Cisco Switching/Routing :: 2960G No LANBase-Routing Feature?

Feb 3, 2013

one of our switches (WS-C2960G-24TC-L). When I try to turn on the lanbase-routing feature using sdm prefer lanbase-routing, it gives me an error (Unknown command). I tried "sdm prefer ?", and lanbase-routing wasn't there (only qos, default and dual IPv4 & IPv6). The switch is running on image C2960-LANBASEK9-M version 12.2(50)SE5.We have another switch (WS-C2960S-24TS-L), running on image C2960S-UNIVERSALK9-M version 12.2(55)SE5, and I can enable lanbase-routing feature. If I upgrade the WS-C2960G-24TC-L to version 12.2(55)SE5, will it be able to do inter-vlan routing? Or is the switch itself totally limited to VLAN configuration only?

Cisco Switching/Routing :: Cannot Upgrade 2960G Switch

Jun 26, 2012

I have a few 24-port Cisco 2960G Switches (model WS-C2960G-24TC-L) that I upgraded to IOS Release 15.0(1)SE2 using the web interface. I am now trying to upgrade those switches with the new release, 15.0(1)SE3, however I seem unable to do it, I have tried this on two switches so far, both have been upgraded to SE2 just a couple months ago or so, and both of them will not accept the SE3 upgrade, basically, I can select the tar file in the web browser and click "Upgrade"  but when I do the status never changes from "Loading the tar file to the switch". I have tried multiple times from multiple computers using many different web browsers, including IE6 which is listed as supported. I have let it go for as long as 1.5 hours but to no avail.I also had a few idential switches here that had never been upgarded to SE2, I have had no problems loading SE3 onto them using the same method so it would seem that the tar file I have downloaded is valid.

Cisco Switching/Routing :: 2960g / How To Enable Multicast To Work

Jun 7, 2012

I have a 2960G that I keep on the bench as a work switch. I assigned an IP address to it. The techs have had trouble imaging workstations using GHOST. Do any config changes need to be made to enable multicast to work? Everything is in VLAN1 at this point and the GHOST server is also the DHCP server.

Cisco Switching/Routing :: 2960G - Switch Clustering Benefits?

Jun 11, 2013

I recently changed jobs and at the new location we are primarily running Catalyst 2960G series switches with the exception of one 3750. All of the switches are setup in a cluster with the 3750 being the cluster master. My question is what is the benefit of switch clustering? The entire network seems to be a bit over engineered for the our needs and I am hoping to scale it back a bit. For example, the the network was setup with VOIP QoS when there were no plans to even use VOIP. Also what procedures would I want to follow to disable the cluster to avoid any major outages? Assuming there is no real need for a cluster.

Cisco Switching/Routing :: 2960G Core Switch For 400 Users

Jun 7, 2012

I'm trying to decide what switch to use as a core for 500 users. I'm currently looking at either 2 x 3750X stacks or 2 x 4500s with dual SUPs and PSUs, both options will provide the number of switchports required without the need for additonal access layer swiches. Which switch option is best to go for here? All of our services will be located in our data centre which will be connected using 2 1000Mbps MPLS circuits. I wont need any advanced L3 features and we are not likley to scale over 450 users. Also is it ok to use the dual switch stacks or chassis to provide the collapsed core/access layer or is it best to have a dedicated core (using one of the above options with less switchports) and having a dedicated accesss layer using 2960Gs for example. Our structured cabling terminates in a single comms room so we wont need to distribute switches throughout the office.

Cisco Switching/Routing :: IOS Installation For Switch 2960G 48TC-L?

Oct 23, 2012

i had made a software upgarde on the switch 2960G series have no any passwords, when I fished the upgrade process after rebooting the device i found it need a UserPw to access device manager. i tried to use the default PW "cisco" but it dosen't work too.. after that i tried the password recovery process to rest the PW, but noway, but now i have addition problem, when i try the cmd orders "flash_init , load_helper , dir flash" to beginning  the password recovery process it shows the following:
The system has been interrupted prior to initializing theflash filesystem.  The following commands will initializethe flash filesystem, and finish loading the operatingsystem software:

After that the problem updated 
because I tried to install the IOS by Xmodem to reload the missing flash file.After finsh the TAR file loading and reboot the switch.......the LEDs of mode and Giga ports are lighted amber and not blinking,  i tried many times to follow the steps to connect the switch by the emulator and consol cable by holding mode button and connecting the power cable at same time the device does not work, the switch now still not blinking, now i try to read and understand how can i remove the corrupted files and install a new IOS for this switch?What shall i do.

Cisco Switching/Routing :: IP Igmp Filter Command On 2960G?

Jun 21, 2012

I am unable to configure an interface using the "ip igmp filter <profile #>" command on a 2960G running 12.2(58)SE2. The switch allows me to create a profile using the "ip igmp profile <profile #>" global configuration command. It also lets me enable filtering with the global "ip igmp filter" command (which I didn't see in the documentation). But, the command is not accepted when configuring an interface. "ip igmp ?" does not even show "filter" as a valid auto-complete when in configure interface mode, and the command is rejected if I try to enter it.
I verified the command worked on a much earlier version of IOS, so it must have broken somewhere along the line. I'm wary of moving up to 15.0(1)SE. Is that a major IOS change?

Cisco Switching/Routing :: Forwarding IEEE 802.3 Raw Packets Through 2960G Switch

Dec 5, 2011

I have a requirement to monitor downstream data feed from a remote site and feed it to multiple destination devices for recording.  The source data will be fed into a port on a Cisco 2960G switch then, using the monitor function, be forwarded to multiple interfaces.   This works fine for normal Etherent II traffic.  We tried a test using a device that generates IEEE 802.3 Raw packets ('type' field is used as a 'length' field) but found that while the traffic appeared to be accepted by the input port with no errors it was not forwarded to the destination ports, even when using the monitor function.  I did try the 'encapsulation replicate' feature with no luck.  It does not forward these packets even if I set all the ports into a common VLAN and let the switch just perform a normal switch function (non monitor).
if it is possible to get the IEEE 802.3 raw packets to pass through the switch and if it is, how to or what I need to do to make it work?

Multicasting.  The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10.  I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch.  On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10.  The 2960G switch has a workstation connected to it that needs to receive the multicasts.  How do I configure the 6506 and/or the 2960G to process the multicast traffic?

Cisco Switching/Routing :: 2960G / 3650G - Non-broadcast Traffic Appearing Across VLAN

Jul 5, 2012

We run a network of several 2960G and 3650G switches in a network with a number of VLANs. One one particular VLAN (let's call it VLAN 10) it appears that non-broadcast traffic (i.e. normal unicast traffic) is being copied to every port in VLAN 10 only on one switch . The traffic is not crossing trunk ports and does not appear on other switches that have ports in VLAN 10. We first spotted this by noticing that a UPS port had an unusual amount of activity on our port througput graphs:
This traffic at 4 am is not expected and this profile is repeated across all ports in VLAN 10 on this switch (a  WS-C2960S-48TD-L stack running IOS 15.0(1)SE3)\iffed one port using local SPAN (the UPS port) and discovered that this traffic was not broadcast, which was running at a normal low rate at all times. The traffic appeared to be unicast traffic from other ports of the sort you might see on a hub. It was from various hosts that live on VLAN 10, most (not all) of the conversations had one end station homed on the 'problem' switch. There are about 800 non-broadcast packets per hour and this is a busy VLAN so it does not account for all the traffic on the VLAN.

Cisco Switching/Routing :: Browser Access To Switch Fails (Catalyst 2960G)

How can I check the username and password for access with the browser?
I am trying to monitor switch performance.  Is there a good way to monitor switch performance with the command line interface?

Cisco Switching/Routing :: 2960G High Output Drops Only On Gigabit Switch

Feb 11, 2013

I just got a Cisco 2960G 24-port gigabit switch so that our HP servers can have a Gigabit connection to the network. I moved 2 servers to it (HP Proliant DL380's)  but they don't actually seem to be able to achieve even close to 1000Gbps. I ran same some LAN bandwidth tests and it was showing only around 200-300 Mbps between all of them. I also ran a network stress test utility, LAN Tornado, and it was showing packet loss as high as 60% when on gigabit, and only .07% when on 100Mbps.
-Both the NIC's and the switch ports are set to 1000/Full

-Currently using Cat5e cabling no more than 25Ft in length (I know Cat6 would be better but Cat5e is supposed to support Gigabit)

-All servers are on the same VLAN
Here are the port statistics when running just a stress test @ 10Mbps that had a 45% packet loss. What's odd though is when I set the servers and switches to 100Mbps, I get less than 1% packet loss.

I would like to find a pinout and voltage guide for the connector comming off the power supply so I can check the voltages coming off the power supply to tell if it is a bad PSU or if it took out the main board.

Cisco Switching/Routing :: 2960G Configuring Ether-channel On Stack-wise Stack

Sep 24, 2012

A site that i am responsible for has the following equipment installed: 

2 x 3750G Switches configured as a stack using Stackwise - Collapsed Core/Distribution Layer
5 x 2960G Switches as Access Layer switches
WAN connections into the Core/Distribution Layer are all Gigabit Ethernet over Fibre.This is a dedicated CCTV Network with 50 Cameras all streaming video into the Core (decoders connected to access switches)Each 2960G has 2 links to the Core/Distribution 3750G Switches, 1 to each switch - Gigabit.I'm running rapid-pvst on all switches, so spanning tree is blocking one of the ports and effectively halving the 2 gig bandwidth. Next year our customer is going to add in a further 50 - 60 cameras.After monitoring the current loading on the ports in use, we have suggested to the customer that the 2 connections to each should be Ether-channeled together. [code]
First interface takes commands no problem, keep getting the message that etherchannel cannot be configured across different switches in a stack when i try to put the second interface commands on.
