Alcatel Unleashed

Hi Silvio,

Port is simulated down but blinking green and cpu is 100%.
This is strange to me, like he get from dummy switch on port 1/1/23 bpdu packets all the time and stuck there.
I try everything but still when is loop on dummy switch, alcatel cpu goes 100%.

Hi Silvio,

I want to with this configuration
qos no user-port filter user-port shutdown bpdu
policy port group UserPorts 1/1/1-24
qos apply
to shutdown port permanently, because alcatel switch when goes CPU 100% has no function. How to solve this issue?
Thank you,
Regards,

Hi all,

Could you tell me if I have loop on dummy switch who is connected to alcatel OS6360 how i can shutdown port without using loopback-detection?
I try this commands:
qos no user-port filter user-port shutdown bpdu
policy port group UserPorts 1/1/1-24
qos apply

This commands shutdown port ...

Hi all,

I solve issu with loop-detection by turning it off policy port group UserPorts.
How to turning off qos, now look like this:
qos no user-port filter user-port shutdown bpdu
qos apply


Thank you.

'show log events/swlog' maybe give you additional info.
when you physically remove the cable from the switch once the port is down, does the performance go back to normal?
other than this, no ideas.

Yes. everything is normal than.

Hi all,

On switch Alcatel-Lucent Enterprise OS6360-P24 8.9.94.R04 GA i configured ports 1/1/1-24 to protect from loop:

qos apply

and also

loopback-detection enable
loopback-detection port 1/1/1-24 enable

@silvio: yes it is compatible with cisco pvst+ and work fine.
