The output from the elstat -n net_interface -v command shows the
following:
• The name of the primary and secondary ELANs, and their ATM and
MAC addresses.
• The Local Segment ID for Token Ring ELANs.
• The ATM address of the primary and secondary LECS, LES, and
BUS. This allows you to see if there is anything unusual about any of
the ATM addresses, and at which stage the joining procedure breaks
down. For example, if the LES ATM address and VCC fields are OK,
and the BUS ATM address is OK but its VCC fields are empty, this
tells you that although the LES is able to identify the BUS, it is
unable to set up a connection to it. For details about the ELAN
joining stages, see “How an Emulated LAN Works” on page 42.
• The VPI and VCI numbers of each connection (in the VCC field). If a
value is returned as -.-, this means that the VPI/VCI could not be
set up.
• The current status of the ELAN. If the LEC has successfully joined
the ELAN, the status is shown as “Operational”. If the status is not
operational, this can be because the LECS or LES did not reply, for
example.
