Service Management

This chapter describes service management for the switch. The Web system provides management functions for VLAN, MAC, STP, Voice VLAN, DHCP, ARP, VRRP, and IGMP Snooping services. You can query and configure the required services.

VLAN
The following sections describe how to configure and query VLANs, hybrid interfaces, access interfaces, trunk interfaces, and VLANIF interfaces.
MAC
Each switch maintains a MAC address table (MAC table for short). The MAC table records MAC addresses of all the devices connected to interfaces of the switch. When forwarding a data frame, the switch searches the MAC table for the outbound interface according to the destination MAC address of the frame. This reduces the number of broadcast frames.
STP
The following sections describe how to query the STP information and set the global STP parameters, STP parameters on an interface, and parameters of an MST region.
Voice VLAN
A voice VLAN is assigned to voice data flows. You can create a voice VLAN and add the interface connected to a voice device to the voice VLAN. Then voice data flows can be transmitted on the voice VLAN.
DHCP
The switch supports Dynamic Host Configuration Protocol (DHCP) applications based on the global address pool or an address pool configured on a VLANIF interface. The switch also provides security guarantee for DHCP services and supports DHCP relay. The S5700LI switches do not support the function.
ARP
The following sections describe configurations of static ARP and dynamic ARP.
VRRP
The following sections describe configurations of VRRP groups and VRRP parameters. The S2750, S5700LI, S5700SI and S5700S-LI switches do not support the VRRP function.
IGMP Snooping
The following sections describe configurations of IGMP snooping on a switch.
