I have One UCS 210M2 server and two Nexus 7K.We want to configure portchannel(etherchannel) UCS two NIC card and connect to each nexus 7K.Is this design supported, connecting UCS port-channel on two nexus 7K? we dont have 5K or 2K switches.What configuration required from Nexus 7K to achieve this vPC directly with UCS 210M2 servers?

View 3 Replies View Relatedwe are planning a Nexus datacenter project with this layout:Our experiences with Nexus switches are not so large until now and the manuals are very extensive.Both N5K´s should be connected directly with all 4 N2K switches. I did not find a layout like this in the manuals. Only a design,where only 2 N2K are connected to one N5K, with this fex config:Now I´m not sure if it is right to make a config like this with the same slots and fex´s or with different slots and fex´s.

I have multicast routing setup between two Nexus 7K's.These Nexus 7K's act as the distribution layer and they connect to 48 different 4507 access layer switches (VPC) and 3 6509 core layer switches.The 4507 swiches have two supervisor modules. One acting as active and the other as hot standby. Let's assume that multicast is working on the active module. If I pull out the active module the hot standby takes it's place. This is where multicast stops working on the switch.How can I get both Nexus 7K's to work with multicast at the same time. Here is an example of show ip mroute from both Nexus 7K's:note that DR02 has a lot more entries in the routing table. Is this working as designed?
DR01-C7018# sh ip mroute

I am trying to determine why hosts off our Nexus 7010s are being picked up in UT. Since LMS 4.0.1, UT should be supported on these devices.When adding the Nexus devices to DCR, provide the netadmin SNMP RO credential.When other SNMP RO credential is provided, user tracking will not collect end host data.I think I have this setup correctly as the device center test passes when cehcking snmp ro credentials.Our 7010s are running NX-OS 5.0(3) - earlier than the recommended version - might that cause issues? We are not using VRFs other than the default and management.
Here is my snmp section:
sh run | sec snmp

I was trying to get Netflow setup on one of my 7K VDCs and ran into a problem. While netflow data was reaching the collector, IP src/dst information was not appearing in the analyzer tool. I could not see any information about conversations. So I contacted the company that makes the collector/analyzer and the directed me to a blog on their site and told me to setup the 7K exactly as it is described in the blog post. I did and a bit later the ip src/dst address information appeared. So the only difference between the two configurations was that in the first case I tried to define a record and in the second case, no record was defined and instead the orginial-netflow parameter was used in the "flow monitor" section. [code]
I referenced the document "Cisco Nexus 7000 Series NX-OS System Management Configuration Guide,Release 6.x", Chapter 19 - Configuring NetFlow.It's clear to me that I didn't do something right in defining my own record since that's really the only difference between the config that worked vs the config that didn't. However, the documentation I referenced doesn't really provide useful information about how to create a record (above and beyond what I can already see by typing '?' at the CLI).
For example, the "match" command makes no sense to me. Usually when you have a match command it is accompanied by some sort of ACL. In the "flow record" section a match command would be something like "match ipv4 source address" but that's it. What does that mean? Match anything that has a IPv4 source address?? That doesn't make much sense. The collect commands are equally as bewildering. If I want to define my own record (and not use the original-netflow parameter) what do I need to do in the "flow record" sub-configuration to get Nexus to send ip src/dst information to the collector (which, I would think, is basic information to send - what good is netflow data without it)?

View 6 Replies View RelatedWith most of my Layer2/Layer3 switches, I'm accustom to giving them a SVI on my management VLAN, and calling it a day. I can't find in the Cisco Nexus guides how to do something similar; everything points to the mgmt0 physical interface, which seems like I need to uplink it to an access port on another switch. Can somebody point me in the right direction for how to do give the Nexus an IP that I can ssh/snmp into it across a trunk for management? I must just be missing the keyword.. NX-OS is still quite a different beast.I see in the manual it says: "SSH has the following prerequisites: You have configured IP on a Layer 3 interface, out-of-band on the mgmt 0 interface or inband on an Ethernet interface."
