Re: [c-nsp] Nexus 7k Upgrade Path

Re: [c-nsp] Nexus 7k Upgrade Path

I’ll be honest I was pretty confident after reading the config guide on the website. This was going to happen this weekend but I wanted more time to prepare. The config guide does say ‘one command does it all’ which sounded great! I wasn’t aware of some of the issues people have seen such as

Re: [c-nsp] N77k and IPv6 traffic through SNMP (bug CSCuy92828)

Hello, We experience the same problem with our Nexus 9k switches that we have. The OID returns some kilobits of traffic which in reality is much more. The version of NX-OS is 7.0(3)I2(2d) I don't have any news regarding this fix which is very annoying and I don't believe its HW limitation
