Configuring an Emulated LAN
3.4.1.5 LECS Control Parameters
Specifying values for keys in the
LECS
group provides control over the opera-
tion of the LECS process.
NOTE:
If you change the values of the LECS control
parameters while the LECS process is
running, the new values do not take effect
until the LECS process is stopped, and then
restarted.
When a client contacts the LECS, the connections established are known as
Configuration Direct VCCs. To override the default value of the
VCC_TimeOut_Period
key (the number of seconds before an idle Configura-
tion Direct VCC is automatically closed by the LECS), enter a statement simi-
lar to the following:
LECS.VCC_TimeOut_Period: 1200
The LECS periodically checks whether its configuration file has been modi-
fied, and, if it has, the file is reread. The length of this period, in seconds, is
given by the
Reload_Period
key:
LECS.Reload_Period: 600
The
Permanent_Circuits
key holds a comma-separated list of
VPI.VCI
pairs
denoting the local ends of 0.17 PVCs on which the LECS should listen. For
example:
LECS.Permanent_Circuits: 0.42, 0.112
The LECS can provide the client with a fourteen-bit pattern to permute the
MAC-address generation algorithm. This bit pattern is specified with the
MAC_Address_Base
key.
LECS.MAC_Address_Base: 38fe
