Ethernet
Encapsulation Type
As mentioned previously, the Ethernet port on the front panel of the ATM
Switch Fabric Module is provided for the management of the CoreBuilder
9000 ATM Enterprise Switch either by the LMA via Telnet or by
out-of-band SNMP.
The Ethernet frames that the managing device transmits to the
CoreBuilder 9000 ATM Enterprise Switch Ethernet port can be either of
two types, depending on how the Ethernet data is encapsulated in the
Ethernet frame. These are referred to as
Ethernet encapsulation types :
Standard encapsulation - according to 802.3
Enhanced encapsulation - LLC
Configure the CoreBuilder 9000 ATM Enterprise Switch to accept the
encapsulation type being sent to it by the managing device. The system
management setup menu allows you to perform this setup. For more
information, see “Update Ethernet Encapsulation Type” on page 79.
