|Ticket Description:||Excessive CPU load on router swiMA2 in Manno|
Problem Description:The router swiMA2 in Manno is responding slowly due to excessive CPU load since about 1 am on Nov 5, 2011. The reason is unknown at this moment. While response to control traffic is erratic, we expect normal traffic to be forwarded with little impact.
Affected:From 2011-11-05 01:00 until 2011-11-05 12:00
Impact: no impact
Service: network access
Sites: CSCS, TI-EDU
The cause was tracked down to a malfunctioning ERSPAN (remote port-mirroring) session internal to SWITCH. The CPU load on swiMA2 returned to normal after removing the faulty sesson.
