| For the 900-series bridges/switches (DECbridge 900MX, DECswitch 900EF,
DECswitch 900EE, PEswitch 900TX, RoamAbout access point), the filter screen
consists of zero or more filter entries, one per MAC address or per protocol
type. Each filter entry has three main elements: (1) the address or protocol
(2) whether that address or protocol is forwarded or filtered per port,
and (3) whether that address or protocol is rate-limited on broadcast.
Typical filter entry:
1 2 3 4 5 6 7
+-------+
| | | | | | | 0E-32-04-90-33 | ==O-> |
| | | V | V | K-MARTnet +-------+
V V V - V - V
For this entry, K-MARTnet is filtered from ports 4 and 6, and can be
forwarded to the other ports. For broadcast, rate limiting is enabled
for this protocol (rate limit is shown by the box at the right).
There is also a Manual Mode / Defaults box at the bottom of the Address
Filters and Protocol Filters screen which says, "If I haven't specified
a particular address or protocol in any entry above, this is what to do
with it." It uses the per-port arrows used in the filter entries.
To add a new filter entry, press the big "+" button on the right side of
the filters window. To modify an entry, select it, then press the modify
pushbutton (picture of an arrow being replaced by a different arrow). You
can only modify entries through the modify function, not directly in the
filters window [this is a slight inconvenience, but was the only way I could
think of to verify the validity of the modified entry]. For the address
filters, you cannot delete or modify the entries for the spanning tree
addresses nor the MAC addresses of the ports themselves.
As far as 7 arrows across and 14 arrows down, I don't know what you mean.
For the agents file, HUBwatch for Windows will only access an agents file
located in the HUBWATCH_LIBRARY directory. Check how you've got that
environment variable defined. Change its definition if you want to use
a different directory for the agents file. From your question it looks
like HUBWATCH_LIBRARY is defined as C:\HUBWATCH\USERDATA\. If you don't
want your agents file there, redefine HUBWATCH_LIBRARY. Otherwise, check
the protections on that directory.
[HUBwatch for OpenVMS VAX uses the logical HUBWATCH$LIBRARY, defined by
default as "SYS$LOGIN" for this same purpose. In HUBwatch for DEC OSF/1
and HUBwatch for ULTRIX, it's HUBWATCH_LIBRARY, which users must define.]
