Alcatel Unleashed

Hi can anone assist with this questions.

If I install 4 6450s in the same location (cabinet) I would need 1 x os6540 xni u2 module plus relevant stacking cables.

If a 5th and 6th os6450 were deployed in two new areas can you use the sfp ports to remotely stack or would you simply have to connect them and tag the relevant sfp ports to 'connect ' the remote switches.

If they can would you/can you install a redundancy fibre link back to the primary switch.

I ask this as I saw comments on the web this may be available in new software. ?

Thanks in advance.

All stacking (also remote) has to be done on the dedicated stack ports (OS6450-XNI-U2) on the back of the switch not on the 10G on the front. Only exemption is the 6450-10 which uses builtin ports.

(at least this is what the HW Guide is mentioning) AFAIK AOS7/AOS8 support (should support) something different

Thank you for your reply.

So if I'm stacking locally and have a remote switch I would use the local stacking principle to integrate the new switch ie A to B to A etc with a redundancy link back ?

Regards

I don't understand the question.

If you want to integrate the remote switch in the stack (hence only one management IP, single view to all ports) you would install it just like any other stack-member, but use SFP+ instead of DAC.

If you just want to connect it to the stack you could choose LACP/whatever fits your need.

Again thank you for your reply.

The point ives making if I had 3 switches in one location and wanted to stack them I would use the expansion module xni U2 to connect A to b to A etc

If I wanted to connect a 4th switch which is located remotely again I would purchase xni u2 module and interstate with the main stack with SFp connectors via fibre link. Again using the A to B to A principle.

DACP ? - direct cable ?

LACP local area ??

DAC: Direct Attach Copper - the 10G Stacking cables
LACP: Link Aggregation Control Protocol

If you have 3 Switches in a stack connected
1 Port A -> 2 Port B, 2 Port A -> 3 Port B, 3 Port A -> 1 Port B

You add a 4th switch and afterwards have
1 Port A -> 2 Port B, 2 Port A -> 3 Port B, 3 Port A -> 4 Port B, 4 Port A -> 1 Port B
With the connection 3 -> 4 and 4 -> 1 being 10G SFP+

again thank you for the information.

one last one, just our of curiosity I have another potential deployment with 2 switches. i want to connect them via the sfp ports at the front of the switch (using trunked/tagged ports). what type of GBIC would be required (this is for 2 x 24 port 6450 switches) ?

The ones that match your needs
Do you want 10G (and have the 10G Licence/6450X?) - SFP+ that match your distance/Fibers, either Multimode (SFP-10G-SX) or Single mode (SFP-10G-LR) if they are directly next to each other you can use 10G Copper - SFP-10G-C.3

Same for Gigabit .. use the SFP that match you distance/fiber check compatibility in http://enterprise.alcatel-lucent.com/as ... 1_revC.pdf

Excellent advice many thanks
