Similar to Run another OS on ASA but with no IDC 16 PIN connector visible on the motherboard I tried to stick a graphics card in an Cisco ASA 5580 to see if I could get the boot screens to get to the BIOS to disable ROMMON as is supposedly possible on some smaller ASA 5500 series models.

Tested on 2024-02-24.

Monitor: Samsung SyncMater 151s with VGA.

Booted with an ASUS EN9400GT PCIe adapter in slot 7.
Result:
Videocard fan does not spin up.
Monitor displays nothing.
ASA 5580 hangs on “Booting system, please wait….”.

Booted with PowerColor Radeon X1650 Pro PCIe adapter in slot 7, with monitor on DVI to VGA adapter.
Result:
Videocard fan does spin up.
Monitor displays nothing. Tried both DVI outputs of the videocard.
ASA 5580 does boot successfully.
‘show inventory’ does not see an extra PCIe adapter.:

I tried booting an ASA 5580 with a Super Micro AOC-STGN-I2S dual-port 10 Gbps Intel X520-based PCIe NIC in either slot 8 or 6, and in both slots it does not work.

The ASA 5580 hangs on “Booting system, please wait….”, and won't continue booting.

Cisco ASA 9.1(7)23 does not have commands to restart/reset a PPPoE connection.

To achieve this with an i

If this is your interface:

MonsterWall-01(config)# show running-config interface gigabitEthernet 3/1
!
interface GigabitEthernet3/1
 nameif outside2
 security-level 0
 pppoe client vpdn group glasnet
 ip address pppoe 

And, for example, your PPPoE connection seems stuck on a 4+ million second uptime (with no seconds being added):

MonsterWall-01(config)# show vpdn session pppoe state


PPPoE Session Information (Total tunnels=1 sessions=1)


SessID TunID Intf State Last Chg
 4695 5 outside2 SESSION_UP 4294967 secs

Reset the PPPoE connection by temporarily removing the 'ip address pppoe' line from gigabitEthernet 3/1:

configure terminal
int gigabitEthernet 3/1
no ip address pppoe
ip address pppoe

Check the PPPoE session, it should now be reset:

MonsterWall-01(config-if)# show vpdn sessio pppoe state


PPPoE Session Information (Total tunnels=1 sessions=1)


SessID TunID Intf State Last Chg
 6106 5 outside2 SESSION_UP 17 secs
