Cisco Switching/Routing :: Cannot Administer Catalyst 2960 Switch Via Console

Feb 20, 2013

I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch.  However, anything I type does not appear on the terminal client.  I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs.  I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
 
Here's the output of TeraTerm:
 
Boot Sector Filesystem (bs) installed, fsid: 2
Base ethernet MAC Address: e8:40:40:06:f0:80
Xmodem file system is available.
The password-recovery mechanism is enabled.
Initializing Flash...

[code]....
 
After the last line, I can not type any command at all.  I encountered this on three 2960 switches that we have here in our laboratory.

Cisco Switching/Routing :: Using Web Console To Manage 2960 Switch

Nov 13, 2011

I have a client whom has asked me to enable web management on some of his 2960 switches. I did not think this was going to be an issue, and so I told the customer I would set this up for him.
 
Much to my dismay, I have been able to get http and https enabled, and then authenticating locally for the HTTP access.  I then come to the screen once authenticated which is shown below:
 
The issue is that when I select "Web Console", it gives me a "Web Page Cannot be found".

It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.

Cisco Switching/Routing :: Catalyst 2900 XL Console Access Disabled

Jun 30, 2012

I just purchased a used Catalyst 2900 XL switch and have not been succesful in connecting to the console via minicom 2.5 running on Ubuntu 12.04 or 11.10, I don’t even get junk charecters in the terminal or echo on input. The switch passes POST according to the LEDs on the front and the network ports are fucntional for switching purpouses.
 
I’m using a Prolific PL2303 USB-Serial adapter, which works with minicom to console into another device.  I’ve tried every baud rate available and tried combonations of hardware flow control, software flow control, and niether.I’ve tested the pinout of the console cable and all pins map correctly according to Cisco spec.I’ve also tried Cutecom, putty, and screen. I have not tried HyperTerminal because I do not use windows.Is it possible that the previous owner disabled console access? Do I need to reboot the switch each time I test a different baud rate?

Cisco Switching/Routing :: Unable To Login To 2960 Via Console Through Terminal Server

Oct 23, 2012

I have a set-up with multiple C2960 and C3750 switches. All these devices are being managed remotely. So basically I login to C2901, which is used as a Terminal Server,  and reverse SSH to the console of each device. That's - I have assigned an IP to each port of the terminal server so that I can SSH directly to the desired device through via the mapped IP.
 
Now, recently I had to restart couple of switches - one C2960 and C3750. I initiated the reboot via console connection remotely. I could see the device logs for some time and then the logs stopped and there was no reaction from the console irrespective of any command I tried to enter.
 
I tried resetting the line on the terminal server, but that didn't work.
 
Now when I try to SSH the IP mapped to console of that particular device - i dont get any login prompt and there is no effect on device after giving any command. Although i can see the logs on the console session - but cant do anything.
 
I have a second way of connecting the device via inband- management, and checked the device config found it correct. It is same as other devices which are working correctly.
 
Both C3750 and C2960 are behaving exactly same - can see logs on console but see effect of even pressing enter - not getting login prompt as well.

Cisco Switching/Routing :: How To Stack Catalyst 2960

How would I go about stacking 4 Cisco Catalyst 2960-48PST-L switches? The one switch needs to accept a fiber connection from a distribution switch.  Do I have to buy flexstack module and cables? If so where does the module go on the switch? If this switch cannot do this set up, any other switch I should look at.

Cisco Switching/Routing :: Catalyst 2960 IOS Upgrade

Apr 9, 2012

I need to upgrade a Catalyst IOS, but I got a bit confused. The catalyst is currently running "c2960-lanbase-mz.122-35.SE5.bin", but I want to upgrade to "c2960-lanbasek9-mz.122-35.SE5.bin", in order to enable ssh. [code] What are the appropriate steps in order to upgrade to "c2960-lanbasek9-mz. 122- 35. SE5.bin". I have downloaded the tar file (c2960-lanbasek9-tar.122-35.SE5.tar)
 
1) Do I have to delete the old directory  (drwx 192   Mar 1 1993 02:07:21 +02:00  c2960-lanbase-mz.122-35.SE5)?
2) Are these the correct steps to download and extract the IOS?
3) Where will the tar files be extracted? Will an new directory be made or do I have to make one manually?

Cisco Switching/Routing :: Catalyst 2960 POE With Pre Standard IP Phones

Mar 21, 2013

I have a Catalyst 2960-S switch and a pre-standard IP Phone (Cisco 7960). When I connect the phone to the switch the switch recognizes the phone and supplies power. I would like to prevent this behaviour. ie. I would like to disable detection of pre-standard equipment. Is there a command I can issue on the 2960-S to do this? For example, on a switch from a different vendor I can issue the command: no power pre-std-detect to prevent it from detecting the 7960 phone, is there an equivalent command on the Catalyst 2960-S ?

Cisco Switching/Routing :: Catalyst 2960-S Stacking Connection

Apr 11, 2012

I followed the 3-switch Redundant stacking diagram and now when I boot up the stack Switch 2 is acutally Member 3 and Switch 3 is Member 2.
 
We plan on having Port-Channels spanning across Switch 1 - Master and Switch 2 (Member 3) of identical port types. Switch 3 (Member 2) is going to have 2 10GIG port channel created.
 
Is there going to be a problem renumbering the stack as they physically sit or should I just configure the devices based on thier logical member numbers.
 
I don't understand why the stack connection is Switch 1 - 1 ----> Switch 2 -1
                                                                    Switch 2 - 2 ----> Switch 3- 1
                                                                    Switch 3 - 2 ----> Switch 1 - 2

Cisco Switching/Routing :: Catalyst 2960 - Get Notconnect On Interface

Nov 20, 2012

At one of my sites, I have a 100mbit TLS. For this connection to work properly, the port on my end needs to be setup for 100mbit, full duplex. When I connect the TLS to an interface on my Cisco 2821, configured at 100/full, it works perfectly. Now the confusing part, I'm trying to connect the TLS to a Catalyst 2960. I configure the necessary port for 100/full, and get 'notconnect' on that interface. I set the interface to auto/auto, and it negotiates at 100/half and causes collisions and packet loss.
