Nortel Networks 24T manual Predefined Protocol Identifier PID

Using the BayStack 410-24T 10BASE-T Switch

Predefined Protocol Identifier (PID) Description

Table 3-14 defines the standard protocol-based VLANS and PID types that are supported by the BayStack 410-24T switch:

Table 3-14.	Predefined Protocol Identifier (PID)
PID Name		Encapsulation	PID Value (hex)	VLAN Type
Ip Ether2		Ethernet Type 2	0800, 0806	Standard IP on Ethernet Type 2 frames
Ipx 802.3		Ethernet 802.2	FF FF	Novell IPX on Ethernet 802.3 frames
Ipx 802.2		Ethernet 802.2	E0 E0	Novell IPX on Ethernet 802.2 frames
Ipx Snap		Ethernet Snap	8137, 8138	Novell IPX on Ethernet SNAP frames
Ipx Ether2		Ethernet Type 2	8137, 8138	Novell IPX on Ethernet Type 2 frames

		Ethernet Snap		Snap frames
Declat Ether2		Ethernet Type 2	6004	DEC LAT protocol
DecOther Ether2		Ethernet Type 2	6000 - 6003,	Other DEC protocols
			6005 - 6009,
			8038
Sna 802.2		Ethernet 802.2	04 **, ** 04	IBM SNA on IEEE 802.2 frames
Sna Ether2		Ethernet Type 2	80D5	IBM SNA on Ethernet Type 2 frames
NetBios 802.2		Ethernet Type 2	F0 **, ** F0	NetBIOS Protocol
Xns Ether2		Ethernet Type 2	0600, 0807	Xerox XNS
Vines Ether2		Ethernet Type 2	0BAD	Banyan VINES
Ipv6 Ether2		Ethernet Type 2	86DD	IP version 6
User-Defined		Ethernet Type 2,	User-defined	User-defined protocol-based VLAN (see
		Ethernet 802.2, or	16-bit value	“User-Defined Protocol Identifier (PID)
		Ethernet Snap		Description” on page 3-45).
Rarp Ether2		Ethernet Type 2	8035	Reverse Address Resolution Protocol
				(RARP):

RARP is a protocol used by some old diskless devices to obtain IP addresses by providing the MAC layer address. When you create a VLAN based on RARP, you can limit the RARP broadcasts to the ports that lead to the RARP server.
