I'm trying to configure the GigabitEthernet interface of the WS-C2960 switch to have a full duplex. Unfortunately, there is no option to configure this neither is the speed of that interface. But these options are present in FastEthernet ports. Is there a bug in SW version 12.2(35)SE5 that explains this abnormality?
View 6 Replies View RelatedI had a bad power surge yesterday that took out a 2960g switch and the APC UPS that it was connected too. when plugged in the fan comes on and the syst light stays amber and the rps, stat, duplex. and speed light stay lit and the port lights for ports 21-24 stay lit. plugging it into the console on boot I cant even see rommon, so i dont think its even booting. 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.

View 1 Replies View RelatedI have got a catalyst cisco 2960G series switch and via this switch I want to creat serveral vlans. I am getting a dhcp IP from a router and I want to setup my own vlan networks.
I plugged in the Ethernet cable that came from the dhcp router to port 16 of the cisco switch and configured the ports 1,2 and 3 for vlan 1, 2 and 3
the dhcp router has given me this IP 192.168.10.158 defautl gateway is : 192.168.10.1
when I plug in a PC to port 1 or 2 of the cisco switch I still receiving the IP from range 192.168.10.* but not from the range that I configured for the vlan 1 or 2.
Below is my startup configuration:

After configured all the switches with the above setting, the software still cannot wake all the pc's using LAN. Base on sniffing, i can't find UDP port usage by the software. Attached here with print screen from wireshark.
I am unable to access a series of switches connected together through a management vlan. I receive the message "The server xx.xx.xx.xx at level_15_access requires a username and password." Entering the username and password fails and the same username and password message returns. I am able to ssh into the switch with the username and password that fails trying to access the switch with the browser.
How can I check the username and password for access with the browser?

View 3 Replies View RelatedA quick one because I'm scratching my head trying to figure the difference between the 2960 LAN Base and LAN Lite IOS installs. I want to put a 2960 into a site which has as layer 2 link on dark fiber taking it elsewhere. This part I'm not concerned about - the WS-C2960--24TC will do what I need without issue - but I don't know if I can get away with LAN Lite, or if I need LAN Base.
I basically need V LAN's with associated SVI's, and a routed link on the up link port (I don't care if it's a switch port with an associated SVI or a no switch port and IP address), but it's got to be able to run OSPF. Can I do this with LAN base on this series switch? Or do I need to go for a higher series (3560?). I *could* get away with static routes, but my boss is walking death on them unless I can 100% prove they're necessary, so I'd rather not right that fight!

I recently picked up a Catalyst 2960G and am trying to get SNMP management working over IPv6. I have the IP Address set to the local link, and can successfully ping and telnet to the switch (so the network can get traffic to and from the switch). However, SNMP packets just seem to disappear. I am running WireShark on my machine, and I see the packets go out to the proper IP, but nothing comes back. When I check "sho ipv6 traffic", I can see where there are UDP packets that are received, but, again, none going out. Also, when I run "sho snmp", all of the packet counts are 0.
Here are some relavant snipets from my "sho run":

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?

View 1 Replies View RelatedI 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.

View 1 Replies View RelatedI 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.
View 1 Replies View RelatedI'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.

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?

View 2 Replies View RelatedI 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?

View 6 Replies View RelatedWe 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.
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.
