Emerson PACSystems ™ Ethernet Switch SLM082

7. Traffic priority (5.1.12)

QoS strategy: Supports "strict priority" (high priority queue data is transmitted first until empty) or "8:4:2:1 weighted fair queue" (proportionally transmitting high/medium/low/lowest priority queue data).

Priority classification:

Port based: Assign a priority level of "high/medium/low/lowest" to each port.

Based on COS/802.1p: Map to level 4 queue according to the 802.1p field values (0-7) in the frame.

Based on TOS/DSCP: Map to level 4 queue according to the TOS/DSCP field values (0-63) in the IP header.

8. Security Configuration (5.1.14)

IP Security: Only allow IPs in the 'Secure IP List' to manage switches through Web/SNMP.

Port security: After enabling, the port is prohibited from learning new MAC addresses and only forwards MAC frames from the security list.

MAC blacklist: Discard frames with target MAC addresses in the blacklist to prevent specific devices from receiving data.

802.1x authentication: Radius server IP, authentication port (default 1812), billing port (default 1813), shared key, etc. need to be configured, supporting four authorization modes: port "Accept", "Reject", "Authorize", and "Disable".

9. Alarm and Monitoring (5.1.15-5.1.17)

System alarms: Supports SYSLOG (local/remote server logs), SMTP email alarms, and can be triggered by events such as "system cold start", "power status", "SNMP authentication failure", "redundant ring topology change", etc; The fault relay is triggered synchronously when an alarm is triggered, and the Fault LED is constantly on.

Status monitoring: View MAC address table (dynamic/static entries, support aging time setting), port statistics (data volume, error frames, etc.), system event logs (can be refreshed/cleared), port mirroring (copy source port TX/RX data to target port monitoring).
