A Customer needs to transmit UDP Pakets with a MTU/MSS between 1300 and 1400 bytes with SVC v220.127.116.11. Bug ID CSCsg92472 said the current implementation of the Virtual Adapter for SVC has a harcoded MTU/MRU of 1300 bytes. This prevents any larger packets from being successfully received.
This bug tracked a request to have this media MTU/MRU configurable. In the Release Notes of the new SVC 18.104.22.168 the Bug is shown up as fixed Issue: VA media MTU/MRU should be configurable. But where can i adjust it ? Anyone an idea how to fix this ?
Note: Not possible for the moment is the migration to Anyconnect (ASA 8.0), use TCP instead of UDP or manually lowering the MTU size.
