Looks like page 280 to me :-)

Enable DHCP snooping on each switch and configure it to work on VLAN 1 (the default). Set the port at each site where the DHCP server is connected to 'trusted'.

Job done.

PDF page 311 is "Defining reserved MAC Addresses", so that's not right either! :-D

And the page numbers are on each page...

I checked it again. Uuuuups 311 (at my place) is wrong snooping - IGMP snooping - So, you are definitely right.
