The IRM2 Chassis View
Port Type
If you choose Port T
ype, each port status box will display that port’s topology
status: station or trunk. A station port (displayed as STA) is one which has zero or
one source addresses in its source address table; a trunk port (designated TRK)
has two or more source addresses in its table. If a board does not support the Port
Type option, its port status boxes will remain blank. For more information about
the source address table, see Chapter 4, Source Address Functions.
Status
You can view three status categories for your ports, which reflect six possible
Admin/Link, Admin, or Link status conditions:
• Admin/Link — ON, OFF, SEG (segmented), or NLK (not linked)
• Admin — ON or OFF
• Link — LNK (link), NLK (not linked), or N/A (not available)
If you have selected the A
dmin/Link status mode, a port is considered:
• ON if the port is enabled and has a valid link.
• OFF if it has not been enabled or if it has been disabled through management
action.
SEG (segmented) if the port has been enabled by management and has a valid
connection, but has been segmented by the repeater because 33 consecutive
collisions have occurred on the attached segment, or the collision detector was on
for more than 2.4 µs.
NOTE
In NetSight Element Manager, the polling interval is set via the Tools—>Options
window available from the primary window menu bar.
Refer to the NetSight Element Manager User’s Guide for full information on setting
device polling intervals.
