This port parameter instructs any media module connected to a secure network
to expect a security message transmission from the Ethernet Private Line Card
for each transmitted packet. This message provides information on whether or
not the module should jam a transmitted packet.

After security is configured, do not disable security on a network that has
per-port failsafe enabled, or switch a secure port to an unsecured network.
Disabling security or switching the port to an unsecured network causes the
