i need to configure this switch in order to work first the 2 core switch for redundancy then each catalyst switch 2960 connected to the core with 2 uplink each uplink for each core switch that way i have rendundancy in the connection then i need one vlan ?i need to configure this switch to work perfectly with each other in best redundancy mode?
I am configuring a Cat 2960 port for connecting a VOIP phone, authenticated by MAB. On connecting the phone, I get the port authenticated and assigned to the correct VLAN, with LLDP-MED advertising the correct voice vlan. However, I then see no traffic from the phone on the switch. I can see the MAC address of the phone is learned in the right VLANs, but the mac address is showing as "Drop", which normally means the address is statically configured to be blocked. There is no static mac address table blocking configured on the switch.

I had a strange issue with one of my customer..Cisco WS-C3750X-48P Access switch was not reachable and after reload it started working.I would like to know the root cause of the issue. There were no logs and no errors in interfaces.Even Cpu utilization was not high. We have enabled arp inspection and dhcp snooping in the switch..Hope this will not make any issue..Also we have dot1x enabled on port..

i tried disabling the diagnostic monitor for the module, did a power enable module command and then reset it but it still fails. this is the third blade that i am replacing in a few weeks and i still get the same error. i am persuded that it is not a hardware since it is the third blade in a matter of weeks. after the module reset, i receive this error % module 3 is operationally off (FRU-power failed)
could an ios upgrade solve this issue? are there any ios related bugs?
I have installed a switch (3560) that was from another site and changed all it's config and hostname etc and it is now live, however the syslog messages still see the old hostname, what could be causing this?
View 3 Replies View RelatedI 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.
I have two WS-C2960-24TC-L Switch with Software Ver 12.2(25r)SEE6 with image c2960-lanbase-mz.122-35.SE5.bin and 12.2(25r)SEE1 with image c2960-lanbase-mz.122-25.SEE2.bin currently on it.
I want to enable SSH connections on the switches and believe I need to import the cryto image onto the switch. I would like to upgrade it to new version that can also support ssh connection but not sure which image to download from cisco. The switches are now live.

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'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?

A 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 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?

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.
