LECS Configuration Direct VCC (Read-Only)
Displays the VPI and VCI of the Configuration Direct Virtual Channel Connection (VCC) that the
LEC has with the LECS. This connection is used to obtain LAN Emulation configuration
parameters, and is also used by the LEC to learn the address of the LES.
LES Control Direct VCC (Read-Only)
Displays the VPI and VCI of the Control Direct Virtual Channel Connection (VCC) that the LEC
has with the LES. This connection is used by the LES and the LEC to distribute control traffic to
all LECs. If this LEC is participating in an ELAN, this connection is mandatory.
LES Control Distribute VCC (Read-Only)
Displays the VPI and VCI of the Control Distribute Virtual Channel Connection (VCC) that the
LEC has with the LES. This optional connection is used by the LES to distribute control traffic to
all LECs.
BUS Default Multicast Send VCC (Read-Only)
Displays the VPI and VCI of the Multicast Send Virtual Channel Connection (VCC) that the LEC
has with the BUS. This connection is used by the LEC and the BUS to send all broadcast
transmissions for address resolution. This connection is also used for unicast and multicast
transmissions, when the destination address is unknown. If this LEC is participating in an ELAN,
this connection is mandatory.
BUS Default Multicast Forward VCC (Read-Only)
Displays the VPI and VCI of the Multicast Forward Virtual Channel Connection (VCC) that the
LEC has with the BUS. This connection is used by the LEC to receive data from the BUS about
address resolution. If this LEC is participating in an ELAN, this connection is mandatory.
3.14.1 Viewing Multiple ELANs
To view additional ELANs, perform the following steps:
1. Use the arrow keys to highlight the LEC Index field.
2. Press the SPACE bar to step through all of the LECs currently configured on the
VHSIM2-A6DP. The user may also enter the numerical LEC index to have the applicable
ELAN’s properties display immediately.
NOTE: In many ELAN implementations, the LECS Configuration Direct VCC is only
used temporarily, and the VCC may time out.
