I was asked what I think about the proposal to link one EX series switch with 6x 1 Gbps CAT6 copper interfaces in a 802.1ad link aggregation group to another existing EX access switch Virtual Chassis from the same model. The reason is saving time and money. They want to connect 8 PC’s but there are only 6x CAT6 cables to the existing EX series Virtual Chassis Access switches in the Satellite Equipment Room available.
The existing LAN has the rather common spine leaf topology, just about as displayed in the sketch below, but with the absence of the core layer switches and with a lot of layer 2 vlans. The (orange) Distribution switches are coupled together with 2x fibre LAG interfaces to form a Virtual Chassis.
The distribution switches have the lowest rstp bridge priority, the (blue) access switches have a higher bridge priority (rstp enabled on all interfaces). The new ex series switch shall be configured with the highest bridge priority of all. There is no BPDU-, loop-, or root protection. Storm control is enabled on all the switches.
What do you think about this proposal?
With regards,
Jean
