  • 1.  Aruba cx 6000 dhcp problem

    Posted Jun 28, 2022 11:37 AM
    Hi,

    I would like your help. I have configure my new 6000 sw but my client doesn't get dhcp .
    I did know hoe to configure "ip-helper" in the old SW version but in CX things have changed.

    I have vlan 24 for domain pc that need to get dhcp.
    i can ping the gw for the sw mgmt but not the gate way for the dhcp.

    Thank you,

    Michel vaillancourt

    Hi Michel,

    I guess you are referring to the ip helper-address command on older ProCurve/Aruba AOS-S devices. 
    The command is still available in the in the DHCP relay settings.
    I'm linking the IP Services guide for 4100i/6000/6100 switch series:
    https://www.arubanetworks.com/techdocs/AOS-CX/10.10/PDF/ip_services_4100i-6000-6100.pdf
    The explanations from this topic start on page 61, but you can find a configuration example for what you are looking for on page 63:
    switch(config)# dhcp-relay
    switch(config)# interface 1/1/1
    switch(config-if)# vlan access 100
    switch(config-if)# exit
    switch(config)# interface vlan 100
    switch(config-if-vlan)# ip address 198.51.100.1/24
    switch(config-if-vlan)# ip helper-address 10.10.20.209
    switch(config-if)# exit
    switch(config)# dhcp-relay option 82 replace mac
    switch# show dhcp-relay
    ​
