|
|
Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP) |
|
|
Up to 8 groups |
|
|
Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation |
|
|
VLAN: |
|
|
Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs) |
|
|
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 |
|
|
Voice Lan: |
|
|
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
|
|
Generic VLAN Registration Protocol (GVRP)/ Generic Attribute Registration Protocol (GARP): |
|
|
Protocols for automatically propagating and configuring VLANs in a bridged domain |
|
|
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2: |
|
|
Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82 |
|
|
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping: |
|
|
IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups (source-specific multicasting is also supported) |
|
|
IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router |
|
|
Head-of-line (HOL) blocking: |
|
|
HOL blocking prevention |
|
|
Layer 3 |
IPv4 Routing: Wirespeed routing of IPv4 packets Up to 32 static routes and up to 32 IP interfaces Classless Inter-Domain Routing (CIDR): Support for CIDR 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 |
|
Security |
Secure Shell Protocol (SSH): SSH secures Telnet traffic to and from the switch; SSH v1 and v2 are supported |
|
Secure Sockets Layer (SSL): SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
|
|
IEEE 802.1X (Authenticator role): RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions |
|
|
Supports time-based 802.1X |
|
|
Dynamic VLAN assignment |
|
|
Layer 3 isolation: Allow / disallow routing between IP subnets or directly connected IP networks |
|
|
Layer 2 isolation Private VLAN Edge (PVE) with community VLAN: PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks |
|
|
Port security: Locks MAC addresses to ports, and limits the number of learned MAC addresses |
|
|
RADIUS/TACACS+: Supports RADIUS and TACACS authentication. Switch functions as a client |
|
|
Storm control: Broadcast, multicast, and unknown unicast |
|
|
DoS prevention: DoS attack prevention |
|
|
Congestion avoidance: |
|
|
A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization |
|
|
ACLs: Support for up to 512 rules |
|
|
Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag |
