Topology Table tab fields


Field Description
Slot
The slot on which the topology message was received.
Port
The port on which the topology message was received.
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. This 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 auto topology use the SrcIndx of the segment as the segment identifier; switches use a computed value equal to (256 * s) + p.
In this context, the letter "s" is the board, card, or slot number and the letter "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
The chassis type of the device that sent the topology message.
BkplType
The backplane type of the device that sent the topology message.
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--topology information has recently changed.
  • heartbeat--topology information unchanged.
  • new--sending agent is in new state.
