Issue with a spanning-tree protocol

[mquijada09]

Hi, 

I have a problem with the spanning-tree protocol when I connect a printer on switch cisco C3560E. This is the Show Logging: 

*Sep 27 18:57:29.451: %SPANTREE-7-PORTDEL_SUCCESS: GigabitEthernet0/8 deleted from Vlan 600

*Sep 27 18:57:31.976: %SPANTREE-6-PORT_STATE: Port Gi0/8 instance 600 moving from disabled to blocking

*Sep 27 18:57:31.976: %SPANTREE-6-PORT_STATE: Port Gi0/8 instance 600 moving from blocking to listening

*Sep 27 18:57:32.731: %SPANTREE-6-PORT_STATE: Port Gi0/8 instance 600 moving from listening to disabled

*Sep 27 18:57:32.731: %SPANTREE-7-PORTDEL_SUCCESS: GigabitEthernet0/8 deleted from Vlan 600

*Sep 27 18:57:35.072: %SPANTREE-6-PORT_STATE: Port Gi0/8 instance 600 moving from disabled to blocking

*Sep 27 18:57:35.072: %SPANTREE-6-PORT_STATE: Port Gi0/8 instance 600 moving from blocking to listening

*Sep 27 18:57:37.068: %LINK-3-UPDOWN: Interface GigabitEthernet0/8, changed state to up

*Sep 27 18:57:38.075: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/8, changed state to up

This is the port configuration, this switch has been created the Vlan's L2: 

Show Vlan Brief:

600  PLT_SERVICE                  active    Gi0/8

Show access Port:

interface GigabitEthernet0/8
 description Zebra Printer 
 switchport access vlan 600
 switchport mode access
 logging event spanning-tree
 logging event status
end

Trunk Port: 

interface GigabitEthernet1/1
 description Trunk 
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,600
 switchport mode trunk

Please somebody help me. 

Regards. 

Thanks.

Hi,

So the port never goes to forwarding state?

Can you enable port fast on interface g0/8 and test again?

Below are there correct states when port fast is not enabled:

*Mar  1 00:10:55.267: %SPANTREE-6-PORT_STATE: Port Gi1/0/47 instance 1 moving from disabled to blocking
*Mar  1 00:10:55.267: %SPANTREE-6-PORT_STATE: Port Gi1/0/47 instance 1 moving from blocking to listening
*Mar  1 00:10:57.255: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/47, changed state to up
*Mar  1 00:10:57.264: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/47, changed state to up
*Mar  1 00:11:10.274: %SPANTREE-6-PORT_STATE: Port Gi1/0/47 instance 1 moving from listening to learning
*Mar  1 00:11:25.282: %SPANTREE-6-PORT_STATE: Port Gi1/0/47 instance 1 moving from learning to forwarding
*Mar  1 00:11:25.298: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

Hi,

Is the port passing any traffic? Can you ping the printer.

Thanks

Hi, John

Yes, the port passing any traffic. I Can't ping the printer, because the ping not respond. 

Also the port never is state UP. 

Anything else?.

Thanks.

Hi,

Have you replaced the cable?

What if you connect port g0/8 to a different device (PC/Laptop)?

[mquijada09]

Hi Reza,

Yes, I used various pach core.

Yes, I connected to a different device (PC/Laptop) and the port is idem status.

Hi Mariana,

Is this the only bad port on the switch?

What happens when you use other ports on the same switch?

Are all the other ports functioning correctly?

[mquijada09]

Hi, 

No, It isn't 

The status is idem. 

No. I used to different port and the result is the same.

Sounds like you have some sort of hardware issue.

Open a ticket with TAC. If loading a different IOS does not help, you may have to RMA it.

Hi, Reza 

Look this, I connected the printer in other Switch and the status is the same. The connectivity can't be established.

And in the same switch I probed with the Vlan 1 and can't established connectivity with the printer.

 I do not but, I think that the issue is for something in the LAN, some configuration I don't know.

Thanks.

I hope you helps.

Hi Reza,

No, the port never goes  to forwarding state and never UP.

Yes, I going to configure the port fast on interface.

This show I see in another interface, but not on interface where I connect the printer. 

I waiting any comment. 

Thanks
