Laggish connection after power outage

vladimir_buzuev — Thu, 11 Mar 2021 23:02:27 GMT

Hello,

Hope somebody can help me to understand and fix the problem below, thanks.

Setup (Lennar home): R510 + ICX7150-C12 + AT&T Router (with Fiber broadband)

R510 is connected to the Switch's port 11 and is PoE,

Router is connected to Switch's port 12

Router provides DHCP + DNS

Everything worked OK before yesterday's power outage. Now the connection is very laggish. I mean, it seems it takes up to several seconds to establish a connection to (any) site, but after it is established the speed seems to be as usual. Broadband itself not local clients are is an issue, as if connected directly to router's Ethernet (or router's WiFi) all work OK.

Another problem is that in Unleashed UI the switch shown as disconnected, similar to https://forums.ruckuswireless.com/conversations/ruckus-unleashed/ruckus-switch-unreachabledisconnected-after-power-outage/5f91c401135b77e247915a2c

and the weirdest thing: depending on what Wi-Fi the client device is connected to, either R510 or Switch are not reachable. If I connect to R510 Wi-Fi, Switch can't be reached; if I connect to the router's Wi-Fi, R510 can't reached.

R510 and Switch seem to see each other at LLDP:

SSH@ICX7150-C12 Router>show lldp neighbors

but R510 can't ping Switch

https://forums.ruckuswireless.com/conversations/ruckus-at-home/power-failure-causes-switch-to-reboot-into-router-mode/604a226f56830c0d5879b43c says that Switch might be in a wrong mode, how do I check that?

Any other steps can be done to troubleshoot?

Thanks!!!

So, I tried to reboot the Switch using primary flash using

boot system flash primary yes

but it failed and used the secondary one. And it seems it IS in router mode at least based on the device name:

So, any idea how to put it back to 'switch' mode? Thanks.

So, I see that Switch has "switch" mode primary flash, and "router" for the secondary:

SSH@ICX7150-C12 Router>show flash
Stack unit 1:
NAND Type: Micron NAND 2GiB (x 1)
Compressed Pri Code size = 28660224, Version:08.0.90dT211 (SPS08090d.bin)
Compressed Sec Code size = 32539748, Version:08.0.90dT213 (SPR08090d.bin)

So, how to troubleshoot the reason why it did fail to boot using primary flash?

Well, had to reflash both primary and secondary flash with switch flash, works OK now...

Hi Vladimir,

Please open a support case for ICX and support should be able to help you.

If you have logs, they may be able to check the failure reason, but if logs are gone, they may also not able to provide more insights.
