Figure 6- 15. DHCP/BOOTP Relay Interface Settings and DHCP/BOOTP Relay Interface Table window
The following parameters may be configured or viewed.
Parameter Description
Interface
The IP interface on the Switch that will be connected directly to the Server.
Server IP
Enter the IP address of the DHCP/BOOTP server. Up to four server IPs can be configured
per IP Interface
DHCP Auto Configuration Settings
The DHCP autoconfiguration function on the Switch will load a previously saved configuration file for current use.
When DHCP autoconfiguration is Enabled on the Switch, the DHCP reply will contain a configuration file and path
name. It will then request the file from the TFTP server specified in the reply.
Figure 6- 16. DHCP Auto Configuration Settings window
When DHCP autoconfiguration is Enabled, the Switch becomes a DHCP client automatically after rebooting. The
DHCP server must have the TFTP server IP address and configuration file name, and be configured to deliver this
information in the data field of the DHCP reply packet. The TFTP server must be running and have the requested
configuration file in its base directory when the request is received from the Switch. Consult the DHCP server and
TFTP server software instructions for information on loading a configuration file.
If the Switch is unable to complete the autoconfiguration process the previously saved local configuration file present
in Switch memory will be loaded.
MAC Address Aging Time
This table specifies the length of time a learned MAC Address will remain in the forwarding table without being
accessed (that is, how long a learned MAC Address is allowed to remain idle). To change this, type in a value
representing the MAC address age-out time in seconds. The MAC Address Aging Time can be set to any value
between 10 and 1,000,000 seconds. The default setting is 300 seconds.
To access this table, click Configuration > MAC Address Aging Time:
