IEEE802.1Q/p, IEEE802.1X
Spanning Tree
IEEE 802.1d Spanning Tree, IEEE 802.1w Rapid Spanning Tree
Link Aggregation
IEEE 802.3ad LACP, up to 4 groups with up to 8 ports per group
VLAN
Port-based and IEEE 802.1Q tag-based VLANs
Number of VLANs
1,024 active VLANs (4,096 range)
Layer 3 Static Routing
Line rate routing for IPv4 packets with up to 64 static routes
Auto Voice VLAN
VLAN voice traffic is automatically assigned by OUI to a voice-specific VLAN and treated with appropriate levels
IGMP Snooping
IGMP (v1/v2/v3) snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the
requesters; supports 256 multicast groups
Head-of-Line (HOL) Blocking
Head-of-line (HOL) blocking prevention
Port Mirroring
Traffic on multiple ports can be mirrored to another port for analysis with a network analyzer
Security
IEEE 802.1X radius authentication, DHCP snooping, IP-MAC-Port binding, IP source guard, ARP inspection, STP root guard, STP BPDU guard, DHCP
relay, port security supports limited dynamic lock and locked MAC address, management access control
Storm Control
Broadcast, unknown-unicast, and multicast
QoS
– Priority Levels
4 hardware queues
QoS
– Class of Service
Port-based, IEEE 802.1p priority-based, IPv4/v6 IP DSCP-based
QoS
– Scheduling
Priority queuing and weighted round robin (WRR)
ACL
Support up to 512 rules for enhanced security and/or advanced QoS policy: allow, deny, or rate limit based on Layer1 to 4 protocol fields at packet
header level with MAC ACL and IP ACL
RMON
Embedded remote monitoring (RMON) software agent support for enhanced traffic management, monitoring, and analysis
Management Interface
Built-in Web UI for easy browser-based configuration (HTTP/HTTPS)
Other Management
Telnet (menu-driven), DHCP client, system log, configuration unload and backup via HTTP or TFTP, PING, dual images, SNTP
SNMP
SNMP version 1 and 2c
