I've got the following config on my MX75 & MS125s .. these are SW1 and SW2 (VLAN1 is not used for any clients) MX75 P4 - Trunk - to SW1 P1 allowing VLAN 1, 10, 20, 30 MX75 P5 - Trunk - to SW2 P1 allowing VLAN 1, 40, 50 If I look on the Switch status I see.. For SW 1: Port 1 VLAN1 connection to SW2 using IP: 1.1.1.1 Port 1 VLAN1 connection to MX75 at IP: 192.168.128.1 (this is Vlan1 IP) For SW 2: Port 1 VLAN 1 connection to SW1 mac address with no IP address showing (blank) Port 1 VLAN 50 connection 1 to MX75 at : 10.10.50.1 So a few odd things here.. Qt #1: Why is one switch seeing the other switch as a connection on its uplink port (through VLAN1 the native ?) and why 1.1.1.1 Qt #2: why would I see a blank IP address on SW2? Qt #3: Assuming the MX is using virtual interfaces... why do I not see connections on SW1 to the virtual interfaces on the MX (which has 10.10.10.1 & 10.10.20.1 and 10.10.30.1) . SW2 does see 10.10.50.1, but not the 10.10.40.1 .. at least not listed on connections of SW2. Both switches are using DCHP to get management IP from VLAN1 of the mX75 in the range of 192.168.128.x. Just wondering if I've set up the trunks correctly.. I read that VLAN1 should always flow through trunks connected to MS switches..
