I'm having exactly the same issue. I've initialized the switch five or six times and each time I've created three additional VLANs (Default is 192.168.1.0/24) and assigned untagged and tagged ports to all of them. I have then created VLAN interfaces with manual IP addresses. (10.10.1.254/24, 10.10.2.254/24, 172.16.1.1/30
Usually, all I see in the routing table is
127.0.0.0 255.0.0.0 Direct 0 127.0.0.1 InLoopBack0
127.0.0.1 255.255.255.255 Direct 0 127.0.0.1 InLoopBack0
192.168.1.0 255.255.255.0 Direct 0 192.168.1.1 Vlan-interface1
192.168.1.1 255.255.255.255 Direct 0 127.0.0.1 InLoopBack0
However, once or twice the switch has added the routes for one of the new interfaces!
10.10.1.0 255.255.255.0 Direct 0 10.10.1.254 Vlan-interface2
10.10.1.254 255.255.255.255 Direct 0 127.0.0.1 InLoopBack0
If I remove the IP address from the interface I can then create a static route but in my case, this route does not appear in the in the 'Summary' section of the 'IPv4 Routing' section, along with the default VLAN details, but instead remains in the 'Configured Static Route Information' section of the 'Create' tab.
Can anyone shed any light on this please? It is very frustrating!
