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.

EECS border route flapping

by

Following IST’s scheduled move of inr-201, the EECS border router experienced frequent route flaps affecting all outbound traffic, resulting in minor packet loss. Pending further investigation, traffic has been diverted to inr-202.

Matlab license renewal

by

IRIS staff have been working for several months to renew EECS department Matlab licenses.

IST is responsible for license agreements with Mathworks and distributes Matlab license to individuals and departments. IST has assured us that our renewal has been processed, and that there is a 30-day “grace period” after the license expires on January 1st.

We understand Matlab is a critical tool for many researchers, and we are doing everything we can to prevent the license from expiring.

morning from 12:00 midnight to possibly as long as 12:00 noon. It will
likely finish before 12:00 noon, but IST reserves the full outage time

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
