Verifying Signaling
The ATM signaling protocol allows end-stations to establish, maintain,
and clear ATM connections between end points with virtual connections
(VCCs). Multiple virtual connections can exist on a physical link. There are
two types of virtual connections: a virtual path and a virtual channel.
You can verify that signaling is operational by viewing the virtual
connections — virtual path identifiers (VPIs) and virtual channel identifiers
(VCIs) that the system has established.
To verify that signaling is operational, from the top level of the
Administration Console, enter atm ports vcc list
Sample VCC list:
In addition to newly defined VCCs, two additional VCCs are listed, which
are reserved VPIs and VCIs used for signaling (VPI 0/VCI 5) and for the
UME ILMI (VPI 0/VCI 16).
