I successfully replaced my DGS-1100-24 switch with a 26 port Cisco SG200.
There is however one issue with the remaining; attached dlink switches that were configured to use a management vlan do no longer obtain a dhcp address. This was working fine before swapping the switch.
The SG200 is working fine it self using management vlan 10 it obtains an IP address. All other defined vlans work fine for connected devices, they all get dhcp addresses. Only where a switch is attached all vlans are parsed ok only the management vlan on the switch does not get an IP.
Tried several approaches, given the fact that it worked fine it should be something with the SG200, tried the following so far without success;
- vlan1 left as default vlan, nothing run over this vlan
- vlan 10 was assigned to the port as tagged and untagged in either case no IP on the attached switch assigned.
The attached switch does however receives all the vlans as an attached unifi access point obtains an vlan 10 ip over dhcp just fine being connected to the switch. Also all the other vlans are working fine on the access point.
Also switching the management vlan of on DGS switch and setting to vlan 10 untagged and pvid to 10 still no dhcp address assigned.
The only thing that works is assigning it a static address than the management interface is reachable. Just like dhcp gets blocked for the switch management interface but not any other connected devices.
Sg200 -> DGS1100-5 -> Unifi access point
vlan10/dhcp vlan10/no dhcp vlan10/dhcp
What could be the difference between a DGS1100-24 and SG200-26 that this does not work any longer.
Any suggestions explaining this behavior would be welcome.
