NetStacker NMM Lite Installation Guide
Group Parameters
Use to assign to a segment or isolate, meaning assign to no seg-
ment, a group. (A group is defined as all of the ports on a
NetStacker hub module.) Pressing
n (Select Next Group)
repeatedly cycles through the group choices. Pressing
s
(Assign/Isolate Group Segment) repeatedly cycles through the
segment choices—1 or Isolated for the NetStacker hub.
If you isolate a group (that is, assigned it to no
segment), you’ll lose your Telnet connection and
SNMP capabilities. You then can manage the
group only by using AsantéView Out-of-Band.
If you isolate the NMM Lite (that is, assigned it to
no segment), your AsantéView Management Sta-
tion (AMS) will not be able to communicate with
the NMM Lite. You’ll lose your Telnet connection
and SNMP capabilities.
You can reestablish communication with the
module by using AsantéView Out-of-Band or by
using the RS232 connector as a local manage-
ment port.
Port Parameters
Use to enable/disable a specific port’s connection, link integ-
rity, and auto polarity testing. Pressing
N (uppercase N) repeat-
edly cycles through the available groups. Pressing
n repeatedly
cycles through the ports within a group.
Node Summary
Use to display a summary of node activity on the hub. The hub
monitors all packets passing through its ports. Pressing
G or g
cycles back and forth through the available groups. Pressing
P
or
p cycles back and forth through the ports within a group.
Pressing
c (chg cntr) repeatedly cycles through the available
data counters: Good Frames, Bad Frames, Broadcast, Multicast,
Short Event, Runts, Frame Too Long, SFD Missing, Fragments,
Alignment Errors, DRM Errors, IFG Errors, Collisions, Late Col-
lisions, Auto Partitions, MJLPs, and Readable Octets.
Pressing
a sets the node summary aging time, which is the
amount of time the hub stores node summary data. Each time
a new device uses a port, or the frame type changes, the hub
stores an entry in the Node Summary log. If the hub does not
receive data again from that node within the specified aging
time, the node data is purged from the log.
