|
|
| • |
Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic | |
| • |
Powerful QoS feature: supports the following congestion actions: strict priority (SP) queuing, SDWRR, and SP+SDWRR | |
| • |
Advanced classifier-based QoS: classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a per-port basis | |
|
|
| • |
Friendly port names: allow assignment of descriptive names to ports | |
| • |
Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI) | |
| • |
Manager and operator privilege levels: enable read-only (operator) and read-write (manager) access on CLI and Web browser management interfaces | |
| • |
Command authorization: leverages RADIUS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail | |
| • |
Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS | |
|
|
| • |
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports | |
| • |
Flow control: using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations | |
| • |
Jumbo packet support: supports up to 10k byte frame size to improve performance of large data transfers | |
| • |
High-density port connectivity: provides up to 48 fixed 10/100/1000BASE-T ports in an entry-level static Layer 3 switch | |
| • |
Ethernet OAM: provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network convergence times | |
|
|
| • |
Nonblocking architecture: up to 104 Gbps nonblocking switching fabric provides wire-speed switching with up to 77.4 million pps throughput | |
| • |
Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps ensure high levels of security and ease of administration without impacting network performance | |
| Resiliency and high availability | |
| • |
Separate data and control paths: increases security and performance | |
| • |
Spanning Tree/MSTP, RSTP: provides redundant links while preventing network loops | |
| • |
IEEE 802.3ad Link Aggregation Control Protocol (LACP): supports up to 26 trunks, each with 8 links per trunk; supports static or dynamic groups | |
| • |
Smart link: allows 50 ms failover between links | |
| • |
Intelligent Resilient Framework (IRF): creates virtual resilient switching fabrics, where two or more switches perform as a single Layer 2 switch and Layer 3 router; switches do not have to be co-located and can be part of a disaster-recovery system; servers or switches can be attached using standard LACP for automatic load balancing and high availability; simplifies network operation by eliminating the complexity of Spanning Tree Protocol, Equal-Cost Multipath (ECMP), or VRRP | |
|
|
| • |
8K MAC address table: provides access to many Layer 2 devices | |
| • |
VLAN support and tagging: support IEEE 802.1Q with 4,094 simultaneous VLAN IDs | |
| • |
IP multicast snooping: automatically prevents flooding of IP multicast traffic | |
| • |
Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) protocol snooping: effectively control and manage the flooding of multicast packets in a Layer 2 network | |
|
|
| • |
Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses | |
| • |
Dynamic Host Configuration Protocol (DHCP): simplifies the management of large IP networks; supports client; DHCP Relay enables DHCP operation across subnets | |
| • |
Loopback interface address: defines an address in Routing Information Protocol (RIP) and OSPF that can always be reachable, improving diagnostic capability | |
