130.129.152.1 Host is down

[daigle@…]

Hi,

I'm in room 1177 (waaaaaaay at the end of the hallway in the West Wing) 
and v4 connectivity seems to have evaporated.

Looks like v4 isn't routing:

bash-3.2$ ping 130.129.152.1
PING 130.129.152.1 (130.129.152.1): 56 data bytes

Leslie,

We're seeing about 60Mbps of traffic going through that interface right now, so it's unlikely to be completely down. Can you tell if you're still seeing good wireless link? It's possible that one of the APs got sick, but also that if you're at the end of the hall that you may just have RF/Wireless side issues.

Hi,

I still show strong wireless signal.   I'm  willing to not rule out that it's my machine, but it's freshly rebooted and running the latest version of mavericks, so I'm not sure why it would be (persistently) confused?

Leslie.

Hi again,

FYI -- a couple updates:

1/ This is a transient problem.  I thought things were fine this morning... until they weren't.

2/ I don't have the issue on the hotel wireless natwork (same AP, same protocol (v4), different routing) with no issue.

Leslie.

Leslie,

Last night we had a IPv4 DHCP pool exhaustion ... we guessed wrong on the number of associations, and we increased the size of the network & associated pools. Are the problems still happening today?

Hi Jim,

The problems were still happening this morning (when I sent the note about the hotel natwork working for my computer).

At Lucy's suggestion, I did the "forget networks" thing to have a fresh start with the DHCP server -- too early to tell if it is working consistently or not (but it is, at the minute).

Thanks,
Leslie.

Good morning, Leslie,

As Jim mentioned, we identified and resolved an issue with DHCP a few nights ago. Last night we identified and resolved a VRRP configuration issue that may have also been contributing to your connectivity problems. If you have a free minute and you are in your room, would you mind checking reachability to 130.129.152.1?

Thank you very much!

Hi,

Reachability now looks good -- thanks!

Leslie.

Terrific! I'm guessing you're problem was caused by the VRRP configuration issue. I'm going to close this ticket and thank you for your patience.
