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.

Cisco Switching/Routing :: Nexus 5010 With 1G And 10G Uplinks In VPC?

Aug 12, 2012

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?

Cisco Switching/Routing :: Nexus 5010 Interconnected With Two UpLinks

Dec 11, 2011

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.

Cisco Switching/Routing :: Any Function Built In Nexus 5010 To Detect Intermittent Link Down

Nov 23, 2011

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?

Cisco Switching/Routing :: Nexus 5010 - Capture From Source To Destination Port On Same Switch

May 19, 2013

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.

Cisco Switching/Routing :: Private Vlan / Etherchannel And Isolated Trunk On Nexus 5010

Feb 9, 2011

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.

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 :: Upgrading Memory For Redundant Supervisor Modules Nexus 7K18?

Mar 6, 2012

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.

Cisco AAA/Identity/Nac :: Nexus 5010 Allows TACACS And Local Authentication Concurrently

Jun 6, 2011

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.

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?
