System Administration 6-392 Forward Unicast Packets Only:If a protocol is configured for routing, and a packet for that protocol type isreceived 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 theOCR 812 are also bridged. Other broadcasts for the configured protocol are notbridged. To configure the Bridge Firewall for this mode, use the command:set bridge firewall fwd_unicast_only3 Forward Broadcast/Unicast Packets:Unicast packets for a configured protocol received from the LAN that are notaddressed 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 thecommand:set bridge firewall fwd_bc_and_unicastPackets received from the WAN do not pass through the Bridge Firewall. Instead,packets received from the WAN are delivered to the router or bridging functionbased on their encapsulation and on the state of the MAC-Encapsulated Routingparameter in the remote site profile.In general, a packet received in a routed encapsulation (i.e., IPCP or Routed RFC1483) is delivered to the router. A packet received in a bridged encapsulation ispassed on to the bridge. If MAC-Encapsulated Routing is enabled, the received(bridge-encapsulated) packets are delivered to the router.SystemAdministration This section provides details and examples for performing the following systemadministration tasks: Setting Date and Time Setting System Identification Configuring Web Browser and TELNET Login Access Providing TFTP Access Setting Password ProtectionRemember to save your configuration using the save all command beforerebooting your OCR 812 so that your changes will be written to permanent FLASHmemory.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 monthname.
