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.

    Inter-Switch Links.”) Default VLAN The IntraCore 6524 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.
  • Page 102 Advanced Management VLAN Port Membership and Untagging Port members can be added to and deleted from a VLAN Group via the VLAN Management Menu (see “Configuring Static VLAN Groups” on page 4-26). When you add a port to a VLAN, you configure the port to determine its participation in the VLAN.

  • Page 103: Inter-Switch Links

    VLAN Management Inter-Switch Links An inter-switch link (ISL) is a port that connects VLANS that reside on two different switches. An ISL is the means to share VLAN information between switches on a network. For example, consider the two-switch network in Figure 4-6, which connects the Ethernet segments, E-1 through E-9.
