PORT FAILSAFE
Use the SET SECURITY_ADVANCED PORT FAILSAFE command to require security
message transmissions on an Ethernet network that has an Ethernet Private Line
Card assigned to it.
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.
If, however, a security message for a packet is not transmitted to the media
module, and per-port jamming as well as failsafe are enabled, the media
module automatically jams all outgoing packets.
You must enable both failsafe and per-port jamming for the failsafe feature to
function. Do not enable failsafe on a port until that port is operational and the
appropriate security port and network parameters are set.
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
failsafe port parameter to jam all transmitted packets destined for the port.
Format
Example
The following command enables failsafe on port 5.1:
CB5000> set security_advanced port 5.1 failsafe enable
Port 05.01 failsafe set to ENABLED.
