I have a switch connect to 2 backbone(BB).
Now i saw the lights when connect to BB1 is not light but i do not know which command will show the root cause or troubleshooting.
I want to know its caused by hardware, physical port or whatever. Any on can sharing the experiences how to show and troubleshooting this issue?
I also checked the connection and port 1g is fine. Show tech-support is alread here.

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 enabled error disbled recovery with time interval of 600 seconds on my 2960 switch.
What exactly this command does? Pls explain
I am looking to simply monitor Port-Security , Error-Disable and HSRP. I would like to receive an email when any of these are triggered.
Port Security - Port Is shut down
Err-Disable - Port goes into err-disable state (securedown)
HSRP - When HSRP standyby changes are detected
I need to receive emails with any of the able are triggered. What is the easiest way to do this? I know SNMP is the main option but I have never worked with SNMP and dont understand it too much.
Equipment:
2x Cisco 1921 series routers
3x Cisco 2960 POE switches stacked
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.
Does the Model "WS-C2960-24PC-L" Supports IP Routing or not?

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:

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.

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 need to know the 172cisco 1 router support to IPv6 & it support to IPv6 then which IOS is required for it.Also I need to know the cisco 2960 switch is support to IPv6?

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?

View 4 Replies View RelatedToday 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.

I have configured each VPC for each floor and portchannel configuration on 2960s switch to communicate to 5K switches.

I have attached topology map of my infra and the configuration files also. 1st floor switch and 4th floor swich have same configuration except IP address and switch name.
If I knew the IP address of a host, can we know on which port on the switch its connected. The switch model is 2960
View 6 Replies View RelatedDocument at url... is quite interesting,One of these goes about the behavior of a switch (2960-S and 3750G) when QoS is not enabled vs the one when QoS is simply enabled with "mls qos".What additional commands, beside "mls qos", would be needed so as to simulate as accurately as possible the switch's behavior when QoS is not enabled?

I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?
