Wireless Access

Hello,

our customer with Aruba AP 515, asked to connect it with two Eth, to obtain more capacity.

We connectet it to an Aruba 6000 switch. The switch port has been configured in lag, with lacp-mode active. Then we passed the vlan into the lag interface.

When the AP is connected with two cables, we can see from the switch and also from AP serial interface, that the LAG is working correctly at 2 Gb.

Access points look working correctly, but when only some clients are able to connect, while other present problems to obtain an ip address, from the custom firewall.

If we connect the AP to the LAG with only one cable, there aren't problems, all clients can connect correctlly and obtain immediatly an IP address.

The AP is always connected to the LAG, but the issue is present only when it is connected with two cables.

Some idea of what could be the problem? Am I missing something in my configuration?

Thanks!

Kind regards.

Hi DB86,

I know that document, but it didn't help.

I have to add that the AP are managed in Instant mode.

Thank you.

Enabling Static LACP Configuration

When Instant APs connect to switches which have the LACP capability, the LACP feature does not work as expected. To enable a static LACP configuration, new commands are introduced.

Instant APs support the dynamic LACP configuration according to a peer switch. When the peer switch enables LACP configuration, the Instant APs form the LACP. Users can enable, disable, and remove the static LACP configuration in the Instant AP. When the Instant AP boots up, it forms the LACP according to the static configuration.

To enable the static LACP mode on Instant APs:

(Instant AP)# lacp-mode enable

To disable the static LACP mode on Instant APs:

(Instant AP)# lacp-mode disable

Verifying Static LACP Mode

To verify the static LACP configuration, execute the following command in the Instant AP CLI:

(Instant AP)# show ap-env

Antenna Type:Internal

name:TechPubsAP

per_ap_ssid:1234

per_ap_vlan:abc

lacp_mode:enable

Yes, I tested both the possibilities, static and dynamic lacp, but with the same results and problem.

In my case the lacp was correctly formed in both cases, but wireless network was working fine only when the APs were connected with only one cable.

What benefit are you expecting to obtain from utilizing a LAG that isn't also available through active/standby connectivity?  Unless you are testing under lab conditions you will likely never reach a wireless throughput that would saturate a single 1 Gbps connection.

Yes, I tested both the possibilities, static and dynamic lacp, but with the same results and problem.

In my case the lacp was correctly formed in both cases, but wireless network was working fine only when the APs were connected with only one cable.

Hello Carson,

customer bought the APs from a network "consultant", than asked us to configure it, following the consultant request. So he expect to see a 2Gb Lag and the wifi working.

Also because in the AP datasheet there is this sentence " Link aggregation (LACP) support between both network ports for redundancy and increased capacity".

Why Aruba affirms that in the datasheet, if  as you said "it isn't available through active/standby connectivity"?

Thanks!

If you will re-read my reply you'll notice that what I asked was "What benefit are you expecting to obtain from utilizing a LAG that isn't also available through active/standby connectivity?"  Nothing about that says we don't support LACP.

Why do you affirm that   "you will never reach a wireless throughput that would saturate a single 1 Gbps connection"?
If I aggregate all the wifi clients traffic, couldn't it be superior to 1Gbps, if the uplink allow it?

If you will re-read my reply you'll notice that what I asked was "What benefit are you expecting to obtain from utilizing a LAG that isn't also available through active/standby connectivity?"  Nothing about that says we don't support LACP.
