Most of the warring clans are using arms to fighting each other in Makuach Payam, Bor County.
The people feared that the influx of riffles in to the civilian population has led to an increase in conflict.
Last week, one person was killed and another wounded during a retaliation clash between the Koch and Deer clans.
Residents have blamed government for failing to resolve the issues between the two clans peacefully to enable the people to stay in harmony.
In January, two people were killed after violence erupted between Koch and Deer communities in Bor County with two police officers being injured as they were on a mission to intervene between the two rival clans in Panyangor area.
The two clans are said to be having a protracted rivalry over land ownership and the two communities are fighting over the ownership of Nomrier cattle camp.
It is unclear what caused the fighting, with a variety of reasons given by local people, including a land dispute going back to 1920s during the Anglo Egyptian rule.
Two people were arrested from Deer community in 2012 after they removed the border iron (point) demarcated during the British and Anglo Egyptian rule in Sudan during the construction of road connecting Bor with Malakal in 1940s.
However, other local people said the fighting was a retaliation made by Deer youth following the death of one of their members when the two sides clashed during a public dance last year 2012.
The fighting in January was between Kongdia of Koch and Wunchuei cattle camps of Deer.
This year South Sudan army has been helping in solving tribal conflicts to reduce cattle raiding, children abduction and creating peace among the local people.
Disarmament forces were sent to 11 counties Jonglei since March 2012 and are still on the ground and have so far collected approximated 18,000 firearms.
