OS6624/6648 Architecture
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
