Network control commands

AeroLab’s net commands allow you to simulate problems in inter-node and inter-cluster networking.

Block a port

Block node 1 in cluster dc1 from talking on port 3000 to node 2 of cluster dc2; simulate packet loss through drop instead of reject.

aerolab net block -s dc1 -l 1 -d dc2 -i 2 -t drop -p 3000

List network blocks

aerolab net list

Unblock the previous network block

aerolab net unblock -s dc1 -l 1 -d dc2 -i 2 -t drop -p 3000

Redo the network block, then trigger random packet loss

Same block as before, this time randomly dropping 3% of all packets

aerolab net block -s dc1 -l 1 -d dc2 -i 2 -t drop -p 3000 -M random -P 0.03

Remove the network block

aerolab net unblock -s dc1 -l 1 -d dc2 -i 2 -t drop -p 3000 -M random -P 0.03

Implement packet loss or packet latency

Switch	Meaning
s	Source cluster name
l	Source node list
d	Destination cluster name
i	Destination node list
a	action; set	del	delall	show
p	Latency
L	Packet loss count
R	Max link speed

aerolab net loss-delay -s dc1 -l 1 -d dc2 -i 2 -a set -p 100ms -L 10% -R 1024Kbps

Show netowrk loss rules

aerolab net loss-delay -s dc1 -l 1 -d dc2 -l 2 -a show

Delete all network loss rules between dc1 and dc2

aerolab net loss-delay -s dc1 -l 1,2,3 -d dc2 -i 1,2,3 -a del
