Hello, everybody. My network core consists of a Cisco 2951 router that belongs to XO Communications connected to a Cisco 3750 that basically serves as my distribution switch and an MX100. I have around 500 devices including IP phones, etc. DHCP is presently served by an old Windows 2003 server. We have an MPLS to another location and the way my network is configured I have two cables from the XO router connected to the 3750 and there are another two cables from the 3750 to the MX, i.e. one inside amd one outside. I can only assume it was put together this way for some reason having to do with the MPLS but I don’t really like the design because I feel the functionality of the MX is limited. For some reason the MX can’t translate the MAC addresses for all attached devices so just returns the MAC of the 3750 in many cases. I’d also like to allow the MX to serve as the DHCP server and ultimately I want to replace the 3750 with a Meraki switch, probably an MS350. Does it make sense for me to reconfigure things so the XO router connects directly to the MX, with the 3750 connected inside of the firewall instead of having the MX basically in a loop off the 3750? This seems to be best practice but I’m not sure how to get there from where I am now. I can post a network diagram and configs if it would help. It seems the first goal should be to revise the physical topology then create routes from the MX to the VLANs on the 3750 so they can also be accessed on the MX. Thoughts?
