The use of the IEEE 802.1Q tagging for VLANs and per-port VLAN is supported.
Multiple VLANs per port allow access to shared resources by stations that belong to
different VLANs.
The use of the IEEE 802.1w standard for Rapid Spanning Tree Protocol (RSTP) provides
rapid convergence of the spanning tree in case of link failure.
The use of the IEEE 802.1x standard for port-based network security ensures that only
authorized clients get network access.
MAC security is supported.
Port redundancy is supported to increase link resiliency.
Inter-module redundancy is supported with one pair in a stack.
Link Aggregation Group (LAG) support provides resiliency, load balancing, and bandwidth
expansion.
LAG redundancy is supported through resiliency between two LAG groups.
Port mirroring of any switch port is supported.
RMON/SMON port statistics provide real-time top-down analysis of network traffic.
IP multicast filtering (snooping) filters multicast traffic to optimize network bandwidth.
Classification of ports as regular or valuable is supported so that if a link fails, notification is
generated for valuable ports only.
Layer 3 features
Note:
Layer 3 features are available only on the P333R and P330-ML switches.
Note:
Static, RIPv1, RIPv2, OSPF IP routing protocols are supported.
Equal cost routing is used for load balancing and redundancy.
Router redundancy (VRRP) is supported.
NetBIOS rebroadcasting is available for applications such as WINS that use broadcasting
but may need to also communicate with stations on other subnets or VLANs.
ICMP and ARP protocols are supported.
DHCP/BootP relay allows broadcast requests to be forwarded to servers.
Policy-based routing of packets provides enforcement of QoS and ACL rules.
