**Edit Diagnostics Topology Table**
Item	Description
Slot	The slot on which the topology message was received. NOTE: There is an artificial 'row' for the reporting agent with slot and port equal to zero. NOTE: Non-modular devices that do not have multiple slots should set this value to 1.
Port	The port on which the topology message was received. NOTE: there is an artificial 'row' for the reporting agent with slot and port equal to zero.
IpAddr	The IP address of the sender of the topology message.
SegId	The 'segment identifier' of the segment from which the remote agent sent the topology message. The value is extracted from the received topology message. Different devices may use different methods for representing the segment identifier. For example, system 5000 NMMs that run multi-segment autotopology use the SrcIndx of the segment as the segment identifier; switches use a computed a value equal to '(256 * s) + p' where 's' is the board, card or slot number and 'p' is the port number on and as seen by the switch sending the topology message; system 3000 NMMs use the lower three bytes of the MAC address of the NMM as the segment identifier. In any case, the 'segment identifier' uniquely identifies the network segment in the remote device from which the topology message was sent.
MacAddr	The MAC address of the sender of the topology message.
ChassisType	?
BkplType	?
LocalSeg	Indicates if the sender of the topology message is on the same Ethernet segment (i.e., NOT across a bridge) as the reporting agent.
CurState	The current state of sender of the topology message. The values are: topChanged(1)...topology information has recently changed heartbeat(2)....topology information unchanged new(3)..........sending agent is in new state.
