Creating Inter-Board Port Protection Groups
The inter-board
port protection switching (PPS) is a protection scheme based on ports between
boards. This protection scheme requires an active board and a standby board.
When the active board detects a link down failure of any port, or detects a
board hardware failure, the crossconnect board on the equipment switches the
services of one or more affected ports to the standby board. In this case, a
protection switching of the entire board is not required. Compared with the
board protection switching (BPS), the PPS has less impact on external systems
and the network.
Prerequisites
1 You must be an
NM user with NE operator authority or higher.
2 The Ethernet
boards must be installed in pairs. There must be no services on the protection board.
3 The available
bandwidth of the protection board is higher than or equal to the available
bandwidth of the
working board. In addition, the interface boards must be of the same type
and quantity.
4 The same
EMS4/EGS4 board cannot be configured with BPS and PPS simultaneously.
5 Before
configuring the PPS for the Huawei SDH EMS4 board, you must set the working mode of the
corresponding
interface board such as N1ETF8/N1EFF8 to 100M full-duplex.
Context
When the
following prerequisites are met, the protection group can be switched
automatically.
1 The equipment
that is interconnected with the protection group has the same working mode as
that of the protection group.
2 The transmit
end and the receive end should be connected directly through optical fibers
or network
cables. There should be no equipment between the two ends.
3 The working
mode at the receive end should not be modified before the protection group
is deleted.
Otherwise, the protection group works abnormally.
NOTE
1 After the
inter-board port protection group is created, the protection port cannot be
used to transmit other services.
2 Add all the
ports to the port protection group when you configure an inter-board port
protection group.
3 The N1EMS4,
N1EGS4, and N3EGS4 boards support the inter-board port protection.
4 Configuration
of the intra-board port protection is similar to the configuration of the
inter-board port protection. The difference is that the configuration of the
intra-board port protection is based on different ports on the same board.
Procedure
Step 1 In the NE Explorer, select an NE and choose Configuration > Port
Protection from the Function Tree.
Step 2 Click New and the Create Port Protection Group dialog box is displayed.
Step 3 Enter Protection Group ID, select Working Port and Protection Port.
NOTE
If you directly
click OK without specifying the Protection Group ID, the system automatically
allocates the protection group ID. Click OK in the Warning dialog box.
Step 4 Click OK. A prompt dialog box is displayed, indicating that the
operation is successful.
Step 5 Click Close.
