ATM Address Shows the ATM address of LEC for
either the ATM Module or the ATM Switch.
If Near is shown in the End field, the address is the
address of the LEC in the ATM Module.
If Far is shown in the End field, it is the address of the
LEC in the ATM Switch or attached ATM device at the
far end of the connection.
Type

types can be:
Incoming — the switched virtual circuit was set up by
the Far End LEC.
Outgoing — the switched virtual circuit was set up by
the Near End LEC.
Reserved — a permanent virtual circuit has been set up.

Setting Up Resilient Links
You can protect a critical communication link against
failure by ensuring that, should the main communication
link fail, a standby duplicate communication link
immediately and automatically takes over the task of
the main link.
Each main and standby link pair is referred to as a
resilient link pair .
■
If you wish to setup an ATM port as part of a
resilient link, the other port in the resilient link
must be a
Virtual LAN Trunk (a member of all
VLANs).
■
Typically the ATM Module port is paired with a Fast
Ethernet port on the ATM Switch.
