Introduction : This article outlines the procedure to configure two ethernet uplinks for an Aruba Instant Cluster.
Feature Notes :
Following are the feature notes ::
Environment : Aruba Instant cluster with two different uplink paths connected to eth0 & eth1 of the APs.
Network Topology :
Configuration Steps : With ports plugged into appropriate switches with proper VLAN configuration; below is the configuration needed on IAP end.
Create a new Wired Port Profile

Ensure "Uplink" option is enabled

Configure appropriate VLAN to match switch config.

Save and map the profile to the port.

Set appropriate proirity and failover time under "System --> Uplink".

Answer : With the configuration in place; the AP would be switchover to alternate uplink in case of failure.

Verification :
Troubleshooting :
Below are the troubleshooting steps for issues related to dual uplink .
-
Ensure link status; using "show uplink status". If the link isn't up; then focus on troubleshooting link not coming up
-
If "internet failover: is enabled; ensure internet connectivity is available else link would flap over to the alternate uplink
-
If "internet failover" is enabled and config for ICMP check is aggressive; it may result uplink switchover when uplink has performance issues.
-
"show log system" would show information on link switching.
