LAN ports are amber after download config using TFTP

Hi,

I'm struggling with download of a config file from a serverlocation to a 3560 switch. I recieved a new switch and configured it manually. Ahtis this succesfull action and tested the config, I uploaded this config using TFTP to a server location. I clreaed the config on this switch ( reset to factory), connected the switch with a LAN port to the network, booted up the switch, connected via console to the switch and downloaded the saved config from server location to the switch using TFTP. All seems to be ok, but when I connect the switch with fiber to the network, Fiber is OK but all LAN ports are AMBER.

speed and duplew set to auto,no shutdown, same problem

anyone some ideas

Hi,

What type of interface is that port , check that is capable of Fibre optic(Gigaethernet). Also check your fibre as well.It could be the configuration you upload from TFTP Server has different interface as what you have now.Are the switch the same model?

Hi,

all ports are fastethernet ports directly connected to PC

Gigabit ports are working fine

Did u tried show interface and analyze the data

Werner,

Have you created the layer 2 VLAN on the switch?

switch#conf t

switch(config)#vlan 2

HTH,

Mark

interface FastEthernet0/41

description USER - vlan 2 backbone

switchport access vlan 2

no snmp trap link-status

no cdp enable

spanning-tree portfast

interface GigabitEthernet0/1

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 1,2,1002-1005

switchport mode trunk

udld port

spanning-tree vlan 1-3 cost 5

!

interface Vlan1

description NMS default VLAN

ip address 192.168.38.21 255.255.255.192

no ip route-cache

no snmp trap link-status

!

this config I entered first manually and this works.

Only when I install the config using TFTP I have the problem

Add the following to your TFTP config.

vlan 2

name User VLAN

If this does not help, please post your TFTP config.

Mark

As suggested by Mark check have you created vlan2 before you assign port to that vlan.

Light is amber when STP is blocking . Can you check is spanning tree is blocking ur ports

conf t VLAN 2

int vlan 2

description user - vlan 2 backbone

No ip address

same problem

sh spanning-tree blockedports

no ports blocked

can you tell me what need to be configured for TFTP? Is this realy needed as i can download the complete config from tftp server.

just asking as I'm not so familar with this.

There shouldn't be anything special to configure the switch from TFTP. Are you able to post the TFTP config?

Mark

do you mean the configuration that will be downloaded by TFTP

for the moment when entering after reboot switch

conf t

Vlan 2

no shutdown

it works

Yes the configuration downloaded by TFTP. If that is the solution that works for you just add "no shutdown" under VLAN 2 on your TFTP configuration.

I entered the command no shutdown for vlan 2

and ports are working

did then a copy run to start

uploaded config to server with TFTP

Copy system:/running-config tftp://........B

Copy startup-config tftp://........S

downloaded the running config using TFTP to the switch same problem after manually no shutdown" under VLAN 2 it's working

reseted the switch

downloaded the startup config using TFTP to the switch same problem after manually "no shutdown" under VLAN 2 it's working

Try this config. I added vlan 2 and added a no shutdown to the VLAN interface.
