dhcp-server on 8320

    Hello,

    I am working on setting up a few DHCP-Server Pools on a VSX Cluster. I followed this thread; DHCP at Switch 8320 | Wired Intelligent Edge (arubanetworks.com), but the issue I am having is that I have DHCP-Server setup, the state and mode when I do show dhcp-server say operational and true, but I am not getting an IP Address.

    This is how I had it before, and I was still having the same issues:

    Configure Pool:
    dhcp-server vrf default
    pool DHCP_Test
    range 10.1.1.1 10.1.1.154 prefix-len 24
    dns-server 10.15.5.5
    default-router 10.1.1.2
    domain-name example.com
    lease 00:10:00
    exit
    authoritative
    enable

    Connect the Pool and VLAN:
    interface vlan 2
    vsx-sync active-gateways
    description Test_DHCP
    ip mtu 9100
    ip address 10.1.1.2/24
    active-gateway ip mac 12:01:00:10:11:04
    active-gateway ip 10.1.1.1

    Assign interface to VLAN:
    interface
    no routing
    no shutdown
    vlan access 2

    I feel like there is something I am missing, but I am not sure what...

    Have you synchronized dhcp servers settings over the VSX with: vsx-sync dhcp-server (in vsx context)?

    I did not have that in the vsx settings. It all seems to be working now.

    I do have a question with the dhcp-server configuration; I have a bunch of pools I set up. I wanted to make sure each was giving out and IP and setup one interface with each pool/ vlan. I was going a little fast, but I noticed after a few, I stopped geting IP addresses. Is that normal, I was thinking that maybe it is something with a security feature.
