Cisco Bug: CSCur16083 - USD: Mgmt Ethernet Jumbo Frames cause igb/kernel crash
Apr 07, 2015
- Cisco 4000 Series Integrated Services Routers
Known Affected Releases
Symptom: Attempt to use jumbo frames larger than 2k bytes on the management interface GigabitEthernet0 of ISR4000 platforms will result in a system crash. Conditions: Currently, ISR4000 platforms allow jumbo frame configuration on the management interface GigabitEthernet0 of up to 4k bytes. However, the interface does not support jumbo frames, and if the device is configured with an MTU larger than 2k bytes, and packets larger than 2k bytes are sent to the interface, it will result in a system crash. All hardware versions of ISR4000 platforms are impacted by this problem.
