MSM765 SNTP Time Sync


This week we’ve been reconfiguring our MSM765 wireless controller and adding some new features for Students and guests to the School. With our old ZL WESM we were able to have a VLAN on the wireless network with an HTML based login, which allowed the students to use their own machines on the wireless network with their AD credentials. We wanted to replicate this setup on the MSM by using HTML-based user logins and still use their AD logins. We hit a problem when we tried to configure the Active Directory Authentication on the controller because the time on the controller wasn’t in sync with the 5400 chassis or the domain!

When we check Controller –> Management –> System Time, we could see the the time was incorrect, but there was no option to change it or specify an NTP server. The command ling reference for the controller (MSM7xx-CLI-RG-May09-5992-5933.pdf) gave a few clues on how to set the SNTP server and get the controller connected to our Windows time server

Connecting the terminal to the 5400 with the controller (MSM is in Bay I)

BGSCore(config)# services  I 2
BGSCore(msm765-application-I)> enable
BGSCore(msm765-application-I)# conf
BGSCore(msm765-application-I)(config)# ntp protocol sntp
BGSCore(msm765-application-I)(config)# ntp server 1
BGSCore(msm765-application-I)(config)# ntp server

The time sync’d straight away and made the connection to AD without a hitch
