Thông tin chi tiết

Switch Cisco SLM2048T-48


1.Đặc tính kỹ thuật

- Mã sản phẩm: SLM2048T-48

- 48 10/100/1000 Mbps + 2 Combo mini-GBIC ports.

- Performance: Switching capacity 100 Gbps.

- Layer 2: Port grouping up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation, Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs), Head-of-line (HOL) blocking HOL blocking prevention.

- Internet Group Management Protocol(IGMP) versions 1 and 2 snooping: IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups.

- QoS: Priority levels 4 : hardware queues, Scheduling: Priority queuing and weighted round-robin (WRR), Queue assignment based on DSCP and class of service (802.1p/CoS).

Layer 2 Switching

Spanning Tree:

Standard 802.1d STP support

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

Port Grouping:

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

·Up to 4 groups

·Up to 4 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation


Support for up to 128 VLANs simultaneously (out of 4096 VLAN IDs)

Port-based and 802.1Q tag-based VLANs

Voice VLAN:

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

Internet Group Management Protocol (IGMP) Versions 1 and 2 Snooping:

IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups

Head-of-Line (HOL) blocking:
