Connect Nexus 5600 and Qlogic
Hi,
Have a new DC solution with Nexus 56128 switches running LAN + Native FC.
Storage Arrays shall be connected to the Nexus switches via 8G FC
Customer has Dell blade with Qlogic SAN switches, where existing zoning is done. Today these are connected to the Storage Array.
Is it possible to connect the Qlogic switches to Nexus and disconnect the Storage from Qlogic?
Dell blade server -> Qlogic FC switch -> Nexus FC switch -> EMC VNX Storage
Thinking about interoperability issues between Nexus and Qlogic.
/Jorgen
Hi,
No problem with that, just bear in mind that you have to configure NPV mode (or the equivalent qlogic name...) on the qlogic switch.
Rgds,
Felipon

I am having a problem with getting the Qlogic 8150 working in a windows 2008 R2 server. I have the SAN connectivity working but I am having problem with the networking.
I have setup VLAN 666 as the data vlan
On the ethernet trunk I have setup
ethernet 1/17
switchport mode trunk
switchport trunk allowed vlan 666 spanning-tree port type edge trunk
This does not work but if I allow VLAN 1 on the trunk it works and I have full IP connectivity.
switchport trunk allowed vlan 666,1 Any ideas why adding VLAN 1 on the trunk makes everything workThanksYou set vlan 666 as the VlanID under the Qlogic adapter advanced properties, right? Should be the last value in the scroll box.

Interoperability issues between Nexus 5k and HP storageworks (8/20q)
Hello community,
I am trying to get a VM host and a windows server to connect to their storage across a nexus and HP (Qlogic) fabric switch. This is currently having issues with the VM host unable to see the datastores, possibly due to interoperability between Cisco and HP (Qlogic)
I have configured and tested the connectivity using only the cisco nexus and this worked, I then tested it using only the HP fabric switch (HP 8/20q) and this also worked.
However, when using the HP and Cisco Nexus as shown in the attached diagram, things stop working.
The connection is using Native Fibre channel, On the Cisco side I performed the following steps
Configured the Nexus with Domain ID 10 and the HP with Domain ID 20.
Connected the 2 fabric switches on fc1/48 (Cisco) and port 0 (HP) and confirmed that the ISL came up (E_port 8G), I confirmed connectivity using fcping both ways.
I connected the SAN to the Nexus and the servers to the HP
Configured VSAN 10
Added interfaces fc1/41 to 48 in VSAN 10
Created 2 zones ( ESXI and Windows)
Added the PWWN for the ESXI server and the MSA2040 to the ESXI zone
Added the PWWN for the Windows 2k8 server and MS2040 to the Windows zones
Created zoneset (Fabric-A) and added both the above zones in it
Activated the FABRIC-A zoneset
The result is that the zones and zoneset are synchronised to the HP switch .I confirmed that I was able to see the servers and SAN WWN in the correct zones on the HP.
From the 8/20q switch I am able to fcping the SAN, Nexus and servers, however the Nexus is only able to fcping the SAN and the HP, it returns a “no response from destination” when pinging the servers.
I have added the FCID for all the units in the same zones to see if it makes any difference to no avail the result seem to be the same. I have gone through various Nexus/MDS/HP/Qlogic user guides and forums; unfortunately I have not come across any that shows this specific topology.
source for HP user guide is here: http://h20565.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02256394
I’m attaching the nexus config and partial view of the “show interface brief” showing the fibre channel port status

Any help and advice would be greatly appreciated. thanks in advanceHi all, after much reading, Walter Dey provided the hint to put me on the right track.
By default the Nexus 5k is in interop mode 1. However, one of the requirement for this to be "interoperable" with other vendor the FCDomain ID in the entire fabric needs to be between 97 and 127 as stated in the Cisco website.
http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/interoperability/guide/ICG_test.html
Another issue that had me and my colleague scratching our heads, was that we were seeing high level of CRC errors on the ISL interfaces. This was caused by ARBFF settings mismatch between the Nexus and the HP. This was resolved by ensuring that the ARBFF setting on the HP was set to false and the command "switchport fill-pattern ARBFF speed 8000" is configured on the ISL interface linking the 2 switches. (note that Cisco's default setting for the ports is IDLE, until this is changed the link will not stabilise)
Thanks for all your help guys. -
LACP passive mode on EvPC on Nexus 5600
I have a Nexus 5600 in a co-lo facility. The server administrators want to be able to PXE boot servers connected to an active active FEX and once provisioned bundle the two ports with LACP. On a typical switch you would put the ports in passive mode where they would act like normal ports until the server started talking active LACP after it was built. However on the Nexus while the ports show up and connected, they don't seem to operate until the port-channel comes up. While in a channel group they won't pull a MAC address off the host. If I take them out of the channel group they both pick up MAC addresses and they can PXE boot.
Anyone else run into this issue and is there something extra I need to do on the Nexus to make it work?Hi Scott,
Could you please share the network diagram along with the configuration, so that I can help you further.
Best Regards

NEXUS 56128 and FEX with beakout cable
Hello,
using two NEXUS 56128 , I wish to create enhanced VPC architecture with FEX 2248TP.
My question is : can I use 40Gbs ports on NX56128 with QSFP breakout DAC cable (40G to 4x10G) to connect FEX 2248 ?
regardsHi Yallies,
For the Nexus 56128 (http://cs.co/9002c2aC) , it supports 8 true 40 GE QSFP ports and up to 96 10GE ports ( of which 48 are UP). Since the Nexus 5600 supports high density fabric extender aggregation platform, they can be used with the Nexus 2248PQ, 2248TP. Feel free to message me directly for further assistance. Hope this helps! :)
Thanks,

ESXi 4.1 NIC Teaming's Load-Balancing Algorithm,Nexus 7000 and UCS
Hi, Cisco Gurus:
Please help me in answering the following questions (UCSM 1.4(xx), 2 UCS 6140XP, 2 Nexus 7000, M81KR in B200-M2, No Nexus 1000V, using VMware Distributed Switch:
Q1. For me to configure vPC on a pair of Nexus 7000, do I have to connect Ethernet Uplink from each Cisco Fabric Interconnect to the 2 Nexus 7000 in a bow-tie fashion? If I connect, say 2 10G ports from Fabric Interconnect 1 to 1 Nexus 7000 and similar connection from FInterconnect 2 to the other Nexus 7000, in this case can I still configure vPC or is it a validated design? If it is, what is the pro and con versus having 2 connections from each FInterconnect to 2 separate Nexus 7000?
Q2. If vPC is to be configured in Nexus 7000, is it COMPULSORY to configure Port Channel for the 2 Fabric Interconnects using UCSM? I believe it is not. But what is the pro and con of HAVING NO Port Channel within UCS versus HAVING Port Channel when vPC is concerned?
Q3. if vPC is to be configured in Nexus 7000, I understand there is a limitation on confining to ONLY 1 vSphere NIC Teaming's Load-Balancing Algorithm i.e. Route Based on IP Hash. Is it correct?
Again, what is the pro and con here with regard to application behaviours when Layer 2 or 3 is concerned? Or what is the BEST PRACTICES?
I would really appreciate if someone can help me clear these lingering doubts of mine.
God Bless.
SiMSim,
Here are my thoughts without a 1000v in place,
Q1. For me to configure vPC on a pair of Nexus 7000, do I have to connect Ethernet Uplink from each Cisco Fabric Interconnect to the 2 Nexus 7000 in a bow-tie fashion? If I connect, say 2 10G ports from Fabric Interconnect 1 to 1 Nexus 7000 and similar connection from FInterconnect 2 to the other Nexus 7000, in this case can I still configure vPC or is it a validated design? If it is, what is the pro and con versus having 2 connections from each FInterconnect to 2 separate Nexus 7000? //Yes, for vPC to UCS the best practice is to bowtie uplink to (2) 7K or 5Ks.
Q2. If vPC is to be configured in Nexus 7000, is it COMPULSORY to configure Port Channel for the 2 Fabric Interconnects using UCSM? I believe it is not. But what is the pro and con of HAVING NO Port Channel within UCS versus HAVING Port Channel when vPC is concerned? //The port channel will be configured on both the UCSM and the 7K. The pro of a port channel would be both bandwidth and redundancy. vPC would be prefered.
Q3. if vPC is to be configured in Nexus 7000, I understand there is a limitation on confining to ONLY 1 vSphere NIC Teaming's Load-Balancing Algorithm i.e. Route Based on IP Hash. Is it correct? //Without the 1000v, I always tend to leave to dvSwitch load balence behavior at the default of "route by portID".
Again, what is the pro and con here with regard to application behaviours when Layer 2 or 3 is concerned? Or what is the BEST PRACTICES? UCS can perform L2 but Northbound should be performing L3.

SAN Port-Channel between Nexus 5000 and Brocade 5100
I have a Nexus 5000 running in NPV mode connected to a Brocade 5100 FC switch using two FC ports on a native FC module in the Nexus 5000. I would like to configure these two physical links as one logical link using a SAN Port-Channel/ISL-Trunk. An ISL trunking license is already installed on the Brocade 5100. The Nexus 5000 is running NX-OS 4.2(1), the Brocade 5100 Fabric OS 6.20. Does anybody know if this is a supported configuration? If so, how can this be configured on the Nexus 5000 and the Brocade 5100? Thank you in advance for any comments.
Best regards,
FlorianI tried that and I could see the status light on the ports come on but it still showed not connected.
I configured another switch (a 3560) with the same config and the same layout with the fiber and I got the connection up on it. I just cant seem to get it on the 4506, would it be something with the supervisor? Could it be wanting to use the 10gb port instead of the 1gb ports? -
Connecting Nexus 5K to HP 3800 stack on vPC
As the title says, I am connecting a stack of 3800 switches to a Nexus 5K pair using a virtual Port Channel. However, the second connection never comes up, and in the one case we've had where connection 1 goes down, the second connection didn't take over. Is anyone out there doing this successfully?
Thanks,
Russell

Hi
I want to apply QoS scheduling using 8 classes per interface in the nexus 5672
As far as I know , Nexus 5600 have 8 queues per port
So in the ingress port, I want to apply COS mark using 8 class-maps and policy-map type qos
but I don't understand why I must apply "set qos-group" in the policy-map
and then in the egress port, to schedule the bandwidth for each class-map
I applied class-map and policy-map type queueing
but in the class-map, there is only "match qos-group", qos-group has only1~5 value
so how to apply bandwidth percent for 8 each class-map in the policy-map per port?
is it impossible?
please let me know that reason and how to do that
Thank youDuplicate posts.

Trunking nexus 5596 and netapp or exsi issue
hi
i have 2 issues with trunking between nexus 5596 and a esxi server .....can not get the servers to ping out
and the netapp connected to the same 5596 cannot ping.
if the server is a access port it works fine.
is there any tricks that are required to be configured on the nexus to make this work.Make sure we are actually tagging for those vlans on the host (Netapp/ESXi). If we are not, then this would explain why it works in access mode on the switch.

Connect Nexus 5548UP-L3 to Catalyst 3750G-24T-E Layer 3 Switch
Please help!
Could anyone out there please assist me with basic configuration between Nexus Switch and Catalyst Switch, so that devices connected on the catalyst switch can talk to devices connected on nexus switch and vice-versa? In my current setup all servers on VLAN 40 are connected on the Catalyst Switch A as shown in the diagram below, and all desktops and all other peripherals are connected on the Catalyst Switch B. I am required to implement/add a new Nexus Switch 5548 that in the future will replace the Switch A. From now I just need to connect both switches together and start moving the server from Switch A to the Nexus Switch.
The current network setup is shown as per diagram below:
SWITCH A – this is a layer 3 switch. All servers are connected to this switch on the VLAN 40.
SWITCH B – all desktops, VoIP telephones, and printers are connected on tis switch. This switch is also a layer 3 switch.
I have connected together the Nexus 5548UP and SWITCH A (3750G) using the GLC-T= 1000BASE-T SFP transceiver module for Category 5 copper wire. The new network is shown as per diagram below:
Below is the configuration I have created in both Switches:

I made a mistake without realising and the interface e1/3 was showing "Interface Ethernet1/3 is down (Inactive)". After spending sometime trying to figure out what was wrong with that interface or switch, it turned out to be that i forgot to add the vlan 40. Now the config looks like this:

Hi, is it recommended to use a native vlan other than 1 on the trunks connecting Nexus box's. It used to be that you should not use native vlan 1 on the trunks between switches. Is this not an issue anymore.
ThanksHi Chuck,
It is recomended to use a different vlan other than vlan 1 as your default vlan.
This is one of the best practices for secure the overall network.
For eg.
In a switch spoofing attack, an attacking host imitates a trunking switch by speaking the tagging and trunking protocols (e.g. Multiple VLAN Registration Protocol, IEEE 802.1Q, VLAN Trunking Protocol) used in maintaining a VLAN. Traffic for multiple VLANs is then accessible to the attacking host.

Nexus 5548 and Define static route to forward traffic to Catalyst 4500
Dear Experts,
Need your technical assistance for the Static routing in between Nexus 5548 and Catalyst 4500.
Further I connected both Nexus 5548 with Catalyst 4500 as individual trunk ports because there is HSRP on Catalyst 4500. So I just took 1 port from each nexus 5548, make it trunk with the Core Switch (Also make trunk from each Switch each port). Change the speed on Nexus to 1000 because other side on Catalyst 4500 line card is 1G RJ45.
*Here is the Config on Nexus 5548 to make port a Trunk:*
N5548-A/ N5548-B
Interface Ethernet1/3
Switchport mode trunk
Speed 1000
Added the static route on both nexus for Core HSRP IP: *ip route 0.0.0.0/0 10.10.150.39 (Virtual HSRP IP )*
But I could not able to ping from N5548 Console to core Switch IP of HSRP? Is there any further configuration to enable routing or ping?
Pleas suggestHello,
Please see attached config for both Nexus 5548. I dont have Catalyst 4500 but below is simple config what I applied:
Both Catalyst 4500
