Nexus 5548 enhanced VPC capability

does the nexus 5548up running 5.0(3)N2(2b) support enhanced VPC? fabric VPC to the fex and vPC from the fex down to the host? if not, what minimum code version supports it? Thanks

You need NX-OS 5.1(3)N1(1) to run enhanced VPC.

Cisco Nexus 5548UP - Enhanced vPC

Hello,
We will be deploying a new Cisco Nexus 5K environment with 2248 FEX's.
The firewall in the environment (non-Cisco), only supports static Port-channels - i.e "ON" configuration and not LACP.
For redundancy we will be patching it into the environment in a topology where VLAN's are trunked and connected to two FEX modules as on page 2 of this document:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/mkt_ops_guides/513_n1_1/n5k_enhanced_vpc.pdf
Every example I've seen online uses LACP instead of a static Port-channel. My questions are:
Will this cause any issues in the event of port failure?
Is this best practice?
Are there any "gotchas" or caveats with this design?
Many thanks in advance.
Jacob

I always like to use LACP where and when I can. Some devices, like your firewall and vmware do not support LACP. As long as both devices are configured correctly and using mode-on, there should be no issues with this. I do not like mode-on for this reason, as it does not negotiate anything before bringing up the port-channel. Therefore just confirm it is configured as mode-on on both sides and you should be fine. This should not cause any disruption if one link fails, but I would test the configuration before putting this into production.

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:

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.

Nexus 5548 L3 daughter card flapping

Hi guys,
Anyone of you here that experienced the logs below on their Nexus box:
2011 Dec 12 06:24:45 GDCNXS5K01 %BTCM-2-BTCM_LOG_ROUTER_ERR: router card in slot 3 has internal link(s) flapped: router ports down: 0x1a108000 0x1a109000 0x1a10a000 0x1a10b000 0x1a10c000 0x1a10d000 0x1a10e000 0x1a10f000
I am getting this log at least once a day. Seems like it is shutting down the SVI of the box after the said log occured. Good thing I have enable vPC and I am able to access the NXS5K through the vCP keepalive link (mgmt).
I have two Nexus 5548, but only one is experiencing the said error.
Any inputs, suggestions would be greatly appreciated.
Thanks,
Edzel

We had this same problem this past weekend, only in module 2 on a 5596.
In our case, we had rebooted our primary Nexus and found the following message immediately preceeded the BTCM error you noted:
%$ VDC-1 %$ %NOHMS-2-NOHMS_DIAG_ERROR: Module 2: Bootup diag detected major event: Forwarding ASIC failure: Ethernet2/9 Ethernet2/10 Ethernet2/11 Ethernet2/12 Ethernet2/13 Ethernet2/14 Ethernet2/15 Ethernet2/16
We replaced the module. A "show diag results module 3" would probably show you the same thing. However, I don't think the error message will show up until you reboot.
If your flapping Nexus is secondary, you probably won't notice anything major, but if it is your primary, it would probably affect your routing.

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.

Enhanced VPC

Folks,
I do not have a 2232 in my lab to test this but do we need VPC1 in the below sample config? I think this is an error:
The sample config is for enhanced vpc with active-active fex senario.
nexus5500-sanA(config)#interface eth 101/1/1
nexus5500-sanA(config-if)# channel-group 1 mode active
nexus5500-sanA(config-if)# interface port-channel 1
nexus5500-sanA(config-if)# vpc 1
nexus5500-sanB(config)#interface eth 101/1/1
nexus5500-sanB(config-if)# channel-group 1 mode active
nexus5500-sanB(config-if)# interface port-channel 1
nexus5500-sanB(config-if)# vpc 1
I think the command in bold is not needed in a active-active Fex Senario. The Nexus switches will automatically find out if they are connected to the same host by the channel-group number.
Any assistance would be highly appreciated.

1) It is not EvPC in this set up. Just a regular vPC since the FEX is straight through.
2) It is true for the N5K but not N7K. N7K doesn't support vPC FEX.
Q1. On the server, it is a regular PO. on the FEX 1 and FEX 2, it will be vPC.
Q2. This will consider EvPC on the N5K ONLY. You will need to configure vPC for the FEXs and regular PO toward the server.
Q3. This is not EvPC. Just regular connections.
Q4. This is not EvPC, just regular connections.
To simiply vPC vs EvPC. vPC is also known as single-layer vPC, meaning the followings:
or
EvPC also known as dual-layer vPC and it looks like the following:

Vpc and enhanced Vpc

Hi,
I need to check if my nexus 5548UP is running Vpc or enhanced Vpc. Is there a command to verify that
I have NXOS 5.1(3)N2(1) running on this switch
Thanks
raj

As far as I know, there is no such a command to verify if you are running VPC or eVPC. The show commands for vpc are just "show vpc" or "show vpc keep-alive" etc..

Connecting IBM v7000 to Nexus 5548

20-Sep-2012 16:51 (in response to feisalb)
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
Sid

Dear prkrishn
I am working on the Data Center Solution between two Data Center, details underneath
DC 1 Site
1. 2 x DC Core Switch (Nexus 7009) - will be used for Servers, Application, IBM V7000, Database, etc.
2. 2 x Network Core Switch (Cisco 6509) - Handle Campus and Inter Building connection.
3. IBM V7000 (SAN)
DC 2 Site
1. 2 x DC Core Switch (Nexus 7009) - will be used for Servers, Application, IBM V7000, Database, etc.
2. 2 x Network Core Switch (Cisco 6509) - Handle Campus and Inter Building connection.
3. IBM V7000 (SAN)
With the above mention setup, can I configure FCIP between DC1 & DC2 using Nexus 7009? or I need FCIP capable Switch such as IBM SAN Switch (SAN06-BR), I was wondering if I can configure FCIP on Nexus 7009 DC Switch.
Hoping for your kind response at earliest.

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
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix7.html#wp313498
usually this table would show those models those have been tested and verified
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.

Vlan on Nexus 5548

I have 2 Nexus 5548, and those are VPC members. If I create a new Vlan (vlan 90) on each switch, will there any impact on the Peer link? Like peer link goes down or link flap ?
Thanks & Regards,
Manu

Hi Manu,
Creating new Vlan on both switches wont get any impact.
But be careful if you Vlan allow list on VPC peer link or VPC member link were you need to flow this new created vlan.

FCoE with Cisco Nexus 5548 switches and VMware ESXi 4.1

Can someone share with me what needs to be setup on the Cisco Nexus side to work with VMware in the following scenario?
Two servers with two cards dual port FCoE cards with two ports connected to two Nexus 5548 switches that are clusterd together. We want to team the ports together on the VMware side using IP Hash so what should be done on the cisco side for this to work?
Thanks...

Andres,
The Cisco Road Map for the 5010 and 5020 doesn't include extending the current total (12) FEX capabities. The 5548 and 5596 will support more (16) per 55xxk, and with the 7K will support upto 32 FEX's.
Documentation has been spotty on this subject, because the term 5k indicates that all 5000 series switches will support extended FEX's which is not the case only the 55xx will support more than 12 FEX. Maybe in the future the terminology for the 5k series should be term 5000 series and 5500 series Nexus, there are several differences and advancements between the two series.

Prime Infrastructure 2.0 and Nexus 5548, SSH credentials fail

Hi,
I'm having problem getting the Prime Infrastructure 2.0 to login with SSH to a Nexus 5548 to do an inventory. I get "Wrong Telnet/SSH credentials". But when I use the same credentials from another SSH-client it works fine. I also tested to SSH from the console of the Prime-server and that also works fine.
Any ideas???

I have PI 2.0 working against Nexus 5k's in two different installations. See below for an example (click to enlarge).
Have you put in an entry in both the login and enable fields (even though they are not separately required when logging in directly)?

Telephony Issues on Nexus 5548

Dear Viewers,
I have Nexus 5548 devices in one of my client data centers and i have one 3750 switch to which all of these Avaya voice servers connect.
The 3750 switch was initially connected through a L2 Link to a 6509 catalyst switch and the telephony applications were working correctly.
The problem arises when i move this 3750 layer 2 link to a Nexus 5548 (OS version 5.1(3)N1 switch. All telephony calls coming from the outside (External calls) are not working as required but the internal calls work as usual.
What is odd is that when i migrate this L2 link back to the 6509 switch, all works as usual. This is just a layer 2 connection and i am wondering why this is not possible.
The vlan is accepted on all relevant trunks. I also deactivated igmp snooping on this voice vlan on the Nexus 5548 thinking it would help but in vain.
Any ideas and suggestions are welcome.
regards.
Alain
