Catalyst 3560 vs. Catalyst 3750 - 24 and 48p. 10/100/1000

I need some help in positioning the Catalyst 3560 against the Catalyst 3750 - (only 24 and 48p. 10/100/1000) Switches.
Under which circumstances should our customer buy 3560 and what are the arguments for the 3750 solution ?
What are the major differences ?
Thank you very much for your help !
Regards,
Cope

CAT3750 series support stackwise technology while 3560s do not. This is the main difference between 3560s and 3750s. The switching architecture between the two is very similar. Stackwise comes with lot of advantages. You can find more on CCO at

Catalyst 3560 vs Catalyst 3750

I need at least a 12 port 10/100/1000 and a 48 port non-POE 10/100/1000 switch that support
unicast and multicast. I'm not sure if a 3560 model or a 3750 model would be better. Does someone know the main differences between the two? This in in a school enviroment.
Thanks
Dave

For me, 3560 is newer and more cost-effective model. Both of two series can fulfill such port requirement but 3560 is cheaper, unless you have policy to use 3750, otherwise, I will prefer 3560.
Below is the product info. of both sw :

http://www.cisco.com/en/US/products/hw/switches/ps5023/index.html
And you can use the switch solution finder to select the right one. But I can't access it, I don't know it is my PC problem or the web problem. Please try it.

Catalyst 3560 24 port-PoE switch powers on but no STAT LED and console not responding

I rebooted my Catalyst 3560 24 port PoE switch and when it turned on only the STAT LED went green the other LEDs are off. I get no response from the console port using putty and the cable I used before this happened. I tested the cable on another switch and it works fine with putty. What can I do with this switch?

This unit was purchased before I came to our company. There is no support or maint contract. I'm sure the unit is several years old...we'll call the vendor and see what they'll do..not expecting much.

Catalyst 3560 and MGBIC

Hi,
I would like to know if the MGBSX1 and MGBLX1 are compatible with Catalyst 3560 SFP ports (WS-C3560G-24TS). I'm looking to directly connect my fibers to my switch, but I couldn't find out the difference between MGBICs and GLC-LH-SM=, for example. Cause MGBICs are really, really cheaper.
Thanks,
Caio.

Yes the MGBIC is cheaper then the GLC-LH. Although made by the same group of manufacturers Cisco has inserted an IDPROM algorythm to check. The MGBIC doesn't have this value.
Cisco has put a stop to the enterprising practice of purchasing 3rd party (and cheaper) modules to be used in their equipment and then ring up TAC for issues with it.

3560 and 3750 - Question about 10/100/1000 ports

I am researching several Cisco products to recommend to a customer. I was wondering if the 10/100/1000 ports at a 3560 switch, will provide gigabit bandwith on each port or if the bandwidth is shared among several ports. The latter is how a 48 port 10/100/1000 line card would behave on a Cisco 4500 when, depending on the card, the gigabit bandwidth will be shared among 4 or 6 ports at a time.
What about 10/100/1000 ports on a 3750?
Thanks

The new Catalyst switches/modules such as the Catalyst 6500/6000, 4500/4000, 3550, and 2950 support 10/100/1000 Mbps negotiated Ethernet interfaces or ports. These ports work on 10Mbps, 100Mbps, or 1000 Mbps speed based on their connection to the other end. These 10/100/1000Mbps ports can be configured for speed and duplex negotiation in the same way as 10/100 Mbps ports on CatOS or Cisco IOS Software-based switches. Therefore, the configurations given in this document for 10/100Mbps port negotiation applies to 10/100/1000Mbps ports as well.

Catalyst 3560 - performance issue

hello,
could someone provide me with info or link to document about maximum performance rate for routing of WS-C3560-24TS (24 10/100 + 2 Giga SFP) switch with configured desktop routing sdm template. Switch should serve as L2 for traffic coming from some interfaces, and as L3 for traffic coming from some other interfaces. In general, I am interested about info about performance comparison when different sdm templates/scenarios are deployed.
thanks in advance,

Connection of LC/APC fiber patch cords to Cisco Catalyst 6500 $ Cisco Access 3750 Switches

I have an LC/APC fiber patch cord infrastructure and I want to connect it to Cisco Catalyst 6500 & Cisco Access 3750 Switches. what type of transceiver should be used?
I read a note on Cisco website stating the following for Cisco SFP+ transceivers:
Note: "Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section"

Thank you, but my question is that I have a single mode fiber patch cord with LC/APC connector while cisco stating a note that only use LC/PC or LC/UPC type of connectors with SFP+ transceiver.
So what type of transceiver should I use to connect LC/APC patch cord to cisco switches? Is there another type or SFP+ still can be used?

Dynamic VLANs on a Catalyst 3560

Hello,
I'm looking for a solution that would enable me to assign users to a specific VLAN based on MAC address. I'm using a Catalyst 3560 switch. Is there something similar to VMPS that would allow me to do this? I would like to run VMPS, but it looks like you need a VMPS server (catalyst 5000) to do this. Any help would be appreciated. Thanks!

They can be is the answer; however they don't have to be. Not all Cisco IP Phones have an 802.1x Supplicant (I assume you are using Cisco IP Phones and Voice VLANs?), only the newer ones do I think (7941, 7961, 7970 etc). I think by default the Voice VLAN on the access port does not do 802.1x authentication so the Phones bypass any 802.1x authentication.
If you have non-Cisco IP Phones then there are some more hurdles like VLAN detection and depending on the Vendor this can be achieved in a number of ways. It's should all be possible though.

Media Converter & Catalyst 3560 giving me headaches

Physical location 1 is connected to Physical location 2 with fiberoptic cable.
Location 1 fiber is terminated at Catalyst 3560.
Location 2 fiber is terminated at a media converter, so that the fiber link should be able to transparently be connected to a gigabit ethernet by rj45 cable.
The two fiber cables at each end is the same (62.5/125) - all is multimode fiber, and the gbic in the catalyst, and the media converter are both 850 nm.
On the Catalyst gbic where the fiber is, no link.
On the media converter there is link on the rj45, but no link on the fiber.
I cant seem to get what could be the problem.
The media converter is a tp-link mc200cm, which is gigabit, as well as the gbic module in the catalyst.
At first I bought the wrong tp-link (mc100cm - wavelength wrong) - however, on that, the fiber link lights (but very quick flashes only).
Any help, pointers oir the like would be greatlty appreciated!

It would seem the two devices should be compatible; both 850nm, short-reach interfaces and the instructions for the media converter shows a single-ended configuration. In the past, others have found that some media converters only operate in matched pairs; typically meaning they are not 802.3 compliant on their fiber links.
Have you confirmed that the fiber connectors are clean and the fibers are routed to the correct ports (Tx to Rx, and Rx to Tx)? Are the ports set on both devices for Auto speed and duplex setting? Have you tested the fiber links to ensure they are good? If you loop the fiber cable on the 3560's GBIC from Tx to Rx, can you get link? At the media convertor end, disconnect the fibers and connect the fibers together; does the 3560 show link? If you loop a fiber at the media converter's optical ports, does the media conv show link?
Let us know. Thx!

SRW224G4P uplink to catalyst 3560 switch trunk

I have many SRW224g4p switchs,and I use a catalyst 3560 for a core switch.
The SRW224g4p uplink to 3560 switch
What can I config the port of the 3560 to SRW224g4p(Their are many of vlans in my network)
and config the port of SRW224g4p to 3560's port
ps:config trunk port problem

Hi Wei,
Are you working on the Linksys SRW224G4P or the replacement Cisco (300 Series) SRW224G4P-K9-NA? Can you attach your 3560 Truk Port Configuration along with the VLAN Configuration?
Thanks,

Catalyst 3560

I am considering adding a Catalyst 3560 to my network to run IP phones. I am a small business owner and not too hip on switches. I have about 15 phones to add to our existing network. I am looking at just getting a 24 port switch to handle the phones and keeping my data on an existing switch. The other option is to buy a 48 port switch for all of my devices. What do I need to consider?

It comes down to whether or not you want to put all your eggs in one basket. It is a matter of trade-offs:
One switch:
- easier managability
- only one device to maintain
Two switches:
- if one goes down, you don't lose everything
- you could spread your critical devices over the two
- you now have two switches to maintain and manage
There aren't any clear advantages either way, it's your call really...

Catalyst 3560 routing for network boot

Hi guys,
I'm a Cisco noob so please forgive me if I'm asking stupid questions :)
I have a Cisco Catalyst 3560 in my lab and it's currently a single VLAN set up with all 48 interfaces in it. The switch receives static IPs from the router and as far as I understand is not doing any routing by itself. I'd like to run my own tftp server available only to the servers on this switch (for network boot).
So what I probably need this switch to run is some kind of an internal network i.e. 10.10.2.0 so I'd be able to reach the servers on this switch both via an external IP xxx.xxx.xxx.xxx and an internal one say 10.10.2.3 during the PXE boot.
So how should it be done and is it possible at all?
I hope I'm making myself clear and you got the idea. Please ask if you don't. :)
BR,
Paul

For example, if I start the security wizard and choose a single interface (FastEthernet6 in this case) to block port 25 on I get this config:
Restricting Applications.
Creating ACL SecWiz_Fa0_6_in_ip based on provided criteria
Creating VLAN Map SecWiz_Vlan1
Applying VLAN Map
Applying VLAN Map SecWiz_Vlan1 to Vlan1
and when I click on Show CLI sequence:
Cisco1(config)# no vlan access-map SecWiz_Vlan1 10
Cisco1(config)# no ip access-list Extended SecWiz_Fa0_6_in_ip
Cisco1(config)# ip access-list extended SecWiz_Fa0_6_in_ip
Cisco1(config-ext-nacl)# deny tcp any any eq 25
Cisco1(config-ext-nacl)# permit ip any any
Cisco1(config-ext-nacl)# exit
Cisco1(config)# vlan access-map SecWiz_Vlan1
Cisco1(config-access-map)# 10 match ip address SecWiz_Fa0_6_in_ip
Cisco1(config-access-map)# 10 action forward
Cisco1(config-access-map)# exit
Cisco1(config)# vlan filter SecWiz_Vlan1 vlan-list 1
after I apply the changes port 25 gets blocked on the entire switch. I believe it will be the same for what I'm trying to do now.

Installing c3kx-nm-10gt module in Catalyst 3560-X-24T-L

I am attempting to install a C3KX-NM-10GT network module into my Catalyst 3560-X-24T-L switch. Any time I do this, the interface fails to operate, and the web-based status interface fails to operate correctly until the system reboots. When I connect using the CLI, it sees the 10Gigabit interfaces, but they will not operate when I connect a device. Utilizing the shutdown and no shutdown commands does not seem to affect the interface.
Current software version on the switch is 15.0(2)SE7 IP Base.
Any thoughts would be appreciated.

Assistance Disabling BPDU Guard: Catalyst 3560 CG

Good Morning Guys,
Here's the situation:
Configuring cisco wireless bridges - every time I get both devices up in my wireless controller, the port my root bridge is connected to on the catalyst 3560 CG switch gets disabled with the following error:
"SPANTREE - 2- BLOCK_BPDUGUARD: Received BPDU on port, *** with BPDU Guard enabled, disabling port."
I've done some research on BPDU Guard and I've tried applying the following commands to no avail:
1. errdisable detect cause bpdguard shutdown vlan (global and config mode)
2. spanning-tree bpduguard disable (configuration mode at the interface)
any assistance to prevent the port from shutting down would be greatly appreciated.
Christian

You should double check the interface configs on both. It is shutting the port down because it is receiving BPDUs. This could be cause your switch port is configured for access but the WLC is configured as trunk...
