Q: What is the range of access-limit configured for sub-interface of MA5200G?
Version: all versions of MA5200G
Symptoms: Set the access-limit of BAS of sub-interface to 1, and the interface has been configured with two VLANs. The users in each VLAN can access network.
1. Set access－limit to 0, and the users under the sub-interface cannot access network, so the setting is effective.
2. Set access-limit to 1, and only one user in each of both VLANs can access network. Therefore, if no specific VLAN parameter is added, it refers to the access-number of VLAN in the interface at peer, not the access number of the whole interface.
The Command Manual explains it as: the access-limit command functions to limit the number of users accessing the VLAN/PVC at BAS. If VLAN/PVC are not specified, the command, the command takes effect for all VLAN/PVC at the BAS interface. By default, access-limit is not configured; in other words, the number of accessed users is 8K. “Effective for all VLAN/PVC at the BAS interface” means the limit is effective for each VLAN/PVC; that is, each VLAN/PVC is set to the number limited by access-limit, not the total added by all VLAN/PVC.
