pex-port3] port group interface ten-gigabitethernet 1/0/1
# Assign physical interface Ten-GigabitEthernet 1/0/6 to PEX port 4. In this example, Ten-GigabitEthernet 1/0/5 to Ten-GigabitEthernet1/0/8 are in the same port group.
<Sysname> system-view [Sysname] interface range name pex interface ten-gigabitethernet 1/0/5 to ten-gigabitethernet 1/0/8 [Sysname-if-range-pex] shutdown [Sysname-if-range-pex] quit [Sysname] pex-port 4 [Sysname-pex-port4] port group interface ten-gigabitethernet 1/0/6 [Sysname-pex-port4] quit [Sysname] interface range name pex [Sysname-if-range-pex] undo shutdown [Sysname-if-range-pex] quit
