HA A/P Failover - Interfaces not UP



I am some what confused and reaching out for a little help.


We have a pair of 3020s in Active/Passive mode with two interfaces, DMZ (Ethernet1/1) & Public (Ethernet1/3). HA is configured to use dedicated HA Ports and all indicators on the dashboard are Matched and UP.


When I manually suspend the Active device, the Passive device becomes active and the indicators on the dashboard show that the Passive is now the primary (and CLI confirms) but the interfaces remain down. The suspended device interfaces go to a down state. As soon as I enable the suspended device the priority kicks in and the device becomes the Primary again and the interfaces become UP.


Does anyone have an idea?




Group ID: 33
Mode: active-passive


Active/Passive Settings
Passive Link State: shutdown (Active) | Auto (Passive)
Monitor Fail Hold Down Time (min): 1


Election Settings:

Device Priority: 10 (Active) | 110 (Passive)
Preemptive: Yes
Heartbeat Backup: Yes
HA Timer Settings: Recommended


Control Link (HA1): dedicated-ha1
Control Link (HA1 Backup): management
DataLink (HA2): dedicated-ha2 | Transport: Ethernet
DataLink (HA2 Backup): none



Thank you,

hi @SPS 


when you suspend the primary, does the secondary report it is active or non-funct?

are you sure the interfaces are cabled up properly, and the switch ports set up properly (have you tried switching out cables and switch ports and have you verified the switch ports have not been set to a down state)

I thought the passive interfaces were in a down state and displayed red in the PA console but that is only when the device is in a suspended or disconnected state.


I was over thinking things and didn't check the basics! I had put the switch ports into admin down whilst we moved ISPs and forgot to enable them again.


Thank you!


A very embarrassed Scott.
