    Juniper OS version:14.1X53-D35.3.
    The specification Doc says QFX5100 supports 128 LAGs, maximum 8 ports per lag.
    the following is my configration:
    set groups CCAP_CFG interfaces ae0 aggregated-ether-options minimum-links 1
    set groups CCAP_CFG interfaces ae0 aggregated-ether-options link-speed 10g
    set groups CCAP_CFG interfaces ae0 aggregated-ether-options lacp active
    set groups CCAP_CFG interfaces xe-0/0/0 ether-options 802.3ad ae0
    set groups CCAP_CFG interfaces xe-0/0/1 ether-options 802.3ad ae0
    set groups CCAP_CFG interfaces xe-0/0/2 ether-options 802.3ad ae0
    set groups CCAP_CFG interfaces xe-0/0/3 ether-options 802.3ad ae0
    set groups CCAP_CFG interfaces ae0 mtu 2000
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching interface-mode trunk
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_INTERNAL_MGMT
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_SLOT_15
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_SLOT_15_VPN
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_VIDEO_VLAN
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_DOCSIS_MCAST_VLAN
    set groups CCAP_CFG interfaces ae0 unit 0 family ethernet-switching vlan members CCAP_RIP_CTRL_VLAN

    There is no problem for ae0 , LACP works perfect.
    The problem is on the following configuration: 
    Seems like name ae17 is strange for QFX.

    set groups CCAP_CFG interfaces ae17 aggregated-ether-options lacp active
    set groups CCAP_CFG interfaces ae17 aggregated-ether-options lacp periodic fast
    set groups CCAP_CFG interfaces ae17 mtu 2000

    set groups CCAP_CFG interfaces ae17 aggregated-ether-options link-speed 10g
    set groups CCAP_CFG interfaces ae17 aggregated-ether-options minimum-links 1
    set groups CCAP_CFG interfaces xe-0/0/8 ether-options 802.3ad ae17
    set groups CCAP_CFG interfaces xe-0/0/9 ether-options 802.3ad ae17
    set groups CCAP_CFG interfaces xe-0/0/10 ether-options 802.3ad ae17
    set groups CCAP_CFG interfaces xe-0/0/11 ether-options 802.3ad ae17
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching interface-mode trunk
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_INTERNAL_MGMT
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_SLOT_17
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_SLOT_17_VPN
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_VIDEO_VLAN
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_DOCSIS_MCAST_VLAN
    set groups CCAP_CFG interfaces ae17 unit 0 family ethernet-switching vlan members CCAP_RIP_CTRL_VLAN

    Commands are executed and committed perfectly.
    But when I want to show the interface ae17, or show lacp interface ae17, it prompts no device found.
    show lacp interfaces ae17
    error: device ae17 not found
    show interfaces ae17
    error: device ae17 not found

    The commands only show the interfaces ae0~9. and lacp is not working on ae17.

    Do I mis-configured something?

    Hi,

     

    Can you check the device count configured under chassis?

     

    QFX# show chassis aggregated-devices ethernet device-count

    I didn't configure this. Do I have to?

    Thanks, you are right, once I configure the device counter to 100, it can show the interfaces ae0~99.

    Thanks much.
