Enable ALTERNATE ATM MAC address
– Set this characteristic to yes to enable the ATM media access control (MAC)
address you specify in the ALTERNATE ATM MAC address field.
v
ALTERNATE ATM MAC address
– Type the MAC address in hexadecimal format (for example:
0x0000D10008ED
).
Note: To facilitate an easy swap of ARP servers and/or server adapters, the
option of a user-specified alternate MAC address is provided. Because an
endpoint’s ATM address is partially derived from the adapter’s MAC
address, changing an adapter in an endpoint changes that station’s ATM
address.
If an ARP server adapter is changed, it is not necessary to change the ARP
server ATM address in each ARP client. The MAC address of the previous
configuration can be entered as the alternate MAC address of the new adapter.
Each MAC addresses within a network, however, must be unique.
v
ATM Adapter PDU Size
– ATM Adapter PDU (Protocol Data Unit) Size field specifies the maximum
packet size that the IP stack generates for the ATM interface.
– Do not change the default value of 9180 unless another PDU size has been
configured and is used by all other hosts and routers in the IP subnet.
To see the range of valid values for this setting press F4.
5. When the Command status in the Command Status screen changes from
running
to
OK
, press F3.
6. To exit SMITTY, press F10.
