Cisco Switching/Routing :: Nexus 5010 And Qlogic 8240 CNA To Work With Esxi
Dec 6, 2011
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.
interface Ethernet1/17

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.

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 the following devices :
-1 VM Host
-2 Layer 3 switches
I would like to provide full redundancy for all vlans being used by VM Guests on the VM Host as well as the management vlan being used by the VM Host.I have created two LACP etherchannel connections on the VM Host. Each etherchannel from the host consists of 4 ports spanning a single NIC. One etherchannel connection goes to a trunked etherchannel connection on switch 1, and the other etherchannel connection goes to a trunked etherchannel connection on switch 2.Switch 1 and switch 2 have an etherchannel connection between them that carries all of the vlans in the topology.Vlan 2 is the managment vlan. Vlans 3, 4, and 5 are vlans that VM guest systems will be using for normal data traffic.
I intend to use switch 1 as the VRRP active router and spanning-tree root bridge for vlans 2 and 3.I intend to use switch 2 as the VRRP active router and spanning-tree root bridge for vlans 4 and 5.The spanning-tree configuration is using multiple spanning-tree with two instances. Instance 1 has vlans 2 and 3 associated and Instance 2 has vlans 4 and 5 associated. I would like to have this topology be fault tolerant to the point where if one of the etherchannel links between the host and one of the switches goes down, (for example, if switch 1 was powered off) traffic will be automatically redirected through the other functional link. I believe that my VRRP configuration would allow for a fairly quick failover of layer 3 services, but I am not certain that my design will be functional at a layer 2 level.
What I am uncertain about is how spanning-tree will converge. I am assuming that the virtual switch on the VM host will not be forwarding any BPDUs being sent by either switch. Would either of the links connecting to the host be considered a redundant link by either switch?Would the link between switch 2 and the host be inactive for all vlans in MST instance 1 during normal operation?Conversely, would the link between switch 1 and the host be inactive for all vlans in MST instance 2 during normal operation? Would all links remain active for ALL vlans? Would this mean that some traffic may travel through switch 2 to reach switch 1 instead of going directly to switch 1?

I have a single Nexus 7K (6.x) with only F2 modules and I would like to SPAN the same source interfaces and vlans to mulitple destination servers (interfaces). When configuring SPAN to a single destination traffic gets replicated successfully but when I add an additional destination to the same SPAN session then none of the destination interfaces receive any traffic. As soon as modify the SPAN to include only a single destination interface it works again. I'm guess this is a limitation of the Nexus 7K 6.x code or the F2 modules.

I've been testing some QoS policies, and I have not been able to make a type QoS policy work in the outbound direction. Simple example:
ip access-list QOS-VOICE
10 permit ip any 10.120.11.0/24
20 permit ip 10.120.11.0/24 any
class-map type qos match-any IN-VOICE
description Voice/VoIP/IPT
[code]....
The 7Ks are running NX-OS 5.2(4). Just wondering - has any one got an outbound qos policy to work on a N7K?

we've been using IOS for a long time, but are relatively new to NX-OS. We've got a central syslog server that all our devices log to. No matter what we do, we can't get our Nexus switches to log there. Here's my current attempt:
Nexus 7009, NX-OS 6.0(1)
# sh logging server
Logging server: enabled
{redacted}
server severity: debugging
server facility: local7
server VRF: default
[code].....
The default VRF is working. I see log entries in the logfile, but nothing arrives at the syslog server. It's not a config issue on the server, because tcpdump shows that no packets arrive from the IP for loopback 0.

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.

if I can use the encrypted port as unencrypted ethernet ports? url.. Each individual port on the Cisco Nexus 5010 switch is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right.There are 20 to 28 ports on the Cisco Nexus 5010 switch, depending on which GEM is installed.
The 20 fixed ports form group 1 and are named 1/port_number. Ports 1 through 16 are unencrypted Ethernet ports. Of these, ports 1 through 8 are 10-Gigabit Ethernet and 1-Gigabit Ethernet-capable ports. Ports 17 through 20 are encryption-capable Ethernet ports.

Does the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?

We have our Nexus as our default gateway (101.1) and the default VLAN1 is setup with two subnets 101.X and 102.X. The DHCP server is using a superscope setup to accomodate the overflow of devices requesting IPs on 101, so when 101 is consumed persons are able to obtain a 102.X IP address. The setup is basic on superscope. The issue is some times the routing to the firewall with a 102.X is not always 100%. Somedays all goes well and the 102 subnet is routed out to the firewall and its a good day. However, such as today a 102.X address is not routing as it did 24 hours ago. I am perplexed as to why this is behaving unpredicatable. Here is running-config for VLAN1 to show the 102 as secondary address to VLAN1.
