ios dhcp server - insufficient space for option 161

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
