Performance Monitoring Overview
The Internet Appliance (IA) is a full wire-speed Layer-2, -3 and -4 switching router. As
packets enter the IA, Layer-2, -3, and -4 flow tables are populated on each line card. The
flow tables contain information on performance statistics and traffic forwarding. Thus the
IA provides the capability to monitor performance at Layer 2, 3, and 4. Layer-2
performance information is accessible to SNMP through MIB-II and can be displayed by
using the l2-tables command in the CLI. Layer-3 and 4 performance statistics are
accessible to SNMP through RMON/RMON2 and can be displayed by using the statistics
show command in the CLI. In addition to the monitoring commands listed, you can find
more monitoring commands listed in each chapter of the Internet Appliance Command Line
Interface Reference.
To access statistics on the IA, enter the following commands in Enable mode:
Show all TCP/UDP connections
and services.
Show all IP routes.
Show all MAC addresses currently
in the L2 tables.
Show info about MACs residing in
a port's L2 table.
Show all L2 flows (for ports in flow-
bridging mode.
