Ubiquiti EdgeRouter to EdgeSwitch LACP(LAG) Configuration

Networking & Firewalls
1

Hey all,

First @LTS_Tom thanks for all the videos.

I’ve been working on setting up a LACP connection between an EdgeRouter ER12 and an EdgeSwitch ES-24-250w. I started with the Ubiquiti article here. I started with the router from a fresh state, with no firewall rules.

The interfaces included in the bond0 are eth4-eth7

Below are the subnets:

ubnt@EdgeRouter-12# show interfaces bonding bond0
 address 10.20.50.1/24
 description "Network Equipment"
 hash-policy layer2+3
 mode 802.3ad
 vif 1 {
 }
 vif 60 {
     address 10.20.60.1/24
     description "Production Servers"
 }
 vif 70 {
     address 10.20.70.1/24
     description "wired Hosts"
 }
 vif 80 {
     address 10.20.80.1/24
     description "Internal WiFi"
 }
 vif 90 {
     address 10.20.90.1/24
     description "IoT WiFi"
 }
 vif 91 {
     address 10.20.91.1/24
     description "Guest WiFi"
 }

Traffic appears to be routing properly but I can’t get DHCP services to work properly. I have set the following on the edge router:

ubnt@EdgeRouter-12# show service dhcp-server shared-network-name
 shared-network-name WiFI {
     authoritative disable
     subnet 10.20.80.0/24 {
         default-router 10.20.80.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.80.100 {
             stop 10.20.80.150
         }
     }
 }
 shared-network-name Guest_WiFI {
     authoritative disable
     subnet 10.20.91.0/24 {
         default-router 10.20.91.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.91.100 {
             stop 10.20.91.150
         }
     }
 }
 shared-network-name IoT_WiFI {
     authoritative disable
     subnet 10.20.90.0/24 {
         default-router 10.20.90.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.90.100 {
             stop 10.20.90.150
         }
     }
 }
 shared-network-name Network_Equipment {
     authoritative enable
     subnet 10.20.50.0/24 {
         default-router 10.20.20.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.50.100 {
             stop 10.20.50.150
         }
     }
 }
 shared-network-name Production_Server {
     authoritative disable
     subnet 10.20.60.0/24 {
         default-router 10.20.60.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.60.100 {
             stop 10.20.60.150
         }
     }
 }
 shared-network-name Wired_Hosts {
     authoritative disable
     subnet 10.20.70.0/24 {
         default-router 10.20.70.1
         dns-server 208.67.222.222
         dns-server 208.67.220.220
         lease 86400
         start 10.20.70.100 {
             stop 10.20.70.150
         }
     }
 }

I have tried different hash types, Layer2 and Layer2+3. I’ve tried the ports in the switch group but that breaks the LAG connection. I’m not sure if I need to do some kind of DHCP Relay or what.

Well I happy to hear anyone thoughts,

Thanks,
MJ

None of us here at my office really work with Edgerouters very often, I would try their forums.

Thanks Tom,

I have already placed a post in Uniquiti’s community but it did not seem to get much interest. I guess LAG on their routers is one of those things where they developed it enough to say that it can do it and left it at that.
