Vlan Names | Extreme Networks Summit1 guide

VLAN NAMES

—snap — Ethertype inside an IEEE SNAP packet encapsulation.

The values for snap are the same as the values for etype, described previously.

A maximum of seven protocol filters, each containing a maximum of six protocols, can be defined, however no more than seven protocol should be active and configured for use.

For more information on SNAP protocol 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 that are associated with the VLAN.

VLAN NAMES

The Summit supports up to 256 different VLANs. Each VLAN is given a name that can be up to 32 characters. VLAN names can use standard alphanumeric characters. The following characters are not permitted in a VLAN name:

•Space

•Comma

•Quotation mark

VLAN names must begin with an alphabetical letter. Quotation marks can be used to enclose a VLAN name that does not begin with an alphabetical character, or that contains a space, comma, or other special character.
