It's worth mentioning that's it's not limited to just the cosmetic issue of interface counters/snmp counters. - I've had multiple instances of 920 interfaces getting stuck in their previous operational state. Unplugging-replugging/shut/no-shut doesn't change anything. - The 920 fails to process traffic towards very specific IPs. That one is a pain to debug. You can reach the IP directly from the device but flows through the device are just dropped (also saw the same behavior on 903 with RSP3) - ARP under a BDI show up and are re-learned after a clear but traffic towards those IP do not work through or sourced from the 920. - One 920 started to show the above described symptoms, was rebooted and failed to back up. ISIS went up, cannot ping any of the P2P. That said, uptime should definitely be monitored through your central NMS-flavor system. ;) On Fri, Jan 25, 2019 at 7:45 PM Erik Sundberg <ESundberg () nitelusa com> wrote:
It was a script I created in regards to this thread below... Interface counters and some other things stop working after a Cisco ASR920 is up 889 days....

Thanks! So you want a warning if a router hasn’t been rebooted in a long time? Just out of curiosity, why? I’m kind of glad that my routers don’t reboot, pretty much ever. Usually I want to know if the uptime suddenly became less than the most recent uptime, indicting a possibly unplanned reboot. -melOn Jan 25, 2019, at 4:29 PM, Erik Sundberg <ESundberg () nitelusa com>wrote:All, I just created a quick script to check the uptime of a ASR920 via SNMP if you have a fairly long list of devices. It's a simple bash script and snmpwalk version 2c. Figured I would share it with you. Happy Friday Grab the code from GitHub: https://github.com/esundberg/CiscoRouterUptime It's a quick and dirty script and my first repo on github. Let me knowif there any issues with it.Output Format in CSV DeviceName, IP, Uptime in Days, OK/Warning I set my warning to 800 Days, you can change this in the code ASR920list.txt ------------- ASR920-1.SEA1, 192.168.28.1, SuperSecretSNMPKey ASR920-2.SEA1, 192.168.28.2, SuperSecretSNMPKey ~~~~snip you get the idea~~~~ Output [user@Linux]$ ./CiscoRouterUptime.sh ASR920list.txt ASR920-1.SEA1, 192.168.28.1, 827, WARNING ASR920-2.SEA1, 192.168.28.2, 827, WARNING ASR920-2.ATL1, 192.168.23.2, 828, WARNING ASR920-1.ATL1, 192.168.23.1, 813, WARNING ASR920-1.CHI1, 192.168.21.3, 828, WARNING ASR920-1.NYC1, 192.168.25.1, 787, OK ASR920-2.CHI1, 192.168.21.4, 720, OK ASR920-3.CHI1, 192.168.21.5, 720, OK ASR920-1.DAL1, 192.168.26.3, 488, OK ASR920-4.CHI1, 192.168.21.6, 142, OK ________________________________ CONFIDENTIALITY NOTICE: This e-mail transmission, and any documents,files or previous e-mail messages attached to it may contain confidential information that is legally privileged.
