1629.0. "DEFMM-MA 12 or 6 port after using 6 flex channels?" by HGOVC::QCAV01::PANKAJ () Fri Oct 28 1994 03:07

Hi,

	Can  Decrepeater 900 FP (DEFMM-MA) fibre optic repeater module be 
	configured as below:-

	The DEFMM-MA  module has 12 f.o. repeater ports available in the front. 
	Can all the 12 ports be used outside besides having simultaneous access
	to any of the six flex channels available on the dechub.

	Basically we want to use all the 12 ports outside and configure the
	outside connected devices on six flex channels ethernets available on
	the dechub 900. Since this DEFMM-MA is a port switching module, we want
	to connect two ports of this module to each of the six flex channels.
	Can we use all 12 ports on the front or only 6 ports on the front, after
	using 6 hub backplane flex channels ?
	

	Thanx in advance

	Pankaj

1629.1	Use 8 channels with DEFMM?	MINNY::SCHUMACHER	More than cows & chocolate...	`Fri Oct 28 1994 04:11`	9
	I have a further question: We want to use 8 channels of the DEFMM on the backplane. I sucessfully created 8 IMB-Ethernets on the backplane. Then I installed two DEFBA's in the hub and sucessfully connected Ethernets 1-4 on the first, Ethernets 5-8 on the second bridge. Does this really work, and is it supported ? Peter

	>> Can all the 12 ports be used outside besides having simultaneous access >> to any of the six flex channels available on the dechub. The short answer to this question is yes. See notes 1250.*, 1131.11, and 1131.13 for a more detailed discussion. Regards, Rich
1629.3	just 6 for DEFMM	NETCAD::PAGLIARO	Rich Pagliaro, Hub Products Group	`Fri Oct 28 1994 07:16`	5

1629.4	DEFBA can only use 6 Ethernet channels	NETCAD::CARRAFIELLO		`Fri Oct 28 1994 08:48`	8
	Re: .1 The DEFBA can only use 6 backplane Ethernet channels. I don't understand how Hubwatch let you create 8 independent Ethernet backplane channels when there are only 6 available on the Digital Matrix. There must be dual use of some of the channels. Are all of the DEFBA ports in forwarding or are some of them in Backup? Are you also configuring the Backplane Thinwire as one of your Ethernets?
1629.5	You are currently limited to 6 flex Ethernet connections	SLINK::HOOD	I'd rather be at the Penobscot	`Fri Oct 28 1994 09:06`	7
	Keep in mind that HUBwatch and the MAM let you create up to 12 Ethernet backplane segments. However, you can only use 6. When you try to attach anything (current set of products) to the 7th, the connection does not stay put. Tom Hood HUBwatch
1629.6	EF segmentation Question	NCMAIL::ADAIRC		`Fri Oct 28 1994 10:34`	12
	Yet another DECswitch 900EF config question... I have a DECswitch 900EF in the 900MS. I want to create 2 IMB groups, bridge within the IMB group, and then route between the 2 groups using an external router with 2 Enet ports on it. So 2 front bezel ports would be connected to the router ports. Can I easily config the EF so that it bridges IMB1 and IMB2, bridges IMB5 and IMB6, and forces traffic between these 2 groups to go through the router? CA
1629.7	Yes.	SLINK::HOOD	I'd rather be at the Penobscot	`Fri Oct 28 1994 11:12`	1
	Yes. That will take 6 switch ports.
1629.8	How about this?	NCMAIL::ADAIRC		`Fri Oct 28 1994 14:33`	10
	re: .7 I asked the question because all the HUBwatch demos I've seen seemed to indicate there wasn't any "easy" way to essentially segment the bridge itself. Another way to put it is this... I want to assign a bridge port to IMB1 and I want to assign a bridge port to IMB5, but I don't want the IMB1 LAN to see the IMB5 LAN.
1629.9	one bridge. or one switch.	SLINK::HOOD	I'd rather be at the Penobscot	`Mon Oct 31 1994 10:41`	8
	> indicate there wasn't any "easy" way to essentially segment the bridge > itself. Another way to put it is this... If you mean turn the DB900 into two separate bridges, no you cannot do that. Tom Hood HUBwatch

	re: .9 That's what I meant. Thanks.
