Vanguard 7300 Functions and Features
Compression
When compressed traffic is sent over a Frame Relay link on the Vanguard 7300
Series, some compressed transmitted frames might corrupt. Vanguard Managed
Solutions recommends that you change the maximum frame size in the Node Record
Configuration from the default of 1620 to 2200. This is the recommended default
whenever compression is activated on a frame relay bypass station on a Vanguard
7300.
