How to change LED behaviors on BYPASS ports when system in DC off state?

Purpose:

LED behavior can be re-defined to meet users's expectation.

Target Audience:

• User who is using FWA-3050 LAN BYPASS sku.
• User who has Linux using experience.
• User who has BYPASS know-how.

Steps:

1. Download Advanced LAN BYPASS Linux utility.

2. Find out corresponding BUS location for port 9~12

# lspci | grep -i eth
69:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection ( rev 01)
69:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection ( rev 01)
69:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection ( rev 01)
69:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection ( rev 01)

3. Extract Advanced LAN BYPASS utility and modify config file.

// following is an example for BYPASS ports with 2 segments.

# nano lbpcu.cfg
eth_name: eth0
SEGMENT: 1
BUS: 69
DEV: 0
FUN: 0

eth_name: eth1
SEGMENT: 2
BUS: 69
DEV: 0
FUN: 2

4. Make binary tool 'lbpcu' to be executable.

# chmod +x lbpcu

5.1. Re-define it if BYPASS ports are in BYPASS mode:

# ./lbpcu -SBL
Example: Set segment 1 50(%) duty cycle of 500ms period for bypass led indication. So use -SBL 1 50 5 will set 50(%) for duty cycle and 500ms for period.
Command: Set duty and period for bypass led indication.
Syntax: SBL <segment> <duty(%)> <period(100ms/count)>
Output: N/A
NOTE: This setting will apply to both segments on the same NMC card

# ./lbpcu -SBL 1 0 1
# ./lbpcu -SBL 2 0 1

• note: example above makes LED no constantly light up with orange LED when system in DC off state
• default value from factory would be:

# ./lbpcu -SBL 1 100 10
# ./lbpcu -SBL 2 100 10

5.2. Re-define it if BYPASS ports are in DISCONNECT mode:

# ./lbpcu -SDL
Example: Set segment 1 50(%) duty cycle of 500ms period for disconnect led indication. So use -SDL 1 50 5 will set 50(%) for duty cycle and 500ms for period.
Command: Set duty and period for disconnect led indication.
Syntax: SDL <segment> <duty(%)> <period(100ms/count)>
Output: N/A
NOTE: This setting will apply to both segments on the same NMC card

# ./lbpcu -SDL 1 0 1
# ./lbpcu -SDL 2 0 1

• note: example above makes LED no blinking when system in DC off state
• default value from factory would be:

# ./lbpcu -SDL 1 50 10
# ./lbpcu -SDL 2 50 10
