Use routing
Devices on one Emulated LAN can only communicate with devices on another Emulated LAN using routing protocols. Routing is outside the scope of this user guide. Consult the user guide that accompanies your router.
Is the MAC Address in the Switch Database?
If the MAC Address of a device connected to an Ethernet port on the Switch is not entered in the Switch Database, none of the LECs on the Switch can act as a proxy for that device. All LE_ARP requests will fail to locate the MAC address, and the requesting LEC will not be able to map an ATM address to that MAC address.
If a LEC fails to map an ATM address to a MAC address, locate the device with that MAC address.
Is the MAC address in the Switch Database of the Switch connected to the device with that MAC address?
Yes — Go to step 5.
No — Go to step 4.
Enter the MAC Address in the Switch Database
There are several reasons why the MAC address is not in the Switch Database:
■The Switch Database is full.
■The entry may have
■There may have been a problem with the physical connection between the device and the Ethernet port on the Switch.
Identify the problem, and ensure that the MAC address is added to the Switch Database.
Is There Still a Problem?
Yes — Contact Technical Support. Refer to Appendix E. No — No further action is required.
