OmniSwitch 6XXX is a stackable version of the OS7/8XXX Switches. It provides pure Ethernet switch-
ing for 10/100 and Gigabit ports, along with stackability.

The key features of OmniSwitch 6XXX are:

• ELEMENT - One Standalone HAWK Unit (1 or 2 Intel Devices)

• Module - Insertable modules (Gigabit copper, fiber, or stackable)

• SLOT - Software numbering of an element

• Virtual Chassis - a stack of Hawk units (max stack =8)

• GARP - Generic Attributes Registration Protocol - A generalized protocol, defined in IEEE802.1p, for 

signaling between workstations and the network.

• GMRP - GARP Multicast Registration Protocol - a version of GARP, which allows devices to request 

membership in a specific multicast group. Part of the IEEE802.1Q/P, cited by Alcatel Enterprise QOS 
requirements.

• GVRP - GARP VLAN Registration Protocol - a version of GARP, which allows devices to request 

membership in a specific virtual LAN.

• IGMP - Internet Group Management Protocol, Version 2. The Hawk “snoops” this protocol to deter-

mine which ports should receive copies of multicast packets.

• IP Multicast - data packets sent from an IP host and intended for reception by a number of IP destina-

tion hosts. IP multicast frames have a Class D address in the 224.0.0.0 to 224.255.255.255 range. Each 
address refers to an individual “broadcast stream” rather than a destination host. IP multicast was origi-
nally implemented using Ethernet multicast MAC addresses and was received by all hosts on the LAN.

• SFP - Small Form Factor Pluggable - Small form factor Fiber Gigabit connectors.

• Group Mobility - Alcatel Proprietary Protocol based VLAN

• Spanning Tree- Both 802.1D and 802.1W

• QOS

• Routing- Local, Static, RIP (2) and OSPF

• Link Aggregation

• 802.1Q

• Authenticated VLANs

• UDP/Bootp Relay

• Redundant Management when stacked
