Layer 2 Switching | |
Spanning Tree Protocol (STP) |
Standard Spanning Tree 802.1d Rapid Spanning Tree (RSTP) 802.1w |
G.8032 ERPS | <50ms ring protection for industrial high reliable application |
Aggregation |
Link Aggregation Control Protocol (LACP) IEEE 802.3ad; Up to 13 groups Up to 16 ports per group |
VLAN |
Support up to 4K VLANs simultaneously (out of 4096 VLAN IDs) Port-based VLAN 802.1Q tag-based VLAN |
IGMP v1/v2 snooping |
IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 1024 multicast groups (source-specific multicasting is not supported) |
Security | |
Secure Shell (SSH) Protocol |
SSH secures Telnet traffic in or out the switch, SSH v1 and v2 are supported |
Secure Sockets Layer (SSL), HTTPS |
SSL encrypts the http traffic, allowing advance secure access to the browser-based management GUI in the switch |
Port Security |
Locks MAC Addresses to ports, and limits the number of learned MAC addresses |
DHCP Snooping |
prevent unauthorized configuration and use of IP addresses, while providing support for IP Source Guard and ARP detection |
IP Source Guard | Prevents datagram with spoofed addresses from being in the network |
ARP Inspection | Prevent ARP spoofing attacks and ARP |
Storm control |
Prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on a port |
ACLs |
Support for up to 256 entries; Drop or rate limitation 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 |
Quality of Service | |
Hardware Priority Queue |
