• Top Talkers: the main pane lists all the
discovered devices that are generating traffic on
the local network segment.
• VLAN Statistics: the main pane lists all VLANs
discovered on the local network segment.
Notes
The number of VLANs discovered by VLAN
Statistics and VLAN Discovery (described
later) frequently differs. VLAN Statistics
monitors the local segment only and
generates a list of VLANs discovered. The
VLAN Discovery test, on the other hand,
uses active SNMP discovery to determine
the number of VLANs on your entire
network.
If the instrument is connected to a port that
is configured with 802.1Q VLAN tagging
and the instrument is not so configured, or
if 802.1Q is enabled on the instrument but
not on the port, DHCP will fail and device
discovery will probably show one device
(This EtherScope). VLAN Statistics, on the
other hand, will show whether any VLAN
tagged packets are on the network
segment. To fix this problem, you should
either disable 802.1Q on the instrument, or
to configure the instrument for the correct
VLAN (try configuring the instrument for
the VLAN with the highest packet count).
See “802.1Q/IP TOS Settings” on page 76
for details.
