19.5.3 Option 82 Sub-option 2 Set Command

ras> acl dhcprelay82 suboption2 set <vid> <info>
where
This command adds the specified information for the relay agent (Option 82, Sub-option 2) for the
specified VLAN.
19.6 acl dhcpsnoop Commands
Use these commands to configure or show DHCP snooping settings on the subscriber ports. The
switch gets the client MAC-IP address information (in the reply from a DHCP server) and stores it in
the DHCP snooping table. The system only forwards packets from the clients whose MAC-IP address
is in the DHCP snooping table. Packets from unknown IP address(es) are not forwarded (dropped).
This feature prevents subscribers from assigning their own static IP addresses. LAN 2 LAN allows
you to set whether or not a DHCP server connected to a subscriber port is permitted to receive and
send traffic through the IES.
