DLCI Table Screen
You can access the DLCI Table screen (Figure 4.24) from the Frame Relay
Service Details Screen shown on page 4-16. This screen displays a table of all
DLCIs on a specific frame relay service along with their state and alarm
conditions.

Service Aware Screen
The Service Aware function recognizes IP traffic and counts the number of
frames and bytes passed for a specific service based on filters by DLCI, by IP
Address, and by IP Port. Each row of the Service Aware table represents a
specific set of filter parameters known as a “rule.” Each rule is established
through the Rule Config screen, which is accessed by selecting “Rule
Details.”
The Service Aware screen (Figure 4.25) provides a table showing these
filtered packet counts for up to 10 rules. This table indicates which Service
Aware filters are enabled or disabled, and shows the specific DLCI, IP
Address, and IP Port by which the IP traffic is filtered. In addition, this table
shows the Tx Alarm Threshold and the current Tx Alarm status (if enabled)
for each rule.
It is also possible to filter PPP services, in which case all information related
to DLCIs is ignored.
