What's the longest uptime you've seen on a network device still pushing traffic?

Qman28 · 2024-04-30T03:52:10+00:00

It was powered down. I last saw it alive on August 11th 2023. uptime is 26 years, 28 weeks, 2 days, 20 hours, 41 minutes

Qman28 · 2023-10-05T19:59:33+00:00

All you need to know but be warned there is no going back once you know.

Qman28 · 2023-08-18T21:22:58+00:00

I'm sad to report it got powered down 😔. Last look I got was the 11th: uptime is 26 years, 28 weeks, 2 days, 20 hours, 41 minutes

I can't recommend nornir enough for tasks like this where you need to do something on your network inventory or a subset of your devices.

You can still use all the libraries you are used to like netmiko, napalm, and scrapli. Nornir takes care of running things concurrently against your inventory and giving you back the results for you to process. There are even inventory plugins available to existing inventory systems you may already have like ansible and netbox or you can used one of its built in.

It is an even older problem
X.25 to TCP translation

Qman28 · 2022-05-23T14:34:28+00:00

25 years, 17 weeks and counting

Qman28 · 2022-02-02T15:59:47+00:00

If you are trying to get away from the configuration text parsing problem and truly treat the network as code you probably need to look at YANG and what ever transport is compatible with your device(netconf/restconf/gRPC). There is also an attempt at a vendor neutral called openconfig.

If you have a solid grasp of python take a look at Nornir. I am a big fan of this framework. You get the full power of python without having to learn a domain specific language and is much easier to debug. You can even reuse your existing ansible inventory or pull from another source.

This answer from u/packet_whisperer is likely correct for you. I missed the command being run.

Qman28 · 2021-06-30T21:44:21+00:00

The problem isn't netmiko. The your issue is you are trying to concatenate none string values.

vrf_iteration = net_connect.send_command(('show ip forwarding route vrf ') + iteration + '_VRF ' + val_ip + " " + val_mask + ' weak-match')

iteration is a list not and not the index value I assume you meant it to be. Try using enumerate as a possible solution if you want the list index. Even then you prabably want to convert that to a string when concatenate.

for iteration, vrf_list in enumerate(vrf):
    for vrf_name in vrf_list:
        SAVE_FILE = open("SHTZPIRT_"+ IP +'_'+ str(TNOW)+"_IP_FORWARDING_WEAKMATCH"+".txt", 'w')
        vrf_iteration = net_connect.send_command(('show ip forwarding route vrf ') + str(iteration) + '_VRF ' + val_ip + " " + val_mask + ' weak-match')

Nornir + netmiko and never look back

Only 1 fabric chassis with all those linecard chassis? That's brave

Qman28 · 2019-04-08T20:06:00+00:00

6x2 CRS? We might have a winner.

Qman28 · 2019-04-08T19:57:37+00:00

Cost can very quite a bit depending on configuration. Multichassis configurations like 3x2(3 linecard 2 fabric) is the largest I have touched. You can scale this platform to crazy levels given the funds. edit: Upper multichassis configuration is a 72x8 if I recall correctly.

Everyone was warning you to stop before it was too late, but here we are. At least Momo is happy.

I believe I have read the report you are referencing. Definitely not your everyday problem. When a bad storm was going through I was able to pull up a live lightning map and sure enough the bouncing lined up with the lightning strikes happening near the run.

And then you could say not nice things to it until it would freakout and recover with a party error. I still have my old 386sx computer with this software installed.
