Nexus 5548UP for SAN Switch
We have purchased a Nexus 5548UP switch for our SAN environment. I've only configured it for jumbo frames and currently doing testing on the performance, as some say use jumbo frames while others say do not. My question is, and I know this is a loaded question but how do you guys go about configuring your SAN switches? What exactly are you configuring on it? Such as for performance tuning or the like. The reason I ask, is we have the switch and it's pretty much working, but I'd like to learn more about it and how to tune it and fully take advantage of the switch.
That is correct, between two Dell Optiplex workstations. We also tested between the server that will go into prod and an Optiplex, but once again the Optiplex could be the limiting factor. You think that could be it? Here's my config, so you know how it's setup right now.

Configuring Nexus 5k for SAN switching between UCS 6100s and NetApp storage
We are trying to get our UCS environment setup to do SAN boot to LUNs on our NetApp storage. We have a pair of Nexus 5Ks with the Enterprise / SAN license on them and the 6-port FC module installed. What needs to be done to configure the Nexus 5000 to operate as the SAN switch between the storage target and the UCS environment?
I'm still not seeing the LUN on the NetApp device from my service profile. Here are the outputs from the two
commands you referenced here along with a few other commands if they help at all.
Port fc2/1 is the conneciton to the UCS 6100 with FCID 0x640004 being the vHBA in my Server profile.
Port fc2/5 is the NetApp target. I have the LUN masked to the vHBA port name 20:00:00:25:b5:01:00:ff
I have just the wwpn from the vHBA in my server profile and the wwpn of the NetApp target port zoned together. I'm not seeing any FC traffic at the NetApp though from looking at the statistics. Do I need to include something else in my zoning?
Again, any assistance would be appreciated. This is obviously our first venture into FC... -
is it possible to change the airflow of the Nexus 5548UP in the field by replacing fan and power supply or must the correct airflow been ordered.
I just completed the change of airflow direction for Nexus 5548UP while the switch is still online and running. It is possible to swap fan and power modules without shutting down the switch. There are few catches that you need to pay attentions when you want to change the airflow directions:
To swap two fans and two power modules on Nexus 5548UP while it's running:
1) make sure you have the latest IOS or at least 6.0+, I have system: version 6.0(2)N2(1). Also, please don't forget to save running config just in case if the switch will be shutdown.
2) make sure you have all your new fans and power modules unpacked and ready to be installed
3) connect to the switch console port to monitor the logs and status
4) Pay attention to the switch console, it will give out warnings about fan failure (but switch will continue to run).
5) Important: The first new fan that you just replaced (with opposite airflow direction), the switch will detect the the incorrect airflow, and begin to give out warnings with countdown timer. You have only less than 60 seconds to complete the rest of swapping before the switch will shutdown. Not only you need to swap out each module quickly, but need to pay attention to each new module wait for it online before replacing the next module.
6) To start the process, insert in the first new fan with opposite airflow direction, take about few seconds and wait for spinning up [green light]. The switch console will display: "incorrect airflow detected, the switch will shutdown in 60 seconds.....". Just move onto next step...
7) replace the second fan, wait few seconds for new fan to spin up [green light].
8) replace the first power module
9) Important: make sure the first new power module is online [green light], then you can proceed and replace the second power module.
10) Completed! you may check "show inventory" to see if all new fans and power modules are online and shown. The switch was up and running the whole time.
Please give rating if it helps you! Thanks! -
I am working on a project that was handed down and several different engineers got their hands on. The project is (or should have been) a simple data storage/center. Fixing all the design problems has left me with very little time to research the security folks issues and I need help.
We are using Cisco Nexus 5548UP for our data center core and distribution/routing to encryptors connecting our remote sites which use Cisco 3750X series switches. The Nexus is running NOS 5.2(1)N1(4) and the 3750s use 12.2(55) IP base.
These are our particular issues:
1) For management and monitoring, what would be a good product to use to support this? If Cisco Prime Infrastructure, what ports would need to be allowed/opened through firewalls/ACLs (SNMP, syslog, etc)?
2) For switch login, the network security folks are reluctant to use TACACS and want to push for LDAP instead. Using Active Directory, is there any way to get the Cisco Nexus 5548UP and Cisco 3750Xs talking to Active Directory? I've found both 'yes' and 'no' answers online and am not sure. Do I need to use a different NOS and/or IOS? Are there specific directions somewhere? Or is it not possible?
3) Without TACACS, is there any way to implement command logging to a syslog server on the Nexus? On the 3750s, I make the following changes and all commands are relayed to our syslog server:
Enable
Configure terminal
Archive
Log config
Logging enable
Logging size 500
Hidekeys
Notify syslog
End
Is there anything similar for the Nexus?
4) In conjunction with #3, we need to be able to log each login attempt (success and failure) to a syslog server on the Nexus. On the 3750, using the "login on-[failure/success] log", it is can setup easy enough. On the Nexus, I haven't been able to find anything similar. I can't find any instructions on setting this up on the Nexus, though.
5) What IOS/NOS do we need to use to be able to lock out users after 3 failed logins (again, without using TACACS)?
If you need more information, please ask.
V/R,
ChrisThe LRM is s special case transceiver which supports 10 Gbps over older FDDI grade multimode fiber when used with a mode conditioning patch cord. It is not supported on the Nexus 5548UP.
The SFP-10G-LR is used with single mode fiber for spans up to 10 km in length. It is supported on the 5548UP (and most every platform of Cisco's that takes SFPs).
Please see the product data sheet here. -
Hello,
I am trying to setup LACP on the Nexus 5548UP 10 Gig switch on Port-channel 3. However, when I setup LACP, eth ports 7 and 8 (on Port-channel 3) go into either inactive or down state (as below). The 10 gig ports (7 and 8) are connected to a server which has LACP capability.
ns5500(config-if)# do sh port-channel summary
Flags: D - Down P - Up in port-channel (members)
I - Individual H - Hot-standby (LACP only)

Channel
1 Po1(SU) Eth NONE Eth1/15(P) Eth1/16(P)
3 Po3(SD) Eth LACP Eth1/7(D) Eth1/8(D)
LACP setup as follows:

switchport access vlan 10
speed 10000
interface Ethernet1/7
switchport access vlan 10
channel-group 3 mode active
interface Ethernet1/8
switchport access vlan 10
channel-group 3 mode active
It would be great if anyone can help me with getting LACP up and running on the 10 Gig Nexus 5548UP. Please let me know if you need more information.
Thanks!Thanks for your response. I do have vlan10 created and it is active. Thanks for correcting individual state instead of inactive.
I ran a few lacp commands below including "show lacp counters"
ns5500(config)# show lacp counters

By looking at LACP PDUs can we say that LACP is up and running?
ns5500(config)# show lacp port-channel

In the below command, it still says, interfaces 7 and 8 are down? What does that mean? An issue with the host? Is there anyway to test the nexus switch to check if it is doing its part and working correctly?

Hi,
Any suggestions for SAN Switch 16 Port ( All Active) from MDS series.
Thanks in advance!!DCNM-SAN-M91-K9 - very nice to have if you want to track switch utilization, manage multiple fabrics at the same time. Not a must have ..but a nice to have.
M9148PL8-8G-SFP - i believe you must purchase this to activate an extra 8 ports to give you a total of 16 ports.
M9100ENT1K9 - if you have requirements for advances features like IVR then you would need this. If you just need to create zones, VSANs ..you don't need that license.

Do we have a built-in option for web based tool in Nexus 5548UP switches for management purpose?
I have purchased Nexus 5548UP switch, i want to know if we have a built-in option for web based tool to manage and configur it just as ASA have ASDM. If there is no such options then what are the options available that can be freely available and can be used to get performance monitoring done.
Message was edited by: Praveen VarunDCNM (Data Center Network Manager) runs on a server (Windows, RHEL or Solaris) and can be used to manage Nexus devices. It's free for Nexus 1K through 5K devices (paid license required for Nexus 7K management).

There is not a "built-in" management product like ASDM for ASA. -
Connecting many Brocade switches to Nexus 5548UP
Hello,
I have a SAN network composed of few separate PODs. Each POD is divided into SAN-A and SAN-B. Most of those PODs are Brocade switches (FOS 6.1). There are also few Nexus 5520s. Now, we have built new core infrastructure with Nexus 5548UPs and many MDS 9148s. We would like to move all servers and sotrage from old Brocades to the new SAN. As we cannot move all devices at the same time, all segments must be connected to the core for some time. Each POD has different zoning. Some zonings on Brocade switches are based on PWWN, some on Domain ID and Port ID. In my opinion, the only way of successfuly connecting all PODs together is to merge zones manualy (in excel, etc). and paste them on all switches. However, maybe there is some other way of merging all zones? What if I leave Nexus 5548UP in native mode (so zones from Brocade will not get merged), and only implement that manually merged zoneset on Nexus 5548UP? Will the ISL links get isolated due to zoning merge failure? Or they will maintain operational state even if zones are different on each POD? I do not have any lab boxes, so I cannot test it. Any advidse will be appreciated.
Best regards,
Krzyszofwell since you can not cluster the 45K as a virtual switch ( Cisco with new sup will start support VSS in the 4500 try to check which sup exactly and if you can upgrade as this will make a significant improvement to your design )
anyway the only method that you can use currently is the traditional way which is depending on STP ( use rapid-PVST)
from each N5K use one separate link to each 45K and STP will put on of the links in blocking mode
however you might do some STP and vlan design for load sharing where you can send vlan x over link1 and vlan y over link b to the 45K using STP cost

I need a recommendation for SAN (Actually NAS) ethernet switches.
Hi, we have one Dell blade chassis with 8 servers ---- connected to stacked switches (3750) with EtherChannels ---- to NetApp (Controller 1 and 2 accordingly). Unfortunately, Dell blade servers only supports 1Gbps for port and NetApp also supports 1Gbps for each port (ports are all ethernet, not FC)
Questions
1) What kind of switch do you recommend? I know that it is not popular to use ethernet in SAN I just recognized that we have NAS, what do you recommend switches for NAS?
not SAN, so any MDS 9000 series don't work because it supports limited ethernet ports (many FC ports). I need many ethernet ports at least 48 ports from each switch. I know Nexus is one of candidates, but want to double check.
2) Most of vendors ask what kind of connection I have. I said usually just ethernet, not FC, not FCoE. Is it right? I believe that since I found NAS, it is "Ethernet"
3) The reason that I am looking for different switches is there are huge packet dropped (outbound) in switches (outgoing toward both dell servers and netapp; incoming is ok) We recently moved PtoV so, it is possible that traffic volume was increased. But output doesn't give me lot of information like below. Do you have any recommendation for further t-shoot?

LMS User Tracking for NEXUS 5548UP
Dear,
A while ago I received a ticket from one of our customers because User Tracking was not working for NEXUS 5548UP on LMS 3.2. I opened a TAC case for this but this was normal since it is a Datacenter switch. Now the customer came back on this because they really want to see which server is connected to which switch port. I understood from the TAC engineer this is not on the roadmap to integrate in LMS 4.x. They want to know if there exists another product (they thought about DCNM) and wanted to know how this integrates or works together with LMS...
Kind regards,
Sven LaureyssensMy latest understanding of User Tracking and Nexus 5K series is that it is not supported due to a limitation of the MIB support in the NX-OS.
The current DCNM (release 5.2) is distinct from the LMS and Cisco Prime umbrella but that wil be changing a bit moving forwad as DCNM is enhanced and rolled into the Cisco Prime family. Last I heard there should be some information coming out of Cisco Live this week and a new release will have some additional functionality and better integration. Still, I doubt we'll see UT for the 5K due to the NX-OS limitation.
One way to do what you're asking apart from use of any of the Cisco products is to enable LLDP on your Nexus and servers. That will at least give you the ability to pull the information from the NX-OS command line ("show lldp neighbor") -
Nexus 5548UP with 1Gb ether to 10Gb ether on same switch
I have a Nexus 5548UP switch with a couple of systems some of which have been configured with 1Gb nic's running various OS's and other that have 10Gb nic's. When I try to SSH from 1Gb box to a 1Gb box everything is fine, when I SSH from 1Gb to 10Gb box it does not work but 10Gb to 10Gb boxes will work. The switch is a fresh install and has one VLAN 51 the first 2 ports are setup with LACP and the only differences is speed of 1000 and 10000 for the boxes attached. Is there some trick or additional configuration that is needed to make 1Gb to 10Gb work for SSH and other applications? I trying to setup some test boxes now to have a repeatable environment and will update when completed.

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 get a successful response from Server A when I ping the N5K-C5548UP Switch (VLAN 40 interface (10.144.40.3) .But if I try to ping from Server A to Server B or vice-versa the ping fails. From N5K-C5548UP I can ping successful either Server A or Server B. What am I doing wrong here? Is there any additional configuration that I need to add on the Nexus Switch? Please Help. Thank you.no, no secret aukhadiev
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:

Cisco Nexus 5548UP to Brocade SAN Connectivity
Hi,
I have a Server-SAN-Storage setup as shown in the attachment/below. There are new Cisco UCS rack mount servers with VIC 1225 and Virtual servers on VMware Esxi hypevisor connected to a new Cisco Nexus 5548UP switch in IP+FCoE mode. The new 5548 switch then connects to an existing production SAN of Brocade 48000 Director SAN switch which connects to storage in production environment.
I need to know the best way to connect the 5548 switch to the Brocade SAN switch without disrupting the existing Production SAN environment i.e. Brocade SAN switch configurations & setup e.g. Fabric Principal switch. priority etc.
Would configuring the 5548 switch in NPV mode be best practice?See Figure 6-2 Converged Multi-hop FCoE Network Design Using FCoE NPV
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/operations/fcoe/513_n1_1/ops_fcoe/ops_fcoe_npv.html
You have to use NPV on N5k, there is no FC interop support on N5k, to connect to Brocade. -

Cisco Nexus 5548UP Switch Current Version 5.2(1)N1(4)
Thanks.I had the same question, so I opened a TAC case to find the right software version. I was told that the software listed as available on the bug report were custom NX-OS builds and that there are no patched versions available for the 5548p. The support engineer also said that the Nexus 5k upgrades were not expected until November or December. The best advice I could get was to subscribe to the bug report and wait to be notified of an available upgrade.
