2GB EtherChannel Cisco 3750x-Cisco 2960S

Hello,
Im trying to setup an EtherChannel between my 3750 stack and my 2960S stack.
I have 2 3750x in stack form. (2 switches).
I have 4 2960s in stack form. (4 switches).
I need to create a 2GB channel between them. My core is the 3750, and my 4 stack 2960s is on another floor, so I want to create a 2GB pipe between them.
I know you can create a PO between them, but what I want to do is create a 2GB pipe between them that run at the same time, active on both 1GB ports.
Is that possible and how? This is my current setup so far:

Arent there different kinds of etherchannels you can setup? for LACP...
I thought you can setup redundant, passive passive, passive active, etc. How would I do that.
Thanks...

Native VLAN on Cisco 3750x vs Cisco 2960S

Hi,
I have a scenario where I connect my Cisco switch 2960s with Cisco router 1941 as photo below
My question is when i connect router with cisco 2960s I config interface Gi1/0/1 as a trunk. everything work fine, I can ping from router to switch(172.16.29.2).
But when I changed to cisco 3750x, i config interface Gi1/0/1 as a trunk, it cannot ping from router to switch(172.16.29.2). But after I add native vlan 30 on interface Gi1/0/1 I can ping from router to switch (172.16.29.2)
Any idea why ? is there any different of native vlan on cisco 2960s and 3750x ?
Thank you for your kind answer
John

Hi John
It seems for me that the 3750 is doing what it should do, if the router do not have subinterfaces and dot1q, it will send traffic without dot1q tag, and the 3750 will drop these packets because they arrive without a tag. That's why native vlan fixes the problem.
The 2960 should work the same way that 3750 do, so I wonder if there is some differences in the config between the switches.
Can You share the config for gi0/1 on the router and also the switchportconfig for both switches.
Also a "show interface gi1/0/1 switchport" for both switches.

Calculate? Calculate for wirespeed/line-rate? If the latter, take all the port bandwidths, and assuming they are duplex, double for necessary fabric bandwidth. I.e. 48 gig ports would need a 96 Gbps fabric. Take all your port bandwidths, and allow 1.448 Mpps per gig (for minimum size Ethernet packets), i.e. 48 gig ports would need 69.5 Mpps. Once you have required fabric bandwidth and PPS, you can compare to vendor's specs.

DAC Cable to Cisco 3750x

Connect cisco 3750X and Dell N4032F

Hi,
I need to connect 2 diferent networks (192.168.x.x vs 10.44.x.x). this connection will be temporal because network 192.168.x.x will be migrated to 10.44.x.x.
On one side I have a Dell N4032F (L3) and on the other side a Cisco 3750X. What I need is just visibility between them? Wich is the best way to do it.
Thanks

Hi,
On the 3750X, you need to configure the IP address on the interface connecting to Dell.
example:
config t
interface gix/x
ip address 10.44.1.1 255.255.255.0
no sh
Not sure what you need on the Dell side.

Cisco 3750x switch. Turning off a port at night

Hi everyone,
I have a question regarding power management for the Cisco 3750x Switches. Is it possible to power down switch ports
automatically at a specific time and if so how. I would like several Ports to be powered down between 2 and 3 o clock at night.
Can anyone tell me how i can realise this? (these switches have Energie Wise capabilities)
I hope to hear from you soon.
Thanks in advance!
Kind regards,
Wouter Platteeuw

few things to try:
Go to your email setup, go to the account in question, go to filters, Check the box that says "do not forward messages to the device" Set this back to the default if this doesn't work.
Something else: try using the blackberry firewall
http://btsc.webapps.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB23877
I think this will block all email though, but you can take a look at the options.

Unable to hard code the ports of cisco 3750x series switch

hello,
I have tried with hardcode to 1000 7 Full on the ports which are connected to another switch.
After changing the port to auto from one side of the switch port came up. Is there any solution to make port up when both sides are hard coded to 1000 & full duplex.
Simple Words:
Switch 1 --> Switch 2 --> Hard coded to 1000 & Full --> Down.
Switch 1 --> Switch 2 --> Auto on one end to Switch 1 --> Up.
Switch model:
Switch 1 Cisco 3750x (Gi Switch)
Switch 2 Cisco 3750 (Gi Switch)
Regards,
Ezra.

Yes, it's possible without a straight through cable, enable auto/auto both sides. Otherwise you'll need a cross-over cable.
BTW, if your standard is hard coding copper gig ports, for speed and duplex, you might consider bringing your standard up to date. Copper gig standard went much further in how auto/auto is supposed to work. By disabling auto/auto, I believe, you're also disabling some error monitoring too. Generally, all the major players, e.g. Cisco, would recommend auto/auto for copper gig Ethernet.

Cisco 3750X -- 10G uplink - Can be used as access port?

Dear All,
I have small question, I am planning for Cisco 3750X with 10G SFP+ service module. I want to know that whether it can be used as Access Ports connecting to server as this is mostly used as uplink port.
Thank You,
Abhisar.

Well if you want to connect anything with 10g to a 3750X, you're limited to using a module with 10g ports.
Other than 10g capability on some module cards, something to note, the module ports, I believe, are supported by larger buffers (including the gig module ports).
As the others have noted, you can use any port for any purpose. However, if you connect a server to a 10g port, be aware you might start to see drops on your other host (gig) ports as the server will now be able send faster than the host port can receive data. To minimize this, you might either disable QoS on the switch (providing maximum buffers to all egress traffic) or you might need to tweak buffer resource settings (the default settings often drop some packets, when there are bursts, of default marked packets).

Is power supply 3k-X 715W AC hot swappable on Cisco 3750X?

Is power supply 3k-X 715W AC hot swappable on Cisco 3750X?
Thanks
Diego

Sorry, found the answer http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/hardware/installation/guide/3750x_3560x_HIG/HIGFRU.html
The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing mode, removing a power supply causes powered devices to shut down until the power budget matches the input power of a single power supply. To minimize network interruption, hot swap the power supply under these circumstances:
–The switch is connected to an XPS 2200 and sufficient power is available.
–The switch is in StackPower mode and sufficient power is available (Catalyst 3750-X only).
–The switch is powered by other switches in a power stack, and no active backup is in progress.
For the switch commands for displaying the available power budget, see the Catalyst 3750-X and 3560-X Software Configuration Guide.

Cisco NAC, Cisco ACS, Microsoft NAP, Anti Virus

Hi,
I'm doing a research on the Cisco NAC (without the appliance) concept and I would like to ask the following:
1. Securing network access - Needed products are Cisco ACS and Cisco access devices (2960, for example). The feature needed is NAC Layer 2 IEEE 802.1x. Is this correct?
2. Forcing Windows PC to download OS patches according to company policy. Needed products are Cisco ACS, Cisco access devices, Cisco Trust Agent and Microsoft NAP (Network Access Protection)? Is there a way to do this only with Windows Server (not using NAP)?
3. Forcing Windows PCs to update Anti Virus software. Needed products are Cisco ACS, Cisco access devices, Cisco Trust Agent and Anti Virus server? Is this correct?
Please, give me some advice.
Thanks in advance,
Mladen

Thanks for the reply, but still I am a bit confiused (would you please try to answer the questions?):
1. Securing network access - Needed products are Cisco ACS and Cisco access devices (2960, for example). The feature needed is NAC Layer 2 IEEE 802.1x. Is this correct?
2. To force update of Windows patches, do I need a NAC appliance (I can only install CSACS)?
3. To force AV updates, do I need a NAC appliance (I can only install CSACS)?
I refer to
"Implementing Network Admission Control Phase One Configuration and Deployment";
"Network Admission Control Software Configuration Guide - Information About Network Admission Control".
Thanks in advance,
Mladen

Configure Cisco Mediatrace, Cisco IOS IP SLA, and Performance Monitoring

Hi all,
I am implementing Cisco Prime Collaboration to monitor the quality of the VoIP call.
I am following all the steps that I have to do to accomplish this task at this link:
http://docwiki.cisco.com/wiki/Setting_up_Devices_for_Prime_Collaboration_Assurance#Configuring_Unified_Contact_Center_Enterprise_Devices
And now I am arrived on this step:
Configure Cisco Mediatrace, Cisco IOS IP SLA, and Performance Monitoring
Not all the Cisco devices that I have on the network are "Mediatrace, IP SLA and Performance Monitoring" capabilities. The core switch is one of them.
What will happen if some devices are configured with these capabilities and some are not?
Are the data provided from Cisco Collaboration still reliable?
Thanks in advance.
Luigi

I can't see a reason why the 2 features won't work together. The 2 features will work just fine with each other.
Unfortunately there is no sample config with both feature in the same document, but it will work just fine.

Monitoring for Cisco UCS/Cisco Catalyst/EMC VNX/VMware environment

I am not sure whether this is the right place for this post, but I am giving it a shot anyway.
I am looking for a monitoring solution for a Cisco UCS/Cisco Catalyst/EMC VNX/VMware environment and I cannot seem to find 1 product that does it all.
Do any of you Guys have experience with a such product?
thanks...

I have used PRTG for Cisco Routers/Switch, Vmware and with Cisco UCS. As for the storage part I'm not sure.
I recommend prtg because its user friendly and web based management.
