i have a nexus 5k with a l3 card i'm not able to bring online
NX-OS is:5.0(3)N2 (1)
L3 card is:L55D160L3
i inserted L3 module several time with the same resul...if i perform a show module i see the card offline. At the boot switch show an error message:
L3 module is down due to a BTCM down..
I am setting up a new environment with 2 5548's and some 2248TP-1GE Fex's and Im running into an issue. I have the peer link and peer-keepalive link that appear to be good. When I configure the fex and vpc for the fex manually on each switch without pre-provisioning the slot the fex comes online and everything appears to be good. I can see all the ineterfaces when doing a sh int br and the sh fex detail shows all good. When I do the exact same thing but pre-provision the slot the fex stays in an offline state. Ive tried disabling the port(s) connected to the fex while configuring everything then enabling them but same thing. [code]

View 3 Replies View RelatedI 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 unable to get the N7K-M108X2-12L 10 Gbps Ethernet XL Module within our Nexus 7009 chassis to recognise the individual X2-10GB-SR transceiver modules. I have the same issue on another 7009 chassis.If I perform a 'show interface'. I get the following output saying SFP not inserted.
-Ethernet3/5 is down (SFP not inserted)
-Dedicated Interface
-Belongs to Po51
-Hardware: 10000 Ethernet, address: 7081.0599.d458 (bia 7081.0599.d458)
I also get the same result if I issue the following command. Are their any additional features I need to enable? or would this be a license issue?
Have already tried different X2-10GB-SR modules, reloading the card, re seating the card. [code]
Does Nexus 7K support Multiple VDCs sharing ports on a single line card. One of our cisco parnter engineers stated that cisco doenst recommend using same line card for multiple VDCs.The second VDC (Non-Default VDC) will be used four our Outside, and DMZ Segment, and to phyiscally segregate our Firewall from our Internal/Inside Core Switch without using a physical DMZ Switch.I know Cisco used the Nexus in this way in their PCI DSS 2.0 Compliance Document. Module is N7K-M148GT-11L

View 3 Replies View RelatedI have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.
I have a server with 4 ethernet ports, 1G, they are bonded together, two of them was pluged into cat6500 module WS-X6724-TX. now we have moved the two ports to the replace module WS-X6748-GE-TX.
I have checked server side, the bond configuration are same no changed. what is possible reason replace module will cause link offline? why "sh run all" give the port is shutdown?

View 1 Replies View RelatedDoes the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?

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.

I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:

I was reading a QoS walkthrough earlier to try to solve my problem and I noticed that in IOS, you can specify "match vlan" in a class map. This is not available in NX-OS. I'm not doing any routing on the 5K so I cannot match on ACL, and port where traffic is received is a trunk sharing other types of traffic I'd like to classify elsewise.
How can I match traffic on a per-VLAN basis?
