Data Server Functions

The OfficeServ 7400 provides functions for routing, switching, security, and provides data
network applications and data access interfaces (WAN, LAN, DMZ).

4.2.1 Switches

802.1w Rapid Spanning Tree

Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of the spanning tree and
provides for fast reconfiguration, critical for networks carrying delay-sensitive traffic such
as voice and video. The specification for RSTP is IEEE 802.1w-2001. The RSTP specifica-
tion provides compatibility with legacy STP-based networks.

802.1p Packet Priority

The switch extracts the priority field from the Ethernet frame configured according to the
802.1p specification standard, and discriminatively processes the frame according to the
priority of the specified operation standard.

The packets are categorized into emergent packets and non-emergent packets and are proc-
essed.

VLAN (802.1Q)

The Virtual Local Area Network (VLAN) groups related equipment by work group accord-

ing to the LAN operational policy, regardless of the location of the equipment. The VLAN
also processes switching for work groups. The VLAN removes the effects of unnecessary
broadcasting packets and configures the stable switching subnet only for the corresponding
group by separating and processing the group in the virtual LAN.

Accordingly, the switch can provide the differentiated QoS services and the VLAN can be
configured based on the switch port and MAC address.

The system automatically configures the VLAN for IP phones, signal processing gateway,
media gateway, and UMS required for OfficeServ 7400 services, and performs the QoS
process. OfficeServ 7400 provides 32 VLAN groups.

IGMP Snooping

The L2 switch (located in the lower layer of the IP router) can process IGMP (Internet
Group Management Protocol) messages to allow Multicasting to be used. This is referred
to as IGMP Snooping.

The IP layer multicast group information included in the IGMP message is reflected in the
MAC filtering database, its own switching database. The group information is processed in
the MAC multicast address format mapped with the IP multicast address.
