  • 1.  ArubaOS-CX 8325 DHCP Relay question

    Posted Mar 04, 2021 05:08 AM
    Hi all,

    I have a DHCP server together with my AD in a VM.
    On my Switch I had configure each VLAN with IP-helper-address to the DHCP Server.
    interface vlan 300
    ip helper-address 10.100.110.7
    ip helper-address 10.100.110.6

    My DHCP Valid request is 2288110 but Valid Responses is only 66, is this normal ?
    Thank you

    Please check if the COPP policy is dropping some requests (in case of intensive stress test for instance):

    8325-1# show copp-policy default
    class drop priority rate pps burst pkts hardware rate pps
    --------------------- ---- -------- -------- ---------- -----------------
    dhcp-ipv4 1 1000 1000 1000
    dhcp-ipv6 1 1000 1000 1000

    8325-1# show copp-policy statistics class dhcp-ipv4
    Statistics for CoPP policy 'default':
    Class: dhcp-ipv4
    Description: Dynamic Host Configuration Protocol IPv4.
    priority : 1
    rate (pps) : 1000
    burst size (pkts) : 1000

    bytes passed : 0 bytes dropped : 0
    packets passed : 0 packets dropped : 0
    avg_packet_size_passed: 0 avg_packet_size_dropped: 0
