Preseem and Switches in switch centric design
Anyone who follows me knows I am a big fan of switch centric designs. This usually involves a router on a stick paired with a high port count switch. Recently I had a client that installed a Preseem appliance in their network.
Equipment used in this setup
-Dell R710 with a 4 Port SFP+ card running Preseem
-Cisco 3064-X 48 Port switch
-Maxxwave Vengeance router with dual QSF+ card and 4 Port SFP+ card
A visio diagram of how this looks
We have two transport links coming into the switch on the left. These are dumped into VLANs 506 and 507. We then come out of the switch into the Preseem box via 2 SFP+ ports, one for each VLAN. In this case, we just used DAC cables In the future, we can turn these into trunk ports to pass more VLANS through.
The data then leaves the Preseem box over dual SFP fibers directly into the router’s SFP+ ports. If the Preseem appliance fails we have a secondary OSPF/IBGP path from the router’s 40 GIG QSFP down to the switch. This is a bypass in case the Preseem appliance hardware fails.
If you start flowing more than 10 Gigs through a single link you can upgrade to more SFP+ ports into your appliance and a 40 Gig QSFP+ card. You then link the appliance to the spare QSFP port on your router.
