CISCO SX350X-12 T-D

TECHNICAL SPECIFICATIONS:

Layer 2 Switching

Spanning Tree Protocol

• Standard 802.1d spanning tree support

• Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

• Multiple spanning tree instances using 802.1s (MSTP); 16 instances are supported

Port grouping/link aggregation

• 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 LAG

VLAN

• Support for up to 4094 active VLANs simultaneously; port-based and 802.1Q tag-based VLANs; MAC-based VLAN

• Management VLAN

• Private VLAN with promiscuous, isolated, and community port

• Guest VLAN, unauthenticated VLAN, protocol-based VLAN, subnet-based VLAN, CPE VLAN

• Dynamic VLAN assignment using RADIUS server along with 802.1x client authentication

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.

Multicast TV VLANMulticast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR).Q-in-Q

VLANs transparently cross over a service provider network while isolating traffic among customers.

GVRP/GARP

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain.

Unidirectional Link Detection (UDLD)UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networks.DHCP Relay at Layer 2Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82.IGMP (versions 1, 2, and 3) snoopingInternet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 4K multicast groups (source-specific multicasting is also supported).IGMP querierIGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router.HOL blockingHead-of-line (HOL) blocking.
