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.
(NTWK-SER-3400) #ping 220.127.116.11 ?
count The number of ping packets [ 1 - 100 ] that are sent to the target-ip-address.
df-flag Sets the Dont-Fragment Flag.
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.
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 18.104.22.168 ?
source Sets the Source IP Address, thorugh which route is traced.
