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.

Nexus 5548UP with Checkpoint firewall
I know this is a little out of scope, but was hoping someone would have some insight.
I have two Checkpoint firewalls connected to Cisco Nexus 5548UPs 10G. I am noticing a lot of dropped RC on the Checkpoint interfaces. I'm wondering if the firewalls cannot support the fast cut-through speed of the Cisco switches. Is there anything I can do on the Cisco side to help the Checkpoints handle the traffic? Flow control maybe? Thanks.Hi Adnan,
Kindly check the PPT attached for more detailed design tips for same.
Best Regards

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:

on first switch i made slot 2 as fc ports & after reload i can see fc ports.
slot 2
port 1-16 type fc
However with same procedure on switch 2 , i cant see any FC ports nor module 2 ports.
if i turn module 2 ports to ethernet i can see E2/1 - E2/16 , but no ports when they are configures as FC.
any idea ???
Confused as both switches have same lic installed.
Thanks in Advance.After the port type has been changed from Ethernet to FC, the FC port will not be enabled on the switch until FCOE feature is enabled:
N5K(config)#feature FCOE
C license checked out successfully
fc_plugin extracted successfully
FC plugin loaded successfully
FCoE manager enabled successfully
FC enabled on all modules successfully
Enabled FCoE QoS policies successfully
After that, we verify that the port type is changed successfully and the FC ports appear on the switch:

Nexus 5548UP/2232PP/FCoE
Hi,
In my enviroment I have a datacenter with 2 Nexus 5548UP with FCoE Licence. As I am new to storage networking I need some information about the configuration of FCoE.
The enviroment is :
2 x 5548UP Switch
2 x 2232PP FEX
1 x Host with Emulex OneConnect OCe10102-F interface
1 x storage with FCoE interface.
How many virtual SANs we can create with a single stoarge device.
I have to configure this 2 5548UP Vs the 2 FEX 2232PP with FCoE.
1) I have to map each vsan with a Layer 2 FCoE Vlan?
2) How I can distribute the VSans (and the FcoE Vlans) and the Ethernet Vlans from the 2 FEX 2232PP Vs the 2 5548UP? How many Links? Is better to do a Port-Channel or different Port-Channels? Best Practices?
3) In which way we need to configure the Teaming? Active Standby or Active Active?
4) I studied that, it is possibile to do an ISL Trunk between the two Nexus 5548UP switches...right? Can I Create a port-channel and allow all the vsans?
Kindly guide me with proper connection diagram and configuration steps.
Thanks in advance!
GauravAssuming FEXes are already connected and operational. Nexus 5548 cannot run in NPV mode. You have to configure zoning in addition to following configuration.

Hi
I need a switch that supports FC, FCoE and iSCSI traffic. The switch that has been suggested to us is Cisco Nexus 5548UP.
I have the following queries regarding this switch:
1) At our end, I have AMS 2100 Hitachi Storage which has iSCSI & FC Ports. I also have Qlogic CNA card at the server end which supports both ISCSI & FCOE. For FCoE protocol based traffic, the storage to switch connection will have to be FC and the switch to server connection will be FCoE. Can you please confirm whether, if this will be possible through the proposed Cisco Nexus 5548UP switch?
2) The specification for the Nexus 5548UP switch claims that it supports 10 Gigabit Ethernet. Can you please confirm if this relates to iSCSI support that the switch provides?
3) We are going to use -SFP-FC4G-SW & SFP-10G-SR SFP for fiber connectivity. Can you please let us know the what these SFP are used for and whether they assist in FC and FCoE traffic forwarding?
4) We are also going to use Nexus 5500 Storage License, 8 Ports. Does this indicate that only 8 ports of the switch can be connected to the storage? Among these ports, can we configure 4 ports for FC and 4 ports for iSCSI (keeping in mind that our storage has both FC and iSCSI ports)?
5) Is there any License required for enable FC, FCoE and iSCSI protocols?
An early resolution of these queries will enable us to make a decision regarding the switch.
Thanks

The "UP" in the Nexus 5548 stands for Universal Port. This means that each port can support FC, FCoE and Ethernet. So, a 5548 has 32 ports of SFP/SFP+. Each port can support and push 10 Gbps at a 1:1 oversubscription rate.
There is an optional 16-port SFP/SFP+ module, N55-M16UP, which will add an additional 16 Universal Ports.
Because they are "universal" they can support 1/10 Gbps FCoE and Ethernet as well as 1, 2, 4 and 8 Gbps FC. -

Actually the topology looks simple and easy but there must be some missconfiguration on my side because i can't see any of IDs (P81E's wwpn and mac address info) from the Nexus 5548UP.
I connected my 5548UP to MDS 9124 for providing the FCoE traffic to the C-200 Farm.
Then i configured the MDS with NPIV and converted couple of ethernet ports to the FC ports on 5548UP (which i'm using to connect to the MDS)
Finally i connected my C-200M2's VIC to the 5548UP but i couldn't see any information about server. The ports actually are up. But can't see nothing.
Some help and advises will be appreciated.Padma,
Right now i connected the N5548 directly to the storage for that reason you can not see the fc uplink connections on running-configuration.
On Nexus 5548 ;
Ethernet 1/1 and Ethernet 1/2 are the server ports (P81E)
Ethernet 1/15 is the Uplink Ethernet port
Fc 1/31 1/32 is the Storage Ports
Storage has been configured for the wwpns and LUNs.
And here is the configuration :

Cisco Nexus 5548UP and FI6248UP compatibility with FC SFP
Cisco Nexus 5548UP and FI 6248UP comes with Unified Ports. What are the SFP types this port can take? 1Gig, 10Gig and 2/4/8FC. Could you please clarify?
Thanks,
CheriyanHi Cheriyan,
Here is te URL to the 6200 series FI data sheet:
http://www.cisco.com/en/US/prod/collateral/ps10265/ps11544/data_sheet_c78-675245.pdf
Check for the table to supported SFPs.
Same for the 5500 switches

Nexus 5548up OS 5.1(3)N2(1) with L3 Card
I find some inconsistent behavior in the above platform. After a clean reboot, the interfaces are up, but cdp neighbors are not showing. The switch has no configuration (after reboot with no startup-config). To make things worse sometimes it will boot properly and show cdp neighbots, other times it won't. When that happens all the port-channel and other configurations don't work as well. The switch has L3 card. Any ideas?
I have tried installing NX-OS 5.2 and then moving back to 5.1. I want to stay at 5.1 That didn't solve anything.

Nexus 5548UP lacp with IBM AIX P740
We are currently working in a lab to configure our first pair of 5548UP(with a 2232PP on each) with FCoE to an IBM p740 AIX server. On the Nexus side I have confugured the physical port e100/1/1 (2232pp) to be in a channel-group that will be part of a vpc with the other 5548UP switch, I am trunking all vlans in the etherchannel with the IBM server. Everything is working, i have the port-channel UP, the vfc and vpc when I use ''channel-group x mode ON'' on the physical ports and on the server side the 803.2ad is not active, it's configured ''roundRobin''.
Suppose I want to use LACP for the connections with the server should I configure the Nexus switch port with ''channel-group x mode active'' or ''channel-group x mode passive''? When the server is configured with ''802.3ad'' enabled and when I have ''channel-group x mode active'' or ''passive'' it doesn't work, the port-channel x does not come UP.
Does anyone have an explenation of how I should be configure?
ThanksHello,
Using LACP passive or active mode should not make much of a difference as long as one of the sides of the port-channel actively negotiates LACP. In most cases, we just configure both sides to be LACP active.
When you say the port-channel is not working when using LACP, what are the symptoms?
Are the physical ports in "I" state?'
'show port-channel summary' will show this
What does the output of "show lacp counters interface port-channel X" show?
This command will tell you if the Nexus 5K/2K is receiving LACPDUs from the IBM device (and if we are sending them). I would suggest to collect the LACP counters to verify that we are receiving the LACP packets from IBM, otherwise Nexus will not bring up the port-channel. Here is an example output from my lab switch:

Partial collection Failure for nexus 5548UP in PI 2.1
Hi there,
I get "Partial Collection Failure" in the inventory collection status in Prime Infrastructure for all my Nexus 5548UP (8 devices).
i have seen in the PI 2.1 release notes that a bug CSCum16230 which look like my problem has been resolved in PI 2.1 but i continue getting the "partail collection failure"
Would like to know if the bug is still exist or get any other help to solve this problem.
Regards,
Alon.hello
I have this problem as well...
we've got four N5K-C5548UP. Two with a layer 3 daughter card and two without.
interestingly we see the issue just on those boxes with the l3 daughter cards N55-D160L3-V2 installed...
Any help or ideas are highly appreciated
regards
roman

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 L3 card swap out for L2 cards
Hi everyone,
I have two Nexus 5548UPs and I am going to swap out the L3 cards and put in L2 cards.
I can't seem to get a straight answer out of TAC so I thought I'd try here.
How will this affect the current configuration (apart of course from removing the L3 capability)?
Will swapping the cards clear the config?
Will swapping the cards clear the licenses?
It's a very simple config so that doesn't worry me that much .. but if it will clear the licenses installed than I need to take action on that.
Thanks,
BRno, 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:

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!
