cookie-size

Configures the size of the cookie field present in each L2TPv3 data packet. L2TPv3 data packets contain a session cookie that identifies the session (pseudowire) corresponding to it. In a tunnel, the cookie is a 4-byte or 8-byte signature shared between the two tunnel endpoints. This signature is configured at both the source and destination routers. If the signature at both ends do not match, the data is dropped. All sessions within a tunnel have the same session cookie size.

Supported in the following platforms:

Access Points — AP310i/e, AP410i/e, AP460i/e, AP560i/h, AP510i/e, AP505i, AP7522, AP7532, AP7562, AP7612, AP7632, AP7662, AP8432, AP8533
