Monitoring and Managing Your ELS10-26
ELS10-26 statistics are divided into four groups:
• System statistics
• Ethernet port statistics
• Traffic analysis statistics
• SNMP statistics
You can use this information to analyze your overall network
performance and to make configuration changes as necessary. For
example, Ethernet port statistics can help you identify network
devices that require high bandwidth, and therefore should be
connected through a dedicated, rather than a shared, network
connection. In addition, Ethernet port statistics can help you
identify a network device that is the source of numerous multicast
packets due to a possible malfunction.
4.2.1 Gathering Statistics
For purposes of network management, managed objects must be
identified. Creation of a managed object is achieved by placing its
identifier, and a set of management information appropriate to its
class, in the Management Information Database (MIB).
Using the MIB variables, you can obtain a detailed analysis of your
network by combining statistics for each source network,
destination network, and source and destination port. The
ELS10-26 MIB Reference Guide contains the SNMP MIB variables
you need to monitor and manage the ELS10-26.
4.2.2 System Statistics
For each ELS10-26, the following system statistics are available:
• The number of seconds since the ELS10-26 was last reset.
• The number of spanning tree topology changes that have
occurred since the ELS10-26 was last reset.
