Hi,
I am having issues with a simple dhcp server configuration where the client sometimes does not receive the location of tftp server (option 161).
Below is the related dhcp debug snippet:
Jun 19 19:13:53.165: DHCPD: client's VPN is .
Jun 19 19:13:53.165: DHCPD: No option 125
Jun 19 19:13:53.165: DHCPD: BOOTREQUEST received from BOOTP client x.x.x.x on interface FastEthernet0/0.
Jun 19 19:13:53.165: DHCPD: Sending BOOTREPLY to BOOTP client x.x.x.x (y.y.y.y).
Jun 19 19:13:53.165: DHCPD: insufficient space for option 161.
Jun 19 19:13:53.165: DHCPD: no option 125
Jun 19 19:13:53.165: DHCPD: broadcasting BOOTREPLY to client x.x.x.x.
Jun 19 19:13:53.165: DHCPD: client's VPN is .
Jun 19 19:13:53.165: DHCPD: No option 125
Jun 19 19:13:53.165: DHCPD: DHCPDISCOVER received from client x.x.x.x on interface FastEthernet0/0.
Jun 19 19:13:53.165: DHCPD: Sending DHCPOFFER to client x.x.x.x (y.y.y.y).
Jun 19 19:13:53.165: DHCPD: no option 125
Jun 19 19:13:53.165: DHCPD: broadcasting BOOTREPLY to clientx.x.x.xd.ip dhcp pool WYSE
What does 'insufficient space for option 161' mean as well as 'no option 125' in this context?
Thanks

option 125 is "Vendor option". is this happenes with only ONE specific client?

happens to some clients, at time of failure DHCP debug returns 'insufficient space for option 161' which I can not find any explanation for
