Layer 2, 3 Switching |
|
|
Layer 2 Switching |
|
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 |
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 |
Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82 |
|
|
|
|
Internet Group Management Protocol |
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 |
|
|
Cabling type |
Unshielded twisted pair (UTP) Category 5 or better for 10BASE-T/100BASE-TX; UTP Category 5 |
|
Ethernet or better for 1000BASE-T |
