Problem Description.
The physical veneer of SSN3EFS4 is configured as a logical veneer type of N1EFS4 using the multi-board ID function. On a certain day, the customer needs to enable the LCAS function, the host version is 5.21.16.13, the network management version is V2R4C01, and the latest patch has been applied, but the maintenance interface of LCAS cannot be seen.
Alert messageNone
Processing1. For the case that the logical board type of NGSDH V100R006 is configured as N1EFS4 and N2EFS0 (including the case that the physical board type itself is N1EFS4 and N2EFS0, or that the physical board type is N2EFS4 and N4EFS0, but the logical board type is configured as N1EFS4 and N2EFS0), the interface of LCAS V2.0 supported by the single board remains the same. LCAS V1.0 interface, and the network management defaults to close the LCAS V1.0 interface, which needs to be opened by the following steps:
Load the network management V2R4C01B01CSPC002 patch;
2. Modify the ems.cfg configuration item, in the ems.cfg file: "#@ LCASV1 Feature Switch ", 0 means that the network management does not support LCAS features, 1 means that the network management supports LCAS features (# LCASV1 switch. 0: unsupport, 1: support), here modify "LCAS = 1" can be.
After modification, you need to restart Server/Client.
3. For NGSDH V100R006 and OSN 9500 V100R004 or above, the network administrator provides LCAS V2.0 configuration interface and auxiliary functions
Load the network management V2R4C01B01CSPC002 patch;
2. Modify the ems.cfg configuration item, in the ems.cfg file: "#@ LCASV1 Feature Switch ", 0 means that the network management does not support LCAS features, 1 means that the network management supports LCAS features (# LCASV1 switch. 0: unsupport, 1: support), here modify "LCAS = 1" can be.
After modification, you need to restart Server/Client.
3. For NGSDH V100R006 and OSN 9500 V100R004 or above, the network administrator provides LCAS V2.0 configuration interface and auxiliary functions
Root CauseSuspected that the network management did not open the LCAS function, check the network management situation, found that LCAS2.0 has been turned on by default, and check the LCAS2.0 topic found that the interface of LCAS V2.0 supported by the N1EFS4 and N2EFS0 single boards is still the interface of LCAS V1.0, while the network management is turned off by default the interface of LCAS V1.0.
