Changing Control Packet Classification Using the Mangle Table
date_range
18-Nov-23
The NorthStar application uses default classification for control packets. To support a different packet classification, you can use Linux firewall iptables to reclassify packets to a different priority.
The following sample configuration snippets show how to modify the ToS bits using the mangle table, changing DSCP values to cs6.
Zookeeper:
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p tcp -sport 3888 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 3888 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -sport 2888 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 2888 -j DSCP -set-dscp-class cs6
Cassandra database:
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p tcp -sport 7001 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 7001 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -sport 17000 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 17000 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -sport 7199 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 7199 -j DSCP -set-dscp-class cs6
RabbitMQ:
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p tcp -sport 25672 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 25672 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -sport 15672 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 15672 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -sport 4369 -j DSCP -set-dscp-class cs6 iptables -t mangle -A POSTROUTING -p tcp -dport 4369 -j DSCP -set-dscp-class cs6
NTAD:
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p tcp -dport 450 -j DSCP -set-dscp-class cs6
PCEP protocol:
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p tcp -sport 4189 -j DSCP -set-dscp-class cs6
ICMP packets used by ha_agent (replace the variable NET-SUBNET with your configured network subnet):
content_copy zoom_out_map
iptables -t mangle -A POSTROUTING -p icmp -s NET-SUBNET –d NET-SUBNET -j DSCP -set-dscp-class cs6
To verify that the class of service setting matches best effort, use the following command on the NorthStar server:
content_copy zoom_out_map
tcpdump -i interface-name -v -n -s 1500 “(src host host-IP ) && (ip[1]==0)”
To verify that the class of service setting matches cs6, use the following command on the NorthStar server:
content_copy zoom_out_map
tcpdump -i interface-name -v -n -s 1500 “(src host host-IP ) && (ip[1]==192)”
