If the maximum age timer expires before the bridge receives another BPDU, it assumes that a change in the topology has occurred, and it begins recalculating the spanning tree.

    Advanced Management A VLAN localizes flooded traffic to parts of LAN segments rather than to a whole LAN. VLANs offer a simple and efficient solution that enhances network performance, bandwidth utilization, and network security by localizing flooded traffic. Port-based VLANs are the simplest of many VLAN approaches that solve the problem of unnecessary flooding.

    “Configuring Inter-Switch Links.”) Default VLAN The IntraCore 8000 is configured by default with a single VLAN, with VID = 1; by default, all ports on the switch are assigned to VLAN 1. By default, the ports are also in the VLAN’s untagged set, which means they send only untagged frames.

    Advanced Management Port members can be added to and deleted from a VLAN Group via the VLAN Management Menu (see “Configuring Static VLAN Groups”). When you add it to a VLAN, you configure a port to determine its participation in the VLAN.

    VLAN Management By default, independent learning of addresses is enabled. Under independent learning, all addresses learned in a VLAN are stored in an address table for that VLAN only, and all forwarding decisions for that VLAN are made by consulting that table. This can sometimes cause unexpected results if a port is a member of more than one VLAN.
