| Description | Each entry contains information about one wavelength
bundle to one remote switch. The wavelength bundle is
modeled as a single logical link (identified by
coscpBundleIfIndex) with a single control and management
channel. This logical link is known as the Optical
Supervisory Channel (OSC). At any one time, only one
wavelength in the bundle is selected to transmit the OSC
control and network management traffic. This link is
identified by coscpBundleActivePortId.
The wavelength bundle must be created by a manager
using the coscpBundleRowStatus object. Once the row has
been activated, an interface index is assigned by the
agent and shown in coscpBundleIfIndex. This value can then
be used by the manager to configure control and management
protocols, e.g. to configure the OSC's IP address.
Aside from coscpBundleRowStatus, the other objects in the
row are read-only, since they reflect the dynamic state of
the wavelength bundle as determined by OSCP.
The wavelength bundle does not become operational until at
least one component link reaches the hello state 'twoWay',
i.e., until at least one entry in coscpLinkTable with
coscpLinkRemoteSwitchId value equal to the value of
coscpBundleRemoteSwitchId and coscpLinkDerivedBundleId
value equal to the value of coscpBundleId has
coscpLinkHelloState value 'twoWay'. The operational status
of the wavelength bundle is indicated by the value of
ifOperStatus in the ifEntry with ifIndex value equal to
the value of coscpBundleIfIndex. |
