246 | Chapter 9. VLANs
NETGEAR 8800 User Manual
A maximum of 15 protocol filters, each containing a maximum of 6 protocols, can be defined.
No more than 7 protocols can be active and configured for use.
Note: For more information on SNAP for Ethernet protocol types, see TR
11802-5:1997 (ISO/IEC) [ANSI/IEEE std. 802.1H, 1997 Edition].
Configuring a VLAN to Use a Protocol Filter
To configure a VLAN to use a protocol filter, use the following command:
configure {vlan} <vlan_name> protocol <protocol_name>
Deleting a Protocol Filter
If a protocol filter is deleted from a VLAN, the VLAN is assigned a protocol filter of any. You
can continue to configure the VLAN. However, no traffic is forwarded to the VLAN until a
protocol is assigned to it.
Precedence of Tagged Packets Over Protocol Filters
If a VLAN is configured to accept tagged packets on a particular port, incoming packets that
match the tag configuration take precedence over any protocol filters associated with the
VLAN.
Default VLAN
The default switch configuration includes one default VLAN that has the following properties:
• The VLAN name is default.
• It contains all the ports on a new or initialized switch.
• The default VLAN is untagged on all ports. It has an internal VLANid of 1; this value is
user-configurable.
VLAN Names
VLAN names must conform to the guidelines listed in Object Names on page 31.
VLAN names can be specified using the tab key for command completion.
VLAN names are locally significant. That is, VLAN names used on one switch are only
meaningful to that switch. If another switch is connected to it, the VLAN names have no
significance to the other switch.
