bootpd Client specified unacceptable option length

[Eric Jacklin]

Server Model : Rp7420
OS : Hp UX 11.11
Error :bootpd[3426]: Option 43: Client specified unacceptable option length

Would you please provide me any solution so that i can fix this bootpd messages in syslog

Hi

This error is caused when a DHCP client sends a request using option 43 where the option 43 value exceeds 80 bytes. This is unlikely to be a transient behaviour on the part of a DHCP client, so it seems unlikely that it is the cause of the failure to obtain DHCP addresses which occurred on two
occasions. It is more likely that the error report in syslog is coincidental.

This issue is been fixed by the patch PHNE_36217 - 11.11 bootpd(1M)/DHCP, tftp(1) and tftpd(1M) patch

Thanks & Regards
