Configure DNS on switch

[Service Informatique]

Hello and sorry for my english,

just little question, I have 4 DNS servers to set on switchs : 10.4.0.1 10.131.0.1 10.4.0.2 10.131.0.2

if there is a difference if i put DNS like this : 

ip name-server 10.4.0.1 10.131.0.1 10.4.0.2 10.131.0.2

and like this : 

ip name-server 10.4.0.1
ip name-server 10.131.0.1
ip name-server 10.4.0.2
ip name-server 10.131.0.2

thanks a lot

depends on the device, both should work.

Hello,

No apologies needed - your English is perfectly okay!

There is no difference between the two forms of the command. The second style (one DNS per command) will automatically collapse into the first style (multiple DNS per command):

r1(config)# ip name-server 1.2.3.4 2.3.4.5
r1(config)# ip name-server 3.4.5.6
r1(config)# do show run | i name-server
ip name-server 1.2.3.4 2.3.4.5 3.4.5.6

This was tested on an IOS-XE 16.12.

Best regards,
Peter
