Admin FAQs and Troubleshooting

b.Telnet or SSH into the active 2.13 system and execute the CLI command reload. Wait until the reload is complete.

c.Telnet or SSH into the standby 2.13 system and execute the CLI command services start.

Symptom Both WLSEs in an HA pair are claiming the same VIP address.

Possible Cause When two devices (for example, device_A and device_B) claim the same IP address, it is possible that some other devices (for example, device_C and device_D) might connect to one of the devices (for example, device_A) while other devices (for example, device_E and device_F) might connect to the other device, device_B, when specifying the IP address claimed by both device_A and device_B.

WLSE uses authentication when each WLSE contacts the other WLSEs, and if the authentication response takes longer than the 15 second timeout, the WLSEs believe the other WLSE appliance is not functioning properly.

In addition, when the AAA server takes longer than 15 seconds, both WLSEs will be in

Active-Lost-Standby status.

Recommended Action When using external AAA service, make sure the AAA server is able to respond to the WLSE in less than 10 seconds. If the AAA server cannot respond to the WLSE in less than 10 seconds, switch the WLSE to use local authentication by selecting Admin > Appliance > Security > Authentication Modules, and choose Local.

Symptom The Device Interaction field is empty when I try to test my Telnet/SSH credentials using the Telnet/SSH Tool under Admin > Appliance > Connectivity Tools.

Possible Cause Another user using the Telnet/SSH tool page simultaneously can cause the Device Interaction field to be empty.

Recommended Action Wait a few seconds and try using the Telnet/SSH Tool again.
