The value of sysUpTime at the time this VC entered its current operational
state.
MgmtMode
It denotes the Management Mode of the ATM VC. If it is Data, then only
data transmission can take place. If it is Mgmt, then management of
remote CPE device can happen on that ATM VC and packets on that ATM
VC shall start coming to Control Plane. In DataAndMgmt mode, data
transmission as well as remote CPE management can happen on the
same ATM VC interface. In DataAndMgmt mode, the only acceptable
value for atmVCCAAL5EncapType is llc. In Mgmt mode, EoA interface
can't be created on the ATM VC and both Ethernet as well as non-Ethernet
packets on that ATM VC shall be received at Control Plane. In
DataAndMgmt mode, if EoA is created then only non-Ethernet packets on
that ATM VC shall be received at Control Plane. However, if EoA is not
created then all the packets on that ATM VC shall be received at Control
Plane. However, to configure ATM VC in DataAndMgmt mode, good
practice is to create ATM VC in disable mode till EoA is created on it, to
prevent flooding at Control Plane. In order to run STP, the mode has to be
DataAndMgmt. If the mode is RawATM(4), ATM cells are given to
Control Plane. In this mode, EoA interface cannot be created on the ATM
VC. If EoA interface is already created on the ATM VC, its mode cannot be
changed to either Mgmt(2) or RawATM(4). This field is not valid if
encaptype is Ethernet.
RowStatus
This defines the row-status of the interface entry
VC Type
This field specifies whether VC type is PVC or SVC.
VC Topology
This field specifies the VC connection topology type.
Max simultaneous
protocol
This field specifies the maximum number of simultaneous active protocol
stacks supported on this interface. Currently, only one protocol stack is
supported.
Auto Status
This field specifies whether the Auto mode is to be enabled or not. In the
Auto mode, the stack above this interface will be determined and created
based on the protocol packets sensed on this interface. For example, if the
protocol packet sensed above this interface is an EoA packet, then the
corresponding EoA stack will be created above this interface. However,
the corresponding EoA interface must have been created with the
gsvEoaConfigMode field's bit corresponding to the 'Auto' set.
Auto Supported
Protocol
This field specifies Higher layer protocols which are supported for auto
detection on the given ATM VC. Only the packets if the protocols
mentioned in this field can lead to Auto detection. This field is meaningful
only when autostatus flag is enable.
Auto VC Mux Forced
This field specifies if the encap type detected is VCMux, the user can
