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 3 RepliesI am attempting to monitor bandwidth utilization of the WAN port for the RV180 via SNMP and I am getting strange results. If a 256MB file is transferred from a remote server (without compression), the ifInOctets counter doesn't increment by anything resembling 256MB:
$ snmpget -v2c -c public 192.168.1.1 IF-MIB::ifInOctets.5 IF-MIB::ifOutOctets.5
IF-MIB::ifInOctets.5 = Counter32: 365402138
IF-MIB::ifOutOctets.5 = Counter32: 32610053
[Code].....
I'm reasonably certain that the .5 interface is the WAN port based on the value of ipAdEntIfIndex.X.X.X.X, but even if that were not the case, none of the other interfaces increment by a value close to the amount of data transfered. SNMP monitoring of a WAP121 on the same subnet returns expected results. I can only assume that SNMP on the RV180 is completely broken.
The router has the latest firmware available (1.0.1.9). There is only one network connection and the RV180 is the default gateway for all internal hosts.
I would like if is possible to stack a Cisco 4900M with a 2960S. I know it is not the most common situation but i need it.
View 1 Replies View RelatedI have a running setup having 2 Cisco 2960s 24 TS switch with Stack configuration. Now I want to add one more same Cisco switch. My questions are:-
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 4 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 10 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?

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.
I'm using a stack of four SGE2000P switches for a PoE video camera system. I've got the cameras in a VLAN and everything's working fine.
I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used? I don't see anyway to get to those interfaces from the main page, and I wasn't able to find a way to do any sort of percentage thing even on a regular interface.
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.
We currently have as our stack master a 24 port Non-PoE that we want to replace with a 48 port Non-PoE. The 48 port switch at one time was provisioned as switch 3 in the stack (not the master). Correct me if I am wrong, but theoretically all I should need to do to get this working is to shut off the existing master so it re-elects a master and then provision the 48 port switch as the new switch one and make sure switch 1 has a high priority?
Do I need to write erase the switch that is replacing the current master first?
I have a cisco 3750v2-48TS connected to a cisco 3750v2-48PS in a stack. The stack ports show up as down/down in the stack.Is there a limitation as to if they can be connected.? I mean can we have a PoE and a non PoE in the stack?
View 1 Replies View RelatedI'm polling a few thousand locations using IP SLA, I have responder enabled on all destinations, and I'm using 60 byte voice packets with a QoS policy.When I run an IP SLA Summary availability report, I have a bunch of locations showing 9% availability 8.5% etc. When I go to the actual collector, and pull up a graph of the same time period, that graph shows 100% availability.
Same collector, same data, just different views giving completely different results. I have to assume that the IP SLA summary report is wrong, these sites were not down 90% of the time.
Just a random though to go with that, I do have the IP SLA to only pull information during the locations operational hours, and I did pull the report from midnight to 11am, the statistics should have been gathered for 4 hours of the 11, which is still higher than 9%, and I would expect all of my locations to report like that, not just a few hundred.
All of the devices are similar in hardware and IOS, and I have verified on a handful that IP SLA responder is enabled, and I see the connections, I have also verified the source configuration via command line.

Initially there were 3 SSIDs configured but all of them were assigned a single interface and this interface was configured with the controller management IP address as DHCP server so that the WLC could assign IP addresses to wireless clients, guns and printers etc.
Issue: As part of PCI initiative, we decided to segment the traffic in multiple subnets based on type of wireless clients; so now there are 3 interfaces configured and each SSID is assigned a specific dynamic interface and each interface is configured to use the controller management IP address as DHCP server.
There are 3 scopes configured for each of the dynamic interfaces/SSIDs and DHCP proxy is enabled but wirelss clients are still being allocated IP addresses from the original DHCP scope that was associated with the dynamic interface originally assigned to all 3 SSIDs.
I verified the following:
1. Each SSID is assigned a different dynamic interface (Users, Voice and Handhelds)
2. Each dynamic interface is configured to use controllers management IP address as DHCP server
3. DHCP scopes configured with correct network information for each dynamic interface and enabled
