The MX67C/MX68CW contains a 3G/4G modem which can be used for cellular failover (3rd WAN interface-ish). Otherwise, no. All MX'es support only 2 WAN interfaces. MX250 and up, have two dedicated ports. MX100 and below, has one dedicated port, and one shared, which can be converted. ... View more

Every time I'm in a situation where I need to clear a DHCP lease on Meraki, I hit this button so hard... There is no way (that I know of) to clear a DHCP lease manually in Meraki. Best is to lower lease time, in the DHCP server, and wait for the leases to renew, to the shorter lease time.  ... View more

@MerakiDave wrote: If I understand the earlier power question correctly, then no, the MR30H should require 3at power on its uplink port in order to come up AND be able to pass through 3af power on port 1.  It should NOT be able to uplink with 3af power and simultaneously have 3af passthrough on port 1. That is also what I meant, I believe. I was just unable to word it properly. Thanks. 🙂   Inorder to power 3af out it's LAN ports, it must be power itself with 3at. 🙂 ... View more

@DrewF; If the LAN port is set to the same VLAN as AP management, you could run an Guest SSID with MEraki DHCP on a daisy chained AP. I think. Without having tested it. Meraki DHCP NATs directly on the AP, with the APs mgmt IP address.    So assuming your AP mgmt vlan is 10, setting that as access port on the MR30H LAN port, would allow for the daisy chained AP to NAT to that address and vlan.  Again, without having tested it. ...

I had a discussion with a customer and Account Manager the other day, whether this was possible or not, and whether the solution would be "good". From what I read, the MR30H requires 802.3af but with .3at recommended, and gives .3af out the LAN ports. The customer is having a scenario where he would like to run two MR30H in daisy chain from one switch, rather than running them both down to the switch.   I kept trying to say that I doubt it would work, yet I was unsure completely. Usually the AM only hears "maybe" and automatically assumes that as a "sure, it works".  ... View more

@kusumanegarait wrote: @PhilipDAth. Yes, of course, my switch port is configured trunk port. In this case, VLAN 100 is my native VLAN. So, can the client connect to the SSID with tagged VLAN 100? Although it can be done by configuring with untagged VLAN. If VLAN 100 is native on the switchport (untagged), then remove the VLAN tag on the SSID page.    ... View more

How is the switch on which the AP is connected, configured?    Since you are tagging packets with VLAN 100, you need to make sure that VLAN 100 is configured on the switches.  ... View more

Assuming the MX acts as DHCP server, you could setup Option 3, to point your Default Gateway to another host.    Creating an interface on the MX will always make it Default Gateway, unless your instruct your clients otherwise, via. e.g. Option 3.      ... View more

TLV values for the Option 43 suboption: Type + Length + Value. Type is always the suboption code 0xf1. Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex. For example, suppose there are two controllers with management interface IP addresses, 192.168.10.5 and 192.168.10.20. The type is 0xf1. The length is 2 * 4 = 8 = 0x08. The IP addresses translates to c0a80a05 (192.168.10.5) and c0a80a14 (192.168.10.20). When the string is assembled, it yields f108c0a80a05c0a80a14. The Cisco IOS command that is added to the DHCP scope is option 43 hex f108c0a80a05c0a80a14.  [link]   In your case; Type: 0xf1 Length: 0x04 Value: 0x0a.0x00.0x01.0xc9   Therefore; f1040a0001c9 ...

I have a network topology where, oddly enough, I have a problem with STP actually doing its job - blocking ports. I wanted to experiment with if LACP would do some loadbalancing between the two switches, or maybe gain some bandwidth on the uplink, as well as not block ports. So far, even LACP is blocking traffic on one of the links. ... View more

I am currently deploying this network topology, although with a single ISP only. Using multiple switches in the WAN breakout network (VLAN) you need to keep an eye on your STP. Because I am basically implementing multiple tiered network loop, I having a problem net STP actually doing its job, and thus blocking all WAN links to my Warm Spare MX. In order to keep my secondary MX online, I have to disable RSTP on one port, so as it doesn't go into a blocking state. ... View more
