Port mirroring
A copy of ingress and egress data of the
monitored port is sent to snooping port
Scalability Trunking (Static Link Aggregation)
Increase bandwidth and redundancy.
Up to 8 ports per trunk, 4 trunks per switch.
Redundancy
IEEE802.1D STP
IEEE802.1W RSTP
To make a loop-free and redundant network
using RSTP. RSTP is upward compatible with
legacy STP.

priority queues per port.
Multicast IGMP v1/v2 Snooping
Prevents unnecessary forwarding of
multicast packets to reduce multicast traffic.
Management
SNMP agent Supports SNMP v1 and v2c
Http server Forwarding
