Management
|
|
Web user interface
|
Built-in web user interface for easy browser-based configuration (HTTP/HTTPS)
|
|
SNMP
|
SNMP versions 1 and 2c with support for traps
|
|
SNMP MIBs
|
RFC1213 MIB-2, RFC2863 interface MIB, RFC2665 Ether-like MIB, RFC1493 bridge MIB, RFC2674 extended bridge MIB (P-bridge, Q-bridge), RFC2819 RMON MIB (groups 1, 2, 3, and 9 only), RFC2737 entity MIB, RFC 2618 RADIUS client MIB
|
|
RMON
|
Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.
|
|
Firmware upgrade
|
• Web browser upgrade (HTTP)
• Trivial File Transfer Protocol (TFTP) upgrade
|
|
Port mirroring
|
Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe.
|
|
Other management
|
• RFC854 Telnet (menu-driven configuration)
• SSH and Telnet management
• SSL security for web user interface
• Dynamic Host Configuration Protocol (DHCP) client
• Simple Network Time Protocol (SNTP)
|
|
Security Features
|
|
IEEE 802.1X
|
802.1X - RADIUS authentication. MD5 encryption
|
|
Access control
|
• MAC source address (SA)/destination address (DA)
|
|
Availability
|
|
Link aggregation
|
• Link aggregation using IEEE 802.3ad Link Aggregation Control Protocol (LACP)
• Up to 8 ports in up to 8 trunks
|
|
Storm control
|
Broadcast, multicast, and unknown unicast
|
|
Spanning Tree
|
IEEE 802.1d Spanning Tree, IEEE 802.1w Rapid Spanning Tree, Fast Linkover
|
|
IGMP snooping
|
IGMP (version 1 and 2) snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.
|
|
QoS Quality of Service
|
|
Priority levels
|
4 hardware queues
|
|
Scheduling
|
Strict priority and weighted round-robin (WRR)
Queue assignment based on DSCP and class of service (802.1p/CoS)
|
|
Class of service
|
Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/type of service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS.
|
|
Rate limiting
|
Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based.
|
|
Congestion avoidance
|
A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.
|
|
Class of service (CoS)
|
• 802.1p VLAN priority-based CoS
• IPv4 ToS/IP precedence-based CoS
|
|
Layer 2
|
|
Spanning Tree Protocol (STP)
|
Standard 802.1d Spanning Tree support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
8 instances are supported
Multiple Spanning Tree instances using 802.1s (MSTP)
|
|
Port grouping
|
Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
? Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
|
|
VLAN
|
Support for up to 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLAN
Management VLAN
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
Guest VLAN Unauthenticated VLAN
Dynamic VLAN assignment via Radius server along with 802.1x client authentication
CPE VLAN
|
|
Voice VLAN
|
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS.
Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices.
|
|
Layer 3
|
|
IPv4 routing
|
Wirespeed routing of IPv4 packets
Up to 512 static routes and up to 128 IP interfaces
|
|
Classless Inter-Domain Routing (CIDR)
|
Support for CIDR
|
|
Layer 3 Interface
|
Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface
|
|
DHCP relay at Layer 3
|
Relay of DHCP traffic across IP domains
|
|
User Datagram Protocol (UDP) relay
|
Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP packets
|
|
DHCP Server
|
Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options
