Notice that the local interface is 126.96.36.199, this is really strange.
MDS9216i# sh ip int mgmt0 is up Internet address is 10.193.136.43/24 Broadcast address is 255.255.255.255
- is the address 10.193.136.43 reachable ?
- are NTP packets being exchanged - debug ntp packets
This is a Cisco MDS, no debug ntp packets, but debug ntp errors and debug ntp Info. It says update ack.
