Fast Ethernet
Interface Modules (FE-PIM): The SmartSwitch 6E12x-26 has
two FE-PIM slots for optional 100Base-TX/FX connectivity. The
following FE-PIMs are available depending upon the on the media
type needed:
FE-100TX -- RJ45 Connector FE-100FX -- MultiMode Fiber, SC Connector
FE-100F3 -- Single Mode
Fiber, SC Connector
Remote Monitor (RMON):
The SmartSwitch 6E12x-26
fully supports all Ethernet
RMON groups -- Statistics, Alarms, Events, History, Host, HostTop'n,
Host Matrix, Filter, and Capture. The Statistics, Alarms,
Events and History groups are enabled on all interfaces simultaneously
by default. The Host, HostTop'n, and Host Matrix groups are disabled
by default and may be enabled on all interfaces simultaneously.
The Capture and Filter groups are disabled by default and may
be enabled on any two interfaces simultaneously.
RMON Actions: Cabletron
has developed a vendor specific extension to RMON referred to
as RMON Actions. RMON Actions allows for the ability to set an
"Action" on any SNMP MIB OID variable. The "Action"
can be triggered by any RMON Event and/or Alarm. The "Action"
can be, for example, to turn a MIB-2 Interface off if a Broadcast
Threshold is crossed.
Broadcast Suppression:
The 6E12x-26 supports the Broadcast Suppression feature. This
enables, on a per port and packet per second basis, the ability
to restrict the amount of received broadcast packets to be forwarded
out other interfaces. All broadcast packets received on the
configured interface will be forwarded to all the other interfaces
up to the threshold. Any broadcast packets received above that
threshold will be dropped. In the event Broadcast frames are being
suppressed, Multicast and Unicast traffic continues to flow unaffected.
Runtime Address Discovery:
Allows the SmartSwitch 6E12x-26 to discover its own IP Address
and Subnet Mask. The SmartSwitch 6E12x-26 requests an IP address
from the network, via the BOOTP and RARP protocol, if there is
not an IP address configured. If a RARP/BOOTP response is received,
the SmartSwitch 6E12x-26 will save the IP address to Non-Volatile
RAM and assign a Subnet Mask to match the class of the IP address
received.
Port Mirroring:
This feature allows a user to map source port(s) to desired
destination port(s) in order to utilize a remote analyzer or RMON
probe. This feature works at a bit copy level allowing the analyzer,
connected to the destination port, to appear as if it is directly
connected to the LAN segment of the source port(s).
SmartTrunk:
The SmartTrunk feature allows the user to logically group interfaces
together between devices. All interfaces in this logical grouping
are active allowing greater bandwidth between devices. As long
as both devices support the SmartTrunk feature, any amount of
interfaces can be combined to create a logical interface.
System Resources View:
This feature allows a user to view the current resources of
the SmartSwitch 6E12x-26 such as CPU utilization, switch utilization,
and the amount of installed vs. available memory.
IP Fragmentation:
This feature allows FDDI IP frames larger than 1500 bytes of data
to be fragmented in to multiple Ethernet frames provided the "do
not fragment bit" is not set within the frame. Fragmentation
in the SmartSwitch 6000 is provided by the module containing the
egress port for each frame. By default, IP Fragmentation is enabled
and any module in the SmartSwitch 6000 chassis is capable of IP
fragmentation. If a user wishes to disable IP fragmentation on
a chassis wide level, IP fragmentation must be disabled on each
SmartSwitch module installed in the chassis. To disable IP fragmentation,
consult the Users Guide supplied with the SmartSwitch 6E12x-26.
Local Management: Access
to the Local Management application is available via the SmartSwitch
6E12x-26 's COM port or in-band using a TELNET session. Local
Management enables the configuration of IP address, subnet mask,
default gateway, trap addressing, TFTP download parameters and
high speed interface parameters. The SmartSwitch 6E12x-26 also
supports "Flash Download" and "Clear NVRAM"
features via the Local Management application. The default community
name/console passwords for all access levels is public.
Uninterruptible Power Supply
(UPS) Management: American
Power Conversion Uninterruptible Power Supplies can be monitored
and controlled by the SmartSwitch 6E12x-26 . To connect the UPS
to the SmartSwitch 6E12x-26 , use Cabletron part number 9372066
(DB9 to RJ45 adapter) and a straight through RJ45 to RJ45 cable
(Cabletron part number 9360005-xx).
Firmware Downloads:
The SmartSwitch 6E12x-26 supports two methods of installing
new firmware images. The Runtime Download application allows the
module to continue to operate while downloading a new firmware
image through any network port. The SmartSwitch 6E12x-26 will
then continue to use the original firmware image until the device
is reset. The Standard Download application automatically disables
the module while the new firmware image is downloaded through
any Ethernet front panel port and resets at the successful completion
of the download.
In the event that a Runtime Download
is interrupted the firmware image in flash memory will have been
erased. The SmartSwitch 6E12x-26 will continue to operate using
the original firmware image until it is reset. If the device is
reset prior to a successful Standard Download or Runtime Download,
then SmartSwitch 6E12x-26 can initiate a firmware image download
from a BOOTP server ONLY! Although Runtime Download is
a powerful firmware management feature, careful consideration
should be given to both the timing (best when network usage is
lowest) and network stability (especially downloads over a WAN
link) at the time of the planned download.
Two versions of the same firmware
image are shipped with each 6E12x-26 . The file suffixed with
.hex (after it has been decompressed from a .zip file)
is for the Standard Download. The file suffixed with .fls
(after is has been decompressed from a .zip file) is for the Runtime
Download.
In general, a SmartSwitch 6E12x-26
will be shipped to you already configured with this version of
firmware installed. If you have an existing SmartSwitch 6E12x-26
with firmware versions below 01.01.01 that you wish to have upgraded,
follow the TFTP download instructions that are included with your
User's Guide.
If installing FE-100XX Modules
(FE-PIMs) in the SmartSwitch 6E12x-26, apply forward pressure
to the face plate of the unit while aligning the connector of
the FE-PIM with the connector on the 6E12x-26. Caution must be
used to prevent the bending of the FE-PIM connector Pins on the
6E12x-26. If further
assistance is needed, Please call Cabletron System's Technical
Support department @ (603) 332-9400
If the SmartSwitch 6E12x-26 needs
to transmit a management packet to an IP destination that has
never been contacted before (or has not contacted the SmartSwitch
6E12x-26 previously), the SmartSwitch 6E12x-26 will execute
an ARP Request packet. This ARP Request will be transmitted out
all interfaces and the SmartSwitch 6E12x-26 will learn which
of it's ports can be used to contact the destination station.
If this station's ARP entry ages out or if the station is moved
to another port, subsequent ARPs will only be transmitted
out the port that originally connected to the destination, and
not out all ports. This results in an inability to initiate
contact with a relocated station again until the station begins
to transmit on the new port, at which time the SmartSwitch 6E12x-26
will learn its new location.
Any associated problems found outside
this list should be directed to Technical Support at Cabletron
