Environment : This article applies to Aruba Mobility Controllers running ArubaOS version 6.3.x and Above.
Starting from Aruba OS 6.3.x extended ping and extended traceroute functionality was Included which will better help to troubleshoot network issues.

count The number of ping packets [ 1 - 100 ] that are sent to the target-ip-address.
The default is five with standard ping, but you could send 100 with extended ping. If your network is having trouble periodically you could test this with extended ping.
df-flag Sets the Dont-Fragment Flag.
The Don't Fragment option does not allow this packet to be fragmented when it has to go through a segment with a smaller maximum transmission unit (MTU), and you will receive an error message from the device that wanted to fragment the packet. This is useful for determining the smallest MTU in the path to a destination.
packet-size The size in bytes [ 10 - 2000 ] of a ping datagram.
While the default is to send a 100-byte ping, with extended ping you could send very large ping packets. Perhaps your network is having trouble with large data transfers.
source Sets the source interface for a ping datagram.
The Vlan interface or IP address of the router to use as a source address for the probes. The Controller normally picks the IP address of the outbound interface to use. Useful to troubleshoot Vlan related issues.
Just as you can use the extended ping command to determine what kind of connectivity problems you're having, you can use the extended traceroute command to narrow down where the problem is happening.
(NTWK-SER-3400) #traceroute 74.125.236.135 ?
source Sets the Source IP Address, thorugh which route is traced.
