Reset Cisco Catalyst 2950 switch

[Enrique Soto M]

Hello,

What would be the best way to reset / configure this switch?

I have tried the reset procedure shown here (http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/45383-express-setup.html#trbl6) but even after reboot the switch would only work on a 192.168.0.x subnet. If I connect it to a different one it won´t take / deliver a valid address.

Thanks in advance.

Enrique Soto.

You will have to configure the switch via console cable and apply the address scheme that corresponds to your network on the switch.

I have the cable and serial port on my PC.Used putty but connection screen did not show any prompt character..Was I missing something?

Where could I find instructions as to what commands to type in order to set the right address range?

Thank you.
 

I've reset the config and accessed switch over terminal.
It remains the same though. While still connected via the terminal I get this error message in the same network where I had the problem before:

03:56:20: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/16, changed state to up

03:56:20: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/16 VLAN1.

03:56:20: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/16 on VLAN0001. Inconsistent ------------------------------------------------------------------------------

Do you have any idea what might be causing this error?

Thank you.

Post a copy of the config.

Here is the Config:
-----

end

End of Config.

NOTE:
IT Dept. of this rented offices indicated me some time ago to disable Spanning Tree option on the CISCO SF200-48 switch whose network I'm trying to connect this other switch to.

Thanks again.

Try this:

no spanning-tree mode pvst

[Enrique Soto M]

Done. But again got errors.

04:38:13: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/9 VLAN1.
04:38:13: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/9 on VLAN0001. Inconsistent port type.

Do you think BPDU Filter will help with this?

Thanks.

You will need to either configure spanning tree to match the other switch you are connected to or disable them both.
