Cisco Switching/Routing :: 3560X Multicast Traffic Should Not Appear
Feb 18, 2013
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.
I am trying to resolve a situation where we need to send multiple (2 atleast) multicast feeds from a source to our multilayer switch (3560x).
The problem with the source is that it can only send a feed to a single switch at a given time. It can not send 2 (identical) feeds to two 3560x devices (on 2 different subnets/vlans). I was wondering if i could make the two 3560x devices appear as 1 device (using virtual chassis system or a similar feature). I am running ip services IOS feature set (c3560e-universalk9-mz.122-58.SE2.bin).
Attached setup i am planning for testing multicast output from different vendors using VLC and STB. This Setup made to test the picture quality between the vendors at the same time on the multi viewer screen.
1) Only a 2960 Gig port switch with only one L2 v lan with IGMP snooping enabled. In this scenario where Source and receivers are in the same L2 v lan ( no L3 interface is involved) hope i would able to test all the multicast sources with out any additional configuration on the Cisco switch.
I have configured multicast(ip pim dense-mode) on two 2911 that are connected by a Multilink( 3 Mbps) Wan connection.The configuration works fine for awhile and sometimes all day but at some point one of the Multilink interfaces stops passing multicast traffic.I perform a SH Multilink 1 on the interfaces and one show multicast packets incrementing and one does not, it just stops.The problem acts like there is a buffer that gets full and after that happens it just stops working.
I am having trouble getting some multicast traffic across a link. I have a 3750G setup, with IP routing and IP multicast routing, between two laptops. This will eventually sit between two networks that cannot be physically connected to each other for security reasons. I have static joins on the ports but cannot see the multicast traffic on the receiver. I am attaching the latest config. The sender(10.10.4.2) sits on gi1/0/24 and the receiver(10.10.3.2) sits on gi1/0/1. I am using VLC to test this and it will connect if I point the receiver to the address of the sender, but will not receive any multicast. The multicast traffic is not making it to the 10.10.3 side, I used wire shark to verify that it was not making it across.
Multicasting. The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10. I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch. On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10. The 2960G switch has a workstation connected to it that needs to receive the multicasts. How do I configure the 6506 and/or the 2960G to process the multicast traffic?
I have two Catalyst 6506 in VSS mode with VS-S720-10G running 12.2(33)SXI1 IP SERVICES.I have two firewalls that communicate on to the other through a dedicated VLAN created on Catalyst 6506.
One firewall is able to ping the other one on this dedicated VLAN but if I send multicast traffic from firewall-1 I didn't receive it on firewall-2.I found a bug related to multicast issues on Cisco WS-C6509-E with VS-S720-10G. The bug ID is CSCtc59038.
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
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:

It would be so easy but failed to upgrade 3560X switch to ip services licence is bought and paid for mail and log from the CLI and tftp server attached
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?

if a connect to the switch via Internet Explorer or every other browser I can't enter configuration because I receive a screen as you can view in image below. And I can view those errors:

If I connect in HTTPS with IE8 in compatibility mode I view the image as in attachment with_https.jpg.
why Cisco make 3560x switches with Lan Base(no routing functions)? What happen if I load an Image L3, previously downloaded? my device lost the warranty? or it doesn matter?
I have a Cisco 3560X series 48 port PoE switch which im using to try to power a Axis Q6032E PoE+ PTZ camera that requires 25W of power. Although when I plug the camera into the switch it power as PoE Class 4 but will only assign the port 15.4W of power. I have tried going into the switch and manaually assigning the port to 30W of power but no luck. I have talked with the Axis vendor and they stated that Cisco does not turn on 802.3at protocol by default? This does not seem correct. I am running a single 1100W power supply as well. See output below. Gi0/43 is port in question.
Gi0/41 auto on 15.4 Ieee PD 4 30.0 Gi0/42 auto off 0.0 n/a n/a 30.0 Gi0/43 auto on 15.4 Ieee PD 4 30.0
I have a brand new 3650x switch that I was configuring via console and left it on overnight; this was friday night ( I forgot to keep the air conditioner on). When I returned Sunday afternoon and checked the switch I realized that the SYS and STAT lights on the front were not on, however the Leds on the PS module were still on. I powered it down and turn it on again but still there are no lights on the front. The PS OK and AC OK leds on the PS module are on but I noticed the leds on the two fan modules are not green or even amber; they are off.When I first turned on the switch I remembered distinctly that there were loud noice and if all fans were in overdrive mode for a few seconds then the went to normal. I'm not gettgin this loud noise phenomenom.
Is the CAB-C15-CBN - Cabinet Jumper Power Cord, 250 VAC 13A, C14-C15 Connector, supported on the Cisco Catalyst 3750X/3560X. I need to plug the switches into a UPS PDU, that requires a C14 plug.
Is it possible to to build a Layer 3 ether channel from two separate physical switches (layer3) that are trunked together?I know you can easily do this on a single switch and on stacked switches which I've done but in this case the customer have purchased two 3560X's which are not stackable yet want redundancy. The purpose of the etherchannel is to connect both switches to a private circuit provided by the hosted partner then route to the same setup in the DR location to different subnets.
I am trying to configure EIGRP on my ASA DMZ Interface - topology as follows: [code] The ASA is currently configured for EIGRP with the inside 3560x switch and passing routing updates properly.However, the ASA will not send/receive routing updates to/from the DMZ 3560x switch - the two devices do establish eigrp neighbor relationship. [code]
Is there a way to configure a VACL capture on 3560-x, we need more than 2 SPAN sessions. Feature navigator indicates that this feature is supported but it seems like it's not implemented in the IOS yet.
Are the power supplies on these switches interchangeable? I know the model numbers are the same with the exception of the /2 at the end if it. Customer wants it to have a dual power supply but not sure if I need to order a secondary powere supply or just another powere supplu from a spare switch.
The setup I currently have is a server attached via an etherchannel to a 3560x switch, which is connected to a pair of 5548UP's that are connected via vpc. The 5548's both have a single connection to 6500 series switch that does the layer 3 routing, the ports that connect the 5548 to the 6504 are trunk ports. The problem that I am having is that one of the 5548's can ping the server that is connected down stream while the other 5548 can't. While the local switch can ping the server, and other servers on the same switch in the same vlan can ping it as well. The vlan interface I am pinging from on each switch is on the same subnet as the server I am trying to ping. One other thing, Nexus #1 which can ping the sever has the mac address in its mac address table, while Nexus #2 doesn't. However I added the static mac entry to Nexus #2 and that did not allow me ping either.
I configured a Switch Cisco 3560X with a basic configuraction, My problem is that when I access Web interface by http://X.X.X.X an login after the image that I attached.I tried restore the default configuration, also tried with different navigator, chrome, Internet explorer, fireffox, safari, change laptop... and update the java client.
