C H A P T E R 7 Displaying SNMP Parameters
141
• The backplane type of the sender, for the 7190 this is
enetFastEnet (10).
• Local segment indication. This indicates whether the sender is on
the same ethernet segment or across a bridge.
• The current state of the auto-topology packet’s sender.
The 7190 listens for auto-topology packets from other nodes and uses
these to maintain tables of information about the other nodes on the
segment. Network management applications use SNMP to access
such tables throughout the network to provide current topological
information to the network administrator. The MIB tables contain the
information list above plus the following
• The slot on which the packet was received. For the 7190 this is
always “1.”
• The port on which the packet was received. For the 7190 this is
always “1.”

IP addresses. When the value any is used for
<ip address>, the
community string can be used by all IP addresses.
