I reset one of our switches so I could changes the IP address and configure for a different location.
To reset the switch:
â¢Press and hold the Mode button. The switch LEDs begin blinking after about 2 seconds. Continue holding down the Mode button. The LEDs stop blinking after 8 more seconds, and then the switch reboots.
Wait for the switch to complete POST.
Verify that POST has completed by confirming that the SYST and STAT LEDs are green.
Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button.
Verify that the switch is in Express Setup mode by confirming that all LEDs above the Mode button are green. (The RPS LED remains off on this switch.)
Everything works fine until this point. I connect a straight-through Category 5 Ethernet cable to one of the Ethernet port on the switch front panel and to the Ethernet port on the PC.
The LED's on both bink on the switch it's green and on the pc yellow. And I can't get to the express setup page.
The switch home page loads. But if I click on the Web Console link, I get page not found.
I tryed it with different pc's and still the same. What am I over looking?
I am glad that my response helped you to see the things that you need in the configuration. Thanks for the rating.
If you are replacing a switch then the IP address to use is not an issue (other than being careful that it gets configured correctly). (I once configured an interface and gave it a subnet mask of 18.104.22.168 instead of 255.255.255.0 - it does not work without the right mask) And if you are configuring through the console you can go ahead and put the address from the switch that you are replacing and it will replace the existing primary address. It will leave the secondary address in the config and you should explicitly remove it with:
no ip address 10.0.0.1 255.255.255.0 secondary
The default gateway configuration from the old switch should be configured in the new switch. Then when you put the new switch into the network (assuming that all the connections are made correctly) it should come up and you should be able to telnet to it (or web browser to it) and do whatever you might need to do.
I am not sure why this switch is so different in its configuration but I will take a guess. some different models of switch were configured differently - in part because several of the switches are products that Cisco purchased and not that Cisco developed originally. Different people developed different products. So several of the products are configured using concepts from the original developers. Over time Cisco works to make the switches be configured more like each other.
I am confident that you can do the configuration (especially with a little backup support). Go for it :)
The question of addressing on the switch gets interesting (though I realize that some of it will not be as obvious to you as it is to those who have more experience). If you look in the config under interface vlan 1 you will find that there are two addresses (10.0.0.3 is primary and 10.0.0.1 is a secondary address). I was puzzled at first about this. But as I thought about it I realized that there is good reason for it. 10.0.0.1 is a valid address on the switch and you can access it (via telnet or via browser). As you configure the switch and assign a different IP address to the interface it is the primary address that gets changed. The 10.0.0.1 as a secondary address remains a valid address on the switch and your session would not be disrupted. Of course if you are doing this by the console connection then it does not matter much.
So what you need to do is to access the switch. Then go into config t. Then use the interface vlan 1 to get to interface configuration mode. then use the command ip address to assign whatever address you need for the switch.
Perhaps the more challenging part is to know what address should be chosen for the switch. Do you decide that? Is there someone else who administers the network who decides this?
If you need more explanation then please ask some more question.
