Pagina nueva 1 MAC Table Up to 8192 MAC addresses Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support, enabled by default Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]) Multiple Spanning Tree instances using 802.1s (MSTP) 16 instances are supported 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 Load balance based on source and destination MAC address, or source and destination MAC/IP VLAN Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN Auto Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS QinQ VLAN VLANs transparently cross a service provider network while isolating traffic among customers Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) Protocols for automatically propagating and configuring VLANs in a bridged domain Head-of-Line (HOL) Blocking HOL blocking prevention Jumbo Frame Frame sizes up to 9216 supported Security ACLs Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag Support up to 512 rules Port Security Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses IEEE 802.1x (Authenticator Role) 802.1X: RADIUS authentication; guest VLAN; multiple host mode RADIUS, TACACS+ Supports RADIUS and TACACS authentication; switch functions as a client MAC Address Filtering Supported Storm Control Broadcast, multicast, and unknown unicast DoS Protection DOS attack prevention STP Bridge Protocol Data Unit (BPDU) Guard This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
