Viewing RMON Information
Viewing RMON Information
RMON information includes:
• Ethernet port statistics and history data that you can view from the CSS
through show commands.
• Alarm event notifications that are sent to log locations on the CSS or an
SNMP network management station. Refer to Chapter 5, Configuring Simple
Network Management Protocol (SNMP), for information on configuring
SNMP on the CSS.
The following sections provide information on:
• Viewing Statistics
• Viewing History
• Viewing Events in a Log File
Viewing Statistics
RMON statistics provide a summary of data received over the Fast Ethernet or
Gigabit Ethernet ports. You can view RMON statistics either in a CSS CLI session
through the show rmon command, the show ether-errors command (refer to the
Cisco Content Services Switch Routing and Bridging Configuration Guide), or
directly through an SNMP network management station by using ether-stats MIB
objects (refer to RFC 1398).
The CSS show rmon command allows you to display the extended 64-bit RMON
statistics for a specific Ethernet port or all Ethernet ports in the CSS. The CSS
Enterprise ap64Stats MIB defines these statistics. You can also display the RFC
1757 32-bit statistics by adding the -32 suffix to the show rmon command.
To display the RMON statistics for all ports in the CSS, enter:
# show rmon
To display the RFC 1757 32-bit statistics, enter:
# show rmon-32
To display the RMON statistics for a specified port in the CSS, enter:
# show rmon
