Nexus 1010 Appliance and DNS domain lookup.

[Marc Lariviere]

My N1010 Appliance is not able to do domain lookup, for example when I use PING command or COPY RUN FTP: command.

The result of the PING command is:

% Invalid host/interface <hostname>
% Bad IP address

The DNS config of the N1010 is:

ip domain-lookup
ip domain-name <private domain>

ip name-server <x.x.x.x> use-vrf management

I also tried with this config, but it's not working:

ip domain-lookup
ip domain-name <private domain>

ip name-server <x.x.x.x>

The version of the NX-OS is 4.2(1)SP1(2)

Is there something missing or bad int the configuration ?

Help me please !

I finally opened a TAC case.

Here is the TAC answer:

CSCtl79715 documents this issue on the Nexus 5000 platform which shares a common code base with Nexus 1k/1010 products.  I have opened CSCto42374 to have the fix ported into the Nexus 1k/1010 platforms.

Workaround from TAC:

conf t
vrf context management
   ip name-server 172.18.1.1

SV14# ping calo-dns-ns2.cisco.com
