<strong>iPECS</strong> <strong>SBG</strong>-<strong>1000</strong> <strong>User</strong> <strong>Manual</strong> (DATA Features)<br />

Figure 6.205 <strong>iPECS</strong> <strong>SBG</strong>-<strong>1000</strong> internal architecture<br />

The switch of <strong>iPECS</strong> <strong>SBG</strong>-<strong>1000</strong> has 9 ports including CPU port. The port has a PVID (Port<br />

VLAN ID) and can set VLAN IDs up to 4094 and egress policy. When ingress untagged packets<br />

are received, the PVID is used to handle by default VLAN ID membership.<br />

Figure 6.206 Example of two VLAN configuration<br />

Figure 6.206 is an example of configuration separated by VLAN. The ports 1-4 and CPU have<br />

default PVID 1 and the ports 5-8 have PVID 10. When broadcast packets are input in port 1, the<br />

packets will be forwarded to port 2, 3, 4 and CPU because of same VLAN domain. When the<br />

packets are input in port 8, the packets will be forwarded to port 5, 6 and 7. If the port CPU has<br />

VLAN ID 10 with egress tagged policy, the packets will be transmitted with VLAN header with<br />

VLAN ID 10.<br />

You can find explanations as described in Section 6.4.17.2 for CPU part and Section 6.4.17.4 for<br />

Switch part.<br />
