Redundancy with 3750

[palomacasimir]

Hi,

I have some problems to link up 3750 with the following configuration.

In fact, i have 2 products generating Multicast flows (1 Main & 1 standby).

1 is connecting to 1 C3750 Main

1 is connecting to 1 C3750 Standby

Port 7 of the C3750 Main is connected to an optical switch (the main unit)

Port 8 of the C3750 Main is connected to another optical switch (the standby unit)

Port 7 of the C3750 Standby is connected to an optical switch (the standby unit)

Port 8 of the C3750 Standby is connected to another optical switch (the main unit)

The goal is to switch both optical switches in the same time, but i have 2 differents phenomenas. If i switch from the main to BU, both links are present.

If i switch from the BU to the main, 1 of both links is present and the other disappears.

Hello,

your physical setup is two 3750 switches, of which both have a connection to two optical switches, one standby, and one main unit, which gives us a total of 4 optical switches ?

How are your 3750 switches connected ? And what is the brand/manufacturer of the optical switches ? I guess I am asking in order to find out how the spanning tree is working; switches usually mean spanning tree...

Is it possible to post the configurations of the 3750 switches ?
