VLAN Relaying
VLAN relaying allows the passage of traffic between the VLANs on one
switch, for protocols that are not processed by the switch’s routing functions.
Particular protocols or protocol groups can be specified, and filtering occurs on
the basis of protocol identification number. VLAN relaying is similar to the
bridging function of an Allied Telesyn router.
Protocol names have been predefined for many protocol types. Those protocols
that are transferred by VLAN relay and that have predefined names are given
in Table 8- 5 on pa ge 8-25, with their associated protocol identification numbers.
Other protocols can be specified by entering their protocol identification
numbers. Protocols that are routed by the switch, including IP, IPX, AppleTalk,
STP, and GARP, cannot be VLAN relayed.
