|
Spanning Tree Protocol |
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 groups
● 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 networkwide zero-touch deployment of voice endpoints and call control devices. |
|||||||||||||||||||||
|
Multicast TV VLAN |
Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (also known as MVR) |
|||||||||||||||||||||
|
Q-in-Q VLAN |
VLANs transparently cross a service provider network while isolating traffic among customers |
|||||||||||||||||||||
|
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) |
Protocols for automatically propagating and configuring VLANs in a bridged domain |
|||||||||||||||||||||
|
Unidirectional Link Detection (UDLD) |
UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks |
|||||||||||||||||||||
|
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 1K multicast groups (source-specific multicasting is also supported) |
|||||||||||||||||||||
|
IGMP Querier |
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 |
|||||||||||||||||||||
|
Jumbo frames |
Up to 9K (9216) bytes |

|
Layer 3 |
||||||||||||||||||||||
|
IPv4 routing |
Wirespeed routing of IPv4 packets Up to 512 static routes and up to 128 IP interfaces |
|||||||||||||||||||||
|
Classless Interdomain 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 |
|||||||||||||||||||||
| Power over Ethernet (PoE) | |||
| 802.3af PoE, 802.3at PoE+, and 802.3xx 60W power are delivered over any of the RJ-45 ports within the listed power budgets | Switches support 802.3at PoE+, 802.3af, 802.3xx 60W, and Cisco prestandard (legacy) PoE. Maximum power of 60W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached. The total power available for PoE per switch is as follows: | ||
