My ISP (M1 in Singapore) provides a dynamic IP via DHCP and requires the usage of VLAN 1103 for the uplink connection together with the forced priority setting of "1".
In Cisco IOS I could easily do it using something like:
! policy-map NGNBN class class-default set cos 1 !
and then assigning it to a virtual interface with:
! interface GigabitEthernet0/0.1103 description M1 encapsulation dot1Q 1103 ip address dhcp ip virtual-reassembly in no cdp enable service-policy output NGNBN !
How would I do the same for a Juniper J2320 router?
I've tried the usual vlan-id: 1103; and followed the example at http://forums.juniper.net/t5/SRX-Services-Gateway/How-to-set-802-1p-Cos/m-p/111092#M13972 but it doesn't seem to work at all.
