C3900 Switching creating a network redundancy with 2 Servers Netra SPARC S7-2

[registos]

hello,

i will have this topology and i will use the C3900 sw with this module : C9300-NM-4G.

i searched and i did not found any relevante information about this C9300-NM-4G + SFP Transceiver.

The only information is on Cisco page, mention that the module  C9300-NM-4G are natively GigabitEthernet and are configured GigabitEthernet1/1/1.

My question is this module + SFP which is tranditional used for uplinks , can be easly used for this kind of redundancy of L2 protocols or even for L3 protocols  ?

thanks

Cat 9300 can be done Layer 2 or Layer no issue.

if you adding a new Cat 9300, why not stack them ( so Logically 1 ), so you get more resilience in the setup - Hope this solution works.

My question is this module + SFP which is tranditional used for uplinks , can be easly used for this kind of redundancy of L2 protocols or even for L3 protocols  ?

yes, can be used.

Hello,

thanks for your quick anwser.

and

Thanks for your advice, about the stack.

that approach can change the design reducing the number of the switch and still have redundance to my app server.

can be a good choice, if that solution provide me one way to do less configuration on L2 redundancy STP and on L3 redundacy (HSRP) or best of the two worlds do not set-up any L2 STP neither L3 HSRP on the switch and using the management of the stack to do it !?

With that stack solution it's possible reduce the settings at minimum ?

and please advice me if this SFP transceivers fiber ports admit L2 vlan's set-up and routing protocols ?

the new design using the stack cable:

thanks in advance

With that stack on the cisco side you do not have L2 loops or required HSRP - since you are stacking - this cisco switch point of view.

we are not covered on the sun server-side, you need to get expert advice from the Sun server (how their backplane designed).

If you got 4 port NM Module - so any 1GB SFP should able to work for you. ( depends on where the Server Located, - i mean distance).

here is less configuration required - Layer 2 port-channel towards each sun Server side, which allows respected VLAN in that port-channel.

when you stack Cat 9300

the port-number changes  as example :

Switch 1 - 1/1/1

Switch 2 - 2/1/1
