Description of the problem
The network element is configured with four OSN3500 N1EFS0 boards, and the other three single boards are configured with more than 1,000 VLAN pass-through services, but when the fourth board is configured, only 300 items are configured, and then when configured again, it prompts "the database is full", and the service cannot be configured again.
Process
1. Query the 4 N1EFS0 single boards with the same version, so it should not be that the cache of this single board only supports more than 300 entries;
2, let the user in the fourth EFS board to delete the board a VLAN service, and then pass through the VLAN has not been configured, the configuration is successful; delete this service, configure just could not be configured to go down the VLAN, but also successful; continue to configure the other VLAN services, the same prompts the database is full;
3, the first three EFS0 any piece of business to delete a, and then configured to the fourth EFS0 success. Initial judgment should be the equipment on the number of pass-through VLAN service has a limit;
4. Confirm with R&D that the number of OSN3500 hosts on VLAN passthrough is not unrestricted, but is restricted to 8192 unidirectional entries and 4096 bidirectional entries. The user confirms that the total number of VLAN pass-throughs configured on the four N1EFS0 boards of the network element has exceeded 4,000, so it is not possible to continue to configure them, and the prompt is "database is full".
Root Cause
The OSN3500 host has a limitation on the number of VLAN passthroughs, instead limiting it to 8192 unidirectional entries and 4096 bidirectional entries.
Solution
Increase network elements or reduce unnecessary operations.
