Management Support
3.5.1
Configuration and Status
The LXT98x0 provides management control and visibility of the following functions:
Counter Reset and Zeroing
Auto-negotiation (Control, Status, Advertisement, Link Partner, and Expansion)
Device and Board Configuration
LED Functions
Source Address Tracking (per port)
Source Address Matching (per chip)
Device/Revision ID
3.5.2
SNMP and RMON Support
The LXT98x0 provides SNMP and RMON support through its statistics gathering function.
Statistics are gathered on all packets flowing through the device for each of the ports, including the
MII. The LXT98x0 maintains statistics for both the entire 10 Mbps and 100 Mbps repeaters,
independent of the speed setting of the MII ports. All statistics are stored in 32- or 64-bit registers.
Per-port counters include:
3.5.3
Source Address Management
The LXT98x0 provides two source address management functions per port: source address
tracking and source address matching. These functions allow a network manager to track source
addresses at each port, or to identify any port sourcing a particular address.
3.6
Requirements
3.6.1
Power
The LXT98x0 has four types of +3.3V power supply input pins: two digital (VCC, GND) and two
analog (VCCR, VCCT). These inputs may be supplied from a single source. Ferrite beads should
be used to separate the analog and digital planes. These supplies should be as clean as possible.
Each supply input should be decoupled to ground. Refer to
Table 9 on page 28
for power and
ground pin assignments, and to the
“
General Design Guidelines
”
on page 61
