Replacing a LAN Emulation LEC Adapter

Changing the adapter’s hardware MAC address has no effect on the LAN

Emulation conﬁguration. So, you do not need to perform any

reconﬁguration if you replace an ATM adapter on which ELAN

interfaces are conﬁgured. The MAC address is not updated dynamically

in the conﬁguration ﬁles for each ELAN interface, so the previous MAC

address continues to be used.

Note that if you set the ELAN MAC address parameter to “Default”

(meaning that the ATM adapter’s own hardware MAC address is used on

the ELAN), and later change the ATM adapter, then in SAM the ELAN

MAC address is automatically set to “Manual” and the previous

hardware MAC address remains displayed. If you reconﬁgure the ELAN

MAC address parameter to “Default”, then the new adapter’s hardware

MAC address is used instead.
