Sep 29, 2012
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'm having difficult getting this switch to boot from flash. I do not understand why it is trying to load "b1" from "bs1" instead of something from flash. [code]

i recently bought a new Supervisor Engine 720 WS-SUP720-3B and 48-port 10/100/1000 RJ45 EtherModule WS-X6148A-GE-45AF. Once i fired it all up i got this error %C6KPWR-SP-4-UNSUPPORTED: unsupported module in slot 2, power not allowed: Unknown Card Type. the System image file is "bootdisk:s72033-ipservicesk9_wan-mz.122-18.SXE6a.bin".
I have a 6509 up and running the same mods and working fine BUT the System image file is sup-bootdisk:s72033-ipservicesk9-mz.122-18.SXF7.bin. Is the boot image what is causing my isses?

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?

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.

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'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]

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 cisco 6503 - e series switch which runs c6sup22-psv-mz.121-26.E4.bin. Both superviser engine and MSFC2 card run the same IOS image i guess. In my boot flash their is another image c6msfc2-jsv-mz.121-4.E1. o what is the difference between these images c6msfc2-jsv-mz.121-4.E1 and c6msfc-boot-mz.121-4.E1.

after upgrading IOS image to V15 on four 2960S switches: Should I make the boot loader image to match the IOS version?I never thought about this while upgrading IOS image unless there is boot issue. I googled for answer but no luck there...
I checked download section on Cisco.com for C2960S-48FPS-L switch and there is simply no boot loader image..The running boot loader is C2960S-HBOOT-M Version 12.2(55r)SEThe running IOS is: 15.0 (2) SE2.

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've 3750X switch that isn't loading email. then I went to rommon mode and accidently for "format flash". after that I loaded 15.0 SE2 s/w on it using tftp server but it doesn't boot up with that image. flash had only .bin file after I loaded it from tftp server.
since it wasn't booting up, I did format flash again and thought to load image again from tftp server but now, it doesn't load image from tftp server.
