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".

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.

For my Lan, I have created two Vlan; Vlan 10 = for Users and Vlan 20 = For Database Servers,There are 15 Lan computer/laptop and 5 SQL database server (Dell Server) connected through same 24 port cisco 2960 switch. Means, 15 + 5 port occupied.
I have applied access list on cisco switch to restrict communication between vlan 10 and vlan 20.But My main purpose to create two Vlan is not for any kind of communication or restriction. My main Purpose is that Users traffic do not distrub or choke or affect the Database servers. then what will i need to do for that is VLAN Concept is sufficient for my concern OR I will need to buy seperate Cisco Switch to connect 5 database servers OR Else ?

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.

My understanding is that even layer 2 switches like the Cisco 3500XL can have 1 IP address for management. However, I cannot seem to figure out how to configure it to get it working in a router on a stick setup. I can manage the router through SSH, but I cannot SSH to the switch.

I have three 4506 switches with vlan 4 set as the management vlan. Switch 1 is connected to switch 2 and switch 3.
I can access switch 1 and 2 using telnet from the management vlan and both switches reply to pings. But from switch 1 or 2 I cannot ping or telnet switch 3. If I plug into switch 3 and I can ping and telnet switch 3 but not switches 1 or 2.
It is as if the management vlan 4 is not being passed to/from switch 1 and 3. The configs for the uplinks from switch 1 to 2 and 3 are the same. And the configs for switches 2 and 3 look the same apart from the port settings.
I have over 40 vlans running all that work fine between all the switches.

1. How I can manage those devices, the Switch and the router? What is the BEST SOLUTION to manage this devices?
2. I want to monitor the traffic on this environment, how I can do it? How I can monitor the traffic from customer A, Customer B, and my own LAN traffic, in terms of bandwidth that has passed throught my devices? Is it possible to monitor on MY LAN, or I have to monitor from the EXTERNAL switch?
3. How I can limit the bandwidth? I was trying to configure it using access list, with policy-map, etc....and limit this on each interface. [code]
The interface does not support the specified policy configuration and/or parameter values.Assigning a policy map to the output side of an interface not supported.With I few reading, I could see that the SWITCH 3750 doesnt support this configs.My INTERNET LINK is 30 Mbps, the ports on the Switch (WS-C3750X-48P-L) are Gigabit Ethernet.How I can limit the bandwidth here? For example, How I can limit a interface to 3Mbps..I was thinking about this:
- Limit the interface to 10Mbps: speed 10
- and limit the interface with 30% of this speed: srr-queue bandwidth limit 30
Does this work for both UPLOAD and DOWNLOAD?When the packets passes that 3Mbps limitation, will they be droped?

I have 2 Catalyst 2924 switch in a home lab. Both of them have developed the same problem at the same time (strange). I have tried all that I can think of. I can telnet to them but cannot access via the console port. On a telnet session I execueted a "write erase, reload" on one of them. As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
The console cable is fine, works for all other devices.

I've been assinged a task to connect our branch office with the head office, so that the IP Phones in the branch office can be connected to Cisco Call Manager at head office. To accomplish this they have given a Cisco 877 Adsl router a 10 Port 3-COM POE Switch and 3 Cisco 7911 IP Phones. Currently the there are 7 PC's Connected to 3 COM Switch which indeed is connected to a Internet router(Speedtouch). First I thought of connectiong the IP Phones to the Ethernet Port on Cisco 877 router but had to change my mind as the ports are non POE ports and I do not have adapters for IP phones. So I've decided to connect the Phones to 3 COM Switch and create VLAN's (DATA & VOICE) and pass the DATA traffic through Speed Touch and Voice traffic through the Cisco 877 router, but when I tried accessing the 3-COM Switch via Console I am getting Junk language( See the attachment for reference).
how can I pass through this Junk messeges and access the switch

i'm trying to enable command authorization for ssh as well as console access to a Nexus 7010 box (version 5.0). Following is the config:
aaa group server tacacs+ ACS5-1
server 10.12.19.11
server 10.12.19.12
source-interface loopback0
snmp-server enable traps aaa server-state-change
aaa authentication login default group ACS5-1 local
[code]....
As you can see, the default group configuration ACS5-1 for authenticatoin has applied to both defaults and console. But the command authorization does not appear to be applied to the console. As a result, when i login from the console and get authenticated, the command authorization does not trigger and i can run commands I'm not supposed to. In the configuration, I do not see "aaa authorization console" option unlike we have in IOS.

is it possible, to use a Catalyst Switch (in my case a 3560E) as a source for a console session to another Catalyst? In principle to use it as a console terminal server.

I have 6 of these WS-CBS3012-IBM modules that need to be configured but I cannot access the USB console port. I was told I could just get any DB9- to- USB cable and that would work. I did buy a DB9-to-USB cable and it did not work. I looked up the installation guide for this module and it just said the console cable is DB9-to-USB but with no part number.

I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.

I have a statck of 4 2960s switches, with POE powered access points on 2 of them. All of the access points appear to be functioning normally. For some reason, on 3 interfaces connected to access points, I get the following when issuing show interfaces status:
Gi3/0/9 connected: T 7 a-full a-1000 10/100/1000BaseTX
^
My question is regarding the "T" in the status field. I can't find any documentation on this.

I can use Putty to SSH into my new switch (Directly connected to my laptop with ethernet cable), but I cant log into my switch.
Sent username "admin"
admin@192.168.251.1's password:
Access denied
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.

I am setting up a new 2960-S switch and none of the recommended username and passwords combinations work. I have tried CIsco Cisco, <blank> cisco and various other permutations.
I have tried to reset the switch to factory defaults and it still doesn't work. The switch is currently connected to a 3560G and has been assigned an IP. If I try to access it from Network assistant it shows as unmanaged and I get prompted for a username and password.The switch is connected to another new 2960-S via a FlowStack module.

I can understand it 's one of those very basic questions , but how do I identify a Switch is Layer 2 or Layer 3 ?Looking through # show version command and checking the IOS version to be IP BASE or LAN BASE . Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?

Today in my rush to get home I plugged in a new 2960 stack and did a little bit of very basic configuration, but no passwords were set. I tried to telnet in and the message says that a password is required, but none is set. I tried the SDM as I hadn't turned it off yet and it is prompting me for a user/pass but I have no idea what to put in there. No console is available, it's a new office so no employees around either.
