Precedence Of Tagged Packets Over Protocol Filters; Vlan Names - Extreme Networks ExtremeWare XOS Guide Manual

2 Configure the protocol using the following command:
configure protocol <name> add [etype | llc | snap] <hex> {[etype | llc | snap]
<hex>} ...
Supported protocol types include:
—EtherType.

configure protocol fred add snap 9999
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.

VLAN Names

Each VLAN is given a name that can be up to 32 characters. VLAN names use standard alphanumeric
characters. The following characters are not permitted in a VLAN name:
Space
