Hi All, I just installed a secondary firewall in act/standby setup and noticed that it seems to be overheating. See the output of show env command below. It seems that the CPU is at 75* but the Chassis fan is just at 2600rpm. And this is on a firewall that just sits there in standby, 0% cpu usage.   On my other firewalls (that are actually doing stuff) the chassis fan is at ~4000rpm with 30* cpu temperature.       Cooling Fans: -----------------------------------    Chassis Fans:    --------------------------------    Chassis Fan: 2640 RPM - OK Temperature: -----------------------------------    Processors:    --------------------------------    Processor 1: 75.0 C - Critical  (CPU Core Temperature)    Accelerators:    --------------------------------    Accelerator 1: 40.0 C - OK  (Accelerator Temperature)    Chassis:    --------------------------------    Ambient 1: 40.0 C - OK  (Chassis Temperature)    Motherboard:    --------------------------------    Ambient: 40.0 C - OK  (Chassis Temperature) Voltage: -----------------------------------    Channel 1: 12.364 V - OK  (12V)    Channel 2: 5.000 V - OK  (5V)    Channel 3: 1.351 V - OK  (1.35V_CPU)    Channel 4: 0.982 V - OK  (1.0V_VCC)    Channel 5: 1.017 V - OK  (1.0V_VNN)    Channel 6: 1.802 V - OK  (1.8V_CPU)    Channel 7: 1.071 V - OK  (1.07V_CPU)    Channel 8: 0.849 V - OK  (0.85V)    Channel 9: 3.344 V - OK  (3.3V)    Channel 10: 2.531 V - OK  (2.5V)    Channel 11: 1.510 V - OK  (1.5V)    Channel 12: 1.217 V - OK  (1.2V)    Channel 13: 0.899 V - OK  (0.9V)    Channel 14: 1.355 V - OK  (1.35V_DDR)    Channel 15: 3.347 V - OK  (3.3V_STBY) ALARM CONTACT 1     Status:      not asserted     Description: external alarm contact 1     Severity:    minor     Trigger:     closed ALARM CONTACT 2     Status:      not asserted     Description: external alarm contact 2     Severity:    minor     Trigger:     closed Driver Information: -------------------- Status : RUNNING     ---   Cisco Adaptive Security Appliance Software Version 9.8(2)17 Firepower Extensible Operating System Version 2.2(2.63) Device Manager Version 7.9(1) Compiled on Thu 04-Jan-18 10:21 PST by builders System image file is "disk0:/asa982-17-lfbff-k8.SPA" Config file at boot was "startup-config" DBFirewall up 3 hours 11 mins failover cluster up 19 days 1 hour Hardware:   ASA5516, 8192 MB RAM, CPU Atom C2000 series 2416 MHz, 1 CPU (8 cores) Internal ATA Compact Flash, 8000MB BIOS Flash M25P64 @ 0xfed01000, 16384KB ...

Hi Guys, I have a core switch (3750-x stack) connected to an access switch (3560x) with a 10GB fiber link. I also have a backup 4x1GB port channel. The problem is that I can make the 10G link work, but it just turns off after a few hours without a clear reason, and then I have to shut the port down and turn it back on on the 3750-x side to make it work again for a few hours. This is the best case scenario, last week I had to remove config from both ports and reconfigure them again to make the link work.   Here is the config on 3750-x: interface TenGigabitEthernet2/1/2  switchport trunk allowed vlan 91,101,102  switchport trunk encapsulation dot1q  switchport trunk native vlan 999  switchport mode trunk  udld port aggressive  spanning-tree portfast network end   And on 3560-x: interface TenGigabitEthernet1/1  switchport trunk allowed vlan 91,101,102  switchport trunk encapsulation dot1q  switchport trunk native vlan 999  switchport mode trunk  udld port aggressive  spanning-tree portfast network end   The ports are not in err-disabled state, and there are no errors: TenGigabitEthernet2/1/2 is down, line protocol is down (notconnect)   Hardware is Ten Gigabit Ethernet, address is a46c.2aab.35b6 (bia a46c.2aab.35b6)   Description: connected to DBAMSSW03   MTU 9126 bytes, BW 10000000 Kbit/sec, DLY 10 usec,      reliability 255/255, txload 1/255, rxload 1/255   Encapsulation ARPA, loopback not set   Keepalive not set   Full-duplex, 10Gb/s, link type is auto, media type is SFP-10GBase-SR   input flow-control is off, output flow-control is unsupported   ARP type: ARPA, ARP Timeout 04:00:00   Last input 3d14h, output 3d14h, output hang never   Last clearing of "show interface" counters 4d15h   Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0   Queueing strategy: fifo   Output queue: 0/40 (size/max)   5 minute input rate 0 bits/sec, 0 packets/sec   5 minute output rate 0 bits/sec, 0 packets/sec      535657539 packets input, 990801863713 bytes, 0 no buffer      Received 374735 broadcasts (322986 multicasts)      0 runts, 0 giants, 0 throttles      0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored      0 watchdog, 322986 multicast, 0 pause input      0 input packets with dribble condition detected      485084056 packets output, 643747320202 bytes, 0 underruns      0 output errors, 0 collisions, 0 interface resets      0 unknown protocol drops      0 babbles, 0 late collision, 0 deferred      0 lost carrier, 0 no carrier, 0 pause output      0 output buffer failures, 0 output buffers swapped out     TenGigabitEthernet1/1 is down, line protocol is down (notconnect)   Hardware is Ten Gigabit Ethernet, address is 44d3.ca1e.e7b5 (bia 44d3.ca1e.e7b5)   Description: connected to DBAMSSW01   MTU 9126 bytes, BW 10000000 Kbit/sec, DLY 10 usec,      reliability 255/255, txload 1/255, rxload 1/255   Encapsulation ARPA, loopback not set   Keepalive not set   Full-duplex, 10Gb/s, link type is auto, media type is SFP-10GBase-SR   input flow-control is off, output flow-control is unsupported   ARP type: ARPA, ARP Timeout 04:00:00   Last input 3d14h, output 3d14h, output hang never   Last clearing of "show interface" counters 2w6d   Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0   Queueing strategy: fifo   Output queue: 0/40 (size/max)   5 minute input rate 0 bits/sec, 0 packets/sec   5 minute output rate 0 bits/sec, 0 packets/sec      805079008 packets input, 1006982654176 bytes, 0 no buffer      Received 2978817 broadcasts (967136 multicasts)      0 runts, 0 giants, 0 throttles      0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored      0 watchdog, 967136 multicast, 0 pause input      0 input packets with dribble condition detected      955498446 packets output, 1702746280144 bytes, 0 underruns      0 output errors, 0 collisions, 8 interface resets      0 unknown protocol drops      0 babbles, 0 late collision, 0 deferred      0 lost carrier, 0 no carrier, 0 pause output      0 output buffer failures, 0 output buffers swapped out   I have the same exact setup going to the other access switch and it works fine. I can think of a few things to troubleshoot (change the SFP modules + cable from the other switch), but I was wondering if you have any idea what else I could check / debug to see why the problem is happening?   Thanks, Jakub ...
