1) How can I do this...(Should follow the same process as I did before.
2) Could I do this without impacting the service. i.e. without rebooting the switch.
3) What should be the connection archiecture as of now since there is two switch so it is connected 1 -1 and 2-2. but for 3 switch should we require to change the connectivity.

View 2 Replies View RelatedI'm connecting the two devices above and I need an LC to SC fiber cable. It should be pretty simple but I've seen two different types of LC/SC cables - one is 8.3/125 and one is 62.5/125. I believe the 62.5 is an older cable type but when looking at the detail sheets for each of the SFPs I see that both of these support a 62.5 or 50 micron core size.
View 2 Replies View RelatedI was just curious about something with upgrading a 2960s stack.
To copy the image to the switches in the stack I use: Switch# archive download-sw tftp://x.x.x.x/filename
Does this also set the image as the boot image or do I still need to issue the boot system flash command?
can I just issue this command on the master switch and reload and the new config will be pushed to the rest of the switches?
I need to add two additional 2960S switches to my stack. I saw a diagram that showed how a 4 switch stack can be connected, but I couldn't find much detail on adding a switch to an existing stack (besides master election). The output below shows how the existing stack is connected and its state

I will need to break one of the stack rings between SW1 and SW2 in order to connect the new switches. Does it really matter which ring I break to connect the additional switches? Does one ring act as primary? If so, I'd rather not break that ring so this process is transparent as possible. Also, is there any benefit to disabling the stack port vs just disconnecting the cable?
I have an 2960S all configured, with vlans, ports configurations and others.Now, I bought other 2960S and two stack modules to create a stack with these 2 switches.We call:
-Switch1 (I have configured and in production)
-Switch2 (New switch, no configured)
Can I connect these two switches in stack without lost the configuration of my Switch1 and no turn-off this switch? Does not stop the users access?
I have a single 2960s without stack module. The stack port has a status of down, however I'd like to disable it so that it does not generate a false alarm in my NMS. The documentation states that there should be a command "switch 1 stack port 1 disable" but the switch (running 15.0(2)SE2) doesn't seem to be available. Is this a dcumentation bug or is the command not there at all?

applied an iOS update to a stack via tftp. I used the archive Download-sw tftp:// method. I rebooted the stack after complete and it never came back up. I discovered the master switch upgraded but not the member. The member was sitting there with all amber lights on and frozen after the iOS load. The master wouldn't finish boot until I removed the member from the stack. I had a version mismatch and they would not communicate.
View 2 Replies View RelatedI would like to use flexstack to stack two Cisco 2960S 48 Port switches (2960S-48TD-L) for redundancy. Each switch will have a single 10G uplink into our Nexus 7K. One switch in the stack will terminate to linecard 6 (N7K-F248XP-25) and the other switch will terminate to linecard 7 (N7K-F248XP-25). My question is how many flexstack cables are needed? Do I need only one cable or do I need two to connect the two 2960s ?
View 2 Replies View RelatedI have 2 Catalyst 2960S-switches configured in a stack. The uplink is configured as a cross-stack etherchannel. Now I want to upgrade the stack with a minimum of downtime for the connected hosts. The hosts are connected to the stack via cross-stack etherchannels. So my question is: How can I upgrade the stack and reboot the members with a minimum of downtime? If I use the archive download-sw command with the /reload-option, the stack is reloaded and the result will be downtime for the hosts while th stack is reloading. Is it possible to upgrade the stack and then reboot the members one by one in a controlled manner?

View 10 Replies View RelatedI have a stack of 2960S (c2960s-universalk9-mz.122-55.SE2.bin) and the master has failed (used to have a priority of 14). The second switch has become master (priority 1) as can be seen below: [code]
If I connect a new blank 2960S (same IOS) through the stack ports, will the master sync its config to the new one without causing problems?As I understand the new blank switch will also have a priority of 1 and will by default be numbered as 1. So if the config is correctly synced and I later on want to make switch 1 the master, I need to set the priority: [code]
I have a live 28port Catalyst 2960S switch. By live I mean that there is an essential piece of equipment plugged into this switch that can suffer little to no downtime. Over the course of time the number of devices patched into this location has increased to exceed the 24 ports available and we have had to resort to adding unmanaged switches to fill the need. We have acquired an additional 2960 & stacking modules that I would like to stack together, keeping the existing switch as the master. It is my understanding that the stacking modules are hot-swappable and that this member switch can be added without bringing the master switch down, thus creating zero down time for the financial server that is connected.
The steps I believe that need to be followed are as such: write mem to existing switch and backup to our TFTP serverinstall the stack module in the existing (while powered up) and new (while powered down)place the 2 redundant FlexStack link cables on both switchesthen simply power the member switch on After boot the member switch will get it's OS and configuration from the master and I can begin moving CAT5 cables from the unmanaged switches to the stack.
Is there a stacking cable that is "bent"?Im using this cable:"CAB-STACK-50CM", "Cisco StackWise 50CM Stacking Cable".But it takes up to much room in the back of the switch, is there such a thing as "bent" stacking cable.

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.

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.
In the Ciscoview, the uplink SFP interfaces of 2960S stack are represented incorrectly. The two uplink interface should be Ten1/0/1 and Ten4/0/1 but proved to be Ten1/0/1 and Gi4/0/25. There is no 1G SFP module, so that the interface gi4/0/25 doesn't exist. [code]

View 2 Replies View RelatedI have recently split the voice vlan (10) from the data network (1), and am wondering why my catalysts and router do not require an interface Vlan10 statement. In the past I used OpenBSD boxes to do the routing, and I first needed to configure vlan 10 on the interface before I could get inter-vlan communication to work. With these Cisco devices it works, and I am wondering if it is because of VTP, for the fact that the ports maybe just pass all traffic, or is there some other explanation? Below is the setup, and firmware is up-to-date on all of the devices.
When I plug a phone into the POE SGE, the phone turns on, obtains an address on the proper subnet, and conversations are clear (whereas without the ip nat inside on the new subnet the calls had a lot of static). Possibly the reason that it works is because the phones properly create the tcp/ip packet, and it hops over the trunks and creates the states so that traffic routes back properly. I will install wireshark to see exactly what is going on, but is there a simple explanation that I am overlooking?
I have seen a similar post here from last year about a 10/half connection, but this is different. I have a provider using a 2950 switch (they left CDP on so we can see it). And we have to be set to 10/full to make this connection (as you know 10/half connected here would be or is horrible). I have had this connection running on my 2921 router w/o issue but when I connect it to my 3560X, then I get no link light (shows down/down, not connected).
What else to know about what has been tried: Connecting link to switch with switch set to auto/auto (sp/dup). Speed is 10 (as it should be) but of course w/o the other side pulsing the voltage to know what to auto to, it defaults to half so this is unacceptabel, but, I do get a link light and can pass traffic, it's just a horrible experience.
Also tried the same setting speed and duplex vs. auto disco speed and duplex on other ports of the switch, no difference, same results. Also different patch cables, same results.
My current work around is to connect the providers 2950 (10/full) to my 2921 router @ (10/full) with a BVI to another port on the router which continues on to my 3560X at 1G/full. And this works just fine. Here's more info from my 3560X and the providers 2950:

I have C3750X with C3KX-NM-10G, and have-T SFP in slot 3 ( means it is not in SFP+ slot ).I need to set speed&duplex hard to 100/Full, but if I do the link goes down. I have the same settings on the other side, only IOS version is different.I tried other speeds - 10 and 1000, but no one works with Full. When I change duplex to Auto it works fine.The reason why I am doing this on C3KX-NM-10G is because I need to use NetFlow and cannot use the chassis' copper port. At the moment the ports are connected through a copper patch cord, but in full production there will be a radio link in between that requires 100M/Full to be set hard.I am trying to search for any document that would describe this limitation, but cannot find any. Also port capabilities do not indicate duplex could not be set to full:
