2874.0. "filtering on Gigaswitch V.2 using HW V4.1.1?" by SNOFS1::63496::CHIUANDREW () Tue Oct 17 1995 20:39

Hi,

We have some problems in setting up filters in Gigaswitch (v2.2) using 
HUBwatch for windows V4.1.1:

1) We leave the default matrix as the default (all ports can talk to each
other, then we create user defined matrix for virtual lan (i.e. 6.4 can only
talk 10.4,while all other can still communicate, in the PID filter, it
works fine (NO SA/DA filters).

2) Same as 1), but when we create filters for SA and DA, then we cannot
figure out why the filters did not work at all.

We try to filters traffic between 6.4 and 10.4, ONLY IP is allowed between
6.4 and 10.4 for some MAC addresses (e.g. aa-00-04-00-d3-18 and 
aa-00-04-00-01-18).

So we create our own user matrix named mat01 where all ports canNOT talk 
except 6.4 to/from 10.4, then we create pid01 filter which filter ALL other 
protocols except IP (pid=IP, disposition=alwaysforward).
Secondly, we create SA/DA filters using the same matrix mat01, sa01/da01
where sa01/da01=mac_addresses for those devices to be allowed, the
filter disposition=alwaysforward),this setup did not meet what we want
we can ping between 6.4/10.4,  but also to other ports (this we donot want),

could someone clarify how the filtering works (in the manual example, 
M1, M2, M3 and MD, does not say how it match the user define matrix, so
please clarify a bit more).

3) Customer do not want to change the default matrix, because if they 
set it to ALL 0s then it is not easy for them to setup filters to meet their 
requirements, it seems the user defined matrix ALWAYS override the 
PID/SA/DA filters, because in our tests, PID/SA/DA works without user defined 
matrix (I meant we just have a ALL 1s user defined matrix, all ports can
talk), if there any examples that show how to set up filters using different/
same filtering for PID/SA/DA?


In the example, LAVC filtering, it works in our environment, but if we
change it with user define port matrix (i.e. only 6.4-10.4), then it stops
working.


Any hints/ideas?

thanks in advance for help!
