2Forward Unicast Packets Only:

If a protocol is configured for routing, and a packet for that protocol type is received from the LAN that is not addressed to the MAC address of the OCR 812, it is bridged. Additionally, ARP broadcasts for IP addresses other than that of the OCR 812 are also bridged. Other broadcasts for the configured protocol are not bridged. To configure the Bridge Firewall for this mode, use the command:

set bridge firewall fwd_unicast_only

3Forward Broadcast/Unicast Packets:

Unicast packets for a configured protocol received from the LAN that are not addressed to the MAC address of the OCR 812 are bridged. Received broadcasts (e.g., DHCP) are bridged. To configure the Bridge Firewall for this mode, use the command:

set bridge firewall fwd_bc_and_unicast

Packets received from the WAN do not pass through the Bridge Firewall. Instead, packets received from the WAN are delivered to the router or bridging function based on their encapsulation and on the state of the MAC-Encapsulated Routing parameter in the remote site profile.

In general, a packet received in a routed encapsulation (i.e., IPCP or Routed RFC 1483) is delivered to the router. A packet received in a bridged encapsulation is passed on to the bridge. If MAC-Encapsulated Routing is enabled, the received (bridge-encapsulated) packets are delivered to the router.

System	This section provides details and examples for performing the following system
Administration	administration tasks:
	Setting Date and Time
	Setting System Identification
	Configuring Web Browser and TELNET Login Access
	Providing TFTP Access
	￿Setting Password Protection
	Remember to save your configuration using the save all command before
	rebooting your OCR 812 so that your changes will be written to permanent FLASH
	memory.
Setting Date and Time	Date and time values are automatically set when the OCR 812 powers-up.
	Optionally, CLI commands can be used to manually set these values.
	To manually set the date, use the command set date (which sets the system date,
	and leaves the time unchanged).

Set date command format is dd-mmm-yyyy.

￿Month (mmm) must be specified as the first three characters of the month name.
