VLAN Monitoring
The NAM extends RMON capabilities to VLANs by implementing the Switch Monitoring (SMON) standard, a
specification for monitoring switched networks. Like RMON, SMON also collects data by analyzing the
headers in packets and aggregating them by VLAN ID. Utilizing SMON, the NAM offers the ability to collect
and report resource utilization by VLAN and it also supports the simultaneous monitoring of multiple VLANs.
With this feature, you can view traffic and priority statistics by VLAN and use this to determine if further drill
down is necessary. The NAM also stores individual RMON statistics for each VLAN to support multiple
management activities at any given time.
