Cisco 2960 Ios
Maybell Hughs
The Catalyst 2960-X family of switches are Ethernet switches to which you can connect devices such as Cisco IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers, routers, and other switches.
Cisco intelligent power management capabilities include enhanced power negotiation, power reservation, and per-port power policing. For information about configuring and monitoring PoE ports, see the switch software configuration guide on Cisco.com.
The 10/100 Ethernet management port connection uses a standard RJ-45 crossover or straight-through cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.
If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not require special drivers.
The console output always goes to both the RJ-45 and the USB console connectors, but the console input is active on only one of the console connectors at any one time. The USB console takes precedence over the RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive. Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45 console if the USB console has been activated and no input activity has occurred on the USB console for a specified time.
After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and reconnect the USB cable to reactivate the USB console. For information on using the CLI to configure the USB console interface, see the software guide.
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points or IEEE 802.3af-compliant devices. You must remove any cable or device that causes a PoE fault.
Link fault. Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors are monitored for a link-fault indication.
If your switches are stacked and you press the Mode button on any switch, all the switches display the same selected mode. For example, if you press the Mode button on the stack master to display SPEED, all the other stack members display SPEED.
The STACK LED shows the sequence of member switches in a stack. Up to eight switches can be members of a stack. The first eight port LEDs show the switch member number. For example, if you press the Mode button and select Stack, the port LED 1 blinks green. The LEDs for port 2 and 3 are solid green, as these represent the member numbers of other stack members. The other port LEDs are off because there are no more members in the stack.
When you select the STACK LED, the respective STACK LEDs are green when the stack ports (on the switch rear panel) are up, and the respective Stack LEDs are amber when the ports are down. SFP+ module port LEDs 1 and 2 on the switch show the status for stack ports 1 and 2, respectively.
The console LEDs show which console port is in use. If you connect a cable to a console port, the switch automatically uses that port for console communication. If you connect two console cables, the USB console port has priority.
The stacking-capable switch models support stacking with the optional stack kit. It has the FlexStack-Plus module (hot-swappable) that inserts in the slot located in the switch rear panel, and a 0.5-meter FlexStack cable to connect the FlexStack-Plus module ports.
The switch is powered through the internal power supply. The internal power supply is an autoranging unit that supports input voltages between 100 and 240 VAC. Use the supplied AC power cord to plug it into an AC power outlet.
See the switch software configuration guide on Cisco.com for network configuration concepts and examples of using the switch to create dedicated network segments and interconnecting the segments through Fast Ethernet and Gigabit Ethernet connections.
For some reason the PWR light on the Access point is Orange/Amber and ETH1 is off. I tried rebooting it and it does turn on green (power) then goes to Orange. Both Ethernet ports do come on and one goes off. My access point is directly connected to a Cisco 2960 switch with poe+. Can someone help? This is urgent. Thanks
Unless I missed it, you didn't show the output of the Aruba command above. Quite frankly, if it doesnt negotiate high powered POE, it will not bring up the second port and anything you are trying to accomplish with LACP will not work.
So thanks to Colin for pointing in the right direction I was able to figure this out. We are a college is cisco proprietary on our network infrastruture. Our Aruba APs range from the 205 to 225 with our controllers being 7210s.
So what we had to do was a few things. We heard that the aps required 30w and that the cisco 2960 switches only sent out 15w (unless you speficially tell it). Combine that with an ios that didnt allow for proper poe distribution, it only allowed for one link to work in a etherchannel environment (lacp, lldp).
Each interface that had an Aruba 225 required port-channeling. To do I checked the ios and if it wasnt the latest version I upgraded was to c2960s-universalk9-mz.150-2.SE10a. Almost immediately the links started working. Weird huh?
The configuration for each link and the port-channel follows. I made sure the links were shut down prior to the change and then reenabled them and voila they now work. Before this I never saw the ports with "bndled" on them. Now it is showing and works fine. I hope this helps someone out there. :)
Thanks for your help... I did put T on the direct port toward cisco switch with PVID of 1 and a member of all vlan, and still not working... so i decided to put the netgear as a dump switch and put native vlan 5 on my cisco switch to point to the management ip address of the netgear which within a management subnet address... and works fine...
With reference to attached file, we are running this type of topology in our network environment. When I connect link between EX3200 secondary switch and 2960 switch it causes loop in the network and network devices attached to these switches starts to be unpingable.
just a supplemental to Hedia's post: Cisco uses a proprietary variant of the spanning tree protocol: PVST and PVST+. This is what is causing the problem. Juniper published an excellent whitepaper that has a chapter about how to get Cisco and Non-Cisco switches to work togehter:
This is exactly what Cisco announced yesterday (June 4th) at our annual Partner Summit event. Cisco is introducing the next generation of its wildly successful Catalyst 2K switches with the new Catalyst 2960-X series of stackable Gigabit Ethernet access switches.
The introduction of the Catalyst 2960-X Series switches effectively allows customers to address the growth needs of their businesses, all with new intelligent services. The innovative capabilities of the Catalyst 2960-X are highly differentiated when it comes to comparable offerings, and will no doubt increase the competitive intensity in the market.
[2] Based on a mix of PoE+ powered wireless access points and Cisco DX650 Class 4 IP phone connected to 48-port configuration of Catalyst 2960-X. Includes savings from up to 27% lower energy consumption compared to competitor switch, and savings from Cisco EnergyWise, Energy Efficient Ethernet, Downlink Hibernation, and Switch Hibernation.
I want to confirm does this setup works well if we use Meraki APs MR44 with WS-C2960X-48FPS-L connected to Router ISR4000 series. I think we dont have requirement to have meraki switches with Meraki APs. at the moment we have old APs connected to switches and controlled by WLC in network. we want to remove WLCs and old APs(1800/2700 series).
My objective is to replace a Nortel 5520 stack with a stack of Cisco 2960s.The old working configuration was using mlt trunk between 5520 and BNT layer 2/3 switch. I will use LACP for the trunk between the Cisco and BNT switches, and PVST is activated on the Cisco.
So, the pb seems to be concentrated inside the bladecenter between inner switches and blades. Yet, in the previous working configuration under redhat, this interfaces were bound with mode 6 (adaptive load balancing). It seems that I should change for mode 1 active-backup...
SGNIC is pleased to announce the Invitation To Quote for two (2) Dell SonicWall TZ300 firewall and four (4) Cisco Catalyst 2960-X switches and provision of the relevant professional services to perform installation, configuration, migration and testing of the proposed network devices.
