clamp
This option limits the TCP MSS (Maximum Segment
Size) to the size of the MTU (Maximum Transmission Unit) discovered
by path MTU discovery for the inner protocol. This ensures the packet traverses through the
inner protocol without fragmentation. This option is enabled by default.
Supported on the following devices:
- Access Points: AP3000/X, AP5010, AP310i/e, AP410i/e, AP505i, AP510i, AP510e, AP560i, AP6522, AP6562, AP7161, AP7502,
AP7522, AP7532, AP7562, AP7602, AP7612, AP7622, AP763, AP7662, AP8163, AP8543,
AP8533.
- Service Platforms:
NX5500, NX7500, NX9500, NX9600
- Virtual Platforms: CX9000, VX9000
