addition of 3750 to stack

Hello

I have two 3750 s stacked and a 3750 autonomous all in a data closet. Both have the same versions. I want to combine them to make a pile.

Issues related to the:

How can I force the stand-alone version to be the master? priority of SW 1 XX (Higher then the existing battery)?

The battery and the standalone version have management addresses. It would be ok to remove the ip address of the stack? In this way, the standalone version (the master address will be the only address to management)?

How can I connect the stand-alone version of 3750 to the battery? Currently, 3750 battery is connected via a waterfall from the stack port cable 1 to the top switch to the port of stack 2 switch at the bottom.

Thank you, Pat.

Well, what I got out of this thread, you wanted the stand-alone battery/switch to be the master, then add the stack 2 switch to autonomous battery/switch? I guess that's correct. I'm sure that if you set the priority of 15 it takes affect immediately, but I was able to deceive. But, setting priority to 15, putting in orders for the supply and configuration of the interfaces should be no downtime.

3750 x stacking

Hello

I have a stack of 5 3750 x switches installed and I have another place with 1 switch, I took one of the 5 switches (last switch # 5) and he stacked to the stand-alone switch. everything works fine, except for the interfcaces, he continues to consider the switch to # 5, not No. 2 in the new battery.

I have reset the configuration to the swwitch that I added to the battery again.

NVI any idea how to change that to make interfaces begin with 2/0/x? instead of 5?

one last thing, I have boith cheating connected with the battery supply cable, however, it does not, any command I have to run on the switches?

Thank you.

Use the command "switch 5 renumber 2" and reload.

3750 X stack and question wccp ACNS Content Engine (CE)

Hello

I work with 3 3750Xs in a 'carrot' and we have a directly connected content engine (CE) on a WAE-612 CNSE ce612 - filtering 5.5.23.2 running web services. We use the wccp with forwarding L2 and L2 return with assignment of MASK.

The this is located in the vlan 1013 and is directly connected to the 3750Xs of base via po5. Users are in vlan 72 a stack of 3750Xs in a closet of access that is connected to the base through PO4. 64 VLANS plugs on the perimeter (to the Internet) firewall.

When only one member of PO4 is physically connected web filtering works, however the web filtering does not work when several members are connected in PO4 and end-users are not filtered. It seems the 3750Xs kernel redirect not the traffic to THIS more at this time.

Anyone have any ideas why adding members to the port channel seems to break the wccp functionality. Would it be due to the "Battery cross" of the channel port?

Here are some details of the 3750 basic configuration s

If you have more than 4, then divide into 2 batteries for power purposes; You can stack yet all 5 or 6 for network management purposes.

switch 3750 EAPoL transmission RADIUS server

I have a running version of the 3750 switch stack 12.2 (53) SE2 IPBASEK9-M. I have dot1x configured on the switch and a Windows 7 PC, connected with 802. 1 x configured on the interface. I see the EAPoL start message from the PC, but I do not see the packets from the switch to the RADIUS server RADIUS. I have a config simple dot1x just to try to make it work before adding additional features such as comments - vlan...

Config and debug of attached file.

I don't know if the configuration ip dhcp snooping and arp of inspection is cause a problem with that or not. I see the EAPoL packet received on the switch, as shown in the attachment of debugging, but I never see the RADIUS packet. I've defined both trust on the interface, but always the same result. I can't turn it off because there is a switch of production with a test interface.

Any ideas?

Thank you

Mark

I had the same problem and solved it is enough to configure the switch as authenticator instead of "supplicant". "Supplicant" means customer, "authenticator" means in fact the switch acts as an authenticator to pass through, it will forward the requests to the auth server, for example, host of RADIUS.

How to use 3750 in any configuration of the battery

We have just received a 3750 that has been configured as a member of the stack. They just turned off the switches and send a us, and I would like to use it as a stand alone with no configuration of the battery. I have tried everything I know, and he still regards as his share of a pile. Do I need to use a different IOS? Is it possible to use 3750 without stacking it? No idea how to get it to function as a stand-alone switch completely?

Thank you

Hi Isala,

I understand the configuration you need, but as we think we can see that you will definitely use 3750 2 switches and they won't have to connect through a cable of the battery.

If they do not have to connect through a cable of the battery then they will certainly not going to be in the same stack thsu they can work as master of the battery and that will not affect them.

And as we know that HSRP is standard Cisco allowing the high network availability by provide redundancy to first jump to the hosts IP on an IEEE 802 LAN configured with a default gateway IP address. If switch 2 will work individuallly so they are not stacked.

If you want you can even chat with me on 408-916-9070 Ext 3076

BlackBerry 10 BB loader

Hello!
I know that those with Apple products that are purchased in the United States (who have Chargers US) can use only a map of the EU and on the charger itself is written something like this - "110-240V 50 - 60 Hz", which means that it will work on electrical systems the most common world-wide without a transformer.

So my question is this:
Is it safe to use an adapter for charger BB? I mean if I have a classic US for BB charger and want to charge my phone in European Union, then it will be safe (which means that my battery does not burn or won't break not peripheral) using only a map of the EU? Take a look at this picture to better understand what I mean: I want to use this - http://drh2.img.digitalriver.com/DRHM/Storefront/Company/bbrry/images/product/detail/Passport/Charge... In ADDITION, this - http://i.stack.imgur.com/d5cum.jpg , which will look like this - http://img.banggood.com/images/upload/2012/liuguanglian/SKU09164501.JPG .

The charger BB has the same information about voltage as the Apple charger? ("110-240V 50 - 60 Hz")

It is not question of BB classic specific but especially '' in general '' on all products BB, because for all I know the BB charger can be used on almost all BB devices.

Thank you.

Pavels

Yes, they are. If you look at the charger, it should also be on it (even if very small letters):

Input: 100-240 V

I have an original Blackberry charger with US plug, plugged into a map of the EU and a power 220V in Europe. This works perfectly.

What are the optimal values for mac and arp timeout values

Hi guys.

What are the best values for 'mac address-table-time of ageing' and "arp timeout" by following scenarios? :

-single sg300-10 as hosts Layer 3 - with a maximum of 10 local switch (directly connected)

- and a 3750 x-stack with 100 local hosts + hsrp with a battery of the same kind

or for asa 5520 as internet gateway for 500 customers?

I use now a time of aging mac 300 seconds and a time-out of the arp of 3600 seconds.

Is - this okay.?

Thank you.

These values should be fine. I don't know why the switch is layer 3 since you have of the 3750 and the ASA5520. If you start to see overflow errors, you should consider using the layer 2 switch.

Switch of the battery with etherchannel configuration

Hello world

I have 2 3750 switch stack.

I have config etherchannel between them.

Here is the result

2 Po2 (SD) LACP Fa1/0/15 (I) Fa2/0/15 (I)

The two ports are up on the rise but autonomous

Int port channel 2 is low down.

Need to know if it is a default when we config etherchannel between the switches to the battery?

Thank you

Mahesh

Hello Manu,

If the switches are stacked, they are logically a switch. You cannot use portchannel to connect one switch to another.

You're basically looping ports together.

CDP support in TC4.2.0 for the C Series codecs

Hello.

I saw in an administrator's guide (TC4.0) EX TC4.2 was to support the CDP.

I don't see anything in the software and I was wondering if anyone knew if or when CDP support would be available.

We run Auto SmartPorts on 3750 X stacks for the codecs in the series C with active DHCP, but the macros seem to cause high CPU utilization on batteries with more than 6 switches.

CDP would be a nice alternative.

Does anyone have news?

See you soon

David

CDP is available in TE4 and is planned for TC5.

PS: The TC5 is coming soon.

Concerning

Group of channels on 2 switches

I have 2 24-port Catalyst 3560 switches (call them, one switch and switch-b). They are connected together by a cable connection and not stacked (the c3750 is stackable but not the c3560). Is it possible to have a group of ports-channels with 2 ports, where a port is A switch and the other is the B switch? If not, is it possible if 2 switches are stackable as c3750 switches? Thanks in advance. -Sam

Hey Sam:

Stacking, in the sense used by the 3750 switches and channel groups really have nothing to do with each other. Of course the 3560 cannot stack in this sense, but groups of channels are certainly achievable on these switches.

However, if you want to split the Group of channels so that half is on a switch and half is on the other, requiring correct stacking. This works on a set of 3750 switches stacked certainly, but will be not feasible on two 3560 units.

Grouping of NETWORK cards causing the ESXi to retransmit ethernet frames received.

I had an HP Proliant DL380 G5 ESXi 5.1.0 connected to a Cisco 3750 Switch stack.
All by performing a tcpdump on a host without a report, I discovered that he was under the bombardment with ethernet frames for the MAC address of a computer virtual located on a host across the data center. After a few brief troubleshooting, I discovered that I was able to stop those erroneous frames by disabling NETWORK adapters on my VMWare host group.

I believe that in my situation when ESXi is configured to use two network cards to all frames received on vmnic0 and retransmits them on vmnic1 and vice-vesa. I experienced these symptoms when ESXi is configured for failover with an active adapter and adapter mode standby and I also experienced the same symptoms in the following load balancing configuration.

Symptoms: some time after activating the load balancing, all frames Ethernet for the MAC address of a virtual computer on the affected host are broadcast on each switch port in the entire data center.

Steps to reproduce:
(1) implementation below configuration.
(2) unplug the ethernet cable connecting vmnic1 and switch1 port gi2/0/4
(3) run the host 1.1.1.1 EI - n - q tcpdump on any machine physics linux in the data center (don't even have to be connected directly to 1).
Confirm there is no packet seen with the IP address of 1.1.1.1 destination
(4) plug the cable between vmnic1 and switch1 gi2/0/4 port ethernet
(5) wait 60 to 120 seconds
(6) watch a burst of frames ethernet with the destination MAC address of the VM (which owns 1.1.1.1) in the output of tcpdump

I apologize for the delay in my response.

Unplug physically 2 cable NETWORK card on the host and configuration mirrored port on the switchport to 1 NETWORK adapter of the host, I have been able to confirm that the host VMWare issues guides on NIC1 with a destination MAC address of one of its own VM.

After carefully reviewing the captured data, I noticed that the destination frames wrong "02:bf:cb:50:a2:76" MAC address actually belonged to "Local Area Connection 1' one of my Windows 2003 Server WHAT VM installed on the suspected host.

Dig a little deeper, I discovered that this virtual NETWORK card is presented to the operating system as
Name: Local 1 network connection
"Type: VMware Accelerated AMD PCNet adapt."
MAC: 02-BF-CB-50-A2-76

But the configuration of the virtual machine in vCentre is
Name: Network adapter 1
Type: Flexible
MAC: 00: 0C: 29:fa:e8:83

Note the different MAC addresses.

Digging a little further I discovered that Windows 2003 server has configured on "Local 1 network connection" network load balancing and NLB is the cause of the altered MAC address.

Rather than to investigate further I have just placed a load balancer linux before the server windows 2003 cluster and that you turn off NLB.

But I suspect that there is still a fundamental problem in the Virtual Switch VMware with how he learns the MAC addresses of the virtual machine is using flexible vNIC. In particular, with a virtual machine that uses a form to override the MAC address such as that used by NLB.

Muse CC 2014 slideshow Horizontal Scrolling Thumbnails (Possible?)

Good afternoon Muse Forum: my name is Ira Bitner NYC U.S.A.
How are you? I have a question regarding slideshow and thumbnails in MUSE CC 2014.
Is Q: in Muse possible to have a slideshow with thumbnails scrolling? In other words is it possible to build a slideshow where, for example, maybe 30 thumbnails are used, but only 5 or more are visible in a horizontal row at hand (image of 'Hero') and when the user clicks on an arrow the advance of thumbnails horizontally to the left which brings the new group of tiles that have been 'hidden' on the horizontal line of origin? This allows the site contains many thumbnails that can "hold" on the page and at the same time does not cause additional thumbnails to be stacked vertically all on the same page at the same time view?
It is a very popular way of showing a slide show that advance images. I spent all night and hours and hours of searching Muse videos, entire web tutorials in the forums, and have not been able to find a way to achieve this type of slideshow. I would have thought that the real slideshow widget, it would have been very obvious if it was actually possible to Muse. Help, please. If you need any Web site link as an example of the progress that horizontal thumbnail slideshow, I'll add one, but it is very common, and I can't believe that Muse would not allow it to build. Thank you for your time and and clearly - that someone might throw on this for me.

You can try to use the compositions, click slide show in the composition.

In the target composition container insert the slideshow and as game slides, create different slideshows for containers of different composition.

It would have a similar effect.

Thank you

Connect with independent switches vSwitch

Hi all
I am a newbie in VMWare and really not had in networking. Need your suggestion kindly for our VM infrastructure plan.
Here's what I have (or will have):
I create a small cluser (2 ESX, each with 6 NIC host). There are 2 stacked Cisco 3750 and stacked 2 4524GT Nortel on our farm in GE switch. Up to now, we have 6 virtual machines, but we intend to put all the servers the VM infrastructure.
That was my previous plan:
I did some research in the documents of VMWare and BBS. I plan to ESX hosts connected to Cisco units, their link to GE in 2 units of the evening. Configure NETWORK adapters, port channels, load balancing, etc...
An incident has changed my mind. A month before our network, group support updated nortel switches firmware. It's a nightmare. The Nortels 2 were dead after the upgrade. Had to pass all connections to the server of Nortel to Cisco and roll after that the call of Nortel has been set.
My question:
So let's say that sometimes the stackable switches will be dead together. Yes, I can connect an ESX with Cisco and another with Nortel. When stacked Cisco or Nortel is dead, we have yet another host working with switches lived. But I can connect an ESX with Cisco and Nortel? It seems more stable, isn't she?
For example, I intend to use the 4 NICs for production and other for SC and VMkernel network interface cards. The production of 4 network cards are rising in a vSwtich. Failover and load balancing works when I connect nic0 / nic1 with Cisco and nic2 / nic3 with Nortel?

My recommendation:

Configure NETWORK adapters, port channels, load balancing, etc...

Forget it. No team, no port channel. Just configure the uplink as junction ports ports and set the VLAN on the virtual port groups. VMware ESX (i) (with standard vSwitches) performs Round Robin load balancing based on the original default virtual port code, which is sufficient in most cases. With dvSwitches, you also have an option to configure NIC database load. In both cases you can use ports on all physical switches without having to think about making active configurations / standby at all.

On the beat of the heart. Usually, I connect the Service Console to a vSwitch with 2 physical uplinks, each on a different network card and everyone to another physical having redundancy switch. What I actually do is to put the Service Console and VMotion that vSwitch and configure groups of ports for active / standby to ensure that each of them uses a dedicated NETWORK adapter unless there is a network outage.

You must also consider switching to (installable) ESXi as ESX will be greater in the future. If you do not need to install agents on hosts etc, the only change will be that you will not have a "Service Console" more. For communication and management, you will have a «VMKernel network management» instad
