DHCP update DNS record on IOS 15.2(4)E5 on C3750x

[DrakarBarna]

Hi,

This question has been post several time before but here my problem.

I find couple of documentation how to configure the DHCP service on a C3750x running IOS 15.2(4)E5 Universalk9 version.

On of the most complete one I find was https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dns/configuration/15-mt/dns-15-mt-book/dns-dyn-dns-supp-ios.pdf

In this documentation, I should be able to do what I want but when it come to configure the DHCP scope to update the DNS server, the command "Router(dhcp-config)#update dns both" is not available.

In the switch configuration, the DNS server and Default Domain are properly configure.

Any input ?

maybe you need to activate a higher image/license level?

Use Cisco Feature Navigator to find information about platform support and Cisco softwareimage support.

Thanks.

According to CFN, my IOs version is not exactly the right one.
