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.

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.

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 am looking to see if Nexus 5596UP & Nexus 2248TP GE compatible with SFP-10G-SR? The reason is because a consultant was hired on to "design" the network layout and has decided to purchase Cisco SFP+ Copper Twinax Cables which have a 10M limit. A small handful of the Data Center racks are 10-15M away... just out of reach of the Twinax. I would prefer NOT to move the LAN row so that it is more centered in the room. Can I use the SFP-10G-SR to connect the 2 switches (5596 & 2248) together? This SFP has a 26M reach on standard 10gig fiber, the small cost increase per connection is of no concern.

View 4 Replies View RelatedI 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?

View 10 Replies View RelatedWhen 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.
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?

2) If yes, then what will be the configuration. Will it be similar to link Aggregation with Catalyst 6500 Neighbor Switch.
How will I know if my catalyst and Nexus switch supports Ethertype 0x05ff. This is for the beacon probes sent out by our ESX Servers.

View 11 Replies View RelatedWe have connected a single F5 box with dual links to 2 different Cisco Catalyst switches using 802.1Q trunks. F5 is configured with RSTP mode and on Cisco Switch RPVST+ is configured.STP root bridge is hardcoded on the Cisco side. Loop Guard is globally enabled.On F5 STP link type is Auto, STP Edge port is disabled since that port is connected to the cisco switch.When we are failing over the F5 primary link to the secondary link we see 'Loop Inconsistent' on the cisco switch and things dont work after the failover.We have tried configuring the F5 as STP passthrough but that doesn't fix out the issue.I have checked out the forums and found out following recommendations
1. Configuring MSTP bw F5 and Cisco for better compatibility (Not possible from Cisco side because of a major change in large production setup)
2. Configuring VSS in Cisco switches (not possible due to hardware limitation)
3. Connecting F5 using single links to each switch (redundancy compromised)
I am wondering that on which default vlan does the F5 STP instance0 sends the STP BPDUs ? the term used on Cisco side is native vlan and others use PVIDs; that F5 default vlan should match the native vlan on cisco trunk side.

View 3 Replies View RelatedI've inherited a network. It looks to have been setup as 10/100 originally, using Netgear FSM726S switches with fibre connecting the switches. The fibre to copper conversion is mainly achieved with 10/100 media convertors rather than GBICs - not sure why - though there are some GBICs in use. Some of the "key" switches have been upgraded to Cisco Catalyst 2960G switches, but nothing else has been touched, so most of the network still runs at 100MB.
