Stratrix 5700

[XavierParticipantKarma: 11Rank: Padawan]

Hello,

I have bought few Stratix 5700 switches to connect few PLCs in plant to the central PLC server.

All PLCs will be connected with this switch via CAT6 and uplink port will be connected to server via fiber optic cable. This is my first time working with fiber optics.

• Once I finish express set up in the device manager, do i need to configure SFP module dual port ?
• How can configure fiber optic port ?
• Is express set up is enough to use fiber optic port ?

Your help will be much appreciated !

 

Thanks,

Raj

Hi Raj and welcome to the forums!

Make sure your SFP port is Cisco compliant.

Fiber SFP available for Stratix 5700 switches are:

• 1783-SFP100LX Stratix Fiber SFP, 100 Mbit connectivity over single-mode fiber
• 1783-SFP100FX Stratix Fiber SFP, 100 Mbit connectivity over multi-mode fiber
• 1783-SFP1GLX Stratix Fiber SFP, 1000 Mbit connectivity over single-mode fiber
• 1783-SFP1GSX Stratix Fiber SFP, 1000 Mbit connectivity over multi-mode fiber

They function as a combo port, so you can use copper or fibre for you Gigabit uplink (i.e., Gi1/1 and Gi1/2). Depending on your setup you will configure them to suit.

Visit the Network Essentials video series to give you some tips.

Good luck!

Thank you.

Yes, I have bought following SFP module to use with single mode fiber optic network.

–  1783-SFP1GLX Stratix

Do you have a video, which shows how to set up fiber optic combo port ?

Hi Raj,

There are no special configurations for the SFP combo ports. It’s a one or the other type setup, meaning, you have the option to use copper for Gi1/1 and Gi1/2 or fiber. They are the same logical connection, with two different physical connection options (copper of fiber). Maybe I’m not understanding your question, but as for any special configurations to use the SFP module, no, just pop it in and it will now be the connection point for your Gigabit ports.

Thank s a lot ! I got it ! (No special configuration for SFP module / Just plug in & play)

One more question:

Does Stratix 5700 (1783-BMS10CGA) support Spanning Tree Protocol ?

Can I connect Stratix 5700 switches in mesh network topology ? Do I need to do special configuration for port priority ? (Like switch should pick up which port once current network line breakdown)

Can I connect FE SFP port to one end of switch & GE (combo port) SFP port to other switch ? Would it work ?

I really appreciate your answers & thankful to this forum !

Hi Raj, glad we’re getting somewhere. Yes, the Stratix 5700 supports three different spanning tree protocols. I have implemented in different mesh type scenarios with Cisco backbone switches. The three Spanning Tree protocols are as follows:

Multiple Spanning Tree Protocol (MSTP) based on the IEEE 802.1s standard. MSTP uses Rapid Spanning Tree Protocol (RSTP) for rapid convergence. This mode maps a group of VLANs into a single spanning tree instance, with each instance having a spanning tree topology independent of other spanning tree instances. This architecture provides multiple forwarding paths for data traffic, enables load balancing, and reduces the number of spanning tree instances required to support a large number of VLANs. MSTP is the default STP mode.

Per VLAN Spanning Tree Plus (PVST+) protocol based on the IEEE 802.1D standard. PVST+ runs on each VLAN on the switch up to the maximum supported, to help create a loop-free path through the network. PVST+ provides Layer 2 load balancing for the VLAN on which it runs. You can create different logical topologies by using the VLANs on your network to make sure that all of your links are used but that no one link is oversubscribed. Each instance of PVST+ on a VLAN has a single root switch. This root switch propagates the spanning-tree information associated with that VLAN to all other switches in the network. Because each switch has the same information about the network, this process maintains the network topology.

Rapid per VLAN Spanning Tree Plus (Rapid PVST+) protocol based on the IEEE 802.1w standard. RPVST+ is the same as PVST+ except that is uses a rapid convergence based on the IEEE 802.1w standard. To provide rapid convergence, the rapid PVST+ immediately deletes dynamically learned MAC ID entries on a per-port basis upon receiving a topology change. By contrast, PVST+ uses a short aging time for dynamically learned MAC ID entries. Only one version can be active on the switch at any time. For example, all VLANs run PVST+, all VLANs run rapid PVST+, or all VLANs run MSTP.

I’m not familiar with the GE switch you speak of, but as long as it supports one of these standards you shouldn’t have any problems. Here is a link to the full Stratix User Manual.

Thanks a lot ! Really appreciated !

I understood this: Stratix 5700 supports here spanning tree protocols so it supports mesh network between switches.

Do I have to configure to tell switch that which STP protocol it should use ? or it decide by itself ?
(MSTP, PVST+, Rapid PVST+) ????

The 5700 uses MSTP out of the box by default.  If you want to use another protocol, you have to configure that protocol on the 5700.
