Disabling DHCP Snooping
If you disable DHCP snooping on the whole switch ( no service dhcp-snooping command
on page 56.24 ), all the DHCP snooping configuration is removed, except for the Access
Control Lists (ACL). Any ACLs on a port that permit traffic matching DHCP snooping entries
and block other traffic, will block all traffic if DHCP snooping is disabled on the port. If you
disable DHCP snooping either on the whole switch or on particular VLANs (
no ip dhcp
snooping command on page 56.9 ), you must also remove any DHCP snooping ACLs from
the ports to maintain connectivity ( no access-group command on page 34.4 ).
