I have a big doubt. Can I connect a LAN switch (i.e. 2960, 3560 or 3750) to a couple of Nexus 2000 FEX (i.e 2232P or 2248TP) and have a Port-Channel or vPC with STP active and several VLANs through this Port-Channel? Or Can I only connect servers to these N2K FEX?

if vPC is supported between a single 2232PP FEX and two 7000 switches running 6.0(1)? I have been researching this for an implementation I am doing for a client and was able to determine it was not supported with earlier versions of 5.0 when the FEX is connected via vPC as I described above, but I can't find anything related to version 6.0(1). I have done this for other clients with 5000 and 2000 switches, but I don't have too much experience with 7000 switches.

View 3 Replies View RelatedI am designing a network for my client where I have to implement a 10 Gig end to end connectivity. The major factor of concern from my management is about scalability (space to include more 10Gig servers as the nodes grow up). I have suggested Cisco 5596UP with 2232 PP as this gives ample amount of 10Gig ports. The setup has to be implemented across 2 different datacenters located 40 Kms apart, connected with 10Gig DC Interconnect.
I understand that Cisco Nexus 2232 is a Layer 2 Only switch and would need to communicate with parent 5K switch very frequently. Is it necessary to have the 2K and 5K pair in the same datacenter or in proximity? Is it possible to have the SFP uplinks connected to the DC interconnect? Because we have two datacenters located 40 Kms apart and having 1*Layer 3 - 5K switch at DC A with Layer 2 - 2K nexus Switch at DC B will be cost effective. We do require more 10Gig ports and not much requirement on Layer 3 usage. What are the type of communication that would be much frequent between 2K and 5K?

View 9 Replies View RelatedConfiguration details: I have 2 nexus 5K switches and both 5K is connected to four 2960 access switches in each floor through fiber(shown in the attached picture). I have configured each VPC for each floor and portchannel configuration on 2960s switch to communicate to 5K switches. Now I am not able to communicate PC 1 connected in 1st floor to PC2 connected in 4th Floor.
I have attached topology map of my infra and the configuration files also. 1st floor switch and 4th floor swich have same configuration except IP address and switch name.
We recently had a pair of Nexus 5k switches setup in our network. We had professional services handle the initial configuration but they weren't able to setup config sync for us. Each Fex is connected to each 5k, so we need a switch-profile to maintain a consistent setup on our interfaces. I went through the process in Configuring Switch-Profiles, but when I check the status of the peer, it says not reachable. [code]

We would like to add another Nexus5k to this topology. However, it has to be a zero downtime infrastructure add-on. When setting up the keep-alive, peer-link, vPC and vdc domain, will there be any upset in network traffic on the current N5k?Also, are the Nexus5k configurations synchronized or are they independent from one another? Before setting up the new 5k, should i configure it to teh 6509's, and vPC's to the Nexus2k's before setting up peer-link?
My network consist of that network device. cisco catalyst 3750 with stackwise, 2xnexsus 5000 series and servers.servers connected to nexsus switch. nexsus connect to 3750.
Each server have two link, one of them connect nexsus1 and other connect to nexsus2 switch.(same traffic) each nexsus have one link to 3750. At 3750 the nexsus link configurate etherchannel. but the flapping occur at 3750.
i understand that at 2 nexsus link have the same server source mac address so the flapping occur at 3750. how i solve this problem?
Trying to find some documentation as to whether there are any other steps for inserting this new module in our N7K. We have 2 blades in already and 2 Sups in 5 & 6. I'm assuming its like the 6500s, where we just slide it in and the OS configures the global parms for it and the default VLAN.

As per my understanding, Cisco Nexus 2232 can only connect to HP c7000 Chassis if we are using a Pass Through Switch in the HP c7000.

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.
