2 Configure the protocol using the following command:
configure protocol <name> add [etype | llc | snap] <hex> {[etype | llc | snap]
<hex>} ...
Supported protocol types include:
— etype—EtherType.
The values for etype are four-digit hexadecimal numbers taken from a list maintained by the
IEEE. This list can be found at the following URL:
http://standards.ieee.org/regauth/ethertype/index.html
— llc—LLC Service Advertising Protocol (SAP).
The values for llc are four-digit hexadecimal numbers that are created by concatenating a
two-digit LLC Destination SAP (DSAP) and a two-digit LLC Source SAP (SSAP).
— snap—Ethertype inside an IEEE SNAP packet encapsulation.
The values for snap are the same as the values for etype, described previously.
For example:
configure protocol fred add llc feff
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 none. 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.
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
• Comma
• Quotation mark
