R211x-HP Flexfabric 11900 Layer 2 - LAN Switching Command Reference

27
After you change the link mode of an Ethernet interface, all the commands (except the shutdown
command) on the Ethernet interface are restored to their defaults in the new link mode.
Examples
# Configure Ten-GigabitEthernet 1/0/1 to operate in bridge mode.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port link-mode bridge
port up-mode
Use port up-mode to forcibly bring up a fiber port.
Use undo port up-mode to restore the default.
Syntax
port up-mode
undo port up-mode

Usage guidelines
You can use this command to forcibly bring up a fiber Ethernet port, and enable the port to forward
packets unidirectionally over a single link. In this way, transmission links are well utilized.
After you forcibly bring up an Ethernet fiber port, the fiber port stays physically up regardless of whether
or not a transceiver module or fiber connections are present for the port.
The port up-mode command is mutually exclusive with any of the shutdown, speed, duplex, and
loopback commands.
A GE fiber port cannot correctly forward traffic if you configure the port up-mode command on the port
and install an electro-optical module, 100/1000-Mbps transceiver module, or 100-Mbps transceiver
module into the port. To solve the problem, use the undo port up-mode command on the fiber port.
Examples
# Forcibly bring up the fiber port Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port up-mode
priority-flow-control
IMPORTANT:
This command is applicable to only SF cards.
