A hybrid interface can connect to either a user host or a switch, and it can connect to an access link or a trunk link.
A hybrid interface permits frames from multiple VLANs to pass and can remove VLAN tags of outgoing frames.
OLP can be classified into OTS OLP protection and OMS OLP protection. Whether TN11OLP01 or TN12OLP01 boards can be used to form OLP depends on the input optical power values of optical ports RI1 and RI2 on OLP boards.
If the input optical power values of both optical ports RI1 and RI2 on OLP boards do not exceed 7 dBm, TN11OLP01 or TN12OLP01 boards can be used to form OTS OLP protection.
In the OMS OLP protection scenario, the input optical power values of optical ports RI1 and RI2 are prone to exceed the maximum optical power (+7 dBm) of the TN11OLP01 and TN11OLP02 boards. Therefore, TN11OLP01 or TN12OLP01 boards cannot be used in this scenario.
1. An RDD compatible with Hadoop can be created from the Hadoop file system or other storage systems that are compatible with Hadoop. HDFS is an example.
2. A new RDD can be converted from a parent RDD.
3. An RDD can be converted from a collection.
