Remote Monitoring (RMON)
Dell Networking operating software remote monitoring (RMON) is based on IEEE standards, providing both 32-bit and 64-bit
monitoring and long-term statistics collection.
RMON supports the following RMON groups, as defined in RFC-2819, RFC-3273, RFC-3434, and RFC-4502:
● Ethernet Statistics Table; RFC-2819
● Ethernet Statistics High-Capacity Table; RFC-3273, 64bits
● Ethernet History Control Table; RFC-2819
● Ethernet History Table; RFC-2819
● Ethernet History High-Capacity Table; RFC-3273, 64bits
● Alarm Table; RFC-2819
● High-Capacity Alarm Table (64bits); RFC-3434, 64bits
● Event Table; RFC-2819
● Log Table; RFC-2819
● User History Control Table; RFC-4502
● User History Object Table
● User History Table

RMON does not support the following statistics:

NOTE:
Only SNMP GET/GETNEXT access is supported. Configure RMON using the RMON commands. Collected data is
lost during a chassis reboot.
