13 VLAN overview FIGURE 92 VLAN with dynamic ports-all ports are active when you create the VLAN A = active port C = candidate port When you add ports dynamically, all the ports are added when you add the VLAN. A AAA A AAA SUBNET Ports in a new protocol VLAN that do not receive traffic for the VLAN protocol age out after 10 minutes and become candidate ports. Figure 93 shows what happens if a candidate port receives traffic for the VLAN protocol. FIGURE 93 VLAN with dynamic ports-candidate ports become active again if they receive protocol traffic Ports that time out remain candidates for membership in the VLAN and become active again if they receive traffic for the VLAN's protocol, IP sub-net, IPX network, or AppleTalk cable range. When a candidate port rejoins a VLAN, the timeout for that port becomes 20 minutes. Thus, the port remains an active member of the VLAN even if it does not receive traffic for 20 minutes. After that, the port becomes a candidate port again. A A AA AC AC 440 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
