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 TACACS+ 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
