SET BPORT_LEC FRAME
2-75
SET BPORT_LEC
FRAME
Use the SET BPORT_LEC FRAME command to specify two parameters for the
emulated LAN:
■
Maximum frame size
■
Maximum unknown frame count
BPORT is an abbreviation for Bridge Port.
LEC ports are logical ports, all of which overlay one physical ATM/Synchronous
Optical Network (SONET) port.
Format
Example
The following command sets the maximum frame size of the LEC in slot 4,
port 1 to 1516:
CB5000> set bport_lec 4.1 frame max_frame_size 1516
Bridge Port 04.01 parameter set.

slot.lec Identifies the slot and LEC for this operation.
slot (1 through 17) is the slot number and
lec is one of up to 64 LAN
Emulation Clients defined as logical ports for the ATM Backbone
SwitchModule. For example, to identify LEC 32 on the ATM Backbone
SwitchModule in slot 4, enter
4.32
max_frame_
size
Specifies the maximum frame size (in octets) for the emulated LAN.
option You can choose from one of the following options:
■
1516
■
4544
■
unspecified
Unspecified allows the LECs to determine the maximum frame size when
the LEC tries to join the emulated LAN.
You can create an FDDI-like LAN emulation by configuring the LAN type
as IEEE 802.3 and then setting the maximum frame size to 4544.
max_unkwn_
frame_count
Specifies the maximum number of frames sent by a LEC to the Broadcast
and Unknown Server (BUS) for a given unicast LAN destination within a
specified maximum unknown time period.
option You can choose from a range of 1 through 10 frames.
