Cisco Switching/Routing :: X4648-rj45V+E Module Not Forwarding Frames / Packets In 4507E Switch?

Mar 26, 2012

I have a problem with x4648-rj45V+E module, which is not forwarding frames/packets in my 4507E switch. I have done the diagnostic and the module test is passed. When i try to ping from one PC to another in the flat network, icmp is not forwarding. Even i cannot see the mac addresses in the mac address-table. But i can ping to my management port in the sup module?

Cisco Switching/Routing :: Forwarding IEEE 802.3 Raw Packets Through 2960G Switch

Dec 5, 2011

I have a requirement to monitor downstream data feed from a remote site and feed it to multiple destination devices for recording.  The source data will be fed into a port on a Cisco 2960G switch then, using the monitor function, be forwarded to multiple interfaces.   This works fine for normal Etherent II traffic.  We tried a test using a device that generates IEEE 802.3 Raw packets ('type' field is used as a 'length' field) but found that while the traffic appeared to be accepted by the input port with no errors it was not forwarded to the destination ports, even when using the monitor function.  I did try the 'encapsulation replicate' feature with no luck.  It does not forward these packets even if I set all the ports into a common VLAN and let the switch just perform a normal switch function (non monitor).
 
if it is possible to get the IEEE 802.3 raw packets to pass through the switch and if it is, how to or what I need to do to make it work?

Cisco Switching/Routing :: PoE Switch Ports Stops Supplying Power On Cat 4507e

Dec 11, 2011

i  recently deployed cat4507e switch along with  3 nos of WS-X4748-RJ45V+E - 48 port gigabit PoE modules. I am using polycom IP560 phones.
 
I am facing issue of some switch ports (randomly) stops supplying power to phone at random time. So far there are about 4 incident and i have been plugging those connection to different - usused ports.  I am planning to RESET the switch module during weekend and i think it might fix issues with those ports.
 
But what would be quick and easy way to fix this issue when the issue is faced? How/what to check on switch port interface wrt to power? If switch module is falling short of overall power requirement, is there a way to boost the power?

Cisco Switching/Routing :: To Use DFC3 6500 For Forwarding Packets

May 31, 2012

From everything I read it seems like DFC is for forwarding packets.  When I hear packets I think of layer3.  If my 6500s are just being used as a big layer2 only switch do I need a DFC?  I am being told the 6500 looks at the layer 2 frame and the layer 3 patch header information before forwarding the frame.  How true is this?

Cisco Switching/Routing :: Full Switch Outage After Enabling Jumbo Frames On Nexus 5010

Nov 22, 2011

I attempted to enable jumbo frames on a Nexus 5010 (NX-OS version 4.2(1)N1(1)).  I created the policy map below and lost access to the switch.
 
policy-map type network-qos jumbo
class type network-qos class-default
mtu 9216
 
After recovery I see from the logs that all vlans and interface were suspended.  I've attempted to look for reasons for a compatibility issue but I am unable to find what is checked and what could have been incompatible.  The other troubling thing is the adjacent switch suspended its interfaces too but no change was done there. What I need to look out for so that this does not happen again?

Cisco Switching/Routing :: Catalyst 3560 Switch Won't Forward Packets To Or From MAC Address

Aug 9, 2012

I have some Ethernet-connected cameras that all have the same Ethernet MAC address FF:FF:FF:0A:0A:0A. They were originally designed to directly connect to a Windows PC, but they can also connect through a simple unmanaged switch.A Catalyst 3560 switch won't forward packets to or from anything with that MAC address, at least not by default. Is there a way to convince the switch to do so?
 
It was my hope to replace the dedicated connections we have for these cameras with a separate VLAN for each camera, and switch them through our existing switch network. Given that all of the cameras use the same MAC address, putting them on the same network is out of the question, but different VLANs, where the only two devices on each VLAN were the camera and the PC that uses it, would be fine.
 
The switches run IOS 12.2(55) SE through SE3. I learned the camera MAC address from the PC's ARP table while the camera software runs; it turns out the cameras don't have a full IP stack either and don't even do ICMP.

I want to be sure that these are the only needed comands and that they won t generate any disruption.

Cisco Switching/Routing :: Setting Up Switch Module On 2951?

Sep 18, 2012

I'm trying to set up a 2951 with a 24 port switch module. I want the ports to act similiarly to the ports on an 881 router - where I assign the VLANs on the router and I set the VLANs to the switchport interfaces.I would like to be able to create the VLANs on the router portion of the 2951 and then, enter the switch module and configure the Ports to the VLANs but, how do I logically connect router to the switch? Is it an internal logical interface - meaning how are the VLANs getting from the router to the switch?

Cisco Switching/Routing :: 2811 With 16 Port Switch Module Configuration?

May 12, 2013

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
 
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.

Cisco Switching/Routing :: VSS Switch Got Hang After Inserting 6708 Module?

Jan 11, 2012

We having a VSS switch (9 slot chasis) with ios "s72033_rp-ADVENTERPRISEK9_WAN-M), Version 12.2(33)SXI4", slot 7-9 are currently free. We wanted to install WS-X6708-10G-3C module on slot 7. Once we installed the module it didnt come, after waiting for 15-20min again we removed and inserted, but module didnt come up and we could see following logs on the console:

Afer some time VSS switch didnt response to console commands and all the users in access switches were not able to reach the gateway (VSS). Then the problem disappeared once we rebooted both the switches in VSS.why the VSS switch become non-responsive?

Cisco Switching/Routing :: How Switch Module Works In 2911 Router

Sep 4, 2012

how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.

any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.

Cisco Switching/Routing :: Replacing A Dual Supervisor Module In A 6513 Switch?

Jun 18, 2012

I have a supervisor blade, (VS-S720-10G-3C), in a 6513 that is faulty and needs replaced. Do I need to replace the IOS on the new supervisor blade to make sure it is the same as the IOS image that is on the Active supervisor module, or will it synchronize automatically?
 
In the synchronization process, the active supervisor engine checks  the  standby supervisor engine run-time image to make sure that it  matches  its own run-time image. The active supervisor engine checks  three  conditions:
 
#
•If it needs to copy its boot image to the standby supervisor engine
#
•If the standby supervisor engine bootstring needs to be changed
#
•If the standby supervisor engine needs to be reset
 
 I was reading the above documentation that mentioned the active supervisor should copy the image if it detects a newly installed standby supervisor blade with a different image, is this correct or was it referring to synchronizing the configuration file?
