Configuring FET-10G-SR for NEXUS 5548/2248

Hey everyone-
I am a little newer with configuring switches and routers, and I have been asked to troubleshoot a FET-10G-SR in our NEXUS 5548 and NEXUS 2248. I am aware that the ports need to be configured to except FET parts, and I have tried using the "switchport mode fex-fabric" command to configure the ports, but the command will not work for some reason. Can anyone help me with configurations step by step to have these parts work properly? Any help will be greatly appreciated. Thank you!
Chris Hazell

It should normally work unless the port is not the proper type of has a configuraiton applied that's incompatible.
Can you provide the output for "show run int eth ___" and "show int eth___" (substituting your interface number for the "___") for the interface in question?
Also, if it's the first fex you are adding, you must have enabled "feature fex" globally.

Urgent help: L3 daughter card for Nexus 5548

Hi
We have 2 Nexus 5548 which is in one vPC doamin. All the servers are teamed to these switches
Requirement
We have to install New L3 daughter card.(N55-D160L3-V2(=))
I have gone through the Cisco websites and found that we have to do the following things
1. software version:
i Nexus 5548P Daughter Card (N55-D160L3)
Before installing a Layer 3 daughter card (N55-D160L3) into a Cisco Nexus 5548P switch, you must upgrade to Cisco NX-OS Release 5.0(3)N1(1b) or NX-OS Release 5.0(3)N1(1c) and then install the card into the chassis.

2. license:
Also in order to enable this module following license should present on N5k device:
LAN_BASE_SERVICES_PKG - it's free and lifetime.
https://supportforums.cisco.com/thread/2121574
I have 2 questions
1- In cisco documentation its says that these cards will be installed in the front where I/O module is and after NX OS 5.X they are hot swappable
Does that mean that no reboot will be required after installing this module (keeping in mind its the first time) so i am confused about the wording ???
Does license installation requires reboot??? in short if you are installing for the first time do we require a reboot ???? that is my main question
2- I have heard there is a known bug which keep rebooting the switch after installation of L3 card
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtl45495
has that been address in any version of license or NS-OS yet???
Thanks heaps guys
If the module is still offline when the requirements are met above, it could be a bug.(CSCtl45495) Try reloading the switch.

Nexus 5020/2248: Best Practice for DSCP-trust, verses DSCP-don't trust

We have several Nexus 5020/2248's for our server access to the network (approximately 1000 ports). On about 20 of these ports we want to trust the DSCP markings, since they are from out Cisco Unified Comm appliances (these are access ports). However, on all other ports (mostly access, so DSCP, but ~ 100 trunks so some are COS also) we want to "not trust" or essentially zero out any non-zero DSCP value.
Does anyone have suggestions on easiest/best method for setting the trust boundaries for Nexus 5020/2248s?
Note: vers 5.0(3) NS(1)
Thanks!

Hi
Before any other think I would like you to upgrade your WLC image to 7.6.130.0 & FUS to 1.9.0.0. FUS upgrade will require 30-40min downtime to your wireless.
http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.html
http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn76mr03.html
It tells me to disable 802.11a and 802.11b. If I go into each radio on 'Network' tab and disable these - NOTHING can connect to any SSID. So unless I've misunderstood something - this is a contradiction in the best-practice link I posted above,
This simply says, you have to disable radio band before changing QoS profile values. Once you change those value you can re-enable the radio band. :)
If I enable FT-PSK and PSK - for devices that support FT-PSK (which i'm under the impression is 802.11r) will these devices use that and for devices that don't they'll use 'regular' PSK? How do I know if my client is connecting using PSK or FT-PSK as both are enabled on the same WLAN.
Read these 802.11r post & you will understand how 802.11r works. There are certain client devices does not like PSK & FT-PSK capability advertise on the same SSID & may have connectivity issues. But most of the clients like iPhone, iPads,etc will connect without any problems.

"show client detail <mac_address>" should indicate if client connected over FT-PSK or PSK.

FCoE using Brocade cards CNA1020 and Cisco Nexus 5548 switches

All,
I have the following configuration and problem that I am not sure how to fix:
I have three Dell R910 servers with 1TB of memory and each has two brocade 1020 CNA cards dual port. I am using distributed switches for the VM network and a second distributed switch for VMotion. I have two of the 10G ports configured in each distributed switch using IP Hash. The management network is configured using a standard switch with two 1G ports.
The Nexus configuration is we have two nexus 5548 switch connected together with a trunk. We have two VPC's configured to each ESX hosts consisting of two 10gig ports in each VPC with one port going to each switch. The VPC is configured for static LAG.
What I am seeing is that after a few hours the virtual machines will not be accessible via network anymore. So if you ping the VM it will not work and if you get on the console of the VM then ping the gateway then nothing as well but if you try to ping another virtual machine on the same host on the same VLAN then it will work so traffic is going through the ESX backplane. If I reboot the ESX host then things will work again for another few hours or so then the problem repeats.
The version of vSphere I am using is ESXi4.1
Please assist I am stuck.
Thanks...

Here is the link for Nexus and Brocade interoperability Matrix

However I do not see Brocade 5300 listed in the table . It could be, interoperability may have not been tested by both vendors perticularly to 5300 type Model.

Nexus 5548 with FET-10G problem

hi,
i have single 5548 NX-OS 5.0.2N1(1) version connected to single fex 2232 via 4 X FET-10G. on the 5548 it is the first ports, at the 2232 it is at the last 8 ports.
after configuring appropriate FEX configuration i cannot see any link between them. when i am changing from FET to SFP-10G i get a link.
what could be the problem ?, do i need specific configuration ?
thanks,
Avi.

Hi,
Yes, you need to configure the 5548 ports as " switchport mode fex-fabric " before you connect the FET SFP's in the ports.
The FET is supported on N5k only when connected to the uplink of a FEX, however, the SFP will be non accepted
if the port on the 5k is not configured with:
"switchport mode fex-fabric"
Could you make sure that you have that configuration and that check again?
HTH,Please rate if it does.

Configure Nexus 5548 for native FC

hi
does anyone have steps on how to configure n5k for native fc to a storage controller and then map that to an interface running fcoe to a fabric interconnect say 6200 ?
appreciate any pointers

I hope this helps. For integrating UCS in FC NPV mode, you need to enable NPIV on the N5k (feature NPIV)
Fiber Channel (FC) Ports on Nexus 5000
Cisco Nexus 5000 is a Cisco Data Center switch platform that supports conventional Ethernet, Storage Area Network (SAN) and Fiber Channel over Ethernet (FCoE). The switch platform has support for connection directly to native Fiber Channel (FC) SAN network with its FC ports. This is needed at least for now as most of customers' storages are still using FC or are behind FC network.
This post will look at specifically on how to enable FC ports on Nexus 5500 (Nexus 5548UP and Nexus 5596UP) when we need to connect and integrate to FC network. In addition to that, we will look at some of the rules or restrictions that are worth to note based on the current hardware implementation when allocating ports on the switch for FC.
Cisco Nexus 5548UP and Nexus 5596UP are Unified Fabric switches that have 32 and 48 Fixed SFP+ ports, respectively. This fixed or built-in ports are unified ports which means that each of the ports can be used for conventional Ethernet, FCoE or FC. Out of the box, all of the 32 or 48 ports are "Ethernet" port type. As the name implies, with this port type, the port are ready for us to be used as conventional Ethernet port or for FCoE. Remember that FCoE is basically transporting FC traffic over Ethernet, so we need "Ethernet" port type for FCoE.
In that case, what if we need to use some of the built-in ports for FC?
To use some of the ports as FC ports, we need to change the port type of the port(s) that we intent to use for FC connection. Here's an example of commands to change port type on the switch:
N5K(config)#slot 1
N5K(config-port)#port 41-48 type fc
N5K(config-port)#copy running-config startup-config
N5K(config-port)#Reload
As the above command example, we change ports 31 and 32 from the default "Ethernet" to "FC" type. Similarly, to convert back from FC to Ethernet port type:
N5K(config)#slot 1
N5K(config-port)#port 41-48 type ethernet
N5K(config-port)#copy running-config startup-config
N5K(config-port)#Reload
Note: Refer to this Cisco's Command Reference document for further detail of this command: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/command/reference/layer2/n5k-l2_cmds_p.html#wp2326019
You might surprise that there's a reload command in the end? Yes, you need to reload the entire switch to convert port type. So...one of the important notes here is that, as much as possible, convert the ports before the switch is in production.
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:

Besides the fixed ports, each of the switch model have slot for expansion module for increasing the port density. The number of slot is 1 for Nexus 5548UP and 3 for 5596UP. For supporting FC, the following modules are available to choose from:
- Fibre Channel plus Ethernet module that provides eight Ethernet port and eight native Fibre Channel ports.
   The first 8 ports of this module is Ethernet port and the remaining 8 ports are FC ports. The location of Ethernet and FC ports are indicated with different colors.
http://3.bp.blogspot.com/-46A5Xu-iy3g/UALOGhdiW-I/AAAAAAAAAF4/DuhCP59VX54/s1600/Nexus+5000+-+Module2.PNG
- Unified port module that provides up to sixteen Ethernet ports OR up to sixteen native Fibre Channel ports
   This is unified port, similar to the fixed or built-in ports whereby it's up to us to use the ports either for Ethernet or FC. Probably you only want to use some of the ports or even the entire module for FC.

There is a java utility that can take an XML file that you have generated from an fmb file previously and compile it back to an fmb file.
Its called frmxml2f.bat. You'll find it in $Oracle_home/bin

Install pbr feature nexus 5548

I am in need of Policy Based Routing for a new project. At my core I have a couple of Nexus 5548s clustered together. I go into configure terminal and run the command "feature pbr" and the return is invalid. So I check the license with the command "show license usage" and I get the following output:

EEM on Nexus 5548

Hi all,
I'm new to EEM and we are investigating using it to solve some issues that we are having, However, I can't seem to find any definitive information which tells me whether EEM is available in the nexus 5548 switches. Can anyone here help to confirm if this is the case? If not yet avalable for the 5548s, are there any indications as to when it might become available?
thanks,
Ram

Might want to try the 6.0(2)N1(2) and later code. I have it loaded on a N6004 and EEM is available there. It is of course the NX-OS flavor of EEM but it is there.

C220 M4 w/ VIC1225 and Nexus 5548

I have four UCS C220 M4 servers that each have a VIC 1225 and are connected up to a Nexus 5548. I have set them to trunk ports and have set the appropriate VLANs in ESX and the portgroups. I can ping the gateway and other hosts on the network, but for some reason I can't ping any of the other C220 M4 servers that have a VIC1225. All of the C220's can ping other devices on the network, but not each other. Is there some setting I need to modify on the VIC or switch? Currently the VIC is running as Classical Ethernet mode.

There is no special configuration to make connectivity work in the rack servers, I assume these servers are in standalone mode and not integrated with UCSM.
What L3 device is doing your Inter-Vlan routing? Is it the N5K these servers are connected to or there is another device doing this job? If it is the N5K, are all the servers in the same network segment? I mean, is there a single SVI or multiple? can your Nexus 5K ping each of the servers?

Creating VPC's between 2 NExus 5548's

I am just about to setup my 2 Nexus 5548's in the
lab for VPc. I see that I have to setup an etherchannel using 2 10 gig ports for the Peer link and
I also have to setup a Peer keepalive.
Do I also have to burn a 10 gig port on both switches for this keepalive ?
I dont have any 1 gig ports on these switches.
Any help would be appreciated.
Cheers
Dave

The best way is to connect the mgmt0 ports to a CORE switch for out of band management. Also, when you configure the vrf context management, make sure you specify a route to the management subnet via vrf management.

Connecting IBM v7000 to Nexus 5548

IBM V7000 with Nexus 5548UP and Nexus 4000 Design/implemetation guide
Hi Guys
I have a question in regards to connecting IBM v7000 directly to Nexus5548.
CAN WE DO THIS?
Our current setup is IBM v7000 -> MDS 9124 -> Nexus 5548.
But our MDS 9124 are out of warranty now and we need to take them out of production. And only way we can do this is if we connect our IBM v7000 fibre ports directly to our Nexus 5548.
Can someone please point me to the right direction any knowledge base articles etc.
Thanks Heaps

NX-OS firmware Upgradation in Nexus 5548 with Enhanced vPC with Dual Active FEX

Hi All,
Please tell me how to do "NX-OS firmware Upgradation in Nexus 5548 with Enhanced vPC with Dual Active FEX" without downtime for FEX.
The Server are connected to FEX.
Attached the diagram.

Hi,
If the 5500s are layer-2 with vPC running between them than you can use ISSU to upgade.
here is doc to follow:
ISSU Support for vPC Topologies
An ISSU is completely supported when two switches are paired in a vPC configuration. In a vPC configuration, one switch functions as a primary switch and the other functions as a secondary switch .They both run the complete switching control plane, but coordinate forwarding decisions to have optimal forwarding to devices at the other end of the vPC. Additionally, the two devices appear as a single device that supports EtherChannel (static and 802.3ad) and provide simultaneously data forwarding services to that device.
While upgrading devices in a vPC topology,you should start with the switch that is the primary switch. The vPC secondary device should be upgraded after the ISSU process completes successfully on the primary device. The two vPC devices continue their control plane communication during the entire ISSU process (except when the ISSU process resets the CPU of the switch being upgraded).
This example shows how to determine the vPC operational role of the switch:

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 suggest

Hello,
Please see attached config for both Nexus 5548. I dont have Catalyst 4500 but below is simple config what I applied:
Both Catalyst 4500
interface gig 3/48
switchport mode trunk
switchport trunk encap dot1q
On Nexus 5548 Port 1/3 is trunk
