SecureStacks/G-Series do not support Routing of Jumbo Frames


Userlevel 3
Article ID: 11750

Products
SecureStack C3, C2, B3
G-Series

Symptoms
Jumbo frames are being fragmented when routed.

Cause
The routing of jumbo frames is not supported on these products, because it is not possible to change the MTU size (1500) on a routed interface.

If switch ports are configured to receive jumbo frames (by default, 'set port jumbo enable' is in effect) and those frames are routed between VLANs, the frames will be fragmented for routing and must be reassembled when received at the final destination.
