Cisco Switching/Routing :: 3560X C3KX-NM-10G (SFP Link Is Not Working)?
May 12, 2012
I am trying to connect tow 3560X using a fiber cable (MM)I have C3KX-NM-10G in both switches (4 ports module)I have GLC-SX-MM in both switches (connected to G1/1)both switches are able to see & recognize the NM as well as the SFP.
Fiber Cable is tested Fiber Patch Cord also tested both ports configured as a trunks but also the switches are not able to see each other (even when I removed the trunks configuration from both of them)CDP neibour is showing nothing no links & no LED blink in any switch both switches are running c3560e-universalk9-mz.122-55.SE3 IOS?
There is no any other configuration in both switches.
I know that the C3KX-NM-10GT network module has two (copper) ports that support speeds of 1Gps or 10Gps. Could this module work with one port at 1Gb and the second port at 10gb simultaneosly? It's possible to work each port of the module with different speed (one port working on 1Gb mode and the other working on 10Gb mode)?
We recently upgraded the switch to which an old security device was connected. It worked fine on the old switch's FastEthernet port, which was configured for speed 10 and duplex half, as that is what the device required. The new switch is a 3560X with all Gigabit ports, but the security device's port, also configured with speed 10 and duplex half, does not connect properly.As a temporary test, we daisychained another switch that has FastEthernet ports, and the security device works again.Is there anything else that needs to be added to the configuration, when using Gigabit ports at 10/half?
I have a Cisco 3560X 48 port Ip base switch with v lan configured and ip routing. Ports 1 and 2 are in ether channel and routed ports to ASA and have their own network of 192.168.22.49/30. The ASA is configured with the same config for ports 1 and 2. The channel group ip address on the 3560X is 192.168.22.49/30 while the other end of the up link is the ASA and its configured with .50/30.
I have 6 v lans plus the one native v lan. They are all configured with ip addresses. Each V lan should be able to talk to one another other than DMZ v lan which is trunk and routed directly in the ASA. On the switch I can ping the IP address on the ASAs up link .50/30 but I cannot ping the ASA from any host on any of the V lans. My switch config file is posted below. The ASA seems to be able to ping any host in the VL ANS due to static routes that are in place. Why I'm not able to communicate to other v lans or even ping the ASA?

I have a 3750-x switch with module C3KX-NM-10G. In slots 1 and 3 I have GLC-T inserted, no problem. When I try to insert GLC-T into slots 2 or 4, I receive the log messages that are listed below. I can swap/mix and match different GLC-T's in slots 1,2,3, and 4, the SFP's are recognized every time in slots 1 and 3, and are never recognized in slots 2 or 4.
Slots 2 and 4 also double as the Ten Gig interfaces, which we are not using right now.Is there some trick to getting the switch to recognize SFPs in slots 2 and 4? [code]
confirm the C3KX-NM-10G module is hot-swappable.i have checked the cisco's website and it says " Although network modules are hot-swappable, we recommend installing a network module before powering the switch"
What steps i need to follow to install the module?
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:
A product I could have used a number of times is a expanded version of the C3KX-NM-1G device module. To include 2 or maybe 4 more SFP ports. From the layout behind the faceplate there is plenty of space which additional circuit boards could be placed, (which is used in the 2 port 10GB version). I don't need the 12 port fiber switch that Cisco has, because I need a few RJ45 connection at that location, which I would then have to buy additional Fiber to coper Gbics for a few connections where the switch is at. The reason I need something like this is I have a few locations which I get a main feed from the City fiber, then it gets sent out to a number of local buildings on my fiber. Maybe another option is to take the 12port switch, and have an option for 6 rj45 and 6 sfp connections.
I have a Catalyst WS-C3750X-24T-S with two power supply C3KX-PWR-440WDC, each of these power supply have two input to deliver 440 W, my question is: Can I use only one Input in each power supply to power up the switch?, I know that I dont going to get the total power of 440W, but the power delivers by the supply with one input circuit is enough to power up the switch condidering that the switch are not PoE and only have 24 ports?.
We have WS-C3750-24FS switches stacked supporting users on our LAN. I want take advantage of the netflow capabilities of the WS-C3750X using the C3KX-SM-10G card.
Would I be to see netflow data coming from the WS-C3750's if I stacked it with the WS-C3750X?
Also I read that the C3KX-SM-10G card would support a 1G SFP is that correct?
our network is spread over 15 floors and each floor we have 5-6 switches. we are planning to purchase cat3750-x 24 ps poe with C3KX-NM-10G network modules. Each floor has two up links to the core switch with single mode fiber and other being the multimode.Suppose if we are purchasing 75 switches do we have to purchase 75 C3KX-NM-10 G modules.? or can we limit our purchase with 15 C3KX-NM-10G sothat two uplinks from each floor can be made? since network modules are optional cost factor is invovled. Or any issue with stacking ? the SFPs will be LR and LRM MODULES.looking for an answer ? whether the new usb type console cable comes bundled with cat350x or shall we have to order separately?
For the c3kx-nm-1g network module it looks like it will take the standard sfp's for fiber but I need copper rj45 connections, is there a copper sfp for this?
I need to connect one sw3750E with two 3750X , with Uplinks at 10 GBps. My doubt is the next:
Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
Is it possible to connect 3750X with C3KX-NM-10G to X2 10G port on sup2t in 6500E switch.There is Cisco OneX Converter Module, but I could not find that it is supported on sup2t.
My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
I am working on the spreadsheet and it looks like this (Not totally filled):

i cant find any difference in these two devices when i am trying to compare throughput.I need upgrade our new POP and there will be around 4900 MAC adresses in VLAN 150 and 130 MAC adresses in vlan 200.Uplink is 1 gig routed internet connection and there is 14 downlinks to separate villages.i found a few differences for eg stack interface on 3750x but i dont need it.
I unpacked a new 3560x and went to put our standard code version on it c3560e-ipbasek9-mz.122-53.SE2. Everything seemed to upgraded fine but it won't boot to a console prompt. It seems like it loads the IOS image fine but can't get passed the Front-end Microcode IMG MGR: Programming device 0. [code]
We have a small site that has an Avaya voice switch connected to a c3560x switch.The avaya tech told us to set this on our ports to which the phone and the desktop are connected.
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:
If the 3560 or 3750 "X" series support GRE.I am pretty certain the older 3750-E does not support GRE (both in hardware and software)Was hoping the new super duper X series do. If not, it could get expensive
I have a 3560X switch with interfaces 36-48 on the same LAN. All interfaces are switchports. Hosts on 38, 39 and 40 are multicast senders: all sending to the same single multicast address. Hosts on 36 and 37 are receivers, having joined that multicast group. I created an SVI for the LAN and put it in ip pim passive. (That is the only PIM mode allowed for an SVI with my IOS.) Show ip igmp snooping groups shows that 36 and 37 are the only interfaces in this group. I attach a laptop to interface 42 and Wireshark, and the laptop is receiving the multicast traffic. The laptop does not join the group. I expect it would not see the traffic.
last week we have changed the connection of small town from licensed radio to direct fiber with clasic 1gig sfp.After that we have connected the new fiber , we can see 5 min outages of customer internet connection. If we are conncted on the same subnet anywhere on network, we can ping the customer all the time. But if we try to ping the customers public IP it is each 5 min for 5 min unreachable. I have tryed to sho logg in all switches but there are no mesasages. I just see, when comunication have lost, the MAC and IP of customer will disapear from routers ARP tabbel. What is going on?When i enter sho mac address-table i can see customers MAC address in all switches. There are exactly 5 min outages. 5min it runs ok, 5 min outage and it repeats agan.
I looks like the swith blocks the ARP packets from customers to their default gateway.The routers are connected to catalyst 3560x lan base ios, This switch is connected to another 3560x lan base ios and it is connected with fiber to ME3400 where are customers connected.
I have 3560X-24T-S switches with IP Services loaded at remote sites that I have been having troubles with. Originally, they had IOS 12.2(58)SE1 on them. I have up to four diverse paths via point-to-point microwave at the remote sites. The Microwave equipment is by Microwave Networks and is a Prodeus M series which Ethernet support. The original issue manifested itself as hardware loopback errors on some of the ports that were connected to the microwave links.
My experience in the past has been that when a hardware loopback error occurred it is usually a bad switch port. In this case however, if I disconnected all of the microwave Ethernet links and rebooted the switch and then connected the Ethernet connections to the microwave links again, everything works fine. No hardware loopback errors. That is, until the next switch reboot. Then the hardware loopback error would return. Interestingly, it would come back on different ports connected to the microwave links every time. So if a reboot was done without disconnecting the microwave Ethernet links the hardware loopback error would change from one microwave link to another after each reboot.
I then went through and read the lengthy release notes for IOS version 15.0(2)SE and found several fixes that I thought could fix my issue. So I downloaded it and updated a couple of the offending switches (not all of them were having this problem). After going through the second update required to resolve the 'open file error' that happens going between 12.2(58)SE1 and 15.0(2)SE the problem seemed to be resolved on the offending switches. So, I went ahead and updated the IOS on all of the switches with point-to-point microwave connections.
I now have one switch that was updated that is crashing and rebooting continuously when the Ethernet links for the point-to-point microwave are connected. Again, if I disconnect all the microwave links and reboot, it comes up fine ands stays fine when the microwave links are connected back up. It will work fine until the next reboot and then the crash and reboot loop starts over again. Below is a portion of the putty log when the crash occurs:

Im going to be ordering a new 3560X L3 switch (ws-3560x-48pf-s). We currently have a 3560 V2 switch and I've read it supports stacking, but looking at the back I just see a console port. Is there an extra card I have to get for this 3560V2 to make it stakable with the 3560X?
I was viewing the 3560x switch datasheet and i need network module C3KX-NM-10G. I have dark fiber with over 12 km distance to i guess i will be needing SFP EX for single mode.
I currently use L3 switches as edge routers to my WAN. I want to use a pair of 3560x switches with IPbase to provide a failover path to my WAN using HSRP at one location but had some problems testing the configuration. My plan is use a virtual address on the LAN interface (VLANx which port gi0/1 accesses) and the WAN interface (VLANy which port gi0/24 accesses). I want switch 1 to be primary since it will have an IPS attached to it, and switch 2 will be backup and used only when switch 1 or the IPS requires maintenance. On both the LAN and WAN sides there is no advanced routing going on, the various hosts just depend on the availability of their respective default gateways, so HSRP should be sufficient to provide a failover in either direction.
In my testing I got 1 or the other link to fail over but not the entire switch. What should my config look like to achieve failover of the entire switch in the event 1 or the other interface goes down, and fail back when the primary links are again available?
I am stuck at a very early stage in the configuration of 3560x switch. It seemed very unusual and that is the reason, I configured basic config for line con 0 with login local. And then I had just put "enable secret xxxxxx."
Now I simply logged out and when i tried logging in, it is asking for a username. Now the thing is that I had not programmed any username. I tried using just "." followed by my secret password, but it did not work.
we just got brand new 3560X with LANBASE license installed. Wanted to confirm with a "show license"
To my surprice (output below) I hav IP Services evaluation. I tried to test with an "show ip route" and "ip route..." in configuration mode with no success. How do I use the trial license?
