Managing the Address Forwarding Table
Option 82 for DHCP
Option 82 for DHCP includes two suboptions:
■
Suboption 1 identifies the slot and physical port number from
which the DHCP request was received.
■
Suboption 2 identifies the IP address and, if available, the
system name of the switch.
By default, both of these suboptions are enabled. You can change
the status of either or both suboptions by using the Web Agent,
Command Line Interface (CLI), or SNMP.
