v1.5.0 Bug reports and Comments

[sirhc]

It always could be a coincidence, but the first time was the day after the firmware update. And the fan issue started immediately after the firmware update. The fans are both clean and spinning fine.

I could give defaulting a shot. Since both problems appeared after the firmware update. It had never once complained about a fan previously.

I do have config backups for it, would it be better to default and enter everything from scratch, or default and then restore?

Thanks,

David

If you export and import the config you will get the same corrupted config.
Factory default manually set back up.

Adding IPv4 addresses to a vlan for watchdogs breaks management access to the switch if management is obtained from DHCP.

A little testing shows this is present in 1.4.8-1.5.0.

Upon logging into the switch from console I can confirm that the switch falls back to the last static that was configured for mgmt.

Code: Select all

******* Switch# show vlans

I should also toss in here that if you change vlan config on a port while the port is in the disabled state it will not pass the vlan traffic once enabled. To resolve this you must remove and re-add the vlan to the port after the port is enabled.

LRL,

Just fyi, I have been able to confirm this issue and it's being worked on.

Thanks. I discovered another interesting issue as it relates last night.

Upon trying to add an address to a vlan, if the config rolls back the SFP rolls back into an error/unknown state. Re-seating the sfp seems to be the only fix.

This is most likely an incompatible or defective SFP.

My guess is a soft reboot of the switch will also cause this, I talk about this in this post and others:
viewtopic.php?f=17&t=3351&p=22107&hilit=+sfp+insert#p22107

Or maybe try changing the SFP Port Speed Duplex From AUTO to 1G or SFP AUTO on the ports tab.

SFP modules like any other electronics have tolerances and very +/- especially when it comes to I2C communications which is the root of this issue as it is how SFP modules communicate to the switch and or router they are plugged into, not for data but for identification and state changes.

[LRL]

In the switch log it contains i2c errors after the occurrence, but never from a reboot. I might agree that it could be a suspect sfp, but ive witnessed this behaviour 3 times now on different switches and sfps.

Ive also discovered that a firmware upgrade or downgrade resets the sfp issue with pulling and reinserting. Strangle a reboot won't fix it.

What happens with i2c on firmware change that doesn't on reboot? Is there a way ti implement this in software so that if switch mgmt is still present that sfp issues could be resolved without a truck roll?

LRL,

Checkout 1.5.1rc7 - It has been tested and should fix this issue.

greetings - just unboxing a few ws-12-250-ac's that shipped with 1.5 firmware. in the first two we've powered up, we're seeing fan cycling that has been mentioned previously.

the switch powers, all seems normal, except the fan goes from 0 to full every 10-15 seconds. this is in an air conditioned office. the gui accuratly reflects the fan speed as it is spinning up and down.

note this is in a factory default state OR with a config on it. we HAVE exectued the 45 sec + 5 min defaulting procedure you guys request which had no impact on this behavior.

any tips or suggestions? we will continue to set these up and reply to this as we have more data.

Could you provide the logs on this switch? Set the option to 'All'.

This has been brought up a few time's, but has been proven difficult to replicate. Any extra details will help.
