Note
There is a well-known restriction that the IP interfaces of the IBM
8285 and the IBM 8260 should not use IP network number 10 because
it is use d on their internal network. This restriction applies not only
to the CIP interface of the IBM 8285 but also to that of the LECs. It is
planned to remove this restriction when the control point code
supports PNNI phase 1, expected in 1997.
− Subnet Mask
The mask used to allocate the IP address bits. Must match the mask
used by the default gateway.
− Default Gateway
Specify the address to forward packets to to reach other IP networks
when communicating with an IP device beyond the IP network. In the
LANE network, the default gateway should be an IP router on the same
ELAN of the IP device or on a legacy LAN via a LANE bridge on the same
ELAN.
− Individual MAC Address
Specify the individual MAC address of the LEC. The address format
should be canonical for Ethernet ELAN and non-canonical for token-ring
ELAN and both universal and local administered address (UAA/LAA) are
supported. It should be unique throughout the transparent bridging
network and in a source routing bridging segment just like the MAC
address on a legacy LAN.
− Associated LES or LECS ATM address
Specify the ATM address of the LES with which to register or the LECS
which knows the ATM address of a designated LES. The LES will be
used for resolving ELAN MAC addresses in to ATM addresses.
To get the designated LES ATM address, the following options are
offered:
- Use a pre-defined LES ATM Address
If you don′t have the LECS on the ELAN, you have to specify the LES
ATM address in each LEC definition.
When the 8285 LEC is attached to this type of ELAN, the SET DEVICE
LAN_EMULATION_CLIENT command with the parameter
NO_LECS_WITH_LES followed by the LES ATM address is used to
pre-define the LES ATM address.
- Use a pre-defined LECS ATM address
If you have the LECS on the ELAN but don′t want to use dynamic
address resolution, you can specify the LECS ATM address on each
LEC definition.
When the 8285 LEC is attached to this type of ELAN, the SET DEVICE
LAN_EMULATION_CLIENT command with the parameter
NO_LES_WITH_LECS followed by the LECS ATM address is used to
pre-define the LECS ATM address.
- Use a dynamic LECS ATM address
