For example:

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].
Deleting a Protocol Filter
If a protocol filter is deleted from a VLAN, the VLAN is assigned a protocol filter of
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 switch ships with one default VLAN that has the following properties:
The VLAN name is default.
●
It contains all the ports on a new or initialized switch.
