Feature Descriptions
Key LIB-4xxx features include:
Up to 4096 Service Classification entries; and up to 4096 service-specific egress tagging and QoS
entries.
Layer 2 Switching features (802.1Q VLAN switch with 32k MACs and 4k VLANs, Push/pop/translate
up to two VLAN tags on ingress and/or egress; Policing with leaky bucket storm control and
protection from broadcast, flooding, and multicast. RSTP, MSTP, IVL and hardware- and software-
based Learning. Up to 512 QoS, VLAN, and Security Profile Classification entries.
L2 Multicast features (32k Layer 2 Multicast Groups with up to 1k port masks; IGMP v2 and v3
support, and MLD v1 and v2 support).
Quality of Service (Eight QoS class queues per port with Strict or DWRR scheduling; four DP levels
per QoS class queue; WRED operation between DP levels within each QoS class queue for
intelligent congestion avoidance per QoS class.
Security (content aware filtering engine using ACLs for frame/packet inspection; generic storm
control for flooded broadcast, flooded multicast, and flooded unicast traffic. Eight selectable CPU
ports for segregation of CPU redirected traffic. Per-port and per-address registration of snooping of
reserved IEEE Mac addresses (BPDU, GARP). Port-based and MAC-based access control (IEEE
802.1X). Per-port CPU-based learning with option for secure CPU-based learning. Per-port ingress
and egress monitoring.
RMON statistics group (RFC 2819) support and SNMP interface group (RFC 2863).
Carrier Ethernet features (Provider bridge switch for 32K MACs and 4K VLANs).
