Enter the module and port number of the port to be viewed. The Interval field can
be toggled among 2 seconds, 1 minute, and suspend. This sets the interval at
which the error statistics are updated. Highlight CLEAR COUNTER and press Enter
to reset the counters.
Port Packet Analysis
To view an analysis of the size of packets received or transmitted by a port,
highlight Port Packet Analysis on the Network Monitoring menu and press Enter.
In addition to the size of packets received or transmitted by the selected port,
statistics on the number of unicast, multicast, and broadcast packets are displayed.
Highlight CLEAR COUNTER and press Enter to reset the counters.
Browse MAC Address Table
To set the MAC address aging time and view the MAC address forwarding table,
highlight Browse MAC Address Table on the Network Monitoring menu and
press Enter:
The Browse By field can be toggled between ALL, MAC Address, Port, and
VLAN. This sets a filter to determine which MAC addresses from the forwarding
table are displayed. ALL specifies no filter.
Note: A very long aging time can result with the out-of-date dynamic entries that
might cause incorrect packet filtering or forwarding decisions. A very short
aging time might cause entries to be aged out too soon, resulting in a high
percentage of received packets whose source addresses cannot be found in
the address table, In this case, the switch will broadcast the packet to all
ports, thus negating many of the benefits of having a switch.
