  • 1.  6300m Access port native vlan not passing DHCP

    Posted Feb 16, 2021 10:13 AM

    Not sure if my title is accurate, but anyway I have wireless access points that connect to a switch and the old procurve config was like

    int 1
    untagged 164

    tagged 165-174

    Now I programmed up a new 6300m switch and thought this was the new way of trunking a port
    int 1/1/1
    vlan trunk native 164
    vlan trunk allowed 165-174

    so when i plug an AP in it doesn't get a DHCP address , if i make the port "vlan access 164" it gets an address from DHCP.
    I thought maybe I had to add 164 to the trunk allowed and I even did "vlan trunk allowed all" but still no dice =(

    Can ping the default gateway for the vlan and DHCP server and the wireless master controller when i assign an address to the vlan interface on the 6300m.

    Hi,

    You need to add vlan 164 to trunk allowed and it will be work

    I tried that as per my original post sorry, still no DHCP.
    Here is my config now that i have access to the switch.

    !
    interface lag 100
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed 1,10,20,160-175,1150,1734-1736
    lacp mode active
    !
    interface 1/1/17
    no shutdown
    description WIFI-AP
    no routing
    vlan trunk native 164
    vlan trunk allowed 162,164-172,174-175
    !
    interface 1/1/51
    no shutdown
    description SC1
    lag 100
    !
    interface 1/1/52
    no shutdown
    description SC2
    lag 100
    !!
    If I make the port "vlan access 164" I can get an address.
    On my core switch the config looks like this
    !
    interface lag 30 multi-chassis
    vsx-sync vlans
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed 1,20,161-175,1150,1734-1736
    lacp mode active
    !
    interface 1/1/30
    no shutdown
    lag 30
    !
    interface vlan 164
    ip address 10.128.164.253/24
    ip helper-address 10.128.160.50
    ip helper-address 10.128.160.51
    ip helper-address 10.128.160.176
    vrrp 164 address-family ipv4
    address 10.128.164.254 primary
    preempt delay minimum 5
    priority 105
    no shutdown
    track 1
    exit

    so after rebooting the switch it works, but also my fluke network tester was giving me some errors.  It was behaving differently than an AP or laptop.
    what a dud.
