I've been doing a bit of experimentation today. For the tftp server, I have it running on the native port of a raspberry pi, so that I can see if the lights come on.
I verified that this isn't a problem with the Raspberry Pi, by unplugging the RJ45 from MGMT 1, and plugging it into my MacBook Pro. I noticed that when I plugged the network cable into my laptop, the connection and activity lights on the Raspberry Pi turned on. These LEDs have never turned on when connecting to one of the MGMT ports since this started. With the Raspberry Pi set to 192.168.1.49 and my laptop set to 192.168.1.48 I ran
tftp 192.168.1.49 then
get brocadebot.bin, which completed in 2.8 seconds.
For trying to get the copy working, I generally followed the following steps:
1. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
2. Run
ip address 192.168.1.50/24
3. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
4. Run
t2 followed by
8 (Ethernet Tests) then
6 (All Tests), as set out in the management workaround
5. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
6. Run
ip address 192.168.1.50/24
7. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
8. Unplug and plug back in the ethernet in MGMT 1
9. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
10. Run
ip address 192.168.1.50/24
11. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
12. Run
t2 followed by
8 then 6, as set out in the management workaround
13. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
14. Run
ip address 192.168.1.50/24
15. Run
copy tftp flash 192.168.1.49 brocadeboot.bin boot
I've also tried a number of different things:
- Power on Switch with Ethernet plugged into MGMT 1
- Power on Switch with Ethernet plugged into MGMT 2
- Power On Switch with Ethernet unplugged and then plug in after it starts
- Power On Switch with Ethernet unplugged and then plug in after I run the workaround steps
- Power On Switch and interrupt with `b` when prompted, which kicks out to the
Monitor> prompt
- Power On Switch and don't interrupt, which errors with
Bad image header, before kicking out to the Monitor> prompt
What I've noticed
* The copy always times out.
* MGMT 1 port always has only one LED on when the switch is powered, and this LED is consistent
* MGMT 2 Ports LEDs always come on a fraction of a second before MGMT 1
* MGMT 2 Ports are usually both on when the switch is powered, but after a cold boot, but sometimes only one is on, but it's inconsistent which one
* Interrupting boot with b when prompted seems to have no effect on which LEDs are on for the MGMT interfaces
* Booting with the network cable in either MGMT port appears to have no effect on the LEDs
* The Ethernet Tests only Mac 1 Internal Loopback Test passes, the others all fail with
Code:
CRC error count = 65535
Frame count = 65535
* Booting the switch without interruption results in
Code:

* Checking if removing the bad primary image, I ran
del primary. This changed the boot up logs to

* Running
reset only seems to cause the system to hang until it's cold booted
