Is it possible to run VTP V3 on 2950 and 2960 switches. If so what version of IOS supports V3? Our 2960s are running 12.2(25r)SEE1, and 2950s are running 12.1(22)EA4a. Neither of which supports v3.
View 3 RepliesI am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature?
View 1 Replies View RelatedI have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?

View 7 Replies View RelatedI have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.
I have recovered some configuration files from my 2950 switches with the Configuration Archive Tool in LMS.
Now, I'd like to replace my old 2950s by 2960 switches, which have the same number of ports.
Will there be any issue if I copy the exact same config from 2950 to 2960 ? Will some features not work or is everything interoperable ? Here's an extract of the config :

I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.
which models of HP ProCurve or Dell PowerConnect support 64-bit IF-MIB counters, or for that matter any other manufacturer (Zyxel?) (snmpv2 or v3, OID .1.3.6.1.2.1.31.1.1.1.6)I believe pretty much any Cisco Catalyst above a 2950 do, however don't believe any of the SG series do. I realize I could pick up a 2960G for $1500-2k and be good to go, but I forsee a larger switch purchase in the future, but still could use a switch in the meantime that was able to allow accurate monitoring of closet uplink bandwidth?
View 1 Replies View RelatedI have a 2960S switch and nine (9) 300 switches. I have three VLANs configured on them, data, voice and management. Each 300 has unique data and ovice VLANs corresponding to their locations. All of the 300 switches connect to the 2960 in a hub and spoke network topology via 802.1q trunks. I can access devices between switches on the data and voice VLANs fine from any other switch. My issue is that from any 300 switch I can access the 2960 management VLAN interface without a problem, but I can not access the 300 switch management VLAN that I am connected to from the CLI. I do not use the GUI at all for management.
View 22 Replies View RelatedI am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?

I have to setup my first flex stack and wanted to make sure I do it right. I have the physical aspect of the stack down.

View 5 Replies View RelatedWe had a new building thats gone up and complete now and we're trying to get a ip phone working down that end of the school on a vlan. We seem to be having trouble with the VLAN going through on the 2960 switch but it works fine on our core 3560 switch.
There looks like a slight variation in the config of the switches, the 3560 switch supports the "switchport trunk encapsulation dot1q" command on the interface where as the 2960 doesn't support the "switchport trunk encapsulation dot1q". Is this why the vlan is working on the 3560 and not the 2960, or is it something else?

We're testing the reference system shown in the figure below.

QuestionWith these settings we aim at forcing our synchronization packtes to precede other kind of traffic and go from Equipment 1 to Equipment 2 with minimum jitter.Unfortunately we experienced high jitter when both synchronization packets and other traffic are sent through the systems.

There is a fiber connection that runs between both closets, that the previous tenant used to connect the switches. I have placed a Cisco 2960 switch in each location, and added one mini SFP gbic's to each switch. After attaching both sides, neither light up. I do a sh inter gig1/0/49 on each and shows 'down down' (not admin down).
What is the trick on getting these to communciate, do I need to configure these ports, and are they supposed to light up?
What I am trying to accomplish is to get the one closet that is completely cut off, communicating by logically stacking, or 'daisy chaining' via fiber.
I turned off the lights and popped the fiber out, and I do see a faint red light (I did not look straight into it), so I think the fiber is active.
