Dhclient not sending option 60



  • I have setup vlan 4 on my WAN interface em0, because I need that for IPTV to work. I'm also sending an extra option: 'dhcp-client-identifier "IPTV_RG"' . However, a tcpdump from em0_vlan4, doesnt show the option being sent:

    
    18:33:58.244426 IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328)
        0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:0c:29:d4:64:2b (oui Unknown), length 300, xid 0xf21823d6, secs 41, Flags [none]
              Client-Ethernet-Address 00:0c:29:d4:64:2b (oui Unknown)
              Vendor-rfc1048 Extensions
                Magic Cookie 0x63825363
                DHCP-Message Option 53, length 1: Discover
                Client-ID Option 61, length 7: hardware-type 73, 50:54:56:5f:52:47
                Hostname Option 12, length 4: "fw01"
                Parameter-Request Option 55, length 9:
                  Subnet-Mask, BR, Time-Zone, Classless-Static-Route
                  Default-Gateway, Domain-Name, Domain-Name-Server, Hostname
                  Option 119
    
    

    Why does dhclient not send option-60 with the request?

    Solved. Needed to specify dhcp-class-identifier instead of dhcp-client-identifier.
