Cisco Switching/Routing :: SSH Not Working With 2960
Jun 4, 2012
I have an switch 2960 and i have made an SSH connection . But the problem is that whenever i try to open with my teraterm or putty it ask for username and after that password but does take the password. It shows an error of password what should be the problem.
Commands that i entered to make SSH
config# username admin password pankaj
config# ip domain-name home.local
config# crypto key generate rsa
config# 1024
config# ip ssh version 2

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.

We have 3 Nortel RG 9150 remote PBXs installed at a branch location, and they have been functioning well for years plugged into 3Com 4500 10/100 switches. These switches have a very basic configuration; nothing special. We are transitioning over to Cisco 2960 switches with very basic configurations. The problem is that when we plug the 9150 into the 2960 switch, the RX light flashes like it should, but the TX light only flickers intermittently. We cannot ping it from the switch or local router. Everything in this building is in VLAN 1. I've tried turning on full duplex on the 9150 and/or hard-setting the speed/duplex on the 2960 switch. The company that maintains our 9150 sent a guy out who was completely puzzled by this too. In some ways this seems too basic to be a problem, but it is. The twist on this problem is that the 3Com switch, which the 9150s are plugged into, is connected directly into the Cisco 2960 that I can't make them work on. Plug them into the 3Com, they work; move them upstream to the Cisco, and they stop, even after I reboot them.
Here are the port configs of the 3Com and Cisco switches.

I have some trouble with that policy-map on my 2960 or 3560 switches with LAN base 12.2(53)SE2. I want to use that feature to catch video traffic from webcams in laptops which can't send dscp values out of the box. This is my test config to check if the function is working: catch every traffic from my workstation for testing, access-list 101 permit ip any any, class-map match-all CL_TEST
1. I can't see any counters with the command "sh policy-map interface FastEthernet 0/1". Cisco tells that this command is not possible. But how I can see if the policy is working correct?
2. When I did the configuration I can't see any packets with dscp af41 on the out going interface on the switch with "sh mls qos int gi0/1 statistic" as I expected. After reloading the switch I see the pakets with af41. Okay for that moment. But.After that I changed something in the policy-map. Only "set ip dscp ef" for a second test.
Generating some traffic I see only packets with af41 as before I changed the policy-map. No traffic with ef on the outgoing interface.

I'm using Packet Tracer for testing since I don't have the actual equipment. I have configured etherchannel between two 2960 Switches. I have used the trunk ports FE 0/23 and FE 0/24 on both switches to create the etherchanel. I have connected one PC with each switch. The PCs are in the same VLAN and can ping each other. Howver, when I take down one of the links in the etherchannel, the other link does not take over and I get 100% packet loss. I don't know what seems to be the problem. I'm quoting the configurations below:
Switch0:
Switch#sh running-config
Building configuration...
Current configuration : 1179 bytes

version 12.2
no service timestamps log datetime msec
no service timestamps debug datetime msec

I have an existing stack of 4 x 2960-S switches connected by stack cables.I would like to add another 2960-S switch to the stack but am unable to as the 2960-S will only allow 4 x 2960-S switches per stack.how I would add the 5th 2960-S switch to the existing stack of 4 x 2960-S switches.

I have a 24 port 2960-S that is not communicating with a 2960-LST that it is directly connected to over fiber. The link is up on the LST but will not come up on the -S. What command should I use to bring up this link? I have tried no shut from the (Config-if)# prompt.

My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
I am working on the spreadsheet and it looks like this (Not totally filled):
2960s3560x3750x45064510Approx cost (Each, 48PORT, POE+, 10G uplink, Dual PS, IP BASE)

Layer 3 optDual SupsDual SupsConExpensiveExpensiveConNo Dual PSConLayer 2 OnlyCannot stack more than 4
For the MDF I would like to use 2 Nexus 5548's with FEX's, and the layer 3 daughter board. For the IDF's I was thinking of two 4010's.

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

I'm having a strange problem where I'm not able to get through a Cisco 2960-S L2 switch when connected through vpn, while LAN-WAN traffic is working fine.The situation on site is the following:When inside the network I'm able to get to the internet without a problem. The problem is within a vpn-session. When this session is succesfully started I can ping and manage the Cisco 2960-S switch, but I can't ping or manage the Dell switch from my laptop. I can however ping the Dell from the Cisco-switch. [code]

This will be this configuration for all input interface right ? For the Output part I'm lost, what do I have to do ? And for the 2960-2 do I have to put the same configuration ?

We recently updated a site2site link to metro ethernet, ISP call it 100mbps LAN Extension, but to me it is just QinQ over fibre connection. Most went well, one thing (annoying to me) is we can not ping our switches on both ends anymore.
We have a 3750 in headend and another 2960 on the other end. I used to be able to ping/telnet to the management IP from one to the other. Now we can not. I think the ISP is applying some configuration on ports of their customer-premises equipments (both are Cisco switches) but agent in ISP told me no. I thought there is some configuration on Cisco switch to block "MAC discovery" but i just can not remmenber what was that and google also failed me this time.

I currently have a network with (8) 2960 Cisco Switches. (6) of the 2960 switches are etherchanneled back to (2) 2960 switches in the computer room. I would like to setup QOS on the (8) switches, however the traffic is very differnt on each of the switches. I have video, ip phone, server, printer, PC traffic. I am not sure what the best method of separating this traffic into differnt QOS queues.

We are going to upgrade our IOS on our WS-C2960G-48TC-L. But before we do that i want to ask whats the best IOS release to choose. Why we want to upgrade is because our switch software now don't support ssh just telnet access
Switch details:
Model: WS-C2960G-48TC-L
SW Version: 12.2(25)SEE2
Image: C2960-LANBASE-M
I was thinking about upgrading the IOS to 12.2(44)SE6 are maybe i should upgrade it to a newer release?
One more thing we have a bunch of stacked 3750 switches, that also need to be upgraded.

I was configuring a new Catalyst 2960 switch and had forgotten to set the speed back to 9600 after downloading the new IOS software image. I finished doing all of my configurations and went in to line con 0 to change the speed back to 9600. The change was accepted and I did a 'wr' to save the change, but when I reload the switch it is back to 115200.

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.

At a college we have Ciscos 2960 and are trying to setup VLAN tagging and also using RST or MST. The traffic on the jack should get tagged vlan 248.We were told by the college that Ciscos in the labs will not work with the Alcatel switch that provides access to the lab. That Alcatel is in Bridge 1x1 mode. The college will not change the configuration on the Alcatel.We got the Ciscos to do VLAN tagging and can get network access. However the spanning- tree is not read properly. Cisco does not properly read the Alcatel's RSTP (since the Alcatel is doing tagging on the BPDUs). It places the root of the spanning tree under vlan1 instead of vlan248.
The college strongly recommends HP Procurves and we are using that as test.The following is the configuration on the HP and it works with no effort (it reads the spanning-tree information as MST)We will end up getting HPs instead, if the Cisco cannot work with the Alcatels.

i am trying to monitor some UPS equipment,for that i am using a cisco 2960 switch and when the UPS is down it sends a L1 loop.when the switch detects the loop the int in which the UPS is conected to will get a link and go up.now my problem is this, as you probeblly know the switch has a protocol which protects it from getting loops and cuasing all kinds of problems.i need to remove this protocol and allow the switch to get L1 loops?
P.si have tryed to use UDLD, KEEPALIVE, BPDU guard, down-when-looped and errdisable commands with no success?
