Enumeration
When the dhcp_snoop function is enabled, all address_binding
disabled ports will act as DHCP server ports (the switch will
learn IP addresses through DHCP server ports (by DHCP OFFER
and DHCP ACK packets)).
The auto-learned IP-MAC binding entry will be mapped to a specific
source port based on the MAC address learning function. This entry
will be created as an ACL-mode binding entry for this specific port.
Each entry is associated with a lease time. When the lease time
expires, the expired entry will be removed from this port. The
automatically learned binding entry can be moved from one port to
another port if the DHCP snooping function has learned that the MAC
address has moved to a different port.
Consider a case where DHCP snooping learns a binding entry, and the
same IP-MAC binding entry has been statically configured. Suppose
that the learned information is consistent with the statically
configured entry, then the automatically learned entry will not be
created. Suppose the entry is statically configured in ARP
mode, since the automatically learned entry will be created in ACL
mode, the entry will become ACL mode. Suppose the entry is
statically configured on one port and the entry is automatically
learned on another port, then both entries will exist.
When the dhcp_snoop function is disabled, all of the automatically
learned binding entries will be removed.
