Software features
The CE0128T Switch has the following software features:
Scalability and performance:
Media access control (MAC) address learning
Static and LACP (IEEE 802.3ad) link aggregation groups (LAGs)
Broadcast storm control
IGMP snooping for limit flooding of IP multicast traffic
IGMP filtering to control multicast traffic for hosts participating in multicast groups
Configurable traffic distribution schemes over LAGs based on source/destination IP or MAC
Availability and redundancy:
IEEE 802.1D STP for providing L2 redundancy
IEEE 802.1s Multiple STP (MSTP) for topology optimization
IEEE 802.1w Rapid STP (RSTP) (rapid convergence for delay-sensitive traffic such as voice)
Rapid Link Detection Protocol (RLDP) for L2 link failure detection
VLAN support:
Port-based and protocol-based VLANs
Up to 4094 VLANs supported per switch
802.1Q VLAN tagging support on all ports
802.1Q-in-Q VLAN tunneling
802.1x with dynamic VLAN assignment
Private VLANs
Stacking:
Up to 8 switches in a stack
Single IP management
Less than 100 milliseconds failover time in case of a member switch failure
Line and ring stacking topologies
Link aggregation across member devices
Multi-Active Detection (MAD) via bi-directional forwarding detection (BFD) or link aggregation
Security:
MAC-based and IP-based access control lists (ACLs)
802.1x port-based network access control
Multiple local user IDs and passwords
User access control
Radius and authentication and authorization
Protection from Denial of Service (DoS) attacks
DHCP snooping (IPv4/IPv6)
Quality of Service (QoS):
IEEE 802.1p, IP ToS/DSCP, MAC/IP, and port traffic classification and processing
Traffic shaping and re-marking based on defined policies
Eight priority queues per port for processing qualified traffic
Strict-Priority (SP) scheduling
Weighted Round Robin (WRR) scheduling
Weighted Fair Queueing (WFQ) scheduling
IPv4/IPv6 ACL metering
IP v4 Layer 3 functions:
Host management
IP filtering with ACLs
Static routes
DHCP server, client and relay operations
IGMP v1/v2 snooping
