  • 1.  EX3400 limit DSCP traffic

    Hi Experts,

    I see that the firewall filter has a DSCP option when setting throttling.
    So I tried to use, but found that it couldn't be triggered.
    Is this option not applicable to throttling?

    set interfaces xe-0/0/0 unit 0 family ethernet-switching interface-mode trunk
    set interfaces xe-0/0/0 unit 0 family ethernet-switching vlan members test
    set interfaces xe-0/0/1 unit 0 family ethernet-switching vlan members test
    set interfaces xe-0/0/1 unit 0 family ethernet-switching filter input limitPak
    set interfaces xe-0/0/1 unit 0 family ethernet-switching filter output limitPak
    
    set firewall family ethernet-switching filter limitPak term 0 from dscp cs0
    set firewall family ethernet-switching filter limitPak term 0 then three-color-policer single-rate qoslimit
    set firewall family ethernet-switching filter limitPak term 1 then accept
    
    set firewall three-color-policer qoslimit single-rate committed-information-rate 32k
    set firewall three-color-policer qoslimit single-rate committed-burst-size 1500
    set firewall three-color-policer qoslimit single-rate excess-burst-size 1500
    
    set vlans test vlan-id 10

    Hi Gary:

    I believe you are using the incorrect interfaces. On all EX3400 I have the 10Gb (xe) interfaces count from xe-0/2/0 to xe-0/2/3. The PIC for the 48 1Gb ports is 0, as in ge-0/0/0. The 40Gb interfaces at the rear of the EX3400 are on PIC 1, as in et-0/1/0 to et-0/1/1. The 10Gb interfaces are on PIC 2, as in xe-0/2/0 to xe-0/2/3.

    With incorrect interfaces your firewall will likely do nothing as those interfaces don't exist.

    Hi Footy-Smurf,

    Thanks for your reply.

    I pre-config it from EVE-NG first and test it off work.

    I discussed this with jtac, and it seems we need to do it with firewall filters, which will be long to write and take time to set up and tweak.
    I think there is a need for a convenient way to manage DSCP current traffic limit and guaranteed bandwidth.
