9-14 Configuring VLANs
2. Ports 1 through 5 on the switch unit 4 are configured as egress ports for the VLANs while
ports 8 through 10 on the switch unit 5 are configured as ingress ports that will do the policy
classification.
3. Policy profile number 1 is created that enables PVID override and defines the default behavior
(classify to VLAN 3) if none of the classification rules created for the profile are matched.
4. Classification rules are created for policy profile number 1 that assign IP frames to VLAN 2.
The rules identify IP frames by using the ether protocol parameter, which classifies on the
Type field in the headers of Layer 2 Ethernet II frames, and the protocol data of 0x0800 (IP
type), 0x0806 (ARP type), and 0x8035 (RARP type).
5. Policy profile 1 is assigned to ports ge.5.8 through ge.5.10.

Monitoring VLANs
Table 9-2 describes the show commands that display information about VLAN configurations.
Refer to your device’s CLI documentation for a description of the output of each show command.
Terms and Definitions
Table 9-3 lists terms and definitions used in VLAN configuration.
Table 9-2 Displaying VLAN Information
Task Command
Display all existing VLANs. show vlan
Display the VLAN dynamic egress setting. show vlan dynamicegress [vlan id]
Display all static VLANs. show vlan static
Display ports assigned to VLANs. show port vlan [port-string]
Display existing GVRP settings. show gvrp [port-string]
Table 9-3 VLAN Terms and Definitions
Term Definition
Default VLAN The VLAN to which all ports are assigned upon initialization. The default VLAN has a
VLAN ID of 1 and cannot be deleted or renamed.
Filtering Database A database structure within the switch that keeps track of the associations between
MAC addresses, VLANs, and interface (port) numbers. The Filtering Database is
referred to when a switch makes a forwarding decision on a frame.
Filtering Database
Identifier (FID)
Addressing information that the device learns about a VLAN is stored in the filtering
database assigned to that VLAN. On the fixed switches, each VLAN has its own FID
and FID = VID.
