BL1300 limit on number of interfaces?

artmg · 2019-05-19T19:18:00.651Z

Hi I am using a GL1300 as an additional Wifi Access Point on a network with multiple SSIDs and associated VLANs for secure separation of traffic. Using the LuCI interface I have successfully set up the configuration, and most of the SSIDs work except one. The client initiates a connection to the SSID which seems to work, but then it gives up.

I have noticed something odd in the LuCI / Network / Interfaces / Interface Overview page, that the interface for this network does not come up, and it does not obtain an IP address via it’s DHCP client. Here is an example of the page output:

Network	Status
IFVLAN120 () br-ifvlan120	Uptime: 2d 5h 46m 17s
IFVLAN150 () br-ifvlan150	Uptime: 0h 0m 0s
IFVLAN80 () br-ifvlan80	Uptime: 2d 5h 46m 17s
IFVLAN90 () br-ifvlan90	Uptime: 2d 5h 46m 17s
WAN eth0	Uptime: 0h 0m 0s
WAN6 eth0	Uptime: 0h 0m 0s
LAN () br-lan	Uptime: 2d 5h 46m 20s

As you can see it is the VLAN150 which does not accept connections, the other 3 SSID/VLAN combos work just fine. I have checked and they appear to be configured in a similar manner, including the bridge between the VLAN Interface and the 2 Wireless Networks (1 per radio).

They are all set to Bring Up on Boot so I am wondering if there is some other reason why the interfaces do not come up. Is there a hardware or software limitation on the number of interfaces that can be configured?

Please let me know if you want any other config detail to assist in diagnostics
Thanks for taking the time to read through and respond to my issue.

The first question I’d ask is if you’ve got something connected to the “WAN” port of your router. It’s OK if you don’t, just helpful to know what is expected to be up and not.

Your description suggests that there is a mismatch between your /etc/config/wireless and your /etc/config/network

The output of of the following (redacting your IP/MAC addresses if you consider them sensitive) might also be helpful:

ip link                # Which interfaces are known and their state
ip addr                # Assigned addresses
brctl show             # Software bridges established

Thanks @jeffsf for suggesting where to look. There are a lot of entities in my config, so the ‘logs’ below are somewhat long. I am not using the WAN ports as I only have a single ethernet running into my main switch, therefore they are fine to not be up.

I’ll need to go through this on a bigger screen later on, but a couple things caught my eye:

option encryption 'psk2+tkip+ccmp'

First is that allowing TKIP is generally not needed for any reasonably modern client and it reduces the security of your wireless. Second is that it curiously is associated with your troublesome 150 SSID/VLAN. psk2+ccmp would be my recommendation here. That may clear everything up.

config interface 'ifvlan150'
	option proto 'dhcp'
	option type 'bridge'
	option ifname 'eth1.150'

It’s strange to me to have the router’s IP address assigned by DHCP, if it needs one at all. If you’re bridging the wireless clients (and perhaps wired clients) on the VLANs to a network where other services and the default route exist, at least for me, there is no need for the bridge to have an IP address at all. My bridged interfaces used for AP-only functions generally end with

        option proto 'none'
        option auto '1'
        option delegate '0'

delegate is somewhat undocumented, but as I recall it reduces the IPv6 IP assignment. It “works for me” in my applications. Its function can be traced down through /lib/netifd/proto/dhcp.sh

I do have a dedicated management VLAN for my boxes, with a static IP. None of my “in-production” OpenWrt boxes has outside Internet access. If your needs are different, you can chose an approach that suits your security requirements.

option channel 'auto'

This is a placebo. hostapd generally picks the lowest numbered channel and, as far as I know, never budges from it. Picking a channel with reduced interference often gives better results.

	option _orig_ifname 'eth1 ath0 ath1'
	option _orig_bridge 'true'

This is legacy temporary clutter, which can be removed. It was the way that LuCI saved previous settings. This temporary storage has been moved to another location on OpenWrt master, at least. Not a problem, but cleans up your files.
