3071.0. "DECSWITCH900 " by HGOVC::ANTHONYCHIU () Fri Dec 15 1995 04:44

    Hello all,
    
    I got a question from one of our customer and see whether someone
    knows the answer :
    
    Can we use HUBwatch to configure one of the Ethernet port in 
    DECswithch900EF to access only ONE dedicate server by address, ie, all
    the users on this port can only be able to access info on one particular
    server, not ANY OTHERS else.
    
    I know we can set up the filter by address on a particular port by
    granting permission (green arrow) or denying (red arrow) in HUBwatch. 
    However, it is for ONE address only.  If we have, let's say, 4 servers 
    on the LAN totally, does it mean we need to set up the filters for each 
    server individually ie, set up 4 filters for this particular port ?  
    
    I know setting up an virtual LAN can solve this prolem , but as far as
    I know we can't set up v-lan by using HUBwatch. Am I right ?
    
    Appreciate if someone give me the answer.
    
    Merry X'mas

3071.1	VLAN can be done.	CGOS01::DMARLOWE	Have you been HUBbed lately?	`Fri Dec 15 1995 11:38`	10
	How about a diagram as to where the users are and the servers are? If the servers are on the same LAN as the users then there's not too much that can be done. You have to be careful where you place the servers and users in order to set the filters. HUBWATCH does the VLAN creation so you could connect a server and specific users on the same VLAN (ie. 900TP's) and then set filters in place on the 900EF to keep them from getting to other servers. dave
3071.2	Manual filter mode for specific ports allowable I believe	NETCAD::BATTERSBY		`Fri Dec 15 1995 12:44`	6
	The DECswitch 900EF does have a "manual filter mode" that can be selected. This clears the forwarding table for that port, and then manual entries for specific addresses can be entered for that port, thus excluding everything except the desired server's address. Bob
3071.3		SLINK::HOOD	My God, what have I done to my spleen?	`Fri Dec 15 1995 18:42`	8
	Expanding on what Bob said... in the address filters window, set the Manual Mode (bottom set of arrows) button for the port to be filtered (red blocked arrow). This means that everything will be blocked except the MACs you explicitly specify in an address filter. Then create a new address filter entry with the workstation's address. Make sure the arrow is green (forwarding) for that port.
