Cisco Switching/Routing :: Nexus 5010 - Only See Two 1 Gb/s SFP Fibre Modules
Nov 23, 2012
we have a old Nexus 5010 running version 5.0(3)N1(1)it is in a franckenblock(like frankenstein) ie . we bought the parts and create our own system design before VCE was created. He have since bought VCE V block for our production sites. we use the franc ken block to test before we migrate to the production v block 300 FIX the issue we have is the 5010 will only see two 1 Gb/s SFP fiber modules in the first 12 slots. All these slots are dual 1g/10G. If we add more than two, it claims not to see them. We tried swapping the sfp and using both sfg-GE-MM and GLC-SX-MM moduels, no difference at all 1g sfp are in the first 5 slots. only the first two slots are up.the others say "Link not connected" or "SFP not inserted"all five links are the same SFP and are plugged in other switches.the green link lights are on plugged in SFP, even when the CLI states they are not plugged uni tried both two types of 1 Gb/s SFP. sfg-GE-MM and GLC-SX-MM ,i move the sfp between slot 1,2 and 3,4,5. nothing changed,From "sh int brief" you can see that it can see the sfp ie they are all 1Gfrom "sh int status " it sees 1g but why does it say type 10G?why when i go to the "int e 1/5" and try switch port mode now, it can't mode and trunk at now there (;also how to i stop or clear EU51 %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 87%.i put as much info in the attached file as i could.
I currenty have a Nexus 5010 connected to a core 3750X switch stack in a VPC trunk using 2 1Gbps links. I want to move this link to 2 10Gbps links without losing connectivity. So I want remove a 1G link and move it to 10G and then once that's up move the other 1G link to 10G hopefully without losing connectivity. So the question is, can I have a 1G and 10G link between the Nexus and 3750s in the same virtual port channel without causing problems?
Our Data Center Switch (5010) rebooted itself today, underneath the captured screen

We are looking for some latency in our net and I am trying to check if our STP implementations is running correctly - we have a simple flat network here and no blocked ports here - just two nx 5010 which are interconnected with two uplinks.A remote site - mirrored setup - with 2 10G dark fiber connections - one for each nx5010 - is connection a DR site. I have split the two sites in two stp domains by enabling bpdu-filter on the vpc between the two sites.
I have been running wireshark on the local segment for some time and see the STP RST ROOT announcement every 2. seconds - this is probably normal ? I was looking for some alternate root negotiation packets which would cause the mac tables to be flushed.
I am not able to create more than 256 VLAN in Cisco Nexus 5010 switch. While creating I am getting "No VLAN resources available for VLAN creation" Details below -
Switch model - 5010 Software : NX OS 4.0 (1a)
Error Message: Nexus_5010(config)# vlan 417 ERROR: No VLAN resource available for VLAN creation.
I'm trying to create a vpc between a Nexus 5010 and Nexus 5020 switch. I recently upgraded the software so they are running the same version. I connect get a vpc link. Is there something wrong with my setup? Is a vpc between a 5010 and 5020 even possible? They are connected using a pair of Intel X520's in 802.3AD teaming mode. [code]
My monitoring tool is reporting alerts for high cpu utilization on Nexus 5010.Image is 4.1(3)N1(1) Only command supported on this code is sh proc cpu.The output of which does not really tell what is the current cpu utilization.How do i troubleshoot the cause of high cpu on nexus switches.
I am trying to configure get the QLogic 8240 card to work properly in ESXi 5.0. I want to be able to send the iSCSI traffic down the iSCSI portion of the card and use the ethernet portion of the card to do NFS.
Here are my vlans I am working with..
vlan 420 = fcoe vlan 500 = NFS vlan 1000 = iSCSI
I have my interface currenly set as the following on the Nexus 5000.
I found intermittent link down(20~40 seconds average) occurred about 1~10 times every month. SAP reported a lot of active connections are disconnected and I used a batch to ping and found "requested time out" about 30 seconds.And Windows, SQL server, Nexus 5010 do not show any errors. We run cluster and cluster does not fail over.And I don't know which cables or nics cause this issue. When it happened, almost all servers are unreachable. For example, SQL server 1 -> SQL server 2, IBM HS22-1 -> SQL server 1. However, some connections are not dropped sometimes. It varies each time.PS: I run this topology last year without any problems but it started intermittent link down from 2011/1/7. Because there is no errors in Nexus 5010, it is difficult to troubleshoot. Cisco TAC recommended us to implement virtual port channel yesterday. Could I use "errdisable detect cause" to detect what caused the intermittent link down? Is there any error logs or switch parameters/status can use to troubleshoot?
Basically I am trying to use Wireshark to do a packet capture on a Nexus 5010. I want to do a monitor session on on the switch so I can capture from a source port to a destination port on the same switch. I can configure the source port but when I go to configure the destination port I get "ERROR: Eth102/1/4: Configuration not allowed on fex interface". I have tried to reconfigure this port as a switchport but "switchport mode access" command does not take. I don't want to make any changes to any other ports but this one.
Here is an example of what each switch logs when a server drops offline. Sample logs taken between 5:32am and 5:35am on Feb 20. This particular one was having problems all weekend. Switch #1 encountered over 2000 interface resets. The corresponding VPC port on Switch #2 only had 13 resets.

I'm not sure if I'm missing something basic here however i though that I'd ask the question. I recieved a request from a client who is trying to seperate traffic out of a IBM P780 - one set of VIO servers/clients (Prod) is tagged with vlan x going out LAG 1 and another set of VIO server/clients (Test) is tagged with vlan y and z going out LAG 2. The problem is that the management subnet for these devices is on one subnet.
The infrastructure is the host device is trunked via LACP etherchannel to Nexus 2148TP(5010) which than connects to the distribution layer being a Catalyst 6504 VSS. I have tried many things today, however I feel that the correct solution to get this working is to use an Isolated trunk (as the host device does not have private vlan functionality) even though there is no requirement for hosts to be segregated. I have configured:
1. Private vlan mapping on the SVI; 2. Primary vlan and association, and isolated vlan on Distribution (6504 VSS) and Access Layer (5010/2148) 3. All Vlans are trunked between switches 4. Private vlan isolated trunk and host mappings on the port-channel interface to the host (P780).
I haven't had any luck. What I am seeing is as soon as I configure the Primary vlan on the Nexus 5010 (v5.2) (vlan y | private-vlan primary), this vlan (y) does not forward on any trunk on the Nexus 5010 switch, even without any other private vlan configuration. I believe this may be the cause to most of the issues I am having. Has any one else experienced this behaviour. Also, I haven't had a lot of experience with Private Vlans so I might be missing some fundamentals with this configuration.
I have a 5010 that simply won't load any system image. Loads the kickstart image just fine, but once at the Switch(boot)# prompt just give me garbage when I enter "load bootflash:n5000-uk9.5.1.3.N2.1b.bin Restarting system.

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?

I have a doubt about upgrading Memory in Redundant Supervisor Modules Nexus 7K18, i read the Cisco Nexus 7000 Series Hardware Installation and Reference Guide, and the process for upgrading the memory in redundant supervisors do not says that i can have a lose of service, but it also says that both supervisor modules must have the same amount of memory for redundancy to work;If the switch has two supervisor modules, both must have the same amount of memory. If you upgrade the standby supervisor module to 8 GB of memory, you must then switch the active supervisor to standby and upgrade the new standby supervisor to 8 GB of memory.
We have two Nexus 5010 to test the solution. As part of the testing we upgraded the boxes from 4.2.1.N1.1 to 5.0.2.N1.1 and after the reboot the switch lost all of the VLANs. We put the VLANs back and when we got to the private VLANs we got the following error:
%PRIVATE_VLAN-2-PVLAN_ASSOC_UP_FAILED: Failed to bring up the association between 530 & 531
I am experiencing an issue where NX-OS on our 5010s is allowing both Local AND TACACS authentication concurrently. If I don't configure any aaa authorization commands, the locally logged in user has unmitigated access to the device. Once I enable aaa authroization, all commands issued by the locally logged in user are denied by ACS, but they can still log in to the device. When I comb through the logs on the ACS server, I see successful logins when TACACS credentials are used, and also the failed attempts when the locally configured credentials are used. On the switch, however, I receive "%TACACS-3-TACACS_ERROR_MESSAGE: All servers failed to respond" when using locally configured credentials on the switch itself. We are running ACS v4.2.
I am having issues trying to combine two modules into one VDC. The modules are as mentioned below: When I try to combine module 1 & 10 as shown above, the nexus 7000 switch displays 'Not compatible'. I've read the online guide and it mentions that the F2 and M1 module cannot be combine into the same VDC. Problem is, my customer has already purchased the module, how do i solve this problem? If I separate the VDC, how does module 1 talk to module 10 if user wants to send traffic to Internet or Server Farm?
Is it possible to implement LLQ(QoS) on ethernet modules in the Cat 6500? For this feature, I can only find documentation about ES+ modules or SPA/SIP modules! (according to the feature navigator LLQ is supporten on the concerning HW and SW image)
I am working on a project to connect 2 switch stacks via 10 Gb fiber. I am told that the 3750Xs do not natively receive the 10 GB SFPs. What part numbers do i need to order to make this work? Is there any IOS image requirements?
While configuring PoE Ethernet EHWIC PoE modules with ISR G2 routers Cisco DCT gives a warning to select AC Power Supply with PoE ‘PWR-3900-POE’. Do we need to select the PoE power supply for Enhanced EtherSwitch SM PoE modules also (at present it does nt show any warnings)?
I have already understood the following notice for using VSS function with 6700 series modules.For example there is the compatibility HW revision issue between the 6700 line card and CFC or DFC and so on. [code]
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?
We currently have two 6509's running in VSS, both switches have a WS-6748-GE module in slot 3. I'm in the processing of removing these modules. I will then be replacing them with a different module type, but I need to know how to remove the old configuration of the previous modules.
How to configure my serial modules on my 2600 and 3640? Each router has the WIC-2T with two cables connecting them. I tried to ping one router from the other, but no luck. Serial IP address I just made up, this is my home lab, so if I messed those up some how,
Here is the running config for each rotuer:
2610: Current configuration : 1071 bytes ! version 12.3 [Code]...
I have a question. I have a 6500 with two supervosrs and they both have CATOS. One of them failed and I need to replace. As long as the hardware is the same does the CATOS have to be indentical or can this be different.
I've installed second WS-X6748-SFP linecard on my catalyst 6509 with sup720-3b and after that NAM-2 and IDSM-2 module become inaccessible from management network. I can only login with session slot N proc 1.When I execute #hw-module module 4 reset, modules become accessible.
#sh module from cat6509
