We have two Cisco Nexus 5596UP switch.
We upgraded
n5000-uk9-kickstart.5.0.3.N2.1.bin (Fan speed %40) to
n5000-uk9-kickstart.5.1.3.N2.1a.bin (Fan Speed %60)
but 20% increased speed of the fans. What could be problem?

I have two Nexus 5596UP that will be connected together via VPC-Peerlink. From there I want to connect both 5596UP's to a 6509-VSS via VPC.The Nexus 5596UP's will be essentially layer 2 switches, all routing will be done the 6509-VSS's.
View 2 Replies View RelatedWhen I read Nexus 5K install guide , I found the follow :The Cisco Nexus 5596UP switch has the following features: # •48 fixed 1- and 10-Gigabit Ethernet server connection ports on the back of the switch AND The 48 fixed ports support 8-, 4-, 2-, or 1-Gbps Fibre Channel transceivers and 1- or 10-Gigabit Ethernet transceivers. Does these is a conflict ?The 48 fixed port on this switch support only 1- and 10-Gigabit Ethernet or 8-, 4-, 2-, or 1-Gbps Fibre Channel and 1- or 10-Gigabit simultaneously ？
View 2 Replies View RelatedWe 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 would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them.What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.

2. on pair of NEXUS 5596 running 5.1(3)N2(1a) with a Layer-3 module installed in both.When doing Enhanced vPC - connecting all FEXs dual-homed to both 5596 - how many FEXs can I have in total ?
I need to upgrade my core switches at one of our locations (two 7009s with dual sups) from 6.0.1 to 6.1.2. After looking through the release notes it appears that this will be a disruptive upgrade?how long should I expect for the disruption? Are we talking a 7009 boot cycle (10 - 15 minutes) or something longer?How many disruptions can I expect? I suspect 1 per chassis during the failover to the standby but I'd like to validate.Is there any compelling reason to upgrade the EPDL? From what I can see, again from the release notes, this is only necessary with F2 cards if I were to upgrade to Sup2s . I'm in a healthcare environment and this upgrade will be affecting one of our major campuses so the more info I can get to the managers the more accepting they will be for the disruptions.

We are currently using version 5.2(1) on Nexus7000 C7010, We want to upgrade to 5.2.4 is it compatible or any issues with this version?
I'm about to perform an upgrade on two Nexus 7010 switches per above. Can I directly upgrade or, do I need to go from version 4 to 5.x and then to 6??

View 3 Replies View RelatedThe Nexus 5548 is running 5.1.3.N2.1a and has the L3 daughter card (N55-D160L3)I have the EIGRP feature enabled. By the way, when doing a 'sh feature' four EIGRP features show up like this: [code] To create the L3 SVI, I go into config mode and attempt to type 'interface vlan 10'. but this doesn't work. These are the only options under the keyword 'interface':

I must be missing something simple but can't seem to see what that is. What do I need to do in order to create an L3 SVI on this 5548?
Interestingly enough I've seen about 3-4 posts with the exact same problem and yet not a single one is ever answered.. The task is simple:
"username USER password 5 SOMEPASS role network-admin"
It consistently outputs: "String failed to match token pattern at '^' marker." - always the carat is at the first character in whatever password I input. I've ensured passwords I input meet the conditions of "password strength-check" and I have also disabled this feature and repeated with numerous passwords to no effect.

Is there any challenge to upgrade core switch 6500 series from Nexus 7009 which runs NxOS, because i have 3750X series switches connected at distribution and access layer in my network topology??

View 1 Replies View RelatedCan nexus 5010 supports inter v lan routing , as there is no core switch and router available in current network.
View 2 Replies View RelatedWe have our Nexus as our default gateway (101.1) and the default VLAN1 is setup with two subnets 101.X and 102.X. The DHCP server is using a superscope setup to accomodate the overflow of devices requesting IPs on 101, so when 101 is consumed persons are able to obtain a 102.X IP address. The setup is basic on superscope. The issue is some times the routing to the firewall with a 102.X is not always 100%. Somedays all goes well and the 102 subnet is routed out to the firewall and its a good day. However, such as today a 102.X address is not routing as it did 24 hours ago. I am perplexed as to why this is behaving unpredicatable. Here is running-config for VLAN1 to show the 102 as secondary address to VLAN1.
View 2 Replies View Relatedyou find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.
View 6 Replies View RelatedI have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links. I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
1) Is it best to configure a separate Vpc VLAN i.e 1010
2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
I have a pair of 5548P switches with the L3 daughter cards installed. Using the base license as I just need RIP routing. I have the two switches setup and have the RIP routing feature enabled. When I "turn on" routing using RIP I do not get any routes from my existing L3 switch (3750). I probably don't have routing setup correctly. With the 3750 IOS, I just turned on RIP with the router rip command and added a couple of network statements. On the nexus I have run router rip {instance} and left it at that. I am not getting any routes from my 3750. The 5548s are using the management ports and are connected to my existing network with L2 trunks. Does any know of a setup guide for RIP? I have used the Nexus 7000 RIP guide but still can't get it to work.
