20 Most Recent Cisco Catalyst 2950 24x10/100 Mbps Networking Switch Questions & Answers


I have limited knowledge in this area, however if the switch is set to factory defaults, it should go something like this

hit return to start.
password = asking4
then type en and hit enter
password = trouble
then type config t
then your commands ?
Then type wr mem when done
Hope this helps .....

I recently had a client switch do this to me. The only way to get it working was to manually put the NIC on my laptop to 10 Mb and Half duplex. After calling Cisco and opening a TAC case, it was deemed faulty hardware.

If you have SmartNet (anyone buying Cisco should always buy SmartNet) on the switch, call TAC and open a case. It's probably faulty hardware.

Good Luck!

Hi, the ports themselves don't have an IP address. The switch has one IP address for online configuration. this model does switching only and doesn't use DHCP to issue addresses

yellow light on ports means the port is not working or was shutdown due to port security

Follow these steps

example

int serial0
ip address 192.168.1.1 255.255.255.252 ( give 1.2 to other end)
ip address 192.168.2.1 255.255.255.252 secondary ( give 2.2. to other end)

ip load-sharing per-packet

ip route destination network destination mask 192.168.1.2
ip route destination network destination mask 192.168.2.2

GOOD LUCK

Hi

Instructions
telnet to the IP address of the Cisco switch
Enter the telnet access password for the Cisco swict when requested, and then the "Enter" key.
Type "enable" at the command prompt, and then the "Enter" key.
Enter the Privileged Exec password when requested at the command prompt, and then the "Enter" key. Then enter "configuration terminal" at the command prompt, and then the "Enter" key.
Type "interface fastethernet0/1," replacing the "fastethernet0/1" with the name of an interface in which you wish to enable PoE, and then the "Enter" key. Then, while in interface configuration mode, type "power inline auto" and then the "Enter" key. Repeat this step for each interface in which PoE is required.
Type "end" at the command prompt and then the "Enter" key, copy running-config
Below is some commands to run, I don't have any power on the interface but this will show you if this is working...
SW1#sh power inline fastEthernet 0/1
Available:360(w) Used:0(w) Remaining:360(w)
Interface Admin Oper Power Device Class Max
(Watts)
--------- ------ ---------- ------- ------------------- ----- ----
Fa0/1 auto off 0.0 n/a n/a 15.4
Run this command to see the interface is up.....
SW1# sh interface fastEthernet 0/1 ' in protocol
FastEthernet0/1 is up, line protocol is up (connected)
SW1#sh cdp interface fastEthernet 0/1
FastEthernet0/1 is up, line protocol is up
Encapsulation ARPA

Holdtime is 180 seconds

You can only reset password this way:
1.
Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch.
Use the following terminal settings:
  • Bits per second (baud): 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow Control: Xon/Xoff
2.Unplug the power cable.
3. Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch
4. Release the Mode button when the SYST LED blinks amber and then turns solid green. When you release the Mode button, the SYST LED blinks green.
5. switch: flash_init
6. switch: load_helper
7. switch: dir flash:
8. switch: rename flash:config.text flash:config.old
Rename config.text to config.old. In that file the password is stored.
9. switch: boot
10. Enter "n" at the prompt to abort the initial configuration dialog
11. Type en to enable
12. Switch#rename flash:config.old flash:config.text
13. Switch#copy flash:config.text system:running-config
14. Overwrite the current passwords:
conf term
enable secret <new pass>
enable password <new pass>
line vty 0 15
password <new pass>
login
line con 0
password <new pass>

15. write memory
16. copy run start
