You are probably running into bug-id CSCtz00790. (see below)
I had the same issue with UDLD no echo reply over SFP+ cables. The bug is Fixed-In 5.1(3)N2(1a)

Please tell me how to connect with FCoE UCS-mini and Nexus N5k (N5K-C5548UP-B-S32)
I have UCS 5108 Blade Server Chassis (with two B200 M3 Blade Servers inside and two FI 6324) connected to Nexus N5k switch through 4x10GE links.
I want to configure the two aggregated channels FCoE (vFC) from chassi to switch.
All instructions I've been seen refer to the fact that UCS-mini must be in the FC end-host mode, but UCSM 3.0 version does not support this mode, what shoud I do?
I set up following the instructions www.cisco.com/c/en/us/support/docs/switches/nexus-5000-series-switches/116248-configure-fcoe-00.html
But, after setup I have a fault on fabric: FCoE or FC uplink is down on Vsan 500;
And in Nexus: Vsan 500 is down (waiting for flogi)
When I do "show interface vfc 1" from Nexus CLI I see no 'Trunk vsans (up)', but
'Trunk vsans (initializing) (500)'
Unfortunately, I can't find technical notes for UCS mini (with UCSM v. 3.0), so may be You can promt any guides or suggestion for this?
Thank You in advance!The release notes of 3.0.1e, which is for UCS-mini,

CLI session limit 32 reached. Exiting. on nexus n5k
Hi Guys ,
I'm having a problem with Nexus n5k , when i'm trying to telnet to the machine ,i get this error :
"CLI session limit 32 reached. Exiting."
I can connect to it by console ,but i don;t know how to clear all those sessions .
Needs help
Thanks ,
RonI am also having this issue on out 5Ks. We resolved the problem before by consoling into the system and doing "show users" and then "clear line (vty-line)". This will allow you to ssh or telnet into the system again. But I am wondering how I can determine why this is happening all of a sudden. I have been working with our Nexus 5K for over a year and a half and have never had this issue. Now all of a sudden it has happend two time in the last 3 months. What do I need to look into to resolve this? I am not not exiting properly and it is not killing the session? Please advise.

Connecting UCS 6248 FI to N5K-C5548UP
hi,
How do i connect UCS 6248 Fabric Interconnect to N5K-C5548UP? do i need to use FCoE or vPC as i will have multiple SAN connected (using FC) on FI.
Please suggest best possible solution where i have minimul cabling hedache & can optimise physicl ports on N5K.
Regards
MaheshHi Mahesh,
vPC for FCoE uplink and / or unified uplinks is not supported at this time.
vPC only for pure ethernet uplinks still works the same way.

Have you read through the UCS Deployment Guide? I would suggest starting there. After you're familiar with the options we can discuss/recommend further.

I'm trying to build a config for a Nexus N5K-C5548UP-FA that will have a mix of FCoE and native fibre channel ports. What licensing do I need to purchase for the chassis to support this functionality? I'm not anticipating that any of the FC connections will be to other MDS appliances if that matters.
Specifically, when do I need these:
N55-8P-SSK9
N55-48PF-SSK9
N5548-FNPV-SSK9
thanks,
dsCurrent FC FCOE licensing model on N5K is honour based.which comes in increment of 8.
(N5K-8P-SSK9) 8 port FC license .
However future model is going restrict on port based lcienses.
After installing N5K-8P-SSK9 license file which is called storage protocol service license.
you would see
"show license usage" output show as
ENTERPRISE_PKG Yes - Unused Never -
FC_FEATURES_PKG Yes - Unused Never
N55xx-FNPV-SSK9 is only for FCoE NPV mode, not for FC NPV mode. If you'd like to run FC NPV mode you need the Storage Services License, this license also includes the FCoE NPV license.

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

Hi, I would like to know how many maximum FC ports can one have on a Nexus 5548 (N5K-C5548UP) without any expansion module? I have the FC_FEATURES_PKG license installed.
Cisco Nexus 5548UP Switch
The Cisco Nexus 5548UP (Figure 2) is a 1RU 10 Gigabit Ethernet, Fibre Channel, and FCoE switch offering up to 960 Gbps of throughput and up to 48 ports. The switch has 32 unified ports and one expansion slot. -
we are currently evaluating solutions for our storage upgrade.
we required 10GbE connection from storage to our servers.
there are 2 proposals that uses nexus switch.
1 uses nexus 5548 while the other one uses 3524.
i understand that 5548 is of a higher grade than the 3524.
i have 7 dell servers that will be connected to the switch using 10GbE NIC.
which nexus switch is more suitable for my environment.
7 servers -> 2 10GbE iSCSI switch -> 1x iSCSI storage(20TB)Well...you're on a Cisco forum, so we'd be remiss in not recommending Cisco gear.
The Nexus 5548UP is around 17k for the base model without any special layer 3 licenses.
http://www.softchoice.com/catalog/en-us/hubs-switches-cisco-nexus-5548up-switch-managed-N5K-C5548UP-FA-HV7684
If you don't use layer 3 on the Nexus (which I wouldn't), they've got pretty good port density for the cost. NXOS takes little bit of getting used to and, for us, the copper SFPs have been a royal pain in the ass, but otherwise, they're pretty solid devices. -
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,

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:

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:

Nexus 5548UP and GLC-LH-SM showing sfpinvali
Hi gurus, have just received a 5548UP and when a 1GB GLC-LH-SM is inserted into the system it shows as being invalid.
Eth0/1 -- sfpInvali 1 auto 10G 1/10g
4 different SFPs have been tried in numerous interfaces on the system. I have also upgraded the software to 5.0(2).
And I have tried setting the speed to 1GB on the interface.
Any ideas on what simple configuration task I have missed?
LPHi,
I've the same issue with GLC-T 1Gbps SFP tranceiver and NX-5548UP with L3 Daughter Card.

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.

FI 6248 Nexus 5548 Port-channel problem
Hi all
I have a strange behavior between 2 FI and 2 nexus 5k configured as VPC , From a remote location and from my desktop I can ping odd ip and not even , from an other desktop in the same LAN the reverse, for both the tracert are good.
The only solution is to shutdown ports 1/1-2 on nexus A or FI A and in that case both desktops can ping both IP.
All seems OK, no log error , no error on interface , I give below some commands
What thing to know is that the nexus b has a L3 card , not the Nexus A , In fact I am waiting for a spare L3 daughter card.
On both NexusI have such configuration and status

Any ideas, A configuration I forgot on FI ?
Regards .In fact in the probem I described the path is Esx -> FAB A - > N5K-A (for layer 2) -> N5K-B (for L3) -> routing to the LAN
And what you told me is that such configuration is not supported with VPC configuration , so I need to wait to receive the L3 card for the N5k-A. and check later if I have the same problem.
thanks
