by

New web-authentication certificate is installed in cisco wireless controllers and this requires to reboot the wireless controllers to take effect. The device will be rebooted on Dec 5 at 9:30am. The users in Soda,Cory and CITRIS will lose wireless connection during the reboot, it should take less than 5 mins for each ap controller to reboot and the services should be restored within a short outage. Since 3 ap controllers will require to be rebooted, the outage will be from 9:30am to 10:00am.

wireless network for EECS-Secure

by

We would switch to use old RADIUS servers due to the certificate issues on new RADIUS servers.

If you have XP and use EECS-Secure, please make sure your configuration on your wireless client is as following link:
https://iris.eecs.berkeley.edu/15-faq/05-windows_2000/xp-eecs-secure.html

If you have vista and use EECS-Secure, please make sure your configuration on your client is as following link:

Other issues, please contact with networks@eecs or help@eecs.

Thanks,

Emergency router reload 5pm

by

The main EECS border router is stuck in a state that prevents either viewing or saving its configuration.

While monitoring the route table during the transition, a command used to examine the hardware routing table status caused the router a fair bit of consternation, leaving it in a state where it is impossible to save or view the configuration.

I will be rebooting the router at 5pm. All external connectivity to EECS will be interrupted, hopefully for a very brief period.

EECS network border upgrade

by

On Monday morning at 7:00-7:45am, I will update the configuration on the EECS border routers to enable BGP peering with campus and bring new 10Gbps links into production.

Subsequently, I will enable direct connectivity between EECS and the Millennium research network at 10Gbps, allowing the research systems to use the 10Gbps uplinks as well.

I have spent considerable time testing the individual changes, and no discernible disruption of connectivity is planned. However given the complexity of the changes, I’m reserving a 45 minute maintenance window.

This work will affect all networks maintained by IRIS, including Soda, Cory, Sutardja Dai, BWRC, & BID, not including AirBears.

This upgrade has been funded in part by the RAD Lab and DETER projects.

Scheduled Campus Wide Air Bears (outage)

by

Description: All control servers and access managers for the AirBears Network are going to receive a software upgrade on Wednesday, October 7, 2009, from 5am to 7am. There will be an initial loss of AirBears network service for the entire campus as the primary and secondary gateways are upgraded. Once the gateways are returned to service, there will be intermittent interruptions of service, from 10 to 20 minutes in length, as the access managers are updated and restored. The entire network should be returned to normal operation by 7:00am.

The only buildings not effected by this outage are Earl Warren Hall (2195 Hearst) and 2484 Shattuck, as they have a different authentication system.

The IST service status page for this incident is http://ucbsystems.org/?s=6399

Campus Wide Emergency Unscheduled Airbears Outage

by

Due to numerous reports of slowness that can be isolated to the primary AirBears gateway device, we will be reconfiguring the network to make the secondary AirBears gateway device the primary. This should not have an impact on authenticated users, but new users will not be able to get a login page during the outage. The anticipated resolution is 12:20pm.

IST will change the network topology for HMMB, starting on Tuesday evening at 6:00 pm. This work is part of the move of the data center from Evans to the new facility in Sutardja Dai Hall. The network in the bldg will be down for approx 12 hours, to allow the fiber contractors to move the cables to the new location.

The following IST subnets will be unavailable during this work:

* HMMB CITRIS 169.229.144.0/25
* Evans-Zone-PPCS-Net
* HMMB1 128.32.120.0/24
* HMMB2 128.32.121.0/24
* HMMB mat lab 128.32.201.192/28
* HMMB Bio Eng 128.32.184.0/25
* AirBears for HMMB


The following EECS subnets will also be unavailable during this work, and again for similar work on Monday, September 21st.
