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 7 groups;Up to 14 ports per group |
| VLAN | Support up to 4K VLANs simultaneously (out of 4096 VLAN IDs) ;Port-based VLAN; 802.1Q tag-based VLAN |
|
DHCP Snooping (Layer 2) |
Prevent unauthorized configuration and use of IP addresses, while providing support for IP Source Guard and ARP detection |
| 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 |
| IP Source Guard | Prevents datagram with spoofed addresses from being in the network |
| 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 | Support 8 hardware queues |
| Scheduling |
Strict priority and weighted round-robin (WRR) Queue assignment based on DSCP and class of service (802.1p/ CoS) |
| Classification | Port based; 802.1p(PCP) VLAN priority based; IPv4/IPv6 precedence/ type of service (ToS) / DSCP based; |
| Rate Limiting | Ingress policer; egress shaping and rate control; per VLAN, per port and flow based |
|
Management (Web/ SSL, Telnet/ SSH, ping, Trivial File Transfer Protocol (TFTP), SNMP, Syslog) |
|
| Web GUI interface | Built-in switch configuration utility for browser-based device configuration (HTTP/ HTTPs). Supports configuration, system dashboard, maintenance, and monitoring |
| Dual Image | Dual image provides independent primary and secondary OS files for backup while upgrading |
| Firmware upgrade |
Web browser upgrade (HTTP/ HTTPs) and TFTP; Upgrade through console port as well |
| Port mirroring | Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to N-1 (N is Switch’s Ports) ports can be mirrored to single destination port. A single session is supported. |
| Other management | Single IP management; HTTP/HTTPs; SSH; RADIUS; DHCP Client; SNTP; cable diagnostics; ping; syslog; Telnet client (SSH secure support) |
| Green Ethernet | |
| Link detection | Compliant IEEE802.3az Energy Efficient Ethernet Task Force. Automatically turns off power on Gigabit Ethernet RJ-45 port when detecting link down or Idle of client. Active mode is resumed without loss of any packets when the switch detects the link up |
| Cable length detection | Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter. |
