Hello,
I need for my ISP (french ISP Orange) to set a specific 802.1q VLAN ID & priority for the DHCP request, and can't find a way to do it using my SRX340. I'm using firmware 22.1R1.10.
The ISP ONT is connected directly to the interface 5 of the SRX.
Setting the VLAN ID is simple, as every packet needs to be member of that VLAN.
ge-0/0/5 {
vlan-tagging;
unit 0 {
description orange;
vlan-id 832;
family inet {
dhcp;
filter {
output OrangePrio;
}
}
}
}
I've add an output filter :
firewall {
family inet {
filter OrangePrio {
term prio {
from {
protocol udp;
destination-port 67;
}
then {
syslog;
loss-priority low;
forwarding-class network-control;
accept;
}
}
term default_accept {
then accept;
}
}
}
}
I know this rule should change COS in IP Stack and not in 802.1q, but even, this one does nothing. The rule is hitted everytime the dhcp client make a request but it seems it does not change the COS.
I can't find any documentation to do this on the 802.1q header neither. Any help is appreciated !
Regards,
