  • Dynamic MAC address entries can be learned on an interface only after the interface is added to an existing VLAN.
  • Each static MAC address entry can have only one outbound interface.
  • When the aging time of dynamic MAC address entries is set to 0, dynamic MAC address entries do not age. To age MAC address entries, delete the aging time configuration.
  • When MAC address learning is disabled in a VLAN and an interface in the VLAN on the S5700EI, S5710EI, S5700HI, S5710HI, and S5720EI and the discard action is configured for the interface, the interface does not discard packets from this VLAN. For example, MAC address learning is disabled in VLAN 2 but enabled in VLAN 3; Port1 in VLAN 2 and VLAN 3 has MAC address learning disabled and the discard action is defined. In this situation, Port1 discards packets from VLAN 3 but forwards packets from VLAN 2.
  • When the interface frequently alternates between Up and Down, MAC address entries may be not aged within two aging period. At this time, you are advised to check the link quality or run the port link-flap protection enable command to configure link flapping protection.

Meanwhile, plese beware of the adware that might jump in as your device is migrating from one IP to another. The crooks might crack the communication and drop the bug This post was last edited by baryylee at 2018-8-10 23:57.
