Cisco Switching/Routing :: Nexus 5020 - Fan Chassis Failed
Oct 24, 2011
I have an alert from monitoring system about: “ fan for this system is not in the NORMAL state”. In the switch I found that the problem is with fex 3, see below:
Nexus5020# sh env fex 3 fan
Fan Fex: 3:
------------------------------------------------------
Fan Model Hw Status
------------------------------------------------------
Chassis N2K-C2148-FAN -- failure
PS-1 N2K-PAC-200W -- OK
PS-2 N2K-PAC-200W -- OK
Technician said: fans appear to be operational, BUT the only thing that appears abnormal is STAT light is amber (not sure what it means).
Also, if I compare the temperature from module 3 with module 2 (which doesn’t have an alert) is almost the same, this is why I think the fan is working fine, since module 3 is not hotter that module 2.
What I can do to reset this fan (chassis)?

I have two N5K (5020) switches with NX-OS - 5.0(3)N2(1). These two switches form VPC domain: peer-link = 2*10Gb ports (1/17-18) and peer-keepalive link over managements ports.Also I have two HP servers with two 10 Gb ports on each server.Each server conected by one link to each N5K switch (1/9-10). N5K downlinks configured as access ports with LACP Active mode.There is only one VLAN (1).When "no shut" command entered on N5K access ports - ports going in "not connected" status, begin flap and then going in "linkFlapErrDisabled" state.In attach - "sh run" from N5K.

We have two Nexus switches in our network, one of them is Nexus5020 other Nexus5596UP. System image is identical on both switches 5.2(1)N1(4). When we try to setup VPC between these switches we see that all configured vlans on VPC peer link between Nexus switches are blocked by spanning tree protocol with message "Bridge Assurance Inconsistent, VPC Peer-link Inconsistent". We still can't solve this problem.

I'm trying to create a vpc between a Nexus 5010 and Nexus 5020 switch. I recently upgraded the software so they are running the same version. I connect get a vpc link. Is there something wrong with my setup? Is a vpc between a 5010 and 5020 even possible? They are connected using a pair of Intel X520's in 802.3AD teaming mode. [code]

Our customer is willing to have a Cisco Nexus 5020 to provide server connectivity and this Nexus would go connected to their core switch 6509. They are concern about Spanning tree compatibility between the Nexus and the 6509. Are they fully compatible for Spanning tree?

I have a customer who is having some issues with 5m passive HP twinax cables, 537965-001, with a Chelsio 10G NIC. Aside from NIC driver issue, if NX-OS recognizes this SFP+, should it be expected to work in a 5020 running 4.2(1)N1(1)? Whether Cisco has certified passive HP twinax cables? I have included output to 'transceiver details' to a Cisco twinax and the HP (WL GORE) cables.

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.

I have two different model's of GLC-T SFP's. One is PN 30-1410-02 the other is PN 30-1410-03. The -02 will not work in Nexus 5020 or an ASR-1000 router that I have, but works fine in my Cisco Wireless Controller. The -03 works fine in any device. My problem is when ordering, you can not specify the -03 they get ordered as GLC-T and none of my suppliers can assure me that I would get the -03.What is the difference between these two?

When transferring traffic between two VLANs my throughput rate seems to drop to about 1.5 - 3.0 megabits / second.
My setup is like this...
Two Nexus 5020 switches. (switch01 and switch02)
Two Nexus 2232PP fabric extender switches. (switch03 and switch04)
Two Dell R815s with Chelsio and Intel NICs. (host1 and host2)
The servers run Xenserver 6.0, but as part of testing with this I've tried installing RedHat 6.2, VMware ESX 5.0 (vsphere 5).
The issue occurs when using trunking and transferring data from one VLAN to another. Example...
VM1 is in VLAN401 with an IP address of 10.100.40.40. The VM is on Host1. VM2 is in VLAN402 with an IP address of 10.100.50.50. The VM is on Host2.
I've been using a network throughput tool called iPerf to test and I find that I can only get a throughput rate of about 3.0megabits.
If I switch VM2 to be in VLAN401 with an IP address of 10.100.40.41 I get a throughput rate of about 6.7gigabits/sec.
In the above scenario, I'm using a Layer3 interface on the Nexus 5020, but in production we use a Vyatta virtual firewall.
I worked with Citrix for about 3 months and that was a dead end.

Currently have a pair of 6509 chassis setup with VSS. Only have the Sup and two line cards in each chassis. Would like to replace with a new pair of 6504E chassis. Is it possible to fail one chassis at a time and migrate to the new 6504E?

why is not possible to put a WS-X4712-SFP+E - module into an R-E chassis?The module has the same connection to backplane as the WS-X4748-UPOE+E and this one works in a R-E chassis.I know the restriction of Cisco that the 4712 is only supported in 4503-E, 4506-E,4507+E and 4510+E, but why?Are there hardware-restrictions, is the backplane different?

We are preparing to install a new switching Infrastructure at one of our sites. We have decided that we want to have two separate chassis as a core. My original idea was to purchase 2 - 4500 chassis and install 10Gb and 1GB line cards in each and use STP and HSRP to load balance between the two cores.
We had also contacted a vendor for thier recommendations and they came back with 2 6500 Chassis running VSS. I reviewed what VSS was as I had never heard of it and it looks to me basically to be real close to the same thing as Stacking. I didn't really want to have stacked Cores because I would like to have the flexibility to be able to take one core out and update the software or image, reboot, and such without effecting anything on the network. I can do that with the non-VSS approach but it looks like that would be more of a problem with VSS.
My question is, how to use VSS with the 6500's? How to take one of the VSS pairs off line and not effect normal network operations?

Configuring a 4507R classic chassis with redundant Sup 6L-E? TAC told me the Supervisor 6LE was only supported on the 4507R+E or 4507R-E chassis but I have found in Cisco documentation several places that indicate that the Sup 6LE is supported in the classic chassis.

We have a backup sup 720 which has a 2 gigabit ethernet though port channel, to another chassis. Suddenly UDLD detected an error and got into err disable, then this err disable didn't let the interface set to DOWN, and created a switch loop, then our Supervisor reloaded. I'd like to know what could have caused this reload. In my opinion could have a been the switch loop, but also I've been checking from the output interpreter the show tech and might have been a bug, the only one that could match in IOS version 12.2(33)SXH, is this one: url...
We're going to disable err-disable next time I guess and recover the link manually, apart from that what could have made the sup for crash and reload?

Can any share some useful links on how this works and how to configure it? Do you still need to configure FHRP or does configuring redundancy take care of active/standby relationship between the ASR's?

I have 4x 3110x switches in a Bladecenter H chassis and the stack cables are connected so that they are in a circle (IE, SW1 connects to SW2, SW2 connects to SW3, SW3 to SW4 and SW4 to SW1). Each of the switches physical 10GE port is trunked to a 6509. If I pull a 3110x switch out, does this network connectivity? Theoretically it should not?

we have some pairs of 6509-VSS, which partially have old (no more officially supported) 6509-Chassis.All linecards in the VSS are the same (Sup 720-10GE-3C, 67XX).
We now bought some new 6509-E-Chassis and want to change the old chassis by the new ones in a ISSU manner, that means:
1. putting the partner, which chassis changes, in redundancy mode, switch it off, exchange chassis (old "Catalyst 6509", new "Catalyst 6509-E")
2. inserting the line-cards exactly in the same slots and connecting all cables
3. switch on the new chassis, witing to come up in VSS
I'm not sure of having to set the switch number for VSS (is that in the Sup?; configuration? or part of the chassis-memory?)
I've looked up cisco for some hints, but don't found anything.

I have been tasked to replace the existing Cat 6500 and 3750 switches by Nexus 7000 and Nexus 2000.I was told initially my boss plans to get 2 x Nexus 7000 and then eventually blow up to 4 x Nexus 7000s.For Nexus, is there a list of tasks / points that i need to consider for building the initial design?
Can i just link the Nexus 7000 like the following?
