Cisco Switching/Routing :: Add 2 X Nexus 5548UP Switches At Site 1
Mar 5, 2013
I have 2 sites located approximately 30 kilometers apart. I will call them site 1 and site 2.The sites are connected by a Layer 2 1GB fibre connection.I would like to add 2 X Cisco nexus 5548UP switches at site 1 and connect these 2 X Cisco nexus 5548UP switches via GLBP
I would then like to add 2 X Cisco nexus 5548UP switches at site 2 and connect these 2 X Cisco nexus 5548UP switches via GLBP.I would then like to connect the 2 X Cisco nexus 5548UP switches at site 1 and the 2 X Cisco nexus 5548UP switches at site 2 via GLBP.

The best option for load balancing between 2 X Cisco nexus 5548UP switches located at one site and connecting to 2 X Cisco nexus 5548UP switches located at another site.
The sites are connected via a 1GB fibre connection. I am unable to use GLBP until GLBP is supported in further software releases.

I have followed every piece of cisco documentation I could find on this and I still can't get vPC configured to actually work. The VLANs stay in a suspended state so no traffic flows across. Below is my configuration:vrf context management ip route 0.0.0.0/0 10.86.0.1vlan 1,vlan 86 name I.S_Infrastructure,vpc domain 1 role priority 1000 peer-keepalive destination 10.86.0.4,interface Vlan1,interface Vlan86 no shutdown description I.S._Infrastructure ip address 10.86.0.1/24,interface port-channel1 switchport mode trunk vpc peer-link spanning-tree port type normal,interface Ethernet1/1 switchport mode trunk channel-group 1 mode active,interface Ethernet1/2 switchport mode trunk channel-group 1 mode active ,interface Ethernet1/3,escription Connection to Mgmt0 switchport access vlan 86 speed 1000.

I have a Nexus 5548UP that would be managed by two organizations. Is it possible to set IP addresses for mgmt0 and an SVI (or an L3 interface) without using the L3 daughter card? I don't want to route between VLANs, just to separate management traffic.

I'm trying to get a node in SVI1 on VRF1 to speak to another node in SVI2 on VRF2 to reach each other. After hours of failure, I went to outside resources. Everything I read on the internet says it's not possible on this platform and at least one TAC engineer seems to agree.
I just can't believe such a high-end data center switch is not capable of handling such a basic feature.

We currently have an environment with a 4507 as the core switch connected to four stacks of 3750e's in the wiring closets. A pair of Nexus 5548UP's also hangs off the 4507, but at the moment more or less dedicated to a certain purpose..The 5548UP's have the L3 daughter card installed.
My question is: Can a pair of Nexus 5548UP's do a C4507's job? Would we be able to decomission the 4507 and replace with the existing 5548UP's + FEXes?

I can't find anywhere whether it is possible to create a vPC domain with 2 Nexus 5548UP switches, where only 1 Nexus 5548UP has a L3 daughter card.

This past networkers I was at the Cisco booth discussing how the 2248 can connect to the 5548 and have server connectivity. It was told to me that now, as of a fairly recent NX-OS release, you can have the 2248 going dual-homed to both 5548 via VPC and then have a server connected to both 2248 and be in active-active mode. Is this correct?
When we first deployed our 5548 and 2248 we had to put the 2248 in a straight pin mode, where it only had connections to one 5548 and then the server would dual connect to the 2248's and be in active-active mode. I was told that this changed with an NX-OS release however documentation still seems to be fragmented on what exactly is the case.

How separate is the management interface on a Nexus 5548?
In context - what's the risk of having a layer 2 only Nx5K in a DMZ and running the managment ports down into an internal managment VLAN, to form peer-keepalive links and software upgrades.

I am looking to implement a QoS policy on a pair of Nexus 5548 UPs. FCoE is a factor here. I have created the following configuration and would like to get a few pairs of eyes to take a look at this for a quick sanity check.
How to make sure this config is valid. Also, I realize I'm applying an MTU of 9216 to all classes right now, this will be phased out incrementally.
class-map type qos match-all class-platinum
match cos 5
class-map type qos match-all class-gold
match cos 4
class-map type qos class-fcoe
match cos 3

I just received a Nexus 5548 to configure as the core of the Datacenter LAN. Is it true that the VRFs created cannot talk to each other??? I can't seem to find any documentation on how to do this and at least one TAC engineer half-heartedly believes it's not possible, either.
Basically, I'm trying to get an SVI in VRF1 to be able to talk to an device on another SVI in VRF2.
I can't believe this high-end switch, that is so capable in every regard, cannot handle this feature.

I'm seeing several error messages like these in the logs of my Nexus 5548UP switches.

I will say that these 5548s are serving as the distribution layer for a UCS chassis (2x 6120 FIs) but didn't know what kind of visibility the Nexus would have into that - the chassis keyword is what's alluding to this in my mind, and I'm seeing these messages whenever interfaces that connect downstream to the fabric interconnects are brought up or down.

In the existing network we have Cisco 2811 router connected to Corporate MPLS cloud. Cisco 2811 is connected to Catalyst 6509 switch(set based IOS with MSFC card). Along with that we have two Catalyst 5509. We are upgrading the access layer by replacing catalyst switches with Nexus 5548 & 2248.
For a purpose of testing I have connected 5548 & 2248. Created cPC and ether channels between two. SVI and HSRP configuredon 5548. I am terminating 2651 (test router) on 2248 port 101/1/1. On 5548 I have enabled EIGRP on vlans. I am unable to ping to 2651 from nexus switch 5548 and vice-versa. I can see both devices on CDP but I do not see eigrp neighborship formed.
What configuration should go in 2248 and 2651 in order to establish a connection between two? If test is successful then I will connect 2811 to 2248 during actual migration. I assume that in testing if it works for 2651 then it must work on 2811 router.

I have a pair of Nexus 5548UPs that have some high priority servers running on them. Servers are ESX hosts running Nexus 1000v's. Each host has multple connections in a VPC to both 5548s. We have been having intermittant ping loss and slowness of traffic to the VM's on these hosts. I was poking around trying to figure out what the issue could be and found that the peer-keepalive command was not set to send the heart beat across the mgmt0 interface. I would like to change this to point it accross the mgmt0 interface. Any tips or advice for me on making this change with production servers running on the switches? I do not want to cause any loss to any systems when I make this change. [Code] ..........

We have recently upgraded oor LAN and we are using couple of Nexus5548UP switches in the core with 2960 stacks as access switches. Each access switches stack is connnected to both core switches with link being port-chanels and VPCs. All is working fine, but our SolarWinds management platform (NPM) is being flooded with "Physical Address changed" events. Here is an example of messages:
NSW_Core_2 - Ethernet1/7 Physical Address changed from 000000003811 to 73616D653811
NSW_Core_2 - Ethernet1/7 Physical Address changed from 200B82B43811 to 000000003811
For each interface I have messages like these repeating.I am not sure what those messages means or if there is actually anything wrong. Performance of the network is good, there are no errors on any interfaces and I do not see anything related in the switch loggs.

Need clarification on the VPC with 5k and 2248 Fabric Extenders. My question is can each fabric extender uplink to two different 5ks, and at the same time, have servers connected to two both fabric extenders with a VPC.So basically, the server NIC will team with two different fabric extenders, and each fabric extender will connect to two different 5k's.

We are currently using two Nexus 5548UP's as our Datacenter Network Core. I have a pretty simple objective: I would like to enable Jumbo Frames on a single VLAN only(VLAN 65). This VLAN is used strictly for backups. I do not want to enable Jumbo Frames on the other VLANs(VLANs 1-10). Im not sure what the best way to do this is.....or if it is even possible but I am hoping to get some configuration examples.

I've been asked whether we can use HP-branded 10G SFP+s (P/N 455885-001) in Nexus 2Ks to provide 10G connections to HP C-Class enclosures. We've used HP-branded twinax, and Cisco-branded SFP+s and twinax, but we have a raft of HP 10G SFP+s sat in a store room gathering dust and now we want to save some money by not having to buy the Cisco parts to match.

Configuring OSPFv2 on a Nexus 5K switches, after configuring area 0 or area 10 it shows as 0.0.0.0 or 0.0.0.10 instead, I'm planning to uplink a couple of ASAs with OSPF enabled, just wondering if the area format showing will be a problem, is this how is supposed to look in the Nexus 5K? and will the 5K be able to form adjacensies with other non-Nexus devices that have area 0 and 10?

I have 2 NEXUS switches in VPC. When I create/delete a VLAN gets updated in the same switch, but the VLAN information does not get propagated to the neighboring switch. Revision number remains the same even if I modify the VLAN. Had also tried changing the VTP status to transparent mode & reverting it to client mode but no luck.Have double confirmed on the VTP domain names & password. However the same setup in different location which works perfectly fine.

According to Cisco, Nexus 1010 can host up to (6) Virtual Service blades. I can't find out how many Virtual Supervisor Modules and Virtual Ethernet Modules that make up one Nexus 1000v switches can be supported by each Virtual Service Blades. In other words, how many Nexus 1000v switches can be created with Nexus 1010 appliance?how to configure Nexus 1000v switches with vmware. without Nexus 1010, the standalone nexus 1000v switches was configured from vCenter as an OVF. But how to configure Nexus 1000v switches with vmware where nexus switches are hosted on Nexus 1010 appliance.

I am trying to understand what load balancing method is used on a port channel on a Nexus switch . I have a server connected by a VPC to two Nexus switches. The nexus switches are only acting as layer 2 switches. I have a 6509 connected via a upstream link that does all of the routing for my VLANS. If have a server connected to the Nexus switches and it talks to a server on my 6509 what load balancing happens on the Nexus going across VPC 27 which is a layer 2 trunk going up to my 6509. Is it done on layer 2 or layer 3 flows?
My Nexus shows the default load balancing configurations
Port Channel Load-Balancing Configuration:System: source-dest-ip
Port Channel Load-Balancing Addresses Used Per-Protocol:Non-IP: source-dest-macIP: source-dest-ip source-dest-mac

We are looking forward to implement IBM BladeCentre Swiches connectivity with Nexus 2k module.I would like to brief you about my network over as follows:
Coreswitch : 6513 ( Layer 3 switch + Spanning Tree root)
Nexus 5010 : Layer 2 switch
Nexus 2k 10G ports based module.
Currentl Solution : we want to connect the IBM Blade Switches (4) as demonstrated in the attached diagram which will be connected to Nexus 2k module as Ether-channel Access port.
Initially we been proposed by our vendor with this design and Now vendor is recommending us to connect the Blade switch etiher to Nexus 5k switch or directly to 6513 core-switches instead of Nexus 2k modules as they say Nexus 2k modules are only to connect the Edge devices .
We do not have ports available on Nexus 5010 to connect the cables from IBM Blade Centre Switches. Otherthan that, incase if we go ahead and connect the IBM Blade switches as access ether-channel access port with Nexus 2k module what are consequences we have to face realted Spanning tree or any other.

Connecting a legacy Nortel switch (425/450/470/BPS) to a Nexus 7000 via gigabit fiber? I have a customer trying to do it and they say that the connection never comes up. The support on the Nortel stuff is long since expired, so Avaya is not being particularly useful. Apparently Cisco says the issue is "fast link pulse to the BayStack to determine the capabilities of the uplink and the BayStack is returning all zeros." I have not verified this and actually have not yet gotten my hands on the Nexus side of things

I have a lot microbursts in my network and i looking 10G switches with big buffers. Which models have biggest buffers ? I think about 1-2U (nax 4U) switch with up to 60-100 10G ports. Something like nexus 3064 (he has only 9MB shared buffers AFAIK). Besides deep buffers i need also:
- trill or another ethernet ring topology like erps,eapsv2,
- Multi chassis LAG,
- virtual routers, policy routing
- dcb
- 40G interfaces will be plus

what is the difference between Cisco Nexus switches and the usual catalyst 3750 switches.I do understand the operating system in both these are different.
When will we suggest using Cisco nexus instead of usual Cisco switches? Also what interface does Cisco nexus like 5548 come with , is it both copper and fiber?
