• Key Features of GSM Series SNMP Managed Switches
QoS: These switches offer powerful Quality of Service (QoS) functions. This feature
adds support of TOS fields within the IP packet header (equal DSCP low 3 bits)
on Layer 3 of the network framework and 6 types of network transmission
events on Layer 4. QoS support is important for real-time applications based on
information taken from Layer 2 to Layer 4, such as VoIP.
VLAN: All switch models support Port-based VLAN and IEEE802.1Q Tagged VLAN,
with support for 256 active VLAN's having VLAN ID’s from 1 to 4094. The VLAN
feature in the switch offers the benefits of both security and performance. VLAN
is used to isolate traffic between different users which provides better security.
Limiting the broadcast traffic to within the same VLAN broadcast domain also
enhances performance.
Port Trunking: Allows two or more links to be aggregated together to form a Link Aggregation
Group (LAG). Up to 12 Gigabit ports can be set up per trunk, and a switch can
support up to 8 trunking groups. Port trunks are useful for switch-to-switch
cascading, providing very high full-duplex connection speeds.
Port Mirroring: Port mirroring copies traffic from a specific port to a target port. This
mechanism helps track network errors or abnormal packet transmission
without interrupting the flow of data.
Bandwidth All models support bandwidth allocation rating on a per
Control: port basis. Ingress and egress throughput can be limited to a pre-set
level appropriate to the traffic generally handled on a specific port.
SNMP/RMON:
SNMP is used to remotely monitor and configure SNMP aware devices from a
central SNMP management device, such as SNMP software.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the
SNMP MIB.
All switch models support MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON
MIB (RFC 1757)-statistics Group 1,2,3,9, VLAN MIB (802.1Q, RFC2674),
Ethernet MIB (RFC 1643) and so on.
IGMP Snooping:IGMP Snooping provides a method for intelligent forwarding of multicast
packets within a Layer 2 broadcast domain. By snooping IGMP registration
information, a distribution list of workstations is formed that determines which
end-stations will receive packets with a specific multicast address. All GSM
switches support IGMP version 2 (RFC 2236).
