Hello,
I'm a newbie at docsis.
I'm trying to provision a AVM FritzBox 6360.
This is my dhcp-config on the server:
subnet 10.201.1.0 netmask 255.255.255.0 {
range 10.201.1.100 10.201.1.253;
option subnet-mask 255.255.255.0;
option routers 10.201.1.254;
next-server xxx.xxx.xxx.xxx;
filename "config/default.bin";
option time-servers 10.201.1.254;
option time-offset 3600;
option dhcp-server-identifier docsis-mngmnt.domain.xxx;
option docsis-mta.dhcp-server-1 xxx.xxx.xxx.yyy;
}
host 24_65_11_dd_e8_5d {
hardware ethernet 24:65:11:dd:e8:5d;
fixed-address 10.201.1.66;
filename "config/100M.bin";
}
The cable modem get online with this config. But in the log-file is a repeating error:
29.10.14 07:20:45 DHCP RENEW WARNING - Field invalid in response v4 option
What is the reason for this error?
Best Regards
Paul
default-lease-time 3600;
max-lease-time 3600;
Same issue, with another repeating intervall.
What the error means is that the modem requested specific options using option 55 in its request and one or more of those options were not present in the response the dhcp server gave.
Use a packet capture (wireshark is a good one) to determine what options the modem is requesting and then update your subnet or host stanza in your dhcp server accordingly. Here is a list of dhcp options by number http://www.networksorcery.com/enp/protocol/bootp/options.htm
